Abstract

The invention relates to a method and a system for the high-precision positioning of at least one object in a final location in space. An object (12) is gripped and held by the industrial robot (11) within a gripping tolerance. A compensating variable, which corrects the gripping tolerance, is determined for the industrial robot (11). The object (12) is adjusted with high precision into a final location by the following steps, which repeat until reaching the final location at a predetermined tolerance: recording of image recordings by recording units (1_a, 1_b); determining the current location of the object (12) in the spatial coordinate system from the positions (P_a, P_b) of the recording units (1_a, 1_b), the angular orientations of cameras (2_a, 2_b) of the recording units (1_a, 1_b) which are detected by angle measuring units (4_a, 4_b), the image recordings, and the knowledge of features (13) on the object (12); calculating the location difference between the current location of the object (12) and the final location; calculating a new target position of the industrial robot (11) in consideration of the compensating variable from the current position of the industrial robot (11) and a variable which is linked to the location difference; adjusting the industrial robot (11) into the new target position.
