Abstract

Over last two decades, 3-D vision methods have been developed rapidly and have become an important research field. Structure light 3-D vision technology is a kind of active 3-D vision method. When the structure light's pattern are coded by black and white stripes, we are prone to get incorrect data because of difficulty of seeking correspondence relation, therefore conventional 3-D vision technology using structure light has some limits. In this paper, we put forward a new structure light pattern based on hue information. Each color in real world can be signified by hue, saturation and lightness, and we designed a kind of new pattern, which includes eighteen colors. The shape of objects was acquired and reconstructed though triangular relation. According to difference of hue, processing software can find corresponding relation between distorted stripes and originally regular stripes, and avoid incorrect corresponding using conventional pattern of structure light, such as B/W stripes. Finally the experiment result was given.
