Embodiment Construction

[0044] Referring to the accompanying drawings, the imaging spectrum data processing system and data processing method of the present invention will be described in detail below.

[0045] figure 1 The imaging spectrum data processing system of the present invention is schematically shown, which includes an input module for inputting raw image data according to an airborne imaging spectrometer, such as OMIS-I, HyMap, etc.

[0046] The imaging spectrum data processing system of the present invention also includes a preprocessing module, which is used to obtain the corresponding 0-level, 1-level, and level 2 data products, the preprocessing module further includes:

[0047] The format conversion module is used to convert the original data format into a format that the system can handle. Due to the existence of a variety of imaging spectroscopy instruments, the data formats formed by them are different, and the information of many platforms is also saved. In order to facilitate t...

Abstract

This invention provides an imaging spectroscopic data processing system and method, based on present status that there exists no mature system in imaging spectroscopic data processing realm capable of pre-processing data, intending by format-switch processing original data input to the said system, radiation scaling data according to equipment parameter, atmospheric correcting the data scaled, geometric correcting the data by attitude parameter, rebuilding spectrum by surface-scaling data and so on to realize the treatment of imaging spectroscopic data and automatic pre-processing of imaging spectroscopic data via computer technology. The invention improves appliance efficiency and effect of imaging spectroscopic data treatment, and promotes appliance industrialization progress of airborne imaging spectrum technology.

Description

technical field [0001] The present invention relates to imaging spectrum technology, and further relates to an imaging spectrum data processing system and processing method. Background technique [0002] Imaging spectroscopy is one of the frontier technologies in Earth observation. The rise and rapid development of imaging spectroscopy technology has not only greatly enhanced the ability of remote sensing to observe the earth and identify the ground features, but also promoted the development of remote sensing from the identification of ground features to the direct detection of ground features or the components of ground features. identify. [0003] Since the development of imaging spectroscopy in the early 1980s, especially in the investigation and evaluation of geological and mineral resources, remote sensing technology has the ability to directly identify and extract the composition and structure information of rocks and minerals, making remote sensing quantitative rese...
