Embodiment Construction

[0015] The present invention will be described in detail below in combination with specific embodiments.

[0016] The invention provides an image recognition method for the minimum radius of curvature of a rail, comprising the following steps,

[0017] Step 1, obtain the target image through the camera device; by installing the camera device in front of the train, when the train is running, the image information of the railroad track in front of the train can be obtained,

[0018] Step 2, the target image obtained in step 1 is subjected to histogram equalization preprocessing; the gray histogram of the target image is changed from a relatively concentrated gray scale interval to a uniform distribution in the entire gray scale range, and the The image is stretched non-linearly, and the pixel values ​​of the image are redistributed so that the number of pixels in a certain gray range is approximately the same.

[0019] Step 3: Construct a region growth model based on the balanc...

Abstract

The invention discloses an image identification method of the minimal radius of curvature of a rail. The image identification method comprises steps of obtaining a target image; performing histogram equalization on the target image; constructing a region growth model; and performing curve fitting. Thus, identification of the minimal radius of curvature of the rail by use of image processing is achieved; burdens of manual watching work are removed; potential safety hazards to train driving caused by fatigues of a driver are reduced; and a pre-warning function is achieved for safe running of the train.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to an image recognition method for the minimum curvature radius of a rail. Background technique [0002] During the operation of the railway train, the driver usually gives an early warning to the situation ahead by looking out, so long-term observation will cause fatigue to people. Thereby, due to personnel mistakes such as dispatching and drivers, the train will go out of overspeed operation on the rail with the smallest radius of curvature, which will cause great hidden dangers to the safe operation of the train. Therefore, need a kind of objective, non-artificial reminding equipment to help train driver carry out early warning. [0003] Digital image processing technology has achieved rapid development because of its high processing precision, rich content, complex calculations and good flexibility. Therefore, it is an effective way to solve the rail curv...
