Abstract
The invention provides a device and method for calibrating a lens distortion center. The device includes a rotating frame, a first driving mechanism and a second driving mechanism. The first driving mechanism is connected with the rotating frame for driving the rotating frame to rotate. A calibration plate is arranged in the rotating frame and connected with the rotating frame through a rotating shaft. The second driving mechanism is connected with the calibration plate for driving the calibration plate to rotate relative to the rotating frame, and a lens placement platform is provided at a front end of the calibration plate. The device of the invention can adjust the relative position between the calibration plate and the lens through the cooperation of the first driving mechanism with the second driving mechanism, so that a lens can acquire different images to achieve calibration of lens distortion.
