Hi,

I want to calculate the 3D world coordinates that correspond to a 2D pixel in the image plane. I know all the rotation and intrinsic/extrinsic parameters of the camera.

Regarding the equations given here
http://opencv.willowgarage.com/documentation/camera_calibration_and_3d_reconstruction.html

I thinl I need to calculate the Vector M in the quation s m = A R M
with
s = scalar factor
m = 3x1
A = 3x3
R = 3x4
M = 4x1

How can I do this in Matlab?

Thanks in advance!!
