Z-distance for Custom object detector significantly higher than actual distance

Software Python
1

I have found that the z-distance for objects that are detected is significantly too high. Does anybody know more about this issue?

Hi @Phyrokar,

Can you tell me some more about your setup? What camera are you using? What version of the SDK are you using?

Can you please share how you are measuring these errors? Have you tried different DEPTH_MODEs ?
Are you using the factory calibration or have calibrated the cameras using our tools?

Hello, thanks for your quick answer.

I am using ZED SDK 4.0 in docker with two ZED2i.
I tried depth mode Neural and Ultra and it seems, that I have the issue with both.
I am using factory calibration.

It just started a few days ago out of nowhere.

Could you share an SVO file that showcases the issue that you are encountering, with a known distance to an object so that we can investigate on our end?

Hello,
it looks like I have solved the problem. Apparently the origin of the problem was that I mounted the zed/resurces folder in the container. I did this so that I didn’t have to carry out the Neural Depth engine optimization every time. Apparently the ZED SDK doesn’t like that?!

In order for us to reproduce the issues, can you share:

  • the docker image that you are using
  • the result file after running the ZED_Diagnostic tool

Thank you
