Abstract
A method of image rendering quality prediction and path planning for large-scale scenes is provided. In the method, multiple surface points of a proxy model within a viewpoint range of a virtual viewpoint are obtained. For each surface point, a photometric error among multiple photometric information corresponding to the surface point is determined. The multiple photometric information refers to the photometric information of the surface point at multiple visible acquisition viewpoints respectively. The visible collection viewpoint are those acquisition viewpoints where the surface point is visible among the multiple acquisition viewpoints. Based on the photometric error, a viewing angle similarity and a resolution similarity between the virtual viewpoint and the visible acquisition viewpoints with respect to the surface point are determined. A rendering quality information of the proxy model at the virtual viewpoint is determined based on the viewing angle similarities and the resolution similarities.
