Abstract
A system for three-dimensional measurement of inaccessible hollow spaces g. sewage canal pipes) by means of a light source and a camera, which are disposed on an inspection head or carrier. A structured light source is used, and the camera and the structured light source have a common entry and exit aperture and have before the aperture at least partially one common optical axis or parallel axes, the distance between which is substantially smaller than the distance between the source point of the pattern and the object-side principle plane of the camera lens.
