Off-axis virtual camera parameter determination method and system

Abstract

The embodiment of the invention provides an off-axis virtual camera parameter determination method and system. By employing the method and the system, a scene depth map of each video frame can be extracted from a depth buffer area; the minimum value of edge depth values of the scene depth map is determined as the scene edge closest depth of each video frame; the depth of a first object is determined as the attention object depth of each video frame; the smaller value between the scene edge closest depth and the attention object depth serves as the zero parallax value; and a zero parallax value sequence composed of the zero parallax values of all the video frames can be obtained. According to the invention, the zero parallax value of each video frame can be automatically determined without manual setting, so that influence by factors such as insufficient experience is avoided, and workloads of technicians are reduced. Furthermore, on the premise that a window shielding problem does not occur, the zero parallax can approach an attention object as far as possible, so that the comfortableness can be guaranteed while the stereo perception can be improved as possible, and using effects of the determined zero parallax are guaranteed.

Description

Technical field [0001] The invention relates to the technical field of three-dimensional animation production, in particular to a method and system for determining parameters of an off-axis virtual camera. Background technique [0002] In recent years, with the popularity of 3D animation movies, 3D animation production technology has become a very important technology in movie production. [0003] The control of three-dimensional effects is particularly important in three-dimensional animation production. The zero parallax is the distance from the point where the left and right cameras cross and converge in the shooting direction to the midpoint of the baseline of the two cameras. The value of zero parallax has a greater impact on the stereo vision effect. After the zero parallax is determined, the off-axis virtual camera can be adjusted according to the zero parallax, so as to obtain a better stereo vision effect. The existing zero parallax is manually set, which is easily affec...

AI Technical Summary

Problems solved by technology

The existing zero parallax is set manually, which is easily affected by factors such as inexperience, and because zero parallax needs to be set for each video frame, the workload is huge
