Distance from an object.. Where is the camera origine?
I compute the distance from an object (Chessboard) using OpenCv and my camera parameters using those steps:
findChessboardCorners
solvePnP
->Distance
The distance I get is between two points: the chessboard and the camera. My question is where is the origine of my camera?
I know perfectly about my Chessboard but not my camera in terms of reference.
As far as I understand camera calibration, the camera origin is on the focal point, which is the projection center. This topic has nice figure illustrating this. So my guess is that the distance is between the object point (your pattern position) and the projection center. @Tetragramm has the necessary experience to confirm this I guess.
