tangential distortion and irregularity of scan mirror rotation are
corrected.
In order to utilize the pho tograrnme tr i c principles, an assumed
focal plane( Pl-Pl ) and an assumed principal distance(f) are
introduced as shown in Fig.l. It is supposed that one bundle witii
off-nadir angle (0) is projected on Pl-Pl with photogrammetric
coordinate of (x,y), which corresponds to image coordinate! I pixel,
J line ). Let x direction to be the same as the moving direction of
satellite.
where
x = f•tan £/ cos 9
y = f•tan( 9 + P )
9={I-(N + l)/2}-40 (1)
K = MOD( J - 1, 6 )
i = ( K - 3.5 )■ 40
4 <\$ : IFOV on x direction
A0 : IFOV on y direction
v : angle deviation caused from
the irregularity of scan mirror rotation
N : the number of pixels per line
I : pixel number
K : detector number
Colinearity equation is expressed as below using ground
dinate system ( X,Y,Z ) and rotation angles ( pitch : <f> , row
yaw : K ). I see Fig.2 ]
