depth sense miss-judge case with D435
Hi dear,
I am now testing several depth sensor for my product of autonomous system.
in my unit test based on some literature, I have one symptom to measure the depth with D435.
as you see the attached picture by your RS viewer, there is some miss-judgement if vertical 5mm stripe pattern is sensed.
can you please let me know why this symptom happen and how to resolve it?
my system is:
- camera on machine can move horizontal direction but no vertical movement.
Thank you for your support.
Best regards

The final page (10) of Intel's camera tuning guide suggests that when dealing with structures that repeat (like a set of stripes), you can either change a setting called the Second Peak Threshold in the RealSense Viewer, or tilt the camera up to 20 degrees from the horizontal.
You could also try printing off the "checkerboard" calibration target image for the 400 Series cameras instead of using the stripe pattern.

A Dynamic Calibration can have a strong positive effect on the quality of the camera image. You are welcome to perform such a calibration. I was suggesting though that you first try just printing off the checkerboard image and putting it on your wall (without doing a Dynamic Calibration) to see if the camera can detect it more clearly than your stripe pattern. :)
