6. CONCLUSION 
The key technique producing orthpoimage from RSIHR 
includes the parameter computation of RSIHR, image matching 
creating DTM and fast orthogonal rectification of 
RSIHR.The parameter computation of RSIHR can be based on 
two ways. One is the block adjustment with RPC/RPB 
parameters for IKONOS and QUICKBIRD images, which 
needs less control points. The other is the new strict geometric 
model based on affine transformation for any RSIPHR, which KE 
needs more than five control points per image. The accuracy of 
ABS 
both methods can reach to the level corresponding to the ground 
llax is remained in the 
to 
resolution of the image.Quite large y-para 
approximate epipolar image pair of some RSIHR after relative 
registration. 2-D relaxation matching, based on feature points, Qui 
can overcome the disadvantage in the DTM Modelling from geor 
RSIHR. Bef 
beer 
The block adjustment of the new strict geometric model based whic 
t Fron 
diffe 
on affine transformation for any RSIPHR is the farther research 
resti 
work to reduce the number of control points.
