其次，为了控制多传感器视觉测量系统而构建了CAN总线控制系统。

Secondly, the CAN bus control system for controlling multi-sensor visual measuring system is carefully structured.

结构光测距技术的主要缺点是无法获取摄像机看不到或光源照不到的点的数据。为此，采用冗余多传感器构成无影视觉坐标测量系统。

The main shortcoming of range finding technique with structural light is that it is unable to obtain the data of points which are sightless by pickup camera or can't be illuminated by light source.
