public interface P3PLineDistance
A related problem to the full P3P problem is to estimate the distance between the camera center and each of the 3 points being viewed. Once those distances are known the full 3D rigid body transform can be computed.
More formally states the problem is: Three points (P1,P2,P3) in 3D space are observed in the image plane in normalized image coordinates (obs1,obs2,obs3). The distance in 3D space between pairs of points (P1,P3), (P1,P2), and (P2,P3) is known. Solve for the distance between the camera's origin and each of the three points.
