# calibration board tracking

Hi all,

I know the x, y, z values of all the points on this calibration board very precisely. I want to calculate a homography between the found pixel locations of the large dots, and their corresponding x, y, values. Then I can map the image, so the dots are in nicely arranged rows and columns, so then I can determine what row/column each dot is on.

Does anyone have any tricks / tips on how to determine the correspondence between the found large dot pixel u,v location and their known x,y locations?

Thank you!
