Manually change camera exposure settings?

July 14, 2019 - 5:09am #1

Hi, dear Vuforia community.

 

I need to manually control exposure settings like enabling exposure lock and calculate exposure based on a pre defined center area.

CameraDevice.Instance.GetCameraFields() never returns anything for my Android devices and CameraDevice.Instance.SetField() does not seem to work. (Might be because I don't know the correct device keys)

Manually force extended tracking on?

July 14, 2019 - 5:04am #1

Hi, dear Vuforia community.

We use outside image markers which are pretty far away, this makes them prone to jitter and that would be just fine if we could disable tracking of the marker once it is recognized and then switch to rely solely on extended tracking.

So, is there a way to force extended tracking manually whenever we need it?

I don't mind hacking it through reflection or Unity's SendMessage to private methods, or decompiling Vuforia for information to get it working.

Thanks!

User Defined Targetposition game object problem

May 17, 2019 - 12:37pm #1

 HI, 

I'm newbie in Vuforia and I can't understand why my code make properly only one. 

The imageTarget object is taking only once, then I see some paint in scene.

That one painting point is rotate properly with the userImageTarget.

Every next paiting point appear but rotate only with device, independently my userImageTarget,

but the new object paint (represent clone object) have a parent from  imageTarget.

Unfortunately new pait object haven't any parent, I don't know what I should to do.

Camera focus

May 15, 2019 - 2:28am #1

We are developing AR application using vuforia in Unity.

The camera is out of focus and the marker can not be read.

Is there a function that brings the focus of the camera to the position you tap on your smartphone?

What is the Max HD output for vuforia?

April 4, 2019 - 10:26am #1

Hi everyone, I am curious as to what is the max HD output for the Vuforia camera? The device I am testing on has a 4K camera and a 2k screen but it looks very low quality in Vuforia even if I set the quality mode to MODE_OPTIMIZE_QUALITY. I can't quite find the Max specs for Vuforia so if someone could please let me know that would be great.

Detecting objects on streaming video

April 4, 2019 - 8:18am #1

Hi guys!

 

Is it technically possible, to stream the video, and use Vuforia to recognize objects in this streaming video?

The video stream type should be on of RTMP, M3U8, I think.
