Question

A tilted photograph is obtained with a camera with a focal length equal to 6in (152.4mm) from a flight height above the Datum equal to 8,200ft. The tilt angle is 2˚30 ’and the swing angle is 218˚. Point A has an elevation above the datum equal to 1,435ft and point B has an elevation above the datum equal to 1,587ft. The photo coordinates in A are as follows are in x equal to -2.85in and in y equal to 3.43in. The photo coordinates in B are as follows are in x equal to 3.89in and in y equal to -1.78in. Calculate the Earth coordinates of points A and B and the Earth length AB.

Answer #1

A photograph was taken from an
altitude of 1700.0 m. above datum. If the average elevation of the
project area is 250.0 m above datum, and the focal length of the
camera is 208.90 mm.,
What is the ground coverage if the format of the photograph is
23.0 cm x 23.0 cm?
If the percentage end lap is 65%, what is the ground area (in
sq. meters) of the end lap?
What was the air base?
If the aircraft flew...

1). Object height estimation from a single vertical
aerial photograph
The relief displacement of the top of a tower is 5 mm and the
distance from the displaced point to the principal point of the
photo is 130 mm.
a) knowing that the focal length of the
camera used is 150 mm and the scale of the photograph is 1:12 000,
calculate the height of the tower.
b) based on the calculated actual height
of the tower in a), if...

In order for a film camera with a fixed focal length F to focus
on anobject located a distance x from the lens, the lens must be a
distance yfrom the film. F, y, and x are related as follows:
Now suppose a camera has a lens with focal length F = 65.
Explain what happens to the distance between the lens and the
film as the object moves far away from the lens. When an object far
away (x...

6.) A light ray traveling in air, n = 1.0, is incident (angle of
incidence = 45 o ) upon a boundary with another medium,
n = 1.2, therefore, the light ray transmitted into the second
medium is refracted as follows;
a.) transmission angle is less than 45
o
b.) transmission angle is equal to 45
o
c.) transmission angle is greater than 45
o
d.) transmission angle is unknowable
Answer__________
