Apparatus and three-dimensional information processing method

The invention relates to an apparatus which uses ioeuvre a method for processing three-dimensional information. It comprises a first optical system 1, a device 5, three shaped beams of projection, a second optical system 2 and a sensor 4 images. The shaped beams are emitted to an object 6 through the first optical system 1, and the optical images formed by the beams on the object are received by the sensor through the second optical system 2 so that the positions of optical images received are detected. The distances between these detected positions and a plurality of positions on the object are measured, giving a three-dimensional information about the object. Application: industrial robots and other devices using optical information, etc. (CF DRAWING IN BOPI)
