Abstract

The invention relates to a tracking method and apparatus. The method comprises the steps of obtaining point cloud data of multiple moving points of a current frame; determining at least one moving target based on a clustering algorithm according to the point cloud data of the plurality of moving points of the current frame; associating the point cloud data of a plurality of moving points of the current frame with the moving target based on an adaptive association gate and a nearest neighbor data algorithm to obtain associated data; and obtaining a moving track of the moving target according tothe associated data, thereby realizing tracking of the moving target. On the basis of obtaining the point cloud data of the moving target through radar signal processing, the tracking range is expanded, the moving target is detected and tracked, and the trajectory information of the moving target is obtained, so that the accuracy of the tracking algorithm is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a tracking method and device. Background technique [0002] With the continuous development of radar technology, its high sensitivity, no need for direct contact, and strong penetrability have attracted more and more attention from researchers. For example, terahertz radar imaging technology, mechanical vibration measurement, and human vital signs detection are used in airport security inspection instruments. With the development of artificial intelligence technology, the research on its combination with radar technology has become an important development direction. Using radar as a new input device, human-computer interaction is realized through intelligent algorithms. The radar technology is combined with the tracking algorithm to track the moving trajectory of the target in a specific area. The traditional tracking algorithm is used to track the target with low ...
