Title:
MULTI-VIEW CAMERA CALIBRATION DEVICE AND METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/166113
Kind Code:
A1
Abstract:
Embodiments of the present application disclose a multi-view camera calibration device and method, and a storage medium. The device comprises: a calibration board; a moving module which is provided below the calibration board and configured to switch a spatial position state of the calibration board in a photographing range of a plurality of cameras; and a control module which is connected to the moving module and the plurality of cameras and configured to switch the spatial position state of the calibration board by means of the moving module and control the plurality of cameras to photograph the calibration board while the moving module completes switching of the spatial position state of the calibration board, such that calibration images of the complete calibration board in the corresponding spatial position state are simultaneously captured by at least two cameras. The steps of switching the spatial position state of the calibration board by means of the moving module and controlling the plurality of cameras to photograph the calibration board while the moving module completes switching of the spatial position state of the calibration board are repeated; under the condition that the number of the calibration images simultaneously captured by any two cameras reaches a target number, the any two cameras are classified into one group until the number of the calibration images simultaneously captured by any two cameras in each group of cameras among all the cameras reaches the target number; and a calibration result of each group of cameras is determined according to the calibration images captured by each group of cameras among all the cameras, such that calibration of all the cameras is completed.
