III)RozwiÄ…zanie :
a)wysokość lotu W/H
$\ \frac{1}{m} = \frac{f}{W}$ ; $\frac{1}{9000} = \frac{0,015m}{W}$ ; W = 9000 × 0, 015m = 135m
b1)baza podłużna Bx
$B_{x} = \frac{m \times d_{x} \times (100\% - p)}{100\%}\ ;\ B_{x} = \frac{9000 \times 0,23m \times (100\% - 80\%)}{100\%} = \frac{2070m \times 20\%}{100\%} = 414m$
b2)baza poprzeczna By
$$B_{y} = \frac{m \times d_{y} \times (100\% - q)}{100\%}\ ;\ B_{x} = \frac{9000 \times 0,23m \times (100\% - 30\%)}{100\%} = \frac{2070m \times 70\%}{100\%} = 1449m$$
c)zasięg zdjęcia Dx ,  Dy
Dx =  dx × m ;  Dx = 0, 23m × 9000 = 2070m
Dy = dy × m ;  Dy = 0, 23m × 9000 = 2070m
d)zakładka Z
Z = 0, 1 × Dy ; Z=0,1×2070m=207m
e)powierzchnia modelu stereoskopowego Pm
Pm = (Dx−Bx) × Dy ;  Pm = (2070m−414m) × 2070m = 3427920m2 ≈ 3, 429km2
f)powierzchnia dodana przez każde zdjęcie Pn
Pn = Bx × By ;  Pn = 414m × 1449m = 599886m2 ≈ 0, 599km2
g)liczba zdjęć NZ
$N_{Z_{C}} = N_{Z_{S}} \times N_{S}\ ;\ N_{Z_{S}} = \frac{L_{S}}{B_{x}} + 5\ ;\ N_{S} = \frac{L_{y}}{B_{y}}\ ;\left\lbrack L_{s} = D_{x}\ ;\ L_{y} = D_{y} \right\rbrack\ ;\ N_{Z_{C}} = (\frac{D_{x}}{B_{x}} + 5) \times \frac{D_{y}}{B_{y}}$
$N_{Z_{C}} = \left( \frac{2070m}{414m} + 5 \right) \times \frac{2070m}{1449m} = 10 \times 1,42 = 14,2 \approx 14\ zdjec$
h)interwał fotografowania t
$t = \frac{B_{x}}{V}\ ;\ t = \frac{414m}{300\frac{\text{km}}{h}} = 414m \times \frac{3600s}{300000m} = 4,968s \approx 4,97s$
$t = \frac{d_{x} \times m}{V} \times \frac{100\% - p}{100\%}\ ;\ t = \frac{0,23m \times 9000}{300\frac{\text{km}}{h}} \times \frac{100\% - 80\%}{100\%} = 2070m \times \frac{3600s}{300000m} \times \frac{20\%}{100\%} = \frac{7452}{1500}s = 4,968s \approx 4,97s$
i)rozmazanie obrazu sÂ
$s = V \times t \times \frac{f}{W}\ ;\ s = \frac{300000m}{3600s} \times \frac{1}{125}s \times \frac{0,015m}{135m} = \frac{45}{607500}m = 0,00007407m = 0,074\text{mm}$
$s = \frac{V \times t}{m}\ ;\ s = \frac{\frac{300000m}{3600s} \times \frac{1}{125}s}{9000} = \frac{30}{45}m \times \frac{1}{9000} = 0,00007407m = 0,074mm$
