Moreover, pose angles of the plates and the dihedra inside a building are easily known if we have obtained the pose angles of the interior trihedra. This paper intends to develop an effective method to estimate the pose angle of the trihedral.
With the capability of determining the pose angles of all the trihedra appearing in an image, it has overcome the constraints of the echo-domain method.
But in a man-made building, there are often many trihedra. Consequently, the echo-domain based method is of no effect.
The left and right wall-wall-floor trihedra are very weak when the transmitter is located at (0, 0.8m) and (0, 2.8m), respectively.
