Verfahren und Vorrichtung zur Messung der Entfernung eines Objektes

DE 10037771 A UPAB: 20020528 NOVELTY - The laser scanners (3a,3b) arranged at a defined spacing are moved, until the scanning beams (4a,4b) converge at a measurement point (6) on an object (2). The object image is picked up using a video camera (7) and the image is processed to set scanners movement for beam convergence and to determine object distance by triangulation principle using scanners position and converging point. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for object distance measurement device. USE - For detecting object distance, 3D profile of an area or objects for precision control of insertion of endoscope, and controlling tools and robots in industrial automation. ADVANTAGE - The measurement is independent of the spatial resolution of the optical detectors and only dependent on the mechanical guides used for moving the scanners, hence precision and reliability are high
