Vorrichtung und Verfahren zur dreidimensionalen Objekterfassung

DE 10331321 A UPAB: 20050311 NOVELTY - The device for three-dimensional object detection relative to at least one specifiable spatial reference point includes a mobile transmitting device (1) and a receiving device (5) positioned at the spatial reference point, where the transmitting device (1) has an acoustic wave transmitter as well as an antenna unit for radiating electromagnetic waves and is provided with a triggering device which, with touching of the object with the transmitting device (1), generates a signal through which the acoustic wave radiator and the antenna are coupled for a time to radiate sound and electromagnetic waves. The receiving device (5) has at least three or four microphones (6) for spatially separated sound-wave verification as well as a reception antenna for receiving the electromagnetic waves. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (a) a method for three-dimensional object detection; and (b) for application of the device. USE - Field or terrain-surveying, laser scanning, photogrammetry, satellite evaluation and aerial photography e.g. for archeological excavation sites, buildings and buildings interiors etc. ADVANTAGE - Quick, cost-competitive, simple three-dimensional object detection. Enables easy assignment of the objects being detected to semantic information
