Explanation of Measuring Principle

Measuring Principle

The VIVID 9i uses the light-stripe method to emit a horizontal stripe light through a cylindrical lens to the ob- ject. The reflected light from the object is received by the CCD, and then converted by triangulation into distance information.

This process is repeated by scanning the stripe light vertically on the object surface using a Galvano mirror, to obtain a 3D image data of the object.

In addition, a color image of the object is also obtained by scanning the CCD through a RGB filter while the stripe light is not emitted. (A band pass filter is used when stripe light is emitted.)
