Two-dimensional displacement sensing method for tile paving

The invention relates to a two-dimensional displacement sensing method for tile paving, and relates to the technical field of image recognition, and the method comprises the following steps: placing a laser level meter at a designated position, projecting a horizontal laser emission unit and a vertical laser emission unit to a reflector, and turning on an industrial camera to collect an image at a high frame rate; carrying out sensitivity enhancement on the acquired image, then carrying out feature point identification, and obtaining a central point of a laser ray; fitting a plurality of straight lines, selecting two laser lines, converting points on the image into space coordinates by adopting an affine transformation matrix, and calculating position deviation; and the deviation value is fed back to the controller, the controller controls the mechanical arm to move the tail end support so that adjustment can be completed within +/-0.1 mm near the center line of laser projected by the laser gradienter on the
