| description | The invention provides a laser-assisted calibration device and a use method of the device, and the calibration method comprises the steps: enabling three lasers to irradiate a measurement surface by adjusting the laser angle, collecting a reference image, storing the reference image as a gray image, removing a calibration object, placing the calibration object on a multi-dimensional translation stage, reading the reference image, setting the reference image as a dark channel, and carrying out the calibration. A current gray level image is collected in real time and set as a bright color channel, a dark color channel image and the bright color channel image are synthesized in real time to form an image, a calibration plate is placed on a translation table to collect the image, angular point information of the calibration plate is extracted, internal and external parameters of a camera under an ideal condition are calculated finally, and a distortion coefficient of radial distortion is obtained by using a least |
