Abstract
esta aplicação refere-se à captura de uma imagem de um objeto alvo utilizando informação a partir de um sensor de tempo de vôo. em um aspecto, um método pode incluir um tempo de vôo (tof) sistema configurado para emitir luz e perceber uma reflexão da luz emitida e pode determinar uma energia de retorno com base na reflexão da luz emitida. o método pode medir um tempo entre quando a luz é emitida e quando a reflexão é detectada e pode determinar uma distância entre o objeto alvo e o sistema tof com base naquele tempo. o método também pode identificar uma refletância do objeto alvo com base na energia de retorno e pode determinar um nível de exposição com base em uma distância entre o objeto alvo e uma refletância do objeto alvo.
