Target detection and tracking system and method

Abstract

The invention provides a target detection and tracking system and method, the system comprises a millimeter-wave radar group and a back-end control module, the millimeter-wave radar group comprises a plurality of millimeter-wave radars, and the back-end control module is used for establishing a holographic coordinate system according to an application scene and carrying out coordinate system parameter calibration on the plurality of millimeter-wave radars according to the holographic coordinate system, sending the coordinate system parameters of the plurality of millimeter wave radars to the corresponding millimeter wave radars; the plurality of millimeter-wave radars are respectively used for transmitting electromagnetic wave signals to an application scene, receiving reflected millimeter-wave echo signals and acquiring target characteristic information of a target object according to the electromagnetic wave signals, the millimeter-wave echo signals and coordinate system parameters of the plurality of millimeter-wave radars, wherein the rear-end control module is further used for processing the target feature information through the target detection model so as to perform real-time tracking and statistics on the target object. Therefore, the target object can be accurately detected and tracked, and the privacy potential safety hazard can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a target detection and tracking system and a target detection and tracking method. Background technique [0002] With the development of smart cities, the demand for complex scenarios is becoming more and more urgent, such as: monitoring the situation of personnel in closed environments such as entire office buildings, hotels, supermarkets, and cinemas, and establishing a distribution system for personnel in the entire building. The holographic scene can understand the distribution of personnel statistics in real time. At the same time, it can control the power supply, lighting, air conditioning and other equipment of the building; the monitoring of personnel distribution statistics in semi-closed environments such as campuses is conducive to the management of students; the monitoring of personnel density statistics of tourist attractions, analysis of personnel density an...
