Abstract
The present disclosure is directed to calibrating a three-dimensional camera in X-ray imaging, and a storage medium. The techniques described include: acquiring a three-dimensional image of a calibration plate captured by a three-dimensional camera, where the calibration plate includes a positioning marker, and the calibration plate has a predetermined distance from an X-ray tube; determining first three-dimensional coordinates of the positioning marker in a three-dimensional camera coordinate system on the basis of the three-dimensional image; determining second three-dimensional coordinates of the positioning marker in an X-ray tube coordinate system on the basis of the distance; and determining, on the basis of the first three-dimensional coordinates and the second three-dimensional coordinates, a transformation matrix adapted to calibrate the three-dimensional camera. The described techniques may address the system error caused by the coordinate system difference.
