ABSTRACT:
An optical location system having a beam projection device (11, 51, 12, 13) to illuminate the field of view, and a detector array (29) to detect reflected light (21) from the field of view. The projected beam (13) is incrementably progressed across the field of view and for each increment the reflected points of light (61) detected by the detector (29) are recorded to build a map of the field of view, which is stored as a sparse array having as its first coordinate the angle of projection (A) of the illuminating beam (13) and as its second coordinate the azimuth angle (B) of the reflected ray detected by the detector. The value stored in each element of the array is the angle of the incidence (C) of the horizontal component of the detected ray with the detector.
