Picture is shifted/misaligned sometimes

The Problem

Systems works fine most of the time:

but sometimes it produces a reading like this:

Why does this happen?

(The logfile shows problems with wifi, but I did a firmware upgrade on the router today ;-) )

The camera (OV2640) always delivers different image quality (because of AEC, AEC2 ......) and since your image is relatively dark, it can happen that the alignment fails. Therefore, you should make the picture brighter(e.g. increase LED intensity) and make the alignment markings a little smaller.

[emc02]

LED is at 100%, trying to change the markers. But when you say it's just a problem of my poor image quality and no bug then it's just my problem. And I know there is also a lot of dirt inside...

[SybexX]

You could try to increase CamGainceiling https://jomjol.github.io/AI-on-the-edge-device-docs/Parameters/#parameter-camgainceiling

And I know there is also a lot of dirt inside...

That shouldn't matter because your digit numbers and the arrows seem to be clean.
For the analog ROIs is only important the red arrow, the scale around it is not used.
