Post-processing based image texture projection method, system, device and medium

Abstract

The application relates to a post-processing-based image texture projection method, system, device and medium. The method comprises the following steps: acquiring an observation viewpoint and camera parameters of a main camera, calculating an observation cone range of the main camera according to the observation viewpoint and the camera parameters; screening one or more target models located in the observation cone range from a scene according to the observation cone range; determining a visual contour of the target model under the visual angle of the main camera according to the relative position relationship between the target model and the main camera; performing a clipping operation on the visual contour to obtain a projection contour corresponding to a screen display area; and mapping a specified texture image to the projection contour according to a preset texture projection rule. According to the method, the target model is screened from the scene according to the observation cone range, the target model is clipped to obtain the projection contour, and then the texture projection is performed only on the projection contour, so that the calculation amount can be effectively reduced, the GPU resource can be saved, and the running smoothness is improved.
