The imaging spectrum technology is one of the foreland research field in the remote sensing development. Its main characteristics are hyperspectral resolution

high spatial resolution

high time resolution and composition of spectrum and image

It has been widely used in the civil economy. Based on analyzing imaging environment of the light aeroplane remote sensing system

this article deeply studied the geometric theory of low altitude remote sensing images. Adopting mathematics modeling method

the author established geometric distortion analysis methods and calibration models

and presents geometric processes. Using the models and software presented in this article

Geometric characteristics analysis and calibration has been carried out for the VIR/SWIR imaging spectrum data

and better processing results are achieved. Furthermore

these results also confirm the practicability of the model.
