Patent ID: 7032458

Claim:
A mobile measurement system of three-dimensional structure comprising: Measuring equipment for measuring three-dimensional structure of a measurement object, A barrow for moving measurement which measuring equipments are mounted and is driven by one wheel that contacts with a travel surface, Said measuring equipment is composed by: A slit floodlight to illuminates slit light to the measurement objects, A digital still camera to take a picture of said object which is illuminated by the slit light from the direction of across that of the slit light and, A three-dimensional structure calculating device which calculates and outputs the three-dimensional structure of said object by using a light plane range-finding method from the each position of said floodlight and the camera, the direction of the illumination of the slit light of said floodlight, the direction of taking a picture of said camera, and the picture which is taken by the camera, Said barrow has a rotation angle sensor which detects the rotation angles around the mutually orthogonal three axes, a wheel revolution sensor which detects the revolution of the wheel and, a measurement position and direction calculating device that calculates the each position of said floodlight and the camera, the direction of the illumination of the slit light of said floodlight, the direction of taking a picture of said camera at the measurement by said equipment in accordance with an information of self-contained navigation from said rotation angle sensor and an information of moving distance from said wheel revolution sensor and transmit the result of the calculation to said three-dimensional structure calculating device.
