Vuforia Camera Max Resolution

February 3, 2020 - 10:40am #2

Hi, apologies if this question has been answered, but I haven't been able to find one.

I am having trouble understanding the device camera resolution limitations when using the Vuforia camera game object.  The max resolution I can get is 1280x720 on a 6th-gen iPad (2019, iOS 13) using Vuforia 8.6.X and Unity 2019.3.0f1.  The native video resolution of the camera on the iPad is 1680x1050 from what I can tell, and the screen resolution is 2048x1536.  Additionally, when I use the Unity ARCamera I get a larger camera resolution than the Vuforia Camera.  

My question is, how do I increase the resolution of the vuforia camera?  What is even happening behind the scenes to crop the native video output so much?

 

Thanks!

Mark

Hi,

After Vuforia Engine is initialized, it controls the camera capture resolution and frame rate via device specific profiles. Within these profiles are "performance sets", which are a collection of camera settings that map to MODE_DEFAULT, MODE_OPTIMIZE_SPEED and/or MODE_OPTIMIZE_QUALITY

Each the above mode uses a specific resolution. Each mode has been carefully tuned to facilitate the optimal experience. MODE_OPTIMIZE_QUALITY provides the biggest resolution however this will usually not come close to the devices camera resolution.

This is a trade-off performance vs experience, basically the larger the images are, the more cpu your phone will use to recognize and track the image.

In your case I would try the MODE_OPTIMIZE_QUALITY option to see a difference.

Thank you.
