Problems solved by technology
The source 2D video stream of the 3D video generated by these two methods may not be synchronized, or the frame stream of the camcorder is unstable, or the time of the video frame does not match when the two video streams are edited separately.
These issues result in poor 3D video
These problems are caused by the inability to generate accurate 3D video depth maps

The invention relates to a method for creating an accurate depth map for a three-dimensional video, belongs to the field of three-dimensional image video processing, and particularly relates to a method for creating an accurate depth map for the three-dimensional video by processing video frames. A two-dimensional and / or three-dimensional image is obtained; an absolute time mark is added to each video frame of the two-dimensional and / or three-dimensional video; the two-dimensional video added with the absolute time mark is converted into the three-dimensional video; an accurate depth map is determined for the three-dimensional video added with the time mark according to the time mark; and the three-dimensional video is edited into a partial or complete three-dimensional video. The invention provides a method for creating the accurate depth map for the three-dimensional video by processing the video frames; thus, the three-dimensional quality of the processed video is better, and the experience effect of users is improved.
Description
technical field [0001] The invention belongs to the field of three-dimensional image and video processing, and in particular relates to a method for creating an accurate depth map of a three-dimensional video by processing video frames. Background technique [0002] With the development of technology and the popularization of 3D video, people have higher and higher requirements for 3D video quality, especially in the case of different shooting sources, how to display clear 3D video to users has become the focus of research. [0003] The 3D video captured by the stereo camera is recorded as two 2D videos by two image sensors; the 2D video captured by a single or multiple monoscopic cameras is converted into a 3D video. The source 2D video stream of the 3D video produced by these two methods may not be synchronized, or the frame stream of the camcorder is unstable, or the timing of the video frame does not match when the two video streams are edited separately. These issues l...
