Camera shaking

By fulviokidloom on Thu, 11/24/2016 - 15:32

Hi guys,

I'm new in Vuforia and I'm working on a project for my company and I'm testing Unity 5 with Vuforia to decide the technology to use.

I have an issue with image target recognition. I can see that my 3d models are shaking.  

When I select the AR Camera it is moving and rotating.. just a little but  it is noticeable

I have tried:

- An Image Target of width 11cm and height 11cm. 

- An Image Target of width 4cm and height 2 cm.

- A VuMark with width of 9cm and height 5cm.

- A VuMark of width 4cm and height 2 cm.

 

With all this targets I have the same issue

 

Anyone have the same issue?

 

Thanks in advance

Hello,

The 3d model 'shakiness' you're observing is due to jitter in the pose returned by Vuforia. The pose is updated approx. 30 times/sec., and each time Vuforia re-calculates the pose based upon the camera image captured.

I was wondering about if there is a best practices for objects (not targets). Currently there is no star rating for .od files, and I couldn't find some kind of general tips on what constitutes a good object model (not image target).

Hello,

With Extended Tracking enabled on HoloLens, you should not see "jumpy" augmentations after the target is detected. After detection and the initial pose is returned by the Vuforia SDK, we will hand tracking off the HoloLens to use its superior spacial tracking system.

I am not sure how superior the spacial tracking system is for a 2x2x2 object. Can we get more details on this? I mean exactly what is happening? Does Vuforia provide a single pixel location (when the object is found), or a full transform?
