Abstract

The present application is applicable to the technical field of optical motion capture, and provides a multi-camera system calibration method, a multi-camera system and a terminal device. The method comprises: acquiring a moving path, and controlling a robot to move inside a collection area of the multi-camera system according to the moving path; collecting an image sequence of a target object installed on the robot through the multi-camera system; and generating a position and a direction of each camera in the multi-camera system according to the image sequence of the target object collectedby the multi-camera system. According to the method provided by the present application, the position and shooting direction of each camera in a multi-camera system can be efficiently and accurately calibrated.

Description

technical field [0001] The present application belongs to the technical field of optical motion capture, and in particular relates to a multi-camera system calibration method, multi-camera system and terminal equipment. Background technique [0002] The multi-camera system is based on the principle of computer vision, which combines multiple cameras, light sources, storage devices, etc., and is often used in 3D reconstruction, motion capture, and multi-view video. For example, optical motion capture is based on the principle of computer vision, and multiple high-speed cameras monitor and track target feature points from different angles to perform motion capture. [0003] However, in order to realize the motion capture of target feature points or target objects, it is necessary to obtain the precise position of each camera participating in the shooting in the multi-camera system. At present, manual calibration is usually used to calibrate each camera in the multi-camera syst...
