Abstract:

In order to comprehensively improve the accuracy of real-time tracking results for mixed moving targets， a real-time tracking method for mixed moving targets based on GPS-UWB combined positioning technology is proposed. Establish a three-dimensional surface information reconstruction model for mixed motion target images， and use multidimensional pixel reconstruction methods to perform information fusion and motion feature point calibration for mixed motion targets， analyzing the differential feature vectors of different target points. At the same time， the GPS-UWB combined positioning technology is introduced to optimize the real-time positioning of mixed moving target points， ultimately achieving real-time tracking of mixed moving targets. The experimental test results show that the proposed method can obtain real-time tracking results of mixed moving targets with higher stability and smaller errors.

Key words: GPS-UWB combined positioning technology, mixed motion targets, real time tracking
