  • Publication number: 20190247157
    Abstract: The invention provides a three-dimensional object scanning device using structured lights and method using the same. A combination of specific monochrome light sources is used to construct the content of the structured lights to form a predetermined image, which is projected to the three-dimensional object such as an intraoral object. The combination of blue and green lights effectively eliminates reflective interference of the red or white environment within the intraoral space. Default patterns of the predetermined image are distinguished from one another by using well designed arrangement of color blocks so that specific coding information of location may be embedded and exploited.
