Title:
CALIBRATION BOARD AND CALIBRATION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/226403
Kind Code:
A1
Abstract:
A calibration board (200a) and a calibration control device. A first calibration area (210a) and a second calibration area (220a) are presented on a panel of the calibration board (200a), wherein the first calibration area (210a) surrounds the outer side of the second calibration area (220a), and the first calibration area (210a) is used for identifying the shape of the calibration board on the basis of image collection. The first calibration area (210a) and the second calibration area (220a) are presented on the panel of the calibration board, which facilitates the accurate identification on an edge of the calibration board by a sensor, thereby achieving the accurate calibration of extrinsic parameters.
