Hi there,

I am using the zed2i as an outdoor measurement tool. I saw the depth accuracy is about 2%-5% when it comes to less than 10m. But when I use it as the measurement tool outdoor, I found the accuracy is quite bad when the distance from the camera is further than 6m.

Case 1. Distance: 9.3m. Traffic sign ground truth: 2.5m. Calculate from depth map: 6.06m. (very bad)

Case 2. Distance: 8.3m. Traffic sign ground truth: 2.5m. Calculate from depth map: 2.43m. (Good)

How I calculate the measurement: Euclidean distance formula.

Parameters:

Neural depth mode.

3.8.2 SDK.

Resolution: both 2k and 1080 are the same.

Is this situation to be expected? How can I calculate the furthest working distance in this scenario?

Another screenshot is showing that the same height fence will give different height results.

Thanks for your suggestion.
