Foreign matter intrusion detection method and foreign matter intrusion detection device

Abstract

A foreign object intrusion detection method and a foreign object intrusion detection device, the method comprising the steps of: using an infrared camera to acquire an infrared image within a monitoring range and transmitting it to an image acquisition and processing system; Whether there is a suspected foreign object within the monitoring range; when there is a suspected foreign object, focus the laser light source and the visible light camera on the suspected foreign object within the monitoring range and use the laser light source to perform laser supplementary light on the suspected foreign object; obtain the visible light image of the suspected foreign object and The image is transmitted to the image acquisition and processing system; the image acquisition and processing system performs image registration and fusion on the suspected foreign object area image in the visible light image and the infrared image; uses the fused image to provide the suspected foreign object information, and uses the suspected foreign object information to perform feature extraction and analysis of the suspected foreign object. Classification, to realize automatic identification and alarm of suspected foreign objects, and to obtain rich and complete image information when the light is dark, the smoke is dense, and the visibility is low.

Description

technical field [0001] The invention relates to the technical field of railway operation safety detection, in particular to a foreign object intrusion detection method and a foreign object intrusion detection device. Background technique [0002] With the continuous expansion of my country's high-speed railway network and the rapid development of high-speed train equipment manufacturing technology, attention to the safety of high-speed railway operations is also increasing. During the long-term service of the high-speed railway infrastructure, some problems worthy of attention have been exposed. Any personnel or foreign objects that intrude into the railway boundary during operation will seriously threaten the safe operation of the high-speed railway and cause serious railway accidents. Therefore, accurate and timely detection of foreign objects intruding into the track boundary is the key to ensuring the safe operation of rail transit. According to the detection principle, ...

Problems solved by technology

This method can achieve good results under experimental conditions, but because the visible light image is affected by the ambient illuminance, the work effect at night is poor, which will affect the accuracy and reliability of these detection systems, and the above system does not take into account the system in Adaptability issues in environments with poor line of sight at night
