6. CONCLUSIONS
This paper proposes a stereoscopic observation system capable
of performing dynamic epipolar rearrangement, which is used
to obtain geographic information from air photography. Briefly
describes the pyramid image generation strategy and methods,
memory pool technology is also involved. The concept of
epipolar rearrangement and the integration operation of the
entire process are investigated deeply. According to the
experiment, a conclusion was drawn that adopt the strategy in
this paper, a high accuracy and precision of stereoscopic
observation can be achieved.
