APPLICATION OF BALLOON PHOTOGRAPHS TO THREE 
DIMENSIONAL MEASUREMENT 
DANS 
Fig. 5 is a stereo pair which was taken from 
a kite balloon of altitude of 800 meters. In this 
island 8 control points were established. 
The results of interior orientation parameters 
shown in Table 2 were adopted to the orientation 
and three dimensional measurement. 
Table 4 shows the accuracy of exterior 
orientation, and the accuracy of three dimensional 
measurement for control points. Those resluts 
show that three dimensional measurement can be 
done in permittable accuracy by a kite balloon- 
non metric camera system.

FUTURE PLAN IN A KITE BALLOON SYSTEM 
To solve the disadvantage on a kite balloon 
camera system that whether an appropriate scene 
can be taken or not, is not made sure in advance, 
a TV camera connected with fiber cable to TV 
monitor and video recorder on the ground is now 
under development by the authors. (see Fig. 6) 
The TV camera will be rotated and titled by 
a command through the fiber cable. 
Only when an appropriate scene can be seen in 
the monitor, a film will be photographed by radio 
control shutter or fiber cable signal.

CONCLUSION 
A kite balloon borne camera system is useful 
for small area's photogrammetry and remote sensing. 
The biggest advantage of the system is the 
possibility of easy operation by any amateur. 
In future, a TV camera and/or an infrared 
eye camera will be able to be installed with 
fiber cable communication system, which will 
extend the remote sensing capabilities.
