1. an on-site tridimensional footprint numeralization total processing system comprises support, it is characterized in that, this processing system also comprises optical projection device, two CCD photographic head, motor and computers;

  • Wherein, described optical projection device, two CCD photographic head and motor are contained on the described support;

    The optical projection device is used to shine tridimensional footprint, carries out optical encoding;

    Described optical projection device is in order to providing dot structure light, or line-structured light, or the laser instrument of grid structured light;

    Two CCD photographic head are used for the independent separately optical encoding image of gathering, and before the described CCD photographic head narrow band filter slice are housed;

    And described two CCD photographic head symmetries are positioned over described optical projection device both sides;

    Wherein, the projecting direction of described optical projection device respectively and the angle between any one CCD photographic head axis be 0 the degree to 90 the degree;

    Motor is used for driving described optical projection device under the control of described computer and described two CCD photographic head are done translational motion synchronously;

    Computer, be used to control described motor, the optical encoding image that described two CCD photographic head are gathered carries out digital image analysis, the digital picture captured to described two CCD photographic head merges, and utilize optical encoding image calculation three-dimensional information, utilize quick centroid algorithm to extract the light belt center, and obtain the tridimensional footprint three dimensional point cloud through free-air correction.
