Abstract (en)
[origin: WO2008038328A2] A process for identifying the position of an object in space comprises a step of illuminating the object with a plurality of rays of light distributed in a known way, for creating a set of illuminated points on the surface of the object and a step of detecting the geometric configuration of the set of illuminated points. Then, a first comparison step between said geometric configuration and a saved three- dimensional surface structure of the object allows the discovery of a substantial correspondence between the geometric configuration detected and at least one geometric configuration belonging to the saved three-dimensional surface structure. Finally, there is an at least implicit step of identification of the position of the object in space based on the comparison between the position in space of the geometric configuration detected and the position of the same geometric configuration detected on the saved three-dimensional surface of the object. The claims also refer to a process for placing an object in space based on the position identification process.
