摘要：A geodetic instrument is disclosed, wherein an image sensor is used for locatingthe instrument above a de- sired point on the ground. The positioning of the imagesensor with respect to the instrument vertical rotation axis is determined, or calibrated,using a method where two images are captured at different horizontal rotational

positions for the instrument, and where the center pixel of the image sensor is related tothe vertical rotation axis by means of image processing. It is also disclosed how reflectingelements, such as prisms, may be used for providing stereoscopic vision that can be usedfor determining the instrument height above the ground.
