Hi
We are using the open3d function with the OAK-D-Pro PoE model and sometimes the z value is inverted.
Here is the pictures of the normal value reversal.
Currently, the expected problem is identified as a problem calculated through the estimate_normal function in open3d, but it needs confirmation.
If you need any additional information, please ask us we will answer it as soon as possible.
