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.
