The invention discloses a stereoscopic video visual comfort evaluation method based on region segmentation and belongs to the technical field of three-dimensional picture evaluation. The method comprises the steps of self-adaptively extracting motion areas in stereo video sequences and significant areas in background parts; combining depth sensing theory and space combination technology to conduct modeling on the characteristic quantity of visual comfort level; utilizing the linear regression method and combining the logic relationship between human being subjective evaluation testing results and the parallax depth to select undetermined coefficient and feature weighting value conforming to the human being subjective evaluation results and realize evaluation of stereoscopic video comfort adaptiveness. The method demarcates projection equipment and experimental conditions, respectively presets weight on a background part and a motion target in a significant region to realize optimization of evaluation results of comfort level, builds a stereo image quality objective evaluation model conforming to human subjective perception results, and has an immeasurable significant function in quickening the development of a stereo video system.
