The invention discloses a track abrasion measuring method and device, a medium and equipment. The method comprises the following steps: acquiring point cloud data of a track to be measured and point cloud data of a standard track; the point cloud data of the track to be measured comprises first contour point cloud data and second contour point cloud data; inputting the contour point cloud data into a pre-trained Point Net + + network to obtain rail waist point cloud data; selecting a standard point from the point cloud data of the standard track, and performing point cloud registration by using an ICP algorithm to obtain a first corresponding point and a second corresponding point of the standard point; creating a projection plane based on the first corresponding point and the second corresponding point, and projecting the contour point cloud data to the projection plane to obtain point cloud data of a projection track; and performing ICP algorithm registration on the point cloud data of the standard track and the point cloud data of the projection track to obtain a measurement result of abrasion of the track to be measured. According to the invention, the measured value of track abrasion can be obtained, and the stability and accuracy of track measurement are improved.
