Detailed Description

Grabber for davidSDK structured light compliant devices.

The davidSDK SDK allows to use a structured light scanner to fetch clouds/meshes.
The purpose of this grabber is NOT to provide all davidSDK functionalities but rather provide a PCL-unified interface to the sensor for basic operations.
Please consult the David-3d wiki for more information.
