Technical Field

The present disclosure relates generally to a systems and method for generating an image file of a high resolution 3D automotive glazing and in particularly, to an apparatus for realistic 3D rendering, and more particularly to an apparatus for realistic 3D rendering capturing the optical, thermal and visual properties of the vehicle and automobile glazing.

Background

[0001] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art.

[0002] 3D rendering is a growing technology used in architecture, manufacture, clothing, automobile and the like. 3D rendering is two dimensional representation of a computer wireframe model that has been given properties such as texture, color, and material. 3D visualization is created using two primary software pillars: modelers and renderers. Every rendering starts as a 3D model, which is represented by a series of flat geometric shapes connected together in three dimensional space. These shapes are called polygons. The models themselves are often very crude, represented in the digital space as a simple wire-frame object or scene. In order to give these shapes real form, they must be introduced to texture maps, artificial light sources, and a number of other filters that turn out at the other end what amounts to a finished 3D rendering.

[0003] 3D renders may include photorealistic effects or non-photorealistic rendering. In photorealism, an object is replicated in a rendered environment with features and characteristics of the original objects. Such photorealistic rendering is typically implemented in garment industry to visualize the texture of the fabric. Rendering is also done in real-time using cameras to capture the object and create a 3D environment.

[0004] Typically, capturing texture of an object is performed using camera as mentioned in prior art WO2017029487. However, the method does not capture the properties of the object precisely, and the properties also vary with change in camera settings and light conditions. Thus, there exists need for a system that can capture the properties of the object precisely for realistic rendering.

[0005] Another prior art, US20090153673 teaches a method and apparatus for measuring 3D graphical model using images. The method includes mearing optical and visual properties of the actual object to achieve similar properties in the 3D model. Further, the rendered output is analyzed to determine the variation in the product. However, the prior art does not teach about measuring actual properties of the object to generate a realistic rendering.

[0006] Thus, there exists need for a rendering system and method that captures the physical properties of the object to generate physical realistic renders. Further, there exists need for a rendering system and method that is exclusively designed for automotive glazing’s. Furthermore, there exists need for a system and method that allows a user to compare various rendered objects to determine the performance of the object in varied surroundings.

The physical realistic three-dimensional model defines the properties of the object in varied environments and camera angles. Examples of properties of the object include optical properties, thermal properties and acoustic properties. [0008] According to an embodiment of the disclosure, a system for realistic three dimensional rendering of automotive vehicle glazing and depositing coating layers on the glazing is disclosed. The system includes a measurement device, an input device, a modeling device, a rendering device, a data storage module and a deposition module. The measurement device is configured to measure and visual and optical properties of an object. The input device is configured to receive parameters from a user corresponding to the rendering properties of the object. The modelling device is configured to obtain output from the measurement device and the input device and generate a rendering file format. The rendering device is configured to receive the rendering file format.

The rendering device generates a physical realistic view of the realistic three-dimensional model, which is further displayed on the display unit. Lastly, the deposition module is coupled to the display unit and configured to deposit a coating layer on the object based on the received user parameters and the output from the rendering device.

[0009] According to an embodiment of the disclosure, a method for real-time deposition of material on a object using a realistic three dimensional Tenderer is disclosed. In accordance with the method, the visual and optical properties of a object are measured using a measurement device. The properties are values obtained from the measurement device including but not limited to functional values, LAB color, reflection and transmission color on all angles. Thereafter, a set of parameters are received from a user, through an input device corresponding to the rendering properties of the object. Combining the visual, optical properties and the parameters, a rendering file format is generated by a modelling device. The output data received from the measurement device, the modelling device, and the rendering device are stored in a data storage module. The three-dimensional model is generated by a creating a 3D shell and/or a UV map based on the rendering file format. The rendering file format is received by the rendering device to generate a realistic three-dimensional model of the object. Finally, a physical realistic view of the object is provided in a display unit. Subsequently, a rendering environment is generated for positioning the object based on external parameters such as view angle, background, lighting, sky conditions and color. Ultimately, the 3D shell or model is mapped onto the rendering environment with physical textures. The physical textures of the object comprise luminosity, color, lighting, specularity and diffusivity.

