Correction of Heights from Parallax-bar Using Finite Element Approach

The finite element approach has been used to correct heights obtained from parallax bar measurements and conventional parallax-height formula based on vertical aerial photography. Experimental tests show that this approach could give higher accuracy than the conventional second degree polynomial cor...
