Abstract

são reveladas técnicas para geração de mapas de profundidade em um sistema de luz estruturada no qual um transmissor ótico é inclinado com relação a um receptor ótico. o transmissor ótico tem o eixo geométrico ótico do transmissor em volta do qual a luz estruturada se espalha, e o receptor ótico tem um eixo geométrico ótico em volta do qual um reflexo da luz estruturada pode ser captada. o eixo geométrico ótico do transmissor e o eixo geométrico ótico do receptor se interceptam um ao outro. um circuito de processamento compensa o ângulo de inclinação no padrão refletido de modo a se gerar o mapa de profundidade.
