REBAR SPACING MEASUREMENT METHOD AND SYSTEM BASED ON BINOCULAR VISION

A rebar spacing measurement method and system based on binocular vision. The method comprises: acquiring a plurality of images of bound rebars at different angles, and extracting edge lines from each image; according to the edge lines in each image, obtaining intersection points of the rebars in each image; performing three-dimensional reconstruction according to the intersection points of the rebars in each image, so as to obtain three-dimensional coordinates of the intersection points of the rebars; and traversing the three-dimensional coordinates of the intersection points of the rebars, so as to obtain the spacing between the rebars. The rebar spacing measurement method and system based on binocular vision solve the problem of it not being possible for image technology to distinguish intersection points of bound rebars on different spatial planes, and thus needing to place a calibration object on the surface of a rebar to be tested. The technique is easily used; high precision, a high speed and strong app
