Document Type and Number:
WIPO Patent Application WO/2024/011764
Kind Code:
A1
Abstract:
A calibration parameter determination method and apparatus, a hybrid calibration board, a device, and a medium. The method comprises: acquiring a calibration image obtained by performing image collection on a hybrid calibration board, the hybrid calibration board comprising a first calibration reference object and a second calibration reference object, and the position of a corner point of the first calibration reference object not being subjected to perspective deformation; according to the position of the corner point of the first calibration reference object in the calibration image, determining, from the calibration image, a reference object image corresponding to the second calibration reference object; determining initial calibration point coordinates of the second calibration reference object according to the reference object image, and correcting the initial calibration point coordinates; and on the basis of the corrected calibration point coordinates, determining image collection calibration parameters corresponding to the hybrid calibration board.
