Thanks a million @Alex-Kushleyev that certainly explains the effect - I really appreciate you taking the time

I understand now @Alex-Kushleyev thanks for the explanation

Hi @Alex-Kushleyev I have changed to the EIS drivers in order to test the MISP (you kindly gave me that information on another post) and I am not at all certain the same issue exists on these drivers.

I know that I was testing with the default small and large streams (1024x768 and 4056x3040) and if I change the FPS to any value other than 30fps the digital zoom effect occurred. I would need to go back to the default driver and settings to double check.

However, I am likely to stick with the new drivers as they are very impressive so we could park this question for now.

Thanks a million @Alex-Kushleyev

I assume the camera is run in sync'ed mode to produce clearer images for computer vision purposes - is that correct?
If that is the case would changing driver potentially reduced the tracking accuracy?

@Alex-Kushleyev understood,

Thanks again I will give this a try - fingers crossed

@Alex-Kushleyev thanks a million for this information (and the beta drivers) Alex it is very helpful.

I am using voxl-camera-server version 2.1.1 (voxl-suite 1.4.1)
From your information I will try 3840x2160 and 4040x3040 at 60fps to see what the performance is like.

@tom I have done that are there are three potential resolutions.
However, only the 1936x1080 produces a valid stream.

When I capture a raw bayer at 4056x3040 then the majority of the image is black. It is as if the 1080p image is put into a 4k container.

Any ideas what I could be doing wrong?

@tom I was giving imx412-fpv-misp a try and was wondering can the resolution of the stream be increased?
Changing the values in the voxl-camera-server.conf file results in a corrupted stream

Cheers @tom ill give it a try

Hi,

I see in the voxl camera server gitlab project it mentions imx412-fpv camera - what is required to enable this for testing?
It doesn't appear as an option on the voxl-configure-camera script.

Hi,

I have noticed that if I increase or decrease the frame rate of the IMX412 camera in voxl-camera-server.conf the fov of the images changes quite significantly.
It is as if a digital soon has been applied to the image.

Is there any way to prevent this - I assume is it driver related.

Any advice would be appreciated

Hi,

I have noticed that if I set the exposure max value to greater than 15ms the frame rate of the stream half to 15fps.
Is that a limitation of the camera (the shutter type perhaps)?

Is it possible to lock the frame rate to 30FPS as long as the max exposure is less than 33.3ms?
Any feedback would be appreciated

Cheers
