Tracking method, tracking system, and tracking device for rail profile

Abstract

The invention discloses a tracking method, a tracking system, and a tracking device for rail profile. The method comprises: obtaining at least one frame of rail profile image, wherein each frame of the rail profile image is an image obtained by fusing images in multiple directions of the collected rail according to a frame in the process of measuring the rail profile by using the structured light;identifying the light strip type of the laser stripe in each frame of the rail profile image based on the deep learning profile identification model; tracking the position of the target stripe in therail profile image of the current frame based on the spatiotemporal context visual tracking algorithm in a case that the light strip type of the laser stripe in the rail profile image of the currentframe is the same as the previous frame; or tracking the position of the target stripe in the ail profile image of the current frame based on the template matching algorithm in a case that the light strip type of the laser stripe in the rail profile image of the current frame is different from the previous frame. According to the tracking method, the tracking system, and the tracking device for rail profile, the technical effect of the real-time detection of the rail profile under the high-speed dynamic driving environment is realized.

Description

technical field [0001] The invention relates to the field of computer vision detection, in particular to a tracking method, system and device for a rail profile. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The role of the rails is to support and guide the wheels of the rolling stock, directly absorb the forces from the wheels and transmit them to the sleepers, and at the same time provide the contact surface of least resistance for the rolling of the wheels. The process of the train running on the track day and night to complete the transportation task is also the process of the friction between the track and the locomotive wheels. Therefore, the analysis of the profile shape of the rail, especially the profile of the rail head is an important basis for detecting rail fau...
