| Zusammenfassung: | The present application relates to a 3D camera calibration method and apparatus, and a calibration system. The method comprises: acquiring a scanning point cloud image of a first camera and a scanning point cloud image of a second camera to be calibrated, the scanning point cloud image being a point cloud image generated by scanning a calibration hole on a calibration object; extracting hole center coordinates of a calibration hole in the scanning point cloud image of the first camera to obtain first coordinates, and extracting hole center coordinates of a calibration hole in the scanning point cloud image of the second camera to obtain second coordinates; deriving a normal vector of a plane in which the calibration hole scanned by the first camera is located; calculating extension coordinates of the calibration hole scanned by the second camera in the first camera according to the first coordinates, the normal vector, and preset calibration hole distance data; and computing coordinate conversion relationship |
