Abstract

um objeto é identificado ou rastreado dentro de um volume ao projetar no volume um feixe de luz codificado com uma ou mais propriedades predefinidas para ter uma estrutura ótica predefinida. um detector captura luz da estrutura ótica predefinida refletida pelo volume. ao analisar uma ou mais características de luz da estrutura ótica predefinida refletida pelo objeto, o objeto é segmentado do volume.
