Large systematic error increase versus range using D435i

[JeffR1992]

I have a few D400 series cameras that work well, but one of my D435i cameras produces very large systematic errors as I increase the range from a target. For instance, at a range of about 3.5 meters I have a systematic error of about 0.5 - 0.6 meters. I've performed on-board calibration and focal-length calibration using the RealSense Viewer and the instructions given here, but this hasn't removed the large systematic error that I'm seeing. Note that this doesn't seem to be a tare calibration issue, since the error grows with range and is not at a constant offset. Is there anything that I can do to sort this out?

In case this information is useful, I'm performing the tests at a resolution of 1280x720 at 30 fps, with projector power set to 150 mW, and the IR dot projector points can be seen well on the target at a range of 3.5 meters. I'm also using the latest camera firmware and RealSense Viewer software.

Hi @JeffR1992 Do you see improvement in the depth measurement if you reset the camera to its factory-new calibration values in the RealSense Viewer using the instructions at #10182 (comment)

Hi @JeffR1992 Do you require further assistance with this case, please? Thanks!
