Problems solved by technology
[0003] However, since multi-target tracking is much more complicated than single-target tracking, it is prone to crossover in the process of tracking multiple targets, which may lead to inaccurate identification and tracking of targets, loss of tracking targets or tracking of wrong targets, and Target tracking devices based on infrared sensors are susceptible to interference from rainy weather, smog, etc., and the emitter must be aimed at the target. It is difficult to apply in real life scenarios. Radar sensors have wide emission angles and strong interference capabilities, which can solve this problem

The present invention provides a radar sensor-based multi-target tracking device and method, including: a radar module, used to lock multiple targets in the preset area, and transmit radar signals to the preset area based on the radar sensor, and receive The echo signals reflected by multiple targets in the preset area; the processing module determines the moving distance and moving speed of each target according to the radar signals and the echo signals, and according to the moving distance and moving speed , determine the movement trajectory of the corresponding target, and transmit it to the display module for display. Through the radar sensor detection and multi-target tracking method, the tracking of multiple targets is realized, and the efficiency and accuracy of multi-target tracking are improved.
Description
technical field [0001] The invention relates to the technical field of target tracking, in particular to a radar sensor-based multi-target tracking device and method. Background technique [0002] Target tracking is one of the core issues of machine vision. It is a high-tech fusion of advanced achievements in different fields such as image processing, pattern recognition, artificial intelligence and automatic control. It plays an important role in many fields such as military guidance, vehicle tracking, and product inspection. Practical value and development prospects. [0003] However, since multi-target tracking is much more complicated than single-target tracking, it is prone to crossover in the process of tracking multiple targets, which may lead to inaccurate identification and tracking of targets, loss of tracking targets or tracking of wrong targets, and Target tracking devices based on infrared sensors are susceptible to interference from rainy weather, smog, etc., ...
