Method for detecting moving target based on millimeter wave radar and video data fusion

Abstract

The invention discloses a method for detecting a moving target based on millimeter wave radar and video data fusion, which comprises steps of performing all-weather perimeter intruded target detectionby using a high-definition camera and a millimeter wave radar, and uploading the data acquired by the high-definition camera and the millimeter wave radar to a server in real time; then performing deep recognition based on an algorithm to detect an intruded target. By combining the millimeter wave radar and the high-definition camera, the method solves the problem that an existing perimeter security protection system has a low target recognition rate and poor adaptability to special environment, has high target detection accuracy and reliability, adapts to special environments such as cloud,rain and snow, reduces deployment and maintenance cost, and more importantly, solve the urgent problem that a current tracking target cannot be visualized.

Description

technical field [0001] The invention relates to a method for detecting a moving target, in particular to a method for detecting a moving target based on the fusion of millimeter wave radar and video data. Background technique [0002] Perimeter security refers to the boundary between the unit and the external environment, adding an isolation measure to block the intrusion of all unauthorized people and animals. When the level of technology is not sufficiently developed, most places are only at the border Set up barriers such as iron fences, fence nets, walls, etc. to prevent illegal intrusion and various damages, but with the advancement and promotion of technology, perimeter security has been given new meaning. [0003] In the 1990s, due to its advantage of being invisible to the detection medium, infrared radiation became the mainstream product for peripheral intrusion detection in the market at that time. However, the energy of the infrared light source is not concentrate...

Among them, the most widely used anti-theft alarm system for the perimeter of the electronic fence is the tension fence. The tension fence is composed of many complex equipment such as front-end detectors, intrusion detection hosts, intelligent control terminals, and security management platforms. For perimeter security, the installation base requirements are high and the maintenance cost is high

Vibrating optical fiber is used for perimeter security. The system equipment is simple in structure and has strong real-time performance. However, according to the principle of vibrating optical fiber detection of targets, there are disadvantages such as non-invasive vibration that can easily cause false alarms and be easily overturned.

The microwave radar electronic wall perimeter security system is composed of a pair of radar transmitter and receiver equipment. The two equipment are installed at a certain distance, which is the protection area. The advantage of this equipment is that it has high protection sensitivity and can effectively avoid small animals. However, the disadvantage is that its protection area can only be a straight line area, which cannot adapt to terrain changes, is expensive, and the equipment is exposed to the outside and is easy to be damaged. There is a protective blind area at the proximal end of the equipment.
