The invention provides an initiative-view-angle binocular vision ranging system which comprises an image acquisition unit, a target region intercepting unit, a matching unit, a view deviation calculation unit and a distance measurement unit, wherein the image acquisition unit is used for acquiring binocular images through a detection camera; the target region intercepting unit is used for intercepting target regions from the binocular images, and the intercepted target regions comprise acquired template images and detected region images; the matching unit is used for matching optimal matched target images through a fast matching algorithm; the view deviation calculation unit is used for acquiring view deviation between the binocular images according to the template images, the optimal matched target images, as well as coordinate corresponding relation among the template images, the optimal matched target images and the binocular images; the distance measurement unit is used for establishing an initiative-view-angle ranging model according to the view deviation, the imaging point distance of a binocular camera and estimated first and second parameters, and measuring the detected target distance according to the initiative-view-angle ranging model.
Description
technical field [0001] The invention relates to the technical field of remote distance measurement, in particular to an active viewing angle binocular distance measurement system and method. Background technique [0002] The commonly used ranging methods in long-distance ranging are laser ranging or radio ranging, but both laser ranging and radio are active ranging methods, which are easy to be detected and counteracted. [0003] In passive vision distance measurement technology, the binocular distance measurement method is widely used. The existing distance measurement methods are more widely used as the angle of view distance measurement method and the parallel optical axis distance measurement method. The former has a complex structure and a large volume, and the latter measures distance. restricted. Contents of the invention [0004] In order to solve the disadvantages of complex structure, large volume and limited measurement distance of the parallel optical axis ran...
