ZED X Depth Noise on moving ball (~10 meters)

Hi,

I’m experimenting with a ZED X camera (2.2mm lens) for moving balls (quite slow).

Here the ball comes from high and bounce on the ground then on the wall.
The camera has approximately the view of the plot.
We would expect a quite parabolic flight but instead get a saw pattern oscillating on the depth axis (roughly) with >1 meter error which is huge. The approximate distance is ~8 meters and

The depth is calculated using NEURAL_PLUS model.

Does that ring a bell? Is there some way I could improve the depth? I thought about some kind of smoothing but that’s not entierly satisfactory and I feel like we’re too far from the truth.

I made a viewer to see the RGB and Depth both zoomed around the cursor

Which shows me that the ball is “seen” at a depth level (blue pixels = low difference wrt. to aimed pixel = area of same depth).
