Title (EN) CODE DOMAIN POWER CONTROL FOR STRUCTURED LIGHT
(FR) COMMANDE DE PUISSANCE EN DOMAINE DE CODE DESTINÉE À DE LA LUMIÈRE STRUCTURÉE
Abstract:
(EN) Systems and methods for controlling structured light laser systems are disclosed. One aspect is a structured light system. The system includes a memory device configured to store a depth map. The system further includes an image projecting device including a laser system configured to project codewords. The system further includes a receiver device including a sensor, the receiver device configured to sense the projected codewords reflected from an object. The system further includes a processing circuit configured to retrieve a portion of the depth map and calculate expected codewords from the depth map. The system further includes a feedback system configured to control the output power of the laser system based on the sensed codewords and the expected codewords.
(FR) L'invention concerne des systèmes et des procédés permettant de commander des systèmes lasers à lumière structurée. Un aspect de l'invention concerne un système à lumière structurée. Le système comprend un dispositif de mémoire configuré pour stocker une carte de profondeur. Le système comprend en outre un dispositif de projection d'image comprenant un système laser conçu pour projeter des mots de code. Le système comprend en outre un dispositif récepteur comprenant un capteur, le dispositif récepteur étant configuré pour détecter les mots de code projetés réfléchis par un objet. Le système comprend en outre un circuit de traitement configuré pour extraire une partie de la carte de profondeur et calculer des mots de code attendus à partir de la carte de profondeur. Le système comprend en outre un système de rétroaction configuré pour commander la puissance de sortie du système laser sur la base des mots de code détectés et des mots de code attendus.
