  Seems like it is working, but does not want to measure distance unless I am looking at the center of a frame? The edge of measuring one thing to another seems to have a dead zone filled with zeros? Do I just ignore 0? Is there a way to not get zero?

  Hi Kirkpennock  You can quickly perform a re-calibration of depth sensing in the RealSense Viewer by going to the More option near the top of the options side-panel and selecting On-Chip Calibration from its menu.

  The On-Chip calibration will provide a 'health check score' of the camera's calibration and offer the ability to write a new calibration to the camera hardware or perform the calibration process again to attempt to achieve a better calibration result.

  A more robust, advanced recalibration of the camera can be performed with the RealSense SDK's Dynamic Calibration tool.  If you are using Windows then you can download the tool from the link below.

  If you are using Linux then installation instructions can be found on page 14 onwards of the tool's user guide.

  In regard to the 'dead zone' of zeroes at the edge: if it resembles a rough edged black area on the left hand edge of the image like the image in the link below then this may be an 'Invalid Depth Band'.  The band is a normal phenomenon and does not indicate a problem with the camera.

  As well as using the Viewer to assess depth quality, you can also use the Depth Quality Tool to receive feedback about depth image quality and the amount of depth error.
