Objective evaluation method of long-distance parallel shooting quality of stereo camera

Abstract

The invention belongs to the technical field of three-dimensional image collection, and relates to an objective evaluation method of the long-distance parallel shooting quality of a stereo camera. The objective evaluation method comprises the steps that a subjective evaluation value is set to be MOS, an evaluation standard of the long-distance parallel shooting quality of the stereo camera are determined and the relationship between the evaluation standard and the subjective evaluation value MOS is established; the corresponding relationship between the range of the value of an objective evaluation index d / h and a corresponding objective evaluation value of the stereo image quality, the corresponding relationship between the range of the value of an objective evaluation index xi and the corresponding objective evaluation value of the stereo image quality, the corresponding relationship between the range of the value of an objective evaluation index k related to the visual-sensitive angle theta of the stereo camera and the corresponding objective evaluation value of the stereo image quality and the corresponding relationship between the range of the value of a shape distortion mu related to the visual-sensitive angle theta and the corresponding objective evaluation value of the stereo image quality are determined respectively; the stereo camera is used for shooting a stereo image pair on the conditions of long-distance and parallel arrangement; the objective evaluation indexes d / h, xi, k and mu of stereo images are calculated, objective evaluation is conducted on the stereo camera, and an objective evaluation value Q of the stereo image pair is obtained; the objective evaluation value Q and the subjective evaluation value MOS are compared, and an objective evaluation result of the shot stereo image pair is obtained. The objective evaluation method can effectively evaluate the quality of the stereo images shot by stereo camera in a long-distance and parallel mode.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional image acquisition, and in particular relates to an objective evaluation method for long-distance parallel shooting quality of a stereo camera. Background technique [0002] In recent years, more and more stereoscopic images have emerged, which have brought unprecedented visual impact to people, and the reproduction of the real world has become a reality. With the development of stereoscopic technology, the processing technology of stereoscopic (3D) images is becoming more and more mature, and the sources of stereoscopic images in various countries in the world are increasing day by day, satisfying people's desire to see 3D images on the screen. Due to the inadequacy of stereoscopic image processing technology or display technology, people will experience discomfort symptoms such as dizziness, nausea, and decreased body balance when watching certain film sources. Therefore, researchers ha...
