I have this problem too. Have you solved the problem? In fact, I found the same problem on the Android pad.

Just posting to say that I still have to deal with this question from co-workers and clients CONSTANTLY. And it might be my mind playign tricks on me, but it seems to be even worse on the 2017 iPad Pro.

To get the entirety of our Tracker in view, on the default iPad camera app, you have to be about 0,5m away. In Vuforia, you have to be almost 1,5m away.

I just want to understand WHY this can't be fixed. Is it really not possible to get the full resolution camera feed from the camera? *Bangs head against wall*

It's such a huge difference in FOV from the default app (No letterboxing), to a vuforia app (No letterboxing). Is it really just Apples fault? Could you expose some more parameters to just let us experiement?

Having to shrug and say "I don't know." every single time someone comments on this, is tearing me apart...

Hello,

The "zoomed" look of camera image is the result of 2 combined factors:

1. The source image is actually delivered by the device camera already slightly "zoomed" (or "cropped") with respect to the camera image at resolutions that are not used by the native camera app. This is not a result of Vuforia's implementation, but of the OEM's.
2. In addition to the scaling by iOS in #1, Vuforia camera rendering applies additional image scaling so that the camera image can entirely fill the device screen. This scaling is necessary (and mathematically correct) in order to avoid image distortion due to the different aspect ratio of the camera image w.r.t. the screen. It also avoids black side bands (i.e. letterboxing) from appearing at the top / bottom (or left/right) of the rendered image.

The combination of the 2 effects above can result in an overall scaling which appears to be more "zoomed" than the camera's native resolutions, which are an optimized selection per device by the OEM.

Thanks.

same problem here on ipad pro. Any solutions will be appreciated!

Is it possible to render the full frame on iPad Pro 2732x2048 in Vuforia? The cropped in camera looks very bad.

Hello,

Not all devices utilize the same performance sets. This is due to per-device differences in the camera and rendering pipelines.

Reviewing the current configurations for the two variants of the iPad Pro, I'm seeing the following performance sets that are applied to SDK 6.X:

MODE_OPTIMIZE_SPEED: 1280x720

MODE_DEFAULT & MODE_OPTIMIZE_QUALITY: 1920x1080

These resolutions may not be the same used as what is utilized for background rendering on the native camera app, so they may be zoomed and/or cropped. This is similar to what was mentioned in the linked article.

Thanks.
