The invention discloses a steel rail wear position identification method and a device, and a computer readable storage medium. The method comprises the steps of acquiring a steel rail long image containing a wear position; obtaining a steel rail area length image according to the obtained steel rail length image, and obtaining a series of steel rail area image frames according to the steel rail area length image; judging whether pixels in the steel rail region image frame are wear points by utilizing a pre-established Gaussian mixture model; performing the following operations on each pixel point in the steel rail region long image: obtaining the number of steel rail region image frames of which the pixel points are judged as wear points; when the obtained number is greater than a preset number, determining that the pixel point is a wear point; and determining the wear position of the steel rail area according to the determined wear point. The Gaussian mixture model is used for judgingwhether the pixels in all the steel rail area image frames are the abrasion points, and then the abrasion positions are determined according to the abrasion points, so that automatic identification of the abrasion positions on the surface of the steel rail is realized, the labor cost is saved, and the identification efficiency is improved.
Description
technical field [0001] This article relates to image processing technology, in particular to a method, device and computer-readable storage medium for identifying rail wear positions. Background technique [0002] As modern trains travel faster and faster, the safety requirements for railways also increase. However, due to problems such as corrosion and excessive transport loads, the surface of the rails will be worn to varying degrees. If they are not discovered and maintained in time, it is very likely to cause serious train accidents. [0003] In related technologies, the identification of rail surface wear mainly relies on manual inspection and visual inspection. [0004] However, this method consumes a lot of labor costs, and the recognition efficiency is low. Contents of the invention [0005] The present application provides a method, a device, and a computer-readable storage medium for identifying rail wear positions, which can realize automatic identification of...
