Autofocus

Is there anyway to use autofocus? This is to do additional detection and CV work, but the resolution is quite poor without autofocus

The ARCore camera focal distance is set to a fixed focus tuned for motion tracking. There is not an API that allows you to adjust the focus as that would impact the tracking quality. Sorry!

Makes sense, I think it should be possible in theory, to work with a variable focal length, but I have no idea where to go from here. I'll close this for now, feel free to open it back up if there are new leads. Thanks!

+1 for implementing this feature in a future release. We try to work on enhancing ARCore to be able to use custom tracking markers, it is hard to do computer vision on the unfocused imagery.

Now that ARCore 1.2 has AugmentedImage support (Image Recognition), was this added to the API?

+1 Would be really great to have auto focus(or tap to focus) and improve the image quality to full resolution, just like ARKit.

We are trying to detect certain features, but we are currently very limited in terms of the feature's size and detail level, which makes it unusable for our use case.

That is an urgent issue, please fix it. Detecting codes is currently not possible with ARCore

+1 auto-focus (or tap to focus) would greatly increase the tracking quality that we need in our app

+1 auto-focus. the quality of backgroundimage is not good enough. It has an influence on my image processing

Hi, ARCore SDK for Unity v1.4.0 has been released and Autofocus has been added to it.

This comment might be useful to set auto-focus mode in camera.
