Abstract

trata-se de um sistema de detecção de profundidade para capturar uma imagem que contém informações de profundidade de um objeto. em uma modalidade, um dispositivo de detecção de profundidade para uso em combinação com múltiplos dispositivos de detecção de profundidade para capturar uma imagem que contém informações de profundidade de um objeto compreende um transmissor quase infravermelho que compreende um laser com a capacidade de produzir um feixe de luz quase infravermelha, um elemento óptico difrativo posicionado para receber um feixe de luz emitido a partir do laser, do elemento óptico difrativo e uma lente de colimação, e um receptor de quase infravermelho acoplado ao transmissor em uma posição relativa, sendo que o receptor compreende uma montagem de sensor com a capacidade de produzir uma imagem da luz recebida, em que o dispositivo de detecção de profundidade é configurado para transmitir e receber feixes de luz quase infravermelha durante um período de tempo que é diferente de qualquer outro dentre dois ou mais pares de transmissor-receptor dos dispositivos em comunicação com o dispositivo de detecção de profundidade.
