发明名称 Determining coordinates of a target in relation to a survey instrument having a camera
摘要 A method is disclosed for determining coordinates of a target in relation to a surveying instrument wherein a first image is captured using a camera in a first camera position and orientation, a target is selected by identifying an object point in the first image, and first image coordinates of the object point in the first image are measured. The surveying instrument is then rotated around the rotation center so that the camera is moved from the first camera position and orientation to a second camera position and orientation, while retaining the rotation center of the surveying instrument in a fixed position. A second image is captured using the camera in the second camera position and orientation, the object point identified in the first image is identified in the second image, and second image coordinates of the object point in the second image are measured. Target coordinates in relation to the rotation center of the surveying instrument are then determined based on the first camera position and orientation, the first image coordinates, the second camera position and orientation, the second image coordinates, and camera calibration data. Furthermore, a surveying instrument for performing the method is disclosed.
