The invention provides a switch rail abrasion detection method and device, and the method comprises a contour preprocessing step, a switch rail contour matching step and a switch rail abrasion calculation step, based on the mileage information of the target position and a key position switch rail profile line of a preset switch rail key position, a standard switch rail profile line of the target position is obtained through calculation and used for analysis and calculation, and therefore the problem that no corresponding drawing data exists at the target position between the two key positions of the switch rail is solved; furthermore, in the step of calculating the abrasion of the switch rail, the collected switch rail profile and the standard switch rail profile are matched with a preset standard full-section profile for calculation, a first deviation value and a second deviation value are obtained through calculation, and then the difference value between the first deviation value and the second deviation value is further calculated to serve as the abrasion loss of the switch rail. According to the method provided by the invention, the abrasion of each position of the switch rail can be calculated by adopting the same algorithm, so that the automatic and efficient abrasion detection of the whole switch rail section can be realized.
