# Why you use chessboard? [closed]

Hi dear developers. I found a way to get all camera parameters and rectangle transform and translate from one camera and just one frame with one click. No matrix equations, no quaternion or eulers. It is simple. It is fast. My theoreme: If on the projection of a rectangle we can see the corners and its area is greater than zero, then this rectangle has a representation in space and, moreover, only one. https://www.youtube.com/watch?v=3rX_M... Sorry openCV developers. As it turned out, everything is much simpler.

downvoted for: without looking at the video, -- your post is just blah

people take the truth hard. Thanks for the minus, I spent 3 years of my life on it

if so, why not spend 3 minutes to explain it better,

here?What else needs to be explained? The EQUATION? I Have it.
