Unstable rotation of 3D bounding box from custom detector

Software
1

Hi, I have a ZED X, with ZED SDK 5.0.5. I’m using a custom YOLO detector, and the ingest functionality of the ZED SDK to retrieve 3D bounding boxes.

Recently, I’ve noticed that the retrieved 3D bounding boxes are very unstable. They appear to have approximately the correct shape and position, but they rotate almost randomly. even when there is no movement.

I have taken some SVO recordings, and I can reproduce the error with one of the “custom detector” samples.

Below are some images showing the effect from a short SVO capture. The blue box is the 3D bounding box projected onto the image.

Have you seen this before? Please let me know if you need more information, including the SVO file.

Thanks!

Hi @paul.morrison,

This is definitely not expected, I suspect something is happening with our tracking algorithm in this sequence.

Could you send your SVO(s) + the ZED_Diagnostic.json log file so we can investigate? You can send at support@stereolabs.com if you wish to share anything private.
