Camera calibration algorithm

[appinheiro]

I have some question involving camera calibration process. They are:

1)What algorithm are you using to camera calibration ? Is there any article explaining your camera calibration algorithm ?

2)You tried use the DLT (direct linear transformation) in your system ?


thank you !

Hello,

We use a custom calibration algorithm, and are always working to improve it.

A video of the calibration process is available on the videos page of the OptiTrack website.

Dear,

I need a algorithm name or some reference like a article or home page describing the algorithm. I am engineer and I need judge if this algorithm can be used in my project. So it is very important to know the tecnical features of your algorithm. Just a video dont go help because I want compare your algorithm with the DLT.

Thanks in advance

Hello:

We understand what you are asking, but we consider our calibration algorithm to be a trade secret.

We can say that the "single point wanding process" accounts for lens distortion (including radial distortion), and also the extrinsic camera parameters (where they are in relation to one another). I think it compares very well to DLT.
