Calculation method of deflection angle between camera and carrying platform, calibration plate and detection device

The invention provides a calculation method for a deflection angle between a camera and a carrying table, a calibration plate and a detection device, and the method comprises the steps: controlling the camera and the carrying table to carry out the relative translational motion along an X-axis direction, respectively obtaining images of two opposite ends of the calibration plate disposed on the carrying table, and obtaining a first calibration image and a second calibration image, the first calibration image and the second calibration image respectively comprise a plurality of mark symbols located at the two ends of the calibration plate; detecting and calculating deflection angles of the first calibration image and the second calibration image relative to the X-axis direction based on the key points of the mark symbols in the first calibration image and the second calibration image to obtain a first deflection angle theta1 and a second deflection angle theta2; and the first deflection angle and the second de
