Title (EN) LASER RANGE FINDING WITH ENHANCED UTILIZATION OF A REMOTELY LOCATED MIRROR
(FR) TÉLÉMÉTRIE LASER ET UTILISATION AMÉLIORÉE D'UN MIROIR SITUÉ À DISTANCE
Abstract: front page image
(EN) A laser range finder identifies and tracks a remote mirror with variable placement in a field of view (e.g. a roadside mirror at an traffic intersection) and generates a dense non-uniform subset of outgoing laser pulses designed to cover the mirror portion of the field of view, thereby interrogating or data mining the indirect field of view offered by the remote mirror. In several embodiments a light detection and ranging (LIDAR) system, learns the position of a remotely located mirror, then identifies a subset of the laser reflections that have undergone deflection by that remote mirror and performs a correction step in the process of calculating 3D locations for the deflected subset of laser reflections.
(FR) L’invention concerne un télémètre laser, lequel identifie et suit un miroir distant à positionnement variable dans un champ de vision (par exemple, un miroir de bord de route au niveau d'un carrefour) et génère un sous-ensemble dense non uniforme d'impulsions laser sortantes conçu de manière à couvrir la partie miroir du champ de vision, ce qui permet d'interroger un champ de vision indirect offert par le miroir distant, ou d’en explorer les données. Dans plusieurs modes de réalisation, un système de détection et de télémétrie par ondes lumineuses (LIDAR) apprend la position d'un miroir situé à distance, puis identifie un sous-ensemble des réflexions laser qui ont subi une déviation par ce miroir distant et effectue une étape de correction dans le processus de calcul d'emplacements 3D pour le sous-ensemble dévié de réflexions laser.
