Abstract (en)
[origin: WO2014095784A1] 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.
