Title (EN) LIDAR BASED 3-D IMAGING WITH FAR-FIELD ILLUMINATION OVERLAP
(FR) IMAGERIE 3-D À BASE DE LIDAR AVEC CHEVAUCHEMENT D’ÉCLAIRAGE EN CHAMP LOINTAIN
Abstract:
(EN) Methods and systems for performing 3-D LIDAR measurements of objects simultaneously illuminated by two or more beams of light in the far field are described herein. A 3-D LIDAR based measurement device simultaneously emits at least two beams of light into a three dimensional environment from different locations. A portion of the three dimensional environment is simultaneously illuminated by the two or more light beams at a distance of at least five meters from the LIDAR device. However, the two or more light beams do not overlap at a distance less than five meters from the LIDAR device. The beams of light are slightly divergent, having highest intensity at the device and steadily lower intensity further away. By overlapping illumination beams in the far field, but not near the LIDAR device, overall intensity is maintained at moderate levels throughout the field of view of the LIDAR device.
(FR) La présente invention concerne des procédés et des systèmes pour effectuer des mesures LIDAR 3-D d’objets simultanément éclairés par deux ou plus de deux faisceaux de lumière dans le champ lointain. Un dispositif de mesure à base de LIDAR 3-D émet simultanément au moins deux faisceaux de lumière dans un environnement tridimensionnel depuis différents emplacements. Une partie de l’environnement tridimensionnel est simultanément éclairée par les deux ou plus de deux faisceaux de lumière à une distance d’au moins cinq mètres du dispositif LIDAR. Cependant, les deux ou plus de deux faisceaux de lumière ne se chevauchent pas à une distance inférieure à cinq mètres du dispositif LIDAR. Les faisceaux de lumière sont légèrement divergents, ayant une intensité maximale au niveau du dispositif et une intensité diminuant régulièrement en s’éloignant. Par chevauchement des faisceaux d’éclairage dans le champ lointain, mais pas à proximité du dispositif LIDAR, l’intensité totale et maintenue à des niveaux modérés dans l’ensemble du champ de vision du dispositif LIDAR.
