High-speed rail perimeter intrusion monitoring device and method based on millimeter-wave radar and camera

Abstract

The invention discloses a high-speed rail perimeter intrusion monitoring device and method based on a millimeter-wave radar and a camera, which belongs to the technical field of high-speed rail perimeter security, and is characterized in that the perception module includes an imaging millimeter-wave radar and a camera; The point cloud data and image data, first preprocessing the point cloud data and foreign object feature recognition, image data preprocessing and foreign object feature recognition; then preliminary intrusion foreign object judgment and identification, and finally point cloud data and image data fusion processing, judging and identifying the intruding foreign object again; the responding part receives the output result of the information processing part, and makes an action of whether to alarm and display information according to the result. The invention fuses imaging millimeter-wave radar and ultra-high-definition camera sensing information, thereby overcoming the limitation of a single monitoring method, and can realize rapid and accurate identification of intruding pedestrians, animals, falling rocks and other foreign objects in complex environments, and automatically issue alarm information.

Description

technical field [0001] The invention belongs to the technical field of high-speed rail perimeter security, and in particular relates to a high-speed rail perimeter intrusion monitoring device and method based on a millimeter-wave radar and a camera. Background technique [0002] At present, the mileage of high-speed railways that have been put into operation in my country exceeds 40,000 kilometers. It is the country with the longest operating mileage, the highest operating speed and the most complex operating scenarios in the world. With the rapid increase in the mileage of high-speed railways, the intrusion of the perimeter of high-speed railways has become an important problem that needs to be solved urgently in railway safety. There are three main types of potential threats in the perimeter of high-speed rail: illegal invasion, man-made damage and natural damage. Due to the large number of important equipment in the high-speed railway station and the area along the line,...

Problems solved by technology

However, from the perspective of testing and application results, a single perimeter intrusion detection method has disadvantages, such as vibrating optical fiber, leaking cable, light wave through-ray detection, multi-dimensional three-screen vibration detection technology, etc. have poor anti-interference ability and high false alarm rate The defects of pulse electronic fence, tension fence, microwave array, laser radar, etc. have the disadvantage of high construction and operation costs, and infrared detection, video monitoring, etc. have the disadvantage of poor environmental adaptability

None of these methods can be applied to the complex environment along the high-speed rail, and can meet the application requirements of "no false positives, low false positives, and low cost" for high-speed rail perimeter intrusion security.
