Paper Abstract

A laser profiler in machine vision integrated sensor that scans the inspected object's surface by the rotation of the structured light is designed based on the optical triangulation. The system parameters have been optimized for a harmonious arrangement among the range resolution, the measuring accuracy and the shadow effects. The point-to-point mapping relationship among the 2D images and 3D surfaces from the different views and orientations can be developed by means of the spatial geometric correspondence. Moreover, the intensity, color and texture information from CCD images can be affixed to the entire 3D surface. As a result, near range data fusion in machine vision integrated sensor can be realized.
