camera extrinsics

The rotation and translation describing where a camera is and which way it's pointed in the world.

A camera's extrinsics are the rotation matrix R and translation vector \mathbf{t} that place the camera's own coordinate frame within a world coordinate frame -- where the camera is and which way it's pointed. Extrinsics change every time the camera moves, unlike intrinsics, which describe the camera itself.

Examples

  • Moving a tripod-mounted camera three feet to the left changes R and \mathbf{t} but leaves the camera's own intrinsics completely untouched.
