Abstract

An embodiment of the invention provides a visual analysis based mountain railway side slope rockfall detecting method. The method mainly comprises collecting an image of a mountain railway, performing local linear detection and Hough exchange on the image and obtaining an image of a railway area; performing differential treatment and binaryzation segmentation process on the image of the railway image and obtaining a foreground target image; constructing a classifier based on a well-trained deep network and inputting the foreground target image into the classifier and judging whether the foreground target image belongs to the target image containing rockfall or not according to an output result of the classifier. According to the embodiment of the invention, the railway area is identified at first, then the image in the railway area is segmented, the foreground target is detected, and finally the target is classified through deep learning and interference targets are removed. The scheme provided by the embodiment of the invention has advantages of wide detection range, low cost and the like of a video analysis method. At the same time, the rockfall image detection accuracy is improved.

Description

technical field

[0001] The invention relates to the field of railway foreign matter invasion and limitation, in particular to a method for detecting rockfall on mountainous railway slopes based on visual analysis. Background technique

[0002] In mountainous road sections where geological disasters occur frequently, rockfall from slopes often invades the railway boundary, which seriously endangers the safe operation of trains. Rockfall on slopes is characterized by suddenness, irregularity, and unpredictability. If the driver only relies on the driver to visually detect foreign objects and then take braking measures during the operation of the train, accidents will not be effectively avoided, and traffic safety will be seriously threatened.

[0003] Intrusion of foreign objects including rockfall on slopes poses a serious threat to the safe operation of railways. Scholars at home and abroad have gradually realized the importance of intrusion detection and carried out related...
