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 first camera in a first camera position and orientation, a target is selected by identifying at least one object point in the first image, and first image coordinates of the object point in the first image are measured. In at least one embodiment, a second image is captured using a second camera in a 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 of the target 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 first and second camera calibration data. Furthermore, a surveying instrument for performing the method is disclosed.

The method includes, in at least one embodiment, capturing an image using a camera in the surveying instrument; selecting a target by identifying an object point in the image captured by the surveying instrument; calculating first horizontal and vertical rotation angles based on the object point identified in the image; rotating the surveying instrument over the first horizontal and vertical rotation angles to an intermediate line of sight; measuring a distance to a point along the intermediate line of sight; and calculating second horizontal and vertical rotation angles based on the object point in the image and on the measured distance. In at least one embodiment, the method may be implemented using computer software, hardware, firmware or a combination thereof. There is also disclosed a surveying instrument in which at least one embodiment of the method is implemented.

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.
