Title:
FAST THREE-DIMENSIONAL SPACE PROJECTION AND PHOTOGRAPHING VISUAL IDENTIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/094697
Kind Code:
A1
Abstract:
The present invention discloses a fast three-dimensional space projection and photographing visual identification system, comprising multiple projection acquisition modules and processing modules, in which all of the projection acquisition modules are connected to the processing modules; each of the projection acquisition modules consists of a projection module and a camera module, and each of the processing modules consists of a projection image and camera image processing unit, a scene object identification and path identification unit, a path selection and motion control unit and a 3D image modeling unit. The present invention combines projection technology with digital photographing technology, and uses a digital camera for photographing a distorted grid pattern generated from projection onto a 3D scene, thus reducing a data acquisition amount; grid distortion is used for performing spatial scene identification, thus reducing the calculation difficulty and increasing the 3D modeling speed. The present invention can also be applied to the identification of 3D spaces and scene objects by a fast moving apparatus, and is in particular applicable to unmanned drones, unmanned driving devices, motion path analysis of robots, and 3D identification of moving objects.
