Abstract: A portable 3D scanning system collects 2D-profile data of objects using a combination of a laser-stripe positioning device and a video camera which detects the images of the laser stripe reflected from the object. The scanning system includes a laser-stripe generator, a video camera, a scanning mirror attached to a continuously rotating motor, an encoder or a photodiode operationally coupled to the motor, and associated electronics. As the rotating, scanning mirror reflects the laser stripe and variably positions the laser stripe across the object, the encoder or the photodiode generates signals indicating the angular position of the mirror. The video images of the reflected laser stripes are stored on a storage medium, while data relating to the angular positions of the laser stripes recorded in the video images are simultaneously stored on a storage medium. A computer subsequently synchronizes and processes the recorded laser stripe data with the angular-position data to generate a 3D model of the object by applying triangulation calculation and other post-scanning methods, e.g., multi-resolution analysis and adaptive-mesh generation. The multi-resolution analysis, which applies more points to resolve fine details and fewer points for smooth regions of the objects, leads to significant data compression. The adaptive mesh, which include connected polygonal elements and which may have multiple resolutions and tolerances, is generated by the adaptive-mesh generating routine.

First Claim:
Show all 57 claims		 We claim:     1. A portable system for determining a three-dimensional profile of an object comprising:
  • a light-source unit for projecting a stripe of light onto said object and creating a luminous contour line at an intersection of said stripe of light and said object, said light-source unit being adapted to variably position said stripe of light onto said object;
  • an image-detecting device for detecting a sequence of images each containing at least one image of luminous contour line, said image-detecting device producing for each image signals representative of said each image, including signals representative of two-dimensional coordinates of detected contour line, wherein said image-detecting device is one of a TV camera, a video camera and a CCD camera;
  • an angle indicator for generating a signal related to an angle of approach of said stripe of light onto said object for at least one position of said stripe of light on said object; and
  • at least one data storage for storing at least one of pulse signals, audio signals and video signals, wherein said signals representative of said each image are stored as video signals and one of said signal related to said angle of approach of said stripe of light onto said object for said at least one position of said stripe of light on said object and a signal derived from said signal related to said angle of approach of said stripe of light is stored as one of a pulse signal, an audio signal and a video signal.
