Hey,
while x,y, positional tracking from 5 m distance seems ok, the z estimation is wrong, but it gets better from closer range, what might be the problem?
Hi Ori,
Thanks for your message.
A few questions regarding your issue :
- Can you please run ZED_Diagnostic_Tool and send the resulting JSON file? This will allow us to know more information about your system.
- In the case of a GMSL camera, please use ‘sudo ZED_Diagnostic_Tool --dmesg’.
- Are you using a specific sample to do your test ?
- What Positional Tracking parameters are you using ? (mode Gen1 or Gen2, imu_fusion…).
Best,

Thank you for the files.
From what I’m seeing, you’re using Gen_1 as parameter for positional tracking.
My recommendation for this would be to try the same tests with Gen_2 instead ( try with and without imu fusion to see in your case if you see better results).
With Gen_2, the drift should be smaller. It performs even better with loop closures ( drift is corrected as the tracked camera sees visual features it has previously collected).
