On 4.0.6 with a Zed2i I used a confidence threshold of 0 and got many valid depth values. On 4.0.7 I get only nan depth values. If I change the threshold to 1 I start getting valid depth values. Is this expected? If so please provide more details about how these new ranges should be interpreted and why it changed.
In a similar scene I get more valid values on 4.0.7 with confidence=1 than I do with 4.0.6 with confidence=0. If the depth model has improved great; however, If the model is giving more values that might be of lower quality that is problematic.
what is the depth mode that you are using?
The meaning of the parameter is explained here: RuntimeParameters Struct Reference | API Reference | Stereolabs
Neural. I understand the concept of the confidence values. I want to understand why performance and thresholds changed in 4.0.7 after remaining the same through 4.0.0-4.0.6.
Yes, I just received the confirmation that something changed for the NEURAL depth mode.
The confidence of the neural network was adjusted to more accurately estimate low-quality depth pixels, such as flying pixels.
We will add this missing information in the changelog of v4.0.7.
