摘要
Track-laying inspection vehicle for inspecting tunnel-like ducts, shafts or the like with a remote-controllable drive and a camera (4).

From the shape of the shadow pattern transmitted via the camera (4) on an obstacle, the distance, shape and inclination of the obstable can be determined. IMAGE
