Calibration method, device and equipment of vehicle-mounted surround view equipment and medium

The invention provides a calibration method, device, equipment and medium for vehicle-mounted all-round looking equipment, and the calibration method comprises the steps: obtaining preset world coordinate data and position prior data of a calibration board, the world coordinate data representing a coordinate set of all angular points in the calibration board with a vehicle body as a reference system; identifying an identifiable square block in the calibration plate through a camera, generating a position mask of the identifiable square block, and generating pixel position data of a corner point corresponding to the identifiable square block; performing comparison processing on the position mask and the position prior data to generate pixel position data of all angular points in the calibration plate according to the pixel position data of the corresponding angular points of the recognizable square block; and calculating and generating external parameter data of the camera according to the pixel position data
