MEASUEMENT TECHNOLOGY OF THREE-DIMENSIONAL CONTOUR THROUGH GRATING PROJECTING COMPOSITE
三维面形的光栅投影合成测量技术

A novel technology is proposed in this paper. On the basis of traditional method of gratingprojecting,the object to be measured is measured in two steps, one is to the left,another right.Afterthen two parts of results,i.e,left and right are combined by certain methods. The measuring resultsprove that this new technique can get rid of the old problems such as shades and limit of size ofobjects.Moreover a new calibration method is presented.
