3.2 The production of a 3D model from the photo taken by 
lower altitude Powered Paraglider 
This time we used what we call Powered Paraglider or 
parachute glider with engine (Figure 8) and took photo with 
digital camera (Figure 9). This type of airplane has advantage in 
that it can take bird view photo safely and with low price and is 
not legally restricted in its flying height. 
The camera we used was Canon EOS Digital SLR type. The 
sensor of Camera is C-MOS type with the size 22.7mm x 
15.1mm, the pixel number 6.5M (3072x2048) and the focal 
length 18mm. The area of the photo we used for modelling was 
100mx50m. 
The analysis we worked out was the following. 
We made orientation on PI-3000 with the control points 
measured by non-prism TS. We measured the building edge and 
foreground with poly-line measurement (both manual and 
automatic DSM: Figure 10(a)). And then we made mesh of the 
plane (Figure 10(b)) and pasted texture (Figure 10(C)). And 
finally we fused all with high altitude aerial photo (Figure 
10(d)).
