  It would require to install the sdk and use ladybugGetCameraUnitFocalLength() and ladybugGetCameraUnitImageCente() public member function of Ladybug API to get the focal length and image center in pixel unit. With this function, user could specify the actual camera number to retrieve this value either directly from camera or stream file.
