My final Year Project is 3d Motion Capture. I am using 3 cameras arranged in a triangular position. (Due to this triangular placement, the coordinate system of all the cameras will be different) Let me try to elaborate my Project. A number of markers will be attached on the joints of a person. He'll perform some motion in front of cameras and his motion will be ‘mapped’ to some character in OpenGL.
The first step in capturing motion is the calibration of cameras, after which we get the intrinsic and extrinsic parameters of the camera. We are calibrating the cameras with the help of Zhang Calibration Technique <http://research.microsoft.com/~zhang/calib/ >All is well up to this point. I am a bit confused about the next step. What will I do with these intrinsic and extrinsic parameters? My presumption is that I apply the respective rotations & translations (extrinsic parameters) on the images gathered from these cameras. This will result in all the three cameras in the same coordinate systems. I have looked into a lot of papers but cannot find any thing that supports my presumption.
Kindly bail me out.
