Camera auto focus not work any more in Vuforia 6?

August 17, 2016 - 12:43am #1

Hello,

Could any one help me with Camera auto focus ?



It doesn't seem to work any more with recent released Vuforia.



I'm using Vuforia 6.0.112 and set  Camera Focus Mode to "FOCUS_MODE_CONTINUOUSAUTO"

Dear Medabit,

Thank you so much for your help.

I'll send you the binaries of two builds, one is with older vuforia and another one with latest Vuforia.

Hello,

There is no indication of a regression when setting the various focus modes in Vuforia 6. If you send me binaries for each of your builds (one for the working, one for the not working) via PM, I can try and evaluate on our device.

The Vuforia 6 Best Practices sample app Books still has a scanline animation. The logic for this animation was taken out of the SDK and moved into the sample app. This allows developers to create their own experience rather than being forced to use the one created by Vuforia for our CloudReco feature.

The feature points animation was derived via proprietary methods in the SDK and is no longer available.

Thanks

Dear medabit,



Thanks for your comment.

Camera auto foucs is working fine with my app which is on app store now. The app was built with older Vuforia. The problem is that when I updated to new Vuforia, Auto focus does not work anymore. Do you have any idea why ? Does Vuforia stop support Camera Auto Focus?

I just found out, Scanline stopped working also with recent Vuforia.

 

Thanks,

Hello,

In our experience, performance of camera features, like auto-focus, are OEM dependent. Vuforia does not implement these types of camera features. Rather, we call the native OS APIs from the application layer on behalf of the app. This is because the camera behaves as a singleton while a Vuforia session is running.

I just did a quick test of the same Vuforia sample app on two different devices where FOCUS_MODE_CONTINUOUSAUTO is set. On a Samsung Galaxy S6 Edge, continuous auto focus was slow and the picture remained blurry for excessive amounts of time. For the Nexus 5, continuous auto focus was crisp and adaptive to changes in the camera frame's focus.

Thanks
