Method and Device for Determining the Position Coordinates of a Target Object

摘要

Method for determining the position coordinates (XM, YM, ZM) of a target object (11) in a measurement range (12) in at least two dimensions (X, Y, Z), with the steps: a target device (13) with a reflector element (31) is positioned at the target object (11), a laser beam (46) is transmitted from a transmitting element (41) of a laser distance measurement device (14) onto the target device (13), at least a part of the laser beam (46) is partially reflected on the reflector element (31), a camera device (15) records an image of the target device (13) with the at least partially reflected laser beam as a light reflection, the focus of the light reflection in the image of the target device (13) is determined, a receiver element in the laser distance measuring device (14) receives the laser beam partially reflected on the reflector element (31) as the received beam, a distance to the target object (11) is calculated from the received beam, a first offset is calculated from a focal length of the camera device (15), the calculated distance to the target object (11) and a first image coordinate of the focus of the light reflection, the position coordinates (XM, YM, ZM) of the target object (11) are calculated from the distance and the first offset.
