Multi-visual-angle great-depth micro stereo visual-features fusion-measuring method

Abstract

The invention relates to a multi-visual-angle great-depth micro stereo visual-features fusion-measuring method, which comprises the following steps of: acquiring an original stereo-image pair through a barrel-type node structure by using a compound stereomicroscope visual system, and providing accurate matching-parallax data through the image registration and the stripe registration at different node positions on the same depth surface, the fusion of original composite-image sequences on different depth surfaces and the local matching of original images, so that high-precision three-dimensional figures can be reconstructed. The method can be used for solving the problems of sheltering in micro stereo measurement and precise visual measurement of large-scale microscopic objects, and technical bottlenecks existing in an existing stereomicroscope visual-measuring method are essentially overcome.

[0004] Aiming at the problems existing in the existing stereo microscope stereo vision measurement method, the present invention introduces a composite stereo microscope micro stereo vision measurement system that adds an auxiliary fringe projection system, a three-dimensional operating table, a rotary table and a lateral displacement table. The original stereo image pair is collected with a "barrel" node structure, and the original image sequence after the synthesis of the depth surface is output through the registration of the original image sequence at different node positions in the same depth surface, and the fusion of the original composite image sequence of different depth surfaces , output the original fused image after fusion, use this system to collect the fringe image, take the fringe edge pixel parallax as the main body, and the original image matching result in the local restricted area defined by the fringe edge as an auxiliary, and give the fringe composite disparity calculation result, its purpose It solves a large number of mismatching and mismatching phenomena caused by the existing stereoscopic vision measurement method of stereo microscope completely relying on the original image matching, improves the matching accuracy, and further solves the problems of occlusion and large depth measurement in this measurement method. Through fringe projection Realize the output of high-precision matching data