FIG. 1A is a block diagram illustrating a system for rendering realistic three-dimensional models. The system comprises measurement device 102, modelling device 104, rendering device 106, data storage module 108 and input device 110. The measurement device 102 is used to measure and visual and optical properties of an object. In an example, the measurement device 102 is a spectrophotometer, angular spectrophotometer, camera, and sensors. The device collects three co-efficient of samples. The optical data of the glass is measured at 5 angles such as 15 degree, 30 degree, 45 degree, 60 degree and 75 degree to obtain reflection and transmission coefficients. In another example, the measuring device measures the coefficients at multiple points over a 360-degree angle. The physical data captured by the spectrophotometer includes transmission, reflection, refraction and related optical properties of the object, for ex. glazing. In an example, the measurement device such as camera combined with image editing tool is utilized to capture the realistic textural properties of the surface. The aforementioned data is used to generate normal and bump maps which is applied for rendering.

[0032] The obtained values are further converted into a rendering material format supported to replicate the properties and characteristics of the glass. The measurement device measures the glass samples and other objects using the spectrometer on a real time basis with all 360 degrees. The output values obtained from the measurement device include at least one of but not limited to functional values, LAB color, reflection and transmission color on all angles. In an example, the measurement device generates output values corresponding to the physical glass samples and output is material file with accurate measured values of the glass samples.

[0033] The modelling device 104 generates a rendering file format from the output values (collected by measurement device). The rendering file format is applied to the glass object during three-dimensional modeling. The rendering file includes information about the material properties and characteristics. The modelling device 104 generates a 3D model by creating and exporting a 3D model of the desired object with its appropriate measured dimensions. The modelling device also receives inputs from the user through the input device 110. User input includes rendering properties of the object, transmission, angle of view, luminosity, color, lighting, specularity and diffusivity. The input device 110 communicates with the modelling device 104 through a wired or a wireless communication protocol. Examples of input device 110 include a microphone, a keyboard, a touch screen, a bar code reader, and a gesture unit. Thereafter, the modelling device 104 positions the 3D model of the object in a specific camera angle and environment. The environment is generated by defining background, sky conditions and lighting (HDR). The 3D model generated by the modeling device incorporates material properties, physical textures, and render settings.

[0034] In an embodiment of the disclosure, the Rendering device validates the model to be rendered, and adjusts the resolution of the 3D model. The rendering device generates a realistic three-dimensional model of the object based on the output from the measurement device and the input device. The rendering device provides a physical realistic view of the 3D model with Front, side, back, perspective, top, interior along with panorama views of the object. The rendering device transmits the physical realistic view to a display unit 110. The display unit 110 is at least one of a mobile device, computing device, or an augmented reality device providing realistic view of the rendered object. The display device enables a user to visualize the properties of the object in varied environments and camera angles.

[0035] In an embodiment of the present disclosure, a plurality of rendered objects is created with varied samples of the object by the modeling device and stored in a remote server 114. The plurality of rendered objects is used by the rendering device for creating output in varied environment conditions and camera angles. The remote server 114 is a cloud based server or an application server.

[0036] In another embodiment, the system for rendering 3d objects is used for visualizing the thermal profile of a vehicle. In accordance with the present disclosure, the measurement device 102 is configured to receive thermal measurement of the vehicle. The thermal measurements are captured by a plurality of wireless sensors positioned in the vehicle. The thermal measurements are transmitted to the modelling device 104. The measurement device also estimates contour of the interiors of the car. The modelling device 104 receives the output from the measurement device 102 and determines the thermal plane of the vehicle. The thermal planes are divided into the middle of the car, middle point of right seat, and middle point of left seat. Further, the modelling device 104 maps thermal measurements onto various thermal planes to generate thermal planes. A plurality of thermal planes (as shown in FIG. IB) is generated for varying environmental conditions and stored in data storage module 108. The modelling device 104 overlays the thermal maps onto the thermal planes using UV coordinates. The render settings are fed into the system to obtain a scene consisting the vehicle and thermal planes (as shown in FIG. 1C)

[0037] The rendering device 106 receives the output of thermal maps from the modelling device. Thereafter, the rendering device renders the car model without the thermal plane and the second attempt renders including the thermal plane. The two images are further post processed to create a transparent thermal plane on the vehicle.

