A Method of Discrete Measuring and Reconstructing for Complicated Surfaces
A new method for measuring and reconstructing complicated free-form surface shapes is presented. First of all, the normal vectors at points on the surface are computed by using three light sources and by solving Lambertian reflectance map. The dense information on the approximate surface shape at a time can be obtained. Light stripes are then projected onto the surface to increase the accuracy of the measured value. And 3D coordinate values of the points on the stripes are computed by stereovision. Finally, the normal vectors and the 3D coordinate values are incorporated to reconstruct the surfaces. This method enables the accurate 3D measurement of complicated shapes of a surface in a short time.
