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, and belongs to the technical field of high-speed rail perimeter security, and the device is characterized in that a sensing module comprises an imaging millimeter-wave radar and a camera; the information processing part receives the point cloud data and the image data of the sensing part, firstly performs preprocessing and foreign matter feature recognition on the point cloud data, and performs preprocessing and foreign matter feature recognition on the image data; performing preliminary invasion foreign matter determination and identification, performing fusion processing on the point cloud data and the image data, and performing determination and identification on the invasion foreign matter again; and the response part receives an output result of the information processing part and makes actions of whether to give an alarm or not and displaying information according to the result. According to the invention, sensing information of the imaging millimeter wave radar and the ultra-high-definition camera is fused, so that limitation of a single monitoring means is overcome, rapid and accurate identification of foreign matters such as invading pedestrians, animals and rockfall in a complex environment can be realized, and alarm information can be automatically issued.

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 high-speed railway mileage that has been put into operation in my country exceeds 40,000 kilometers. It is the country with the longest high-speed railway operating mileage, the highest operating speed and the most complex operating scenarios in the world. With the rapid increase of high-speed railway mileage, high-speed railway perimeter intrusion has become an important problem that urgently needs to be solved in railway safety. There are three main types of potential threats in the perimeter of high-speed rail: illegal intrusion, man-made destruction and natural destruction. Due to the large number of important equipment in the high-speed railway station and the area along the lin...

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.
