Although Airborne MSS imagery have spectral resolution owning eleven bands at most and spatial resolution within three to ten meter , the geometric correction of an imagery become complex and hard , in terms of the unstable aerial sailing , up to 89.52° of FOV and panoramic distortion.
The research provides the approach used to deal with the Airborne MSS imagery’s geometric correction with a mathematical model—Rational Function Model (RFM) that can correct imagery simply , quickly ,and accurately . The RFM needs numbers of control points for geometric correction . Selecting numbers of control points is time-comsuming and labored . In the research , imagery feature selecting method and pixel matching method pick up numerous and uniform control points that contain DTM information automatically, then imagery geometric correction set out to use RFM.
The research results explain that any terrain relief of a small range imagery using RFM’s high order model for geometric correct could reach 2 pixel accuracy ,and It is within 3 pixel accuracy in the large range imagery . If in spite of terrain relief , a small range imagery using RFM’s high order model for geometric correction is good , and it depends on terrain relief in a large rage imagery. The accuracy is about 3 pixel.The results demonstrate that the research approach provide a fast and automatic geometric correct method for
Airborne MSS imagery. |
