| 摘 要： | 本文提出一种新的物体三维面形测量技术,它在传统的光栅投影测量法的基础上,对待测物体的左右两边分别进行测量,然后将上述的结果进行空间合成。这种方法能够有效地解决目前三维测量中存在的阴影及测量范围不大等不足和问题,为这种方法的实用性提供了广阔的前景。

| Abstract: | 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. |
