Abstract

The invention discloses a method for tracking a moving object based on a stereoscopic vision measuring technology. The method comprises configuring a measuring station system which comprises a plurality of measuring stations; performing calibration on the measuring station system within a large field of view; utilizing the measuring stations in the calibrated measuring station system to obtain theposition of an associated stereoscopic target, and calculating and obtaining a conversion relationship between a coordinate system in which each measuring station is located and a world coordinate system in which a photoelectric tracker is located; and using three-dimensional data of the tracked moving object under each measuring station coordinate system to convert the three-dimensional data ofthe moving object tracked by different measuring stations under the world coordinate system. In the method according to the technical scheme, against the situation that the prior art cannot satisfy the requirement of the tracking process of the long-track moving object with a large field of view, the large-field-of-view binocular stereo vision system calibration method with high precision and highflexibility is adopted to accurately track the large-range long-track moving object, and high measurement accuracy is ensured.

Description

technical field [0001] The invention belongs to the technical field of stereo vision measurement, and in particular relates to a moving object tracking method based on the stereo vision measurement technology. Background technique [0002] In recent years, computer vision has become a research hotspot in the computer field, and moving object tracking, which is an important part of computer vision, has attracted more and more attention. Its application fields have been extended to video surveillance systems, vehicle tracking, abnormal behavior detection and alarm. , image compression and coding techniques, etc. Moving object tracking methods mainly include Kalman filter, Mean-shift, Camshift algorithm, particle filter, Snake model, etc. Moving object tracking has been gradually applied to our real life, and it is one of the key technologies to promote the process of intelligence. [0003] The moving object tracking method is a method for accurately tracking the movement of ...
