Method and device for calibrating position and orientation of stage light fixture, electronic device, storage medium, and system

Abstract: a method for calibrating position and orientation of a stage light fixture includes acquiring light spot images and light fixture angle information when light beams of the stage light fixture respectively project on at least three different positions, and calculating first coordinates of a light beam center line projection point image in each of the light spot images in a camera coordinate system; deducing second coordinates of a light beam center line projection point on the stage in a stage coordinate system based on the first coordinates and information about internal parameters and a position and an orientation of a camera when the light spot images are acquired, and recording corresponding relationship between the second coordinates and the light fixture angle information; and determining a calibrated position and orientation of the target stage light fixture based on the second coordinates, the light fixture angle information and the corresponding relationship.
