Abstract
The electro-optical system for determining position and orientation of a mobile part comprises a fixed projector having a center of projection (O) and a mobile part. The projector is rigidly linked with a virtual image plane, and the mobile part is rigidly linked with two linear sensors defining a first and a second direction vector. The fixed part projects onto the image plane and onto the sensors patterns, not represented, forming at least two secant networks of at least three segments that are each parallel. The two electro-optical devices are coplanar and their directions secant, the orientation and the position of the mobile part are determined by calculating the positions of the projections on the image plane of a first triple of points comprising the projections of three points.
