  • Device and method for scanning an object on a working surface
    Patent number: 8593512
    Abstract: A device and method for scanning an object on a working surface, the device comprising: a body located adjacent to the working surface; two or more cameras mounted on the body at a location elevated adjacently above the working surface for capturing images of the object on the working surface, the two or more cameras being angled such that their range of image captures overlap and the common overlapping region of the range of image captures of the two or more cameras corresponds with the size of the working surface, the two or more cameras being spaced apart such that each of the two or more cameras captures a different angle of the common overlapping region; and a processing unit capable of correcting skewed images of the working surface captured by the two or more cameras and capable of converting the images captured by the two or more cameras into a three dimensional image.
