Method and system for three-dimensional spatial position detection of surface points

摘要

A method for the measured spatial 3D position detection of surface points of an object in a photogrammetric online system, in which a surface measurement point is touched by a probe tip. The spatial 3D position of the probe tip at the instant of touching is computed, with respect to a reference system, using an electronic camera. The computed 3D spatial position is stored as data. The electronic camera is rigidly connected to the probe, the camera being pointed away from the object at a target area which covers the volume to be measured. The target area has known reference points which form the reference system.
