Camera Calibration problem

October 28, 2012 - 10:33pm #1

I would like to move 3d model which is triggered by ImageTarget back and forth and make sure the dimension of model on the screen is correct. My thinking is that it will be different on different phone camera because different camera has different parameters, and Vuforia needs to know the camera parameters then the dimension will be correct. Is it correct? Is there possible to set camera calibration parameters for Vuforia? I only see camera calibration api to return the parameters of camera, but how to set parameters of my camera? many thanks~

Hi, brother, i just want to know how to get the parameters of camera through camera calibration api? i cannot find it myself, help please, thanks a lot.

We maintain an extensive portfolio of custom device profiles that define the calibration parameters of their cameras. We obtain these by actually calibrating the device cameras. So the test you describe should produce a consistent result across devices.

Hi allanjjj,

Vuforia does its best to standardise across different cameras so that you should not have to worry about this.

This is one of Vuforias strengths, as basically it will convert this into a pose matrix in a standardised way wherever it finds an augmentation.
