Issue Description

Hi, I am new to the realsense SDK. I am trying to work on the depth values obtained from the realsense in c++ on Jetson nano. I noticed that the depth values obtained in the realsense-viewer does not reflect the real distance to the object. The max value I get is 0.13m. But when I connect the same camera to my desktop which is running Windows 10, I can see that the depth values obtained are very close the actual distance to the object. In both cases the camera and the object are placed in the same position. The parameteres on the realsense-viewer have been kept the same. Can you please tell me if there is something wrong i am doing. For reference see below the snapshots from realsense-viewer. Thank you in advance for your help and answers.

@kevinpaulsudarshan Seems the snapshot of Ubuntu(Jetson nano) doesn't show depth. Could you please provide another snapshot and specify where you saw 0.13m difference?

[kevinpaulsudarshan]

Here are two snapshots of the same scene on Windows and Ubuntu respectively. In Ubuntu I have set the "Motion to depth range" to 220. In Windows the same parameter is 9. The distance to the object on Ubuntu is 0.12m and on Windows is 0.56m(left bottom corner of the image in realsense-viewer). The distance to object on Ubuntu always caps out at 0.13m. 0.13m is not the difference but the maximum distance shown when I move the cursor over the image in realsense-viewer.

@kevinpaulsudarshan Did you get such issue if you set "Motion to depth range" to 9 on Ubuntu? And could you please provide SDK version you used? Thanks!

@kevinpaulsudarshan I couldn't reproduce the issue with the latest SDK. Could you please try with the latest SDK also? Looking forward to your update. Thanks!
