I am trying to use ZED2i to make measurement of objects si I need accurate depth measurement.
I try to measure leaves distance but when I compare distance with L515 I see on some points large distance error
Hi @bpasserat
the problem is the FILL parameter.
It must not be used to measure depth because it introduces smooth estimated values to “fill the holes”, so in the zone where a depth hole was present, you can retrieve not valid depth values.
The FILL model has been introduced for a better AR/VR experience, not for real depth values estimation.
Do you have hints about how the “fill the hole” works ?
I checked the whole area on the left and i did not find any points with the correct value.
Does it mean if I use STANDARD mode I will only have NaN ?
Hi @bpasserat
the FILL mode has been created to add missing depth information when using “standard” stereo vision algorithms.
NEURAL depth mode is different, the depth map is created by using AI and the resulting depth map is more dense, that’s why the FILL mode does not add too much new information.
Like I told you before, FILL mode must not be used to extract depth information, it’s an algorithm to generate better “visual” data to be used in AR and VR.
When you get a depth map with small gaps around object contours, that’s expected and it’s caused by the parallax.