[0038] The rendering device 106 transmits the rendered output to the display unit 110. The display unit 110 includes an interactive touch interface that allows the user to hover around the rendered output 110 with thermal planes of the vehicle. The thermal planes of the vehicle varies with each type of glazing used in the car. The user is enabled to select a glazing type of the windshield, backlight and sidelights to view the rendered thermal planes for the selected glazing type. The rendered output on the display unit 110 varies for each glazing type to indicate different thermal planes. A plurality of such rendered output is stored in the data storage module 108 through a network or cloud. The data storage module 108, may be a server.

[0039] The display unit 110 enables the user to select one or more types of glazing, compare and visualize the aesthetic looks, optical, and thermal properties of the glazing. The rendering system with display unit 110 may select a glazing type for rendering based on the HVAC information provided by the user and the geolocation data. The display unit 110 informs the user about the thermal asymmetry and thus assist in selecting the sidelight and backlit to mitigate risk.

[0040] In another embodiment of the present disclosure, the outputs are imported into a custom designed digital application for mobile platforms. This application has features to vary the type of glass products, camera angles, sky conditions and environment. This also enables the viewer to compare products after making variations within the platform.

[0041] In another embodiment of the present disclosure invention also encompasses panoramic view of the physical realistic rendered output from exterior and interior to make the viewer to have a look and feel of the glazing. This is also accompanied along with VR experience of the same by integrating them with the VR app. The Virtual reality experience of the rendered model enhances the customer experience in making choices among the wide range of products in the database which is replicating the physical realism of the actual product. The customer delight is achieved and does not falsify the impression/aesthetics of the end.

[0042] FIG. ID is a block diagram illustrating a system for realistic three dimensional rendering of automotive vehicle glazing and depositing coating layers on the glazing,. With respect to FIG.1B, the system includes a scanning device 116 that is configured to scan the object and further convert the scanned object into a 3D shell. The scanning device 116 includes a plurality of sensors including Charge-coupled device (CCD), CMOS (Complementary metal oxide semiconductor) and the like. In an example, the scanning technique can be used to capture shape and dimensions of an automobile and thereafter render a three-dimensional model of the automobile with a selected glazing or laminate or windshield. The rendered model of the automobile indicates the functional properties of the glazing or windshield in various lighting, color and camera angles.

[0043] In an example, the system is configured to create a panoramic view. The panoramic view is created by rendering a 360-degree panoramic image and wrapping it in the virtual sphere, where the camera is positioned in the center of the sphere. This enables the user to turn around the image and visualize all around. The different views are achieved by placing multiple hotspots around the car. The hotspots are placed using the multiple layered images. Each hotspot is linked to the images in each layer. The different hotspots open the corresponding image to the desired camera angle. In another example, the system is used to provide an augmented realistic view. The augmented view is developed using a custom program defining the visual and optical properties and 3d geometry of the glazing. The augmented content is overlaid on the real time environment suiting appropriate lighting conditions.

[0044] In an embodiment of the present disclosure, the data storage module 108 is wirelessly coupled to a remote server 114. The remote server 114 is one of a cloud storage, application server, data server and the like. The remote server 114 stores a plurality of rendering files corresponding to the plurality of facade types, windshield type and the like. The remote server 114 also stores a plurality of car models, color options, texture options, environment/background options and the like.

[0045] In an embodiment of the present disclosure, the system includes a deposition module 112. The deposition module 112 is configured to receive output from the display unit and perform coating deposition in real-time based on the rendered design and color of the object. In an example, the deposition module is a laser printer. The coating occurs by dip/spray coating process, where the corresponding metal oxides synthesize to form the color data obtained from the rendered output. The optical properties defined in the system determines the thickness and the number of coating layers to be deposited. The coating applicator ejects the metal oxide on the glass surface to be coated

[0046] In another example, the coating deposition may be obtained by screen printing where the design is made on a screen and later the combination of ceramic powder and filler is applied over the object. With respect to the user input and the display output, a coating layer is deposited on the substrate/object. In an example, if the substrate is a glass, a coating layer of metal or metal oxide, and ceramic is deposited on the glass to suit the requirements of the user.

