  • 3D color information acquisition method and 3D color information acquisition device
    Patent number: 7415151
    Abstract: A method of acquiring 3D color information and a 3D color information acquisition apparatus, suitable for obtaining a 3D model of an object, use a pattern light source to acquire topography data for the object. More than 3 basic colors are used to construct the pattern to increase resolution with great number of color combination. According to the color composition and combination, color distortion caused by model projection can be prevented, thereby increasing the reliability and broadening the application of the color acquisition device and method.
    Type: Grant

  • Single lens instantaneous 3D image taking device
    Patent number: 6580557
    Abstract: The present invention discloses a single lens instantaneous 3D image taking device for the application in digital image taking. The digital image taking device contains a lens, an aperture disk and a single sensor installed and aligned in a straight line. The aperture disk has three off-optical-axis apertures with different angular coordinates that are installed with red, blue, and green filters, respectively, for light to pass through. When light passes through the lens and the three apertures on the aperture disk, it will be projected onto the sensor, giving image and color information from three different perspectives. Finally, through color separation and image correlation, a precise 3D range image and color information can be obtained.
