Three-dimensional analysis and processing method of target object stereo vision based on hierarchical sampling

Abstract

The invention provides a target object stereoscopic vision three-dimensional analysis and processing method based on hierarchical sampling. According to the target object stereoscopic vision three-dimensional analysis and processing method based on hierarchical sampling, the hierarchical sampling mode is adopted, and in the process of the first time of binocular digital image acquisition, the widest shooting view angle range is ensured; the mode that sampling is carried out on the situation of K times of pixels is adopted, so that the amount of data operation for target object recognition carried out on a large-view-angle left view image and a large-view-angle right view image is greatly reduced; in the process of the second time of binocular digital image acquisition, similarly, under the conditions of the widest shooting view angle range and the highest resolution ratio, a target object serves as the center, point-by-point sampling is carried out according to the preset resolution ratio range, the amount of data operation in the follow-up process of stereoscopic vision three-dimensional analysis carried out on the target object can be reduced, real-time performance can be improved, the imaging definition of the target object is ensured, and therefore the problem that in the process of application of stereoscopic vision three-dimensional analysis carried out on the target object on the basis of binocular stereoscopic imaging, consideration cannot be given to real-time performance, the view angle range and the imaging definition at the same time is effectively solved.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to a three-dimensional analysis and processing method for stereo vision of a target object based on hierarchical sampling. Background technique [0002] Binocular stereo vision technology is an important branch in the field of image processing technology. It usually uses binocular cameras to directly simulate the way human eyes process scenes, and collects left and right images from different viewpoints to determine the three-dimensional structure of the monitored scene. Unlike general photography systems that can only record 3D scenes in two-dimensional form and lose a lot of information, binocular stereo vision systems can obtain 3D data of scenes, so they are widely used in robot vision, aerial surveying and mapping, military applications, medical diagnosis and industry. It has been widely used in detection. [0003] In industrial product geometric parameter det...
