Abstract

An automatic production system suitable for high-resolution remote sensing image advanced products relates to the technical field of optical remote sensing image processing, solves the problem of an existing efficient automatic processing system requiring remote sensing images, and comprises an image orthographic module, an image registration module, an image fusion module, an image stretching module and an image enhancement module. The image orthographic module adopts an orthographic correction method of an RPC model fused with image space compensation; the image registration module is used for registering the orthographically corrected multispectral image by taking the orthographically corrected panchromatic image as a reference; and the image fusion module fuses the registered images byadopting an adaptive Gaussian filter SFIM fusion algorithm, and the image stretching module stretches the fused images; and the image enhancement module performs color enhancement on the stretched images by adopting a Frankle-McCann method. According to the automatic production system suitable for high-resolution remote sensing image advanced products, high-efficiency automatic processing of high-resolution remote sensing image advanced products is realized, and the automatic processing level and precision of remote sensing satellite data are high.

Description

technical field [0001] The invention relates to the technical field of optical remote sensing image processing, in particular to an automatic production system for advanced products of high-resolution remote sensing images. Background technique [0002] In recent years, domestic commercial remote sensing satellite constellations represented by the "Jilin No. 1" satellite constellation have been continuously launched. The construction of satellite constellations has brought massive remote sensing data. Massive remote sensing data needs to be processed quickly, otherwise its value will be greatly reduced. Traditional processing systems / methods generally use commercial software, such as ENVI, ARCMAP, PCI, etc., which require a lot of manual intervention and step-by-step processing. The efficiency is extremely low and cannot meet the needs of rapid response. Batch automated processing is the only way out. However, at present, the automatic processing level of domestic remote sen...
