OPTOELECTRONIC DEVICE AND METHOD FOR DETERMINING BIDIMENSIONAL POSITION

摘要

The invention relates to an optical and electronic system for determining a position of an object (2) present on a predefined surface (S), the system comprising at least one emitter (E) emitting a beam (F) covering the predefined surface (S) and exhibiting specific spectral and/or modulation characteristics making it possible to detect it including in the presence of a natural light of high intensity, this system comprising two devices (D1, D2) for detecting an angular direction (a1,a2) in which the object (2) lies and a module (10) for determining the position of the object (2) so as, knowing the position of the two devices (D1, D2) with respect to the predefined surface (S) and the angular direction (a1,a2) in which the object (2) lies with respect to each of the devices (D1,D2) for detecting an angular direction (a1,a2), to deduce therefrom the position of the object (2) on the predefined surface (S) by intersection of the predefined surface (S) and of the two angular directions (a1,a2) determined with respect to the detection devices (D1,D2).
