Calibration method and device of contourgraph camera and electronic equipment

The embodiment of the invention provides a contourgraph camera calibration method and device and electronic equipment, and the method specifically comprises the steps: obtaining three-dimensional point cloud data obtained through the collection of a calibration block by a contourgraph camera, determining a model constraint condition of each surface for each surface of the calibration block, and determining local point cloud data belonging to each surface of the calibration block from the three-dimensional point cloud data, determining an external parameter which enables the local point cloud data of each surface to be matched with a model constraint condition of each surface as a target external parameter of the contourgraph camera, and calibrating the contourgraph camera. Therefore, according to the embodiment of the invention, the contourgraph camera can be calibrated based on the surface model constraint condition of the calibration block by means of the calibration block with a simple structure, the calib
