The project we are proposing is a structured light 3 dimensional scanner. The technique will consist of a laser line projected onto an object that is sitting on a rotating platform. A camera will record images at a slightly offset angle from the laser in order to use a process called triangulation to determine how far from the camera the laser is shining. The platform will rotate by a motor that is controlled by a digital signal. The whole system will be controlled with an embedded system consisting of an FPGA to move the motor and coordinate the images taken with the position of the platform. Some data can be processed directly in the FPGA, such as determining which pixels in the RGB image are laser light and converting the image to black and white. The black would be where the laser is shining and the white where it is not. The black and white data would be sent to a computer workstation, and using algorithms we write, would be converted into three dimensional data points. This data will then be sent to a program like MATLAB and constructed into a 3D image.
