Uniqueness of 3D Pose Under Weak Perspective: A Geometrical Proof
December 1995 (vol. 17 no. 12)
pp. 1220-1221

Abstract—We present a purely geometrical proof that under the weak perspective model, the 3D pose of a 3-point configuration is determined uniquely up to a reflection by its 2D projection.
