Title:
DISPLAY METHOD AND SYSTEM FOR VEHICLE-MOUNTED AVM, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/017528
Kind Code:
A1
Abstract:
A display method and system for a vehicle-mounted AVM, and an electronic device and a storage medium. The display method is implemented on the basis of a plurality of vehicle-mounted lenses and comprises: constructing a coordinate mapping table, wherein the coordinate mapping table is used for representing a coordinate mapping relationship between a panoramic image obtained by performing stitching on the basis of original images collected by a plurality of vehicle-mounted lenses, and the original image collected by each vehicle-mounted lens; generating the panoramic image on the basis of the original images collected by the plurality of vehicle-mounted lenses and the coordinate mapping table; mapping the panoramic image into a preset world model, so as to construct a virtual world inside the preset world model; placing a vehicle model at a position in the virtual world that corresponds to a real vehicle; and rendering and outputting a picture in the virtual world that corresponds to a specified viewpoint, wherein the viewpoint is located on the preset world model and faces the center point of the vehicle model. An end-to-end coordinate mapping table constructed by means of the method can prevent a plurality of image interpolations from occurring, and the construction of a virtual world facilitates the realization of a real-time preview.
