Title (EN) LIDAR SYSTEM WITH FLEXIBLE SCAN PARAMETERS
(FR) SYSTÈME LIDAR AYANT DES PARAMÈTRES DE BALAYAGE FLEXIBLES
(DE) LIDAR-SYSTEM MIT FLEXIBLEN SCANPARAMETERN
Abstract:
(EN) The invention relates to a LIDAR system (100) comprising a laser scanner (101) with at least one laser light source (111). The laser scanner (101) is designed to emit laser pulses (191) into multiple angular regions. A controller is designed to actuate the at least one laser light source (111) in order to emit at least one first laser pulse (191) into a specific angular region and to carry out a LIDAR measurement on the basis of a reflection (192) of the at least one first laser pulse (191). The controller (102) is additionally designed to change at least one scan parameter of the laser scanner (101) on the basis of the LIDAR measurement and to then actuate the at least one laser light source (111) so as to selectively emit at least one second laser pulse (191) into the specific angular region.
(FR) La présente invention concerne un système LIDAR (100) comprenant un dispositif de balayage laser (101) doté d’au moins une source de lumière laser (111). Le dispositif de balayage laser (101) est conçu pour émettre des impulsions laser (191) sur plusieurs plages angulaires. Une commande est conçue pour commander l’au moins une source de lumière laser (111) pour qu’elle émette au moins une première impulsion laser (191) sur une plage angulaire déterminée et pour effectuer une mesure LIDAR en fonction de la réflexion (192) de l’au moins une première impulsion laser (191). La commande (102) est en outre conçue pour faire varier au moins un paramètre de balayage du dispositif de balayage laser (101) en fonction de la mesure LIDAR, puis pour commander l’au moins une source de lumière laser (111) au choix pour qu’elle émette au moins une seconde impulsion laser (191) sur la plage angulaire déterminée.
(DE) Ein LIDAR-System (100) umfasst einen Laserscanner (101) mit mindestens einer Laserlichtquelle (111). Der Laserscanner (101) ist eingerichtet, um Laserpulse (191) in mehrere Winkelbereiche auszusenden. Eine Steuerung ist eingerichtet, um die mindestens eine Laserlichtquelle (111) zum Aussenden mindestens eines ersten Laserpulses (191) in einen bestimmten Winkelbereich anzusteuern und um eine LIDAR-Messung basierend auf einer Reflektion (192) des mindestens einen ersten Laserpulses (191) durchzuführen. Die Steuerung (102) ist weiterhin eingerichtet, um basierend auf der LIDAR-Messung mindestens einen Scanparameter des Laserscanners (101) zu verändern und um anschließend die mindestens eine Laserlichtquelle (111) wahlweise zum Aussenden mindestens eines zweiten Laserpulses (191) in den bestimmten Winkelbereich anzusteuern.
