WebAll questions assume vertical photography 6 inch focal length, 9 x 9 inch format aerial camera, and 60% overlap unless they say different. In some questions you will need to select the answer that is closest to the correct value. 1. What length on the photograph is a 300 ft. line if the flying height is 20000 ft. 2. WebThe parallax of point a and b are Pa and Pb respectively. To represent this parallax, a pseudo-image is drawn at the focal distance of the camera. The parallax of point a and b is Pa and Pb. Pa = xa+ xa’ and Pb = xb+ xb’ Here, the object height measurement depends on the flight height and parallax of top and bottom of the object.
WebJan 1, 1992 · The use of the parallax bar in conjunction with a mirror stereoscope in obtaining object heights using x-parallax measurements on a stereopair of near vertical photography is one of the basic practices in photogrammetry. It has long been acknowledged as a useful and inexpensive heighting technique. WebBureau of Reclamation
