Detailed Description

Grabber for Intel Realsense 2 SDK devices (D400 series)

Note: Device width/height defaults to 424/240, the lowest resolutions for D400 devices.; Testing on the in_hand_scanner example we found the lower default resolution allowed the app to perform adequately.; Developers should use this resolution as a starting point and gradually increase to get the best results
