Abstract: The embodiments of the present invention provide a method and a device for determining scoring models of a three-dimensional animation scene frame, the method comprising: obtaining a dataset of three-dimensional animation scene frames; obtaining a predetermined stereoscopic effect standard score and a predetermined visual comfort standard score corresponding to each three-dimensional animation scene frame; obtaining the disparity map of each three-dimensional animation scene frame, extracting disparity statistic features of each three-dimensional animation scene frame based on its disparity map, and combining the disparity statistic features into one feature vector; and, determining the stereoscopic effect scoring model and the visual comfort scoring model for a three-dimensional animation scene frame respectively based on the feature vector of each three-dimensional animation scene frame in conjunction with the corresponding stereoscopic effect standard score and visual comfort standard score, in order to achieve the automatic scoring of three-dimensional animation scene frames and reduce the influence of subjective factors from the producers on the scoring. The workload is also reduced and the efficiency is improved.

Abstract: A method and a system for determining parameters of an off-axis virtual camera provided by embodiments of present invention can extract a scene depth map for each video frame from a depth buffer, determine the minimum value of edge depth values of the scene depth map as the closest scene edge depth of each video frame, determine the depth of a first object as the depth of an object of interest of each video frame, use the smaller value between the closest scene edge depth and the depth of an object of interest as the zero-parallax value and obtain a zero-parallax value sequence constituted by the zero-parallax value of each video frame. The present invention realizes automatic determination of the zero parallax of each video frame rather than manual setting thereof, and thus the determination will not be affected by factors such as lack of experience, and the amount of work for an technician is also reduced. Meanwhile, the present invention makes the zero parallax as close as possible to an object of interest without incurring the window occlusion problem, which can improve the stereo perception as much as possible while ensuring the comfortability, and can ensure the using effect of the determined zero parallax.
