The invention provides a track elastic strip displacement detection method and system based on target space position deviation. The method comprises the steps that a track brightness diagram is acquired through a laser contourgraph; performing data enhancement processing on the track brightness diagram, and detecting an elastic strip and a clamping plate in the track brightness diagram by using a target detection algorithm to obtain elastic strip and clamping plate detection data; processing according to the detection data of the elastic strip and the clamping plate to obtain coordinate information of the elastic strip and the clamping plate; according to the coordinate information of the elastic strip and the clamping plate, judging whether the elastic strip intersects with the clamping plate by using an intersection rule algorithm; if yes, elastic strip clamping plate intersection position information of each track brightness diagram is obtained through calculation; obtaining the minimum value h of the vertical coordinate difference value; the minimum value h is compared with a judgment threshold value Th, and whether the elastic strip shifts or not is judged; and carrying out elastic strip displacement drawing and information display. The technical problems that accuracy, reliability and detection efficiency of track elastic strip displacement detection are low, and the degree of dependence on railway track elastic strip displacement defect data is too high are solved.
