| 摘 要： | 基于光栅的三角测量方法是将光栅投射到被测物体表面,CCD接受由于物体表面高度起伏产生的变形光栅像,根据光栅变形量与高度的关系,恢复被测物体的三维形貌。提出了一种基于无衍射光栅的三角测量的定标方法。该方法通过空间坐标变换,方便地求出摄像机的内外参数,从而获得被测物体的三维信息。

| Abstract: | The method for triangulation based on grating is to project grating on the surface of the object,CCD accepts the deformed grating image produced by fluctuation of facial height of the object.According to the relation between deformation and height,the object′s tridimensional appearance is resumed.This paper puts forward a kind of calibration method for triangulation based on non-diffracting grating.The methord could obtain internal and outer parameters of vidicon conveniencely by transform of spacial coordinate and acquire the 3-D information of the object on-measure. |

| Keywords: | camera calibration non-diffracting grating triangulation tridimensional appearance |
