Abstract
Target point recognition method including emitting electromagnetic radiation to illuminate targets, moving the scanning beam within a predetermined angular range in order to scan the surveying environment, detecting reflections of the electromagnetic radiation on the targets, wherein the targets are defining the target points, and determining the angle to the target points. The method further including a capturing procedure with capturing an overall image of the surveying environment, wherein the overall image comprises at least one single image taken by the camera, and determining target points and their angle on the overall image by image processing by matching targets with one or more predetermined search criteria, storing the target points together with their angle a data base, and displaying the overall image together with marks for indicating a position of the target points detected within the scanning procedure and the capturing procedure in the overall image.
