hello , i am looking to transform the (u,v) camera coordinates in pixel to (c,y) camera coordinates in mm. using the equations x = u−u0/ku , y = v−v0/kv. : 1/ku the horizontal dimension of the pixel in mm. 1/kv the vertical dimension of the pixel in mm. (u0, v0) the pixel coordinates of the optical axis projection got from intrinsic matrix. i calibrated the camera, and i have the camera intrinsic parameters value. my question is how i can get the focal length and 1/ku from the intrinsic camera ? i'am using a simulated robot with a mounted camera in gazebo ros