[0047] In an example, a vehicle with a specific type of windshield is to be rendered. The type of the automotive vehicle is rendered by processing stored values from the remote server 114. Further, the rendered model of the windshield type is generated by applying material characteristics (retrieved from the remote server 114). Further, the system enables a user with options for adjusting transmission values, reflective values, texture, finish and color of the vehicle. Thereafter, the environment data corresponding to road, sky, are also generated or added to the rendered object through images. The rendering files corresponding to various glass types such as TSA-NX, TSA 3+, VV55, SCN 450 are stored in the remote server 114.

[0048] In another example, the system provides a realistic 3D view with a comparator tool. The system allows to select a first product type from the database/server, and a second product type from the database/server. Thereafter, both rendered view of both the first product type and the second product type are displayed simultaneously alongside each other on a graphical interface. The comparator tool enables a user to view and compare the difference in properties, reflection and transmission between two products.

[0050] The data processing unit 118 comprises the measurement device 102, the modelling device 104 and the rendering device 106. The operation in the data processing unit 118 is executed by a processor. The processor may be any conventional processor, such as commercially available CPUs or hardware -based processor. It will be understood by those of ordinary skill in the art that the processor, computer, or memory may actually comprise multiple processors, computers, or memories that may or may not be stored within the same physical housing. Further, processor is one of the component of the rendering device and transmits commands to the display unit. The memory is configured to store instructions accessible by the processor. Further, the memory includes data that is executed by the processor. Memory is any storage device, a computer-readable medium, or another medium that stores data that may be read with the aid of an electronic device, such as a hard-drive, memory card, ROM, RAM, and write-capable or read-only memories. [0051] The processor is configured to receive user parameters through the input device and transmit output signals to the display unit and the deposition module via a communication module. The processor is also configured to communicate with external devices, servers via the communication module. The processing unit can have wired or wireless communication with the output device.

Inn

[0053] In an embodiment, the data processing unit 118 further controls coating of conductive material on the glazing based on the generated realistic 3D model. The output requested by the customer is instantly processed in the data processing unit which commands the deposition module to apply coating on the object. The corresponding color output similar to the rendered value is deposited and demonstrated to the customers instantly which is achieved thorough the combination of the data processing unit and coating deposition module. The deposition module detects the RGB value of the coating color from the rendered image. The deposition module has preset metal oxides in the chamber to which is synthesized according to the RGB value. The synthesized metal oxide is further applied on the object to achieve the actual color of the coating on glass intended.

[0054] In an embodiment of the present invention, the deposition module is a laser printer. The technology used is ink synthesis, where a combination of ceramic powder and filler is used for printing a rendered design and pattern. The laser printer deposits the conductive material in desired design pattern on the glazing. In another example, the deposition module can be a screen printer.

Other embodiments may be used and derived from the disclosure, such that a structural substitution, logical substitution, or another change may be made without departing from the scope of the disclosure. Accordingly, the disclosure is to be regarded as illustrative rather than restrictive.

[0071] The description in combination with the figures is provided to assist in understanding the teachings disclosed herein, is provided to assist in describing the teachings, and should not be interpreted as a limitation on the scope or applicability of the teachings. However, other teachings can certainly be used in this application.

[0072] As used herein, the terms "comprises," "comprising," "includes," "including," "has," "having" or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a method, article, or apparatus that comprises a list of features is not necessarily limited only to those features but may include other features not expressly listed or inherent to such method, article, or apparatus. Further, unless expressly stated to the contrary, "or" refers to an inclusive-or and not to an exclusive-or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0073] Also, the use of "a" or "an" is employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the disclosure. This description should be read to include one or at least one and the singular also includes the plural, or vice versa, unless it is clear that it is meant otherwise. For example, when a single item is described herein, more than one item may be used in place of a single item. Similarly, where more than one item is described herein, a single item may be substituted for that more than one item.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The materials, methods, and examples are illustrative only and not intended to be limiting. To the extent that certain details regarding specific materials and processing acts are not described, such details may include conventional approaches, which may be found in reference books and other sources within the manufacturing arts.

[0075] While aspects of the present disclosure have been particularly shown and described with reference to the embodiments above, it will be understood by those skilled in the art that various additional embodiments may be contemplated by the modification of the disclosed machines, systems and methods without departing from the spirit and scope of what is disclosed. Such embodiments should be understood to fall within the scope of the present disclosure as determined based upon the claims and any equivalents thereof.
