Evaluation of depth perception based on binocular stereo vision

摘要

With the development of image and video technology based on binocular stereo vision, more and more researches have focused on perception effects and influence factors of stereoscopic 3D (S3D) images. Up to now, investigation of factor analysis and evaluation for the depth perception of S3D image is still rare. Therefore, in this paper, we designed three subjective experiments with the content-based factors of luminance, contrast and subject size for depth perception assessment of S3D image sequences generated by computer, under different combination conditions of parallax and shape. Experiments results demonstrated that the luminance and size of main object exhibited remarkable impact on space perception and volume perception, while the content feature of contrast only has clear influence on the volume perception. Our studies have practical significance and reference value to improve viewing experience and relative objective models for the S3D images and videos.
