Photogrammetry

Photogrammetry is a technology of taking measurements of physical objects present in the environment, using photographs. It includes the process of recording and analyzing a three-dimension image in the two-dimension form. Photogrammetry was invented around 150 years ago in 1851 by Aimé Laussedat, he was also known as the father of photogrammetry, but this method was not in use until 50 years after its invention. This method was first used in Germany by Dr. Albrecht Meydenbauer in 1893 who was the director of the Royal Prussian Photogrammetric institute founded by him.

A vertical photograph of a flat area having an average elevation of 250 metres above mean see level was taken with a camera having a focal length of 20 cm. A section line AB, 250 m long in the area, measures 8.50 cm on the photograph. A tower in the area also appears on the photograph. The distance between the images of top and bottom of tower measures 0.46 cm on the photograph. The distance of the image of the top of the tower from principal axis is 6.46 cm. Determine height of the tower.
