Development of an airborne multi-angle TIR/VNIR imaging system

An airborne multi-angle TIR/VNIR imaging system (AMTIS) is a prototype three-channel multi-angle imaging system. It provides high-resolution data in visible/near infrared and thermal infrared spectral bands for use in deriving geophysical parameters, such as bi-directional reflectance factors. The precision of the viewing angle is decided by the pointing precision of the AMTIS, the status of the airplane such as its pitch angle, roll angle, and heading angle. The illegibility of image caused by movement of airplane is conquered in the AMTIS. The character of the AMTIS will also be described in this paper.
