Foreign matter invading detecting method and foreign matter invading detecting device

Abstract

The invention provides a foreign matter invading detecting method and a foreign matter invading detecting device. The foreign matter invading detecting method comprises the following steps that infrared images within the monitoring scope are acquired by utilizing an infrared camera and are transmitted to an image collecting and processing system; whether a suspected foreign matter appears in the monitoring scope or not is determined by the image collecting and processing system according to the infrared images; when the suspected foreign matter appears, the laser light source and a visible light camera are focused on the suspected foreign matter within the monitoring scope, and filling light of laser light is conducted on the suspected foreign matter by utilizing the laser light resource; visible light images of the suspected foreign matter are acquired and transmitted to the image collecting and processing system; image registration and image fusion are conducted on the visible light images and images of the suspected foreign matter area in the infrared images by the image collecting and processing system; and information of the suspected foreign matter is provided by utilizing the fused images, and feature extraction and classification are conducted on the suspected foreign matter by utilizing the information of the suspected foreign matter, automatic identification and alarming for the suspected foreign matter are realized, and abundant and complete image information can be acquired in the time of dark light, dark skies and low visibility.

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 the scale 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 operation is also increasing. During the long-term service of 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 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 princip...
