Reproducerbar positions- eller holdningsidentifikation af deformerbare kroppe

A moving or deformable body, especially a living body, is measured for reproducible position or location identification in an initial position on a first support. By using a first investigation method during the initial position to optically detect the surface of the body, surface points of the body are detected regarding their three-dimensional spatial position using at least one three-dimensional sensor system and stored as a set of three-dimensional coordinates. The body is then repositioned on the first surface or on another surface. The first investigation method is used again to optically detect surface points regarding their spatial position and stored as an additional set of three-dimensional coordinates. In the following step of the method, the at least two stored sets of surface data resulting from the previous applications of the investigation method are compared, which makes it possible to obtain information regarding changes in position.
