Enquiry about parameter meaning in ZED360

Hi Zed Team,

Recently I’ve been using ZED360, and I noticed that the documentation of this app (https://www.stereolabs.com/docs/fusion/zed360) seems to correspond to an older version of ZED360.
In the newer version, some options have been added to the UI, but there is no explanation of what these options actually mean.

(1) What does Flip Camera mean? I see that it has three options: Auto, On, and Off.

(2) For Depth Modes, I see Ultra and Neural in ZED360. However, according to the official depth modes documentation
(https://www.stereolabs.com/docs/depth-sensing/depth-modes), the depth modes are Neural Light, Neural, and Neural Plus.
Are the depth modes in ZED360 the same as the official depth modes?
Is Ultra equivalent to Neural Plus, is this a naming mismatch?

(3) For Detection Threshold, my intuitive understanding is that a higher value makes the algorithm more strict, and therefore less likely to produce false positives, such as detecting non-human objects as a human.
Is this understanding correct?

(4) The Body Model setting has three modes: Accurate, Medium, and Fast.
How does this setting affect the calibration result?
Does Accurate detect more human joints, while Fast simply runs the body detection faster?

It seems that the ZED360 documentation lacks explanations for these parameters.
It would be great if the documentation could be updated to cover the new version of ZED360.

This reflects this parameter of the ZED SDK API: Video Module | API Reference | Stereolabs

ULTRA is deprecated with the ZED SDK v5.

No, ULTRA mode is not based on AI processing.

Yes: BodyTrackingRuntimeParameters Struct Reference | API Reference | Stereolabs

You can read more regarding the behaviors of the 3 models in the documentation:

We are going to update it soon

Hi @Myzhar ,

Thanks for the detailed explanation — that clarifies most of my questions.

I still have one remaining question regarding depth modes:

Since ULTRA is deprecated in SDK versions > 5.x, does this mean that for ZED360 we are now expected to only use the NEURAL?

Thanks in advance for the clarification.

Thanks that will be very helpful!

Yes, all the “classic” depth processing methods based on Stereo Matching in v5 have been replaced by AI-based depth estimation methods, NEURAL_LIGHT, NEURAL, and NEURAL_PLUS.

The new methods provide denser and more accurate depth maps, with similar load requirements.
