Method for tracking moving object based on stereoscopic vision measuring technology

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.
