How Vuforia assign camera intrinsic parameter across many different camera devices?

October 21, 2013 - 5:53am #1

Hi, 

I'm creating AR application which allow the real object occlude the virtual object. However, the projection of the real object seems do not match it's current position. I notice this by seeing the relative pose of one target relative to another.

I found  from this thread below how the Vuforia assigned different intrinsic values across many different camera devices

However, the result seems unsatisfied for my application. So, is there any chance to assign our own camera parameter for real scene projection? 

Thanks

Hello,

There currently is no plan to expose the ability to set device camera intrinsic parameters using traditional Engine SDK features while running on embedded cameras.

However, the External Camera feature does expose camera intrinsic control:

Hello,

is there any news ???

I am looking for a shader to undistort videoBackground (with intrinsic and other camera specification...) for IOS and Android.

Working with objects that are far from marker is not accurate at all with any device.

Why is there no explanation and solution at all for this problem !

A 6 years old question and no answer, it seems Vuforia is not able to do this.

If not then it's useless.

did you find it?

Hello,

Can users set their own camera intrinsic parameters for Vuforia SDK v6.0.117 to get more accurate pose ?

 

Thanks

Hi

I'm also interested to know if it is possible to calibrate a specific camera on a specific device (e.g. using checkerboard images) in order to minimize distortion introduced e.g. by the lense. Applying standard calibration data might not be enough for certain applications where higher accuracy is needed.

Thanks,

Lukas

Hi, can you tell the specific device (s) you are seeing this inaccuracy ?

Also, if you have any screenshot, this would help.
