3) A vertical aerial image is photographed using a camera has an angle of view equal 100 degrees. Three points appear in that image which are A, B and C. Points A and B are the top and the bottom of a tower. The ground distance of BC equals to 3395.4 meters. The principle distance to point (a) on the top of the tower is 80.32 mm as measured on the image by a micro ruler. The image format is : 230 x 230 mm. image coordinates (mm) Elevation Point (m) x- coordinate y- coordinate 50.31 52.71 75.33 68.78 Determine the focal length of the used camera. Compute the flaying height above see level. Determine the tower height (AB).
