Realsense D405 vs D435if

    Hi Pranavmp If the camera is positioned 50-60 cm above the ground then the D435if should be able to capture the object if it is further than around 10 cm away from the camera.

     

    The issue that you are experiencing with the D455 may be that it has a minimum depth sensing distance of around 50 cm instead of 10, so if the camera is 50 cm away from the ground and the object is reaching up 15 cm from the ground, the upper height of the object may be below the D455's minimum depth sensing distance and so unable to be depth-captured properly.  

     

    If that is the case then instead of purchasing a D435if, a simple solution may be to continue to use the D455 and set an option called Disparity Shift to a value of 100 or 200.  Increasing Disparity Shift above its default value of zero reduces the minimum depth sensing distance of the camera and so enables surfaces less than 50 cm from the camera to be more easily captured on the depth image.

    Hi Marty,
    Thanks for the suggestion. We tried this. Unfortunately, D455 didn't do well in our setup with the suggested changes. We did go ahead and tried D435if and is working well.
