摘要
The present invention discloses a method for acquiring a comfort degree of a motion-sensing binocular stereoscopic video. The method includes the following steps: S1. carrying out binocular parallax and movement speed analysis on an input binocular video, and calculating a binocular parallax d, a movement speed vxy in a visual plane direction and a movement speed vz in a depth direction of each pixel point in the video; S2. calculating a corresponding comfort degree value c according to the parameters (d, vxy, vz) of the pixel point; S3. calculating the comfort degree value of the entire frame according to the calculated comfort degree value of each pixel point; S4. calculating the comfort degree value of the entire video according to the comfort degree value of each frame. The comfort degree of the binocular stereoscopic video is calculated according to the steps in the present invention, so that influence of positive and negative depth ranges and object movement on the comfort degree can be well considered to obtain more accurate estimation of the comfort degree.
說明書
The present invention relates to the technical field of digital image processing, and particularly relates to a method for acquiring a comfort degree of a motion-sensing binocular stereoscopic video.
In the field of computer graphics, binocular stereoscopic images and videos are stereoscopic media formats which are widely studied and used. Binocular stereoscopic technology is used for achieving stereoscopic imaging by displaying different images to left and right eyes on a screen. Due to view angle-focusing mismatch in the imaging technology, when watching binocular stereoscopic videos, people will generate different degrees of discomfort. This discomfort is an important problem in the existing binocular stereoscopic technology, therefore, in order to prevent people from generating severe discomfort and even being incapable of performing binocular stereoscopic fusion when watching the binocular stereoscopic videos, how to measure the comfort degree of the binocular stereoscopic videos has important research and practical significance.
