camera Quality with XPeria tablett z

By mnaulet on Thu, 06/13/2013 - 11:52

Hello,

I've bought a sony experia tablet Z.

When I'm try to make an application with vuforia and unity 3d, the rendering quality is poor.

I've set camera setting to optimize quality.

What can I try to have better rendering ?

Thanks

Hi, when you say "rendering quality", do you refer to the resolution of the camera image ? or also about the rendering of the 3D models (augmentation) ?

Hi,

It's only the rendering camera, the augmented model is good.

Thanks

Hi. This could be simply due to the fact that the camera image is limited to 640x480 or similar resolution, while your tablet has a fairly wide screen, which might make this more noticeable.

Could you attach a screenshot ?

Also, one thing I would suggest to do is to actually Log the videoMode width and height to the console, so that you can check the actual resolution:

this can be done using:

int videoWidth = CameraDevice.Instance.VideoModeData.width;

Sorry

I try to make a screenshot but I don't know why with vuforia and android, the quality of the screenshot is too bad.

You should be able to render the view on a restricted viewport (meaning that the surrounding area will be black), by editing the QCARBehavior script, chaging the config.size in the ConfigureVideoBackground() method.

Hello,

I've log the video data : my video width is 720 and video heigth is 480.

I need a resolution 720*1080.

Can I improve the camera instance size to have a good quality ?

Thanks

If the video resolution is 720 x 480, this already indicates a reasonably high resolution for the camera preview (in most devices this is often limited to 640 x 480).

So, I dont think you can reach higher than this.

Ok but the specification of the sony xperia z indicates video recording in 1080p.

There is no solution to get this quality in rendering video with vuforia ?

Thanks

I see your point, but the video recording specifications are not necessarily the same as the preview capabilities of your camera.

OK,

I see.

Is vuforia using the best previexw resolution of the device when I set mode optimize quality ?

Do you know how can I retrive this value on any device ?

Thanks

You can see the actual Camera Preview sizes supported by your device by using installing some "Device Info" apps (you can find many of them in the Google store).
