A Method of Target Area Filling and Fusion Processing Based on Satellite Remote Sensing Image

Abstract

The invention discloses a target area filling and fusion processing method based on satellite remote sensing images. A target area filling and fusion processing method based on satellite remote sensing images includes the following steps: Step 1: Establishing a sample database; Step 2: Sample pre-processing Processing; Step 3: Replace regional sample filling; Step 4: Boundary fusion; Step 5: Output the image processed by sample filling and boundary fusion into the format of the original target image, and write the corresponding satellite parameter information. This invention hides specific areas with texture samples with certain characteristics and shapes, and solves the problem that when the surrounding environment is complex, the texture of the generated target area does not have certain features of the ground objects and the texture is messy; and the method adopted by the invention It is a region-based replacement method. Compared with the pixel-based generation method, the processing speed is fast and can meet the problem of timeliness.

Description

technical field [0001] The invention relates to the field of remote sensing image processing, in particular to a target area filling and fusion processing method based on satellite remote sensing images. Background technique [0002] With the development of remote sensing technology, the demand for high-resolution remote sensing data in various fields of the national economy is becoming more and more extensive. Government decision-making needs to use high-resolution remote sensing data for resource investigation, disaster relief, and command decision-making. Remote sensing image data has become an important data support for services in land, water conservancy, urban planning, agriculture, environmental protection, and transportation. At present, most of the high-resolution remote sensing data used in the domestic civilian field come from foreign satellite data products. The high price and technical barriers have seriously restricted the development of the space information i...

Problems solved by technology

At present, most of the high-resolution remote sensing data used in the domestic civilian field come from foreign satellite data products. The high price and technical barriers have seriously restricted the development of the space information industry. support

The problem facing domestic remote sensing satellite data for civilian use is: the higher the resolution of the data and the more diverse the types, the more information people can obtain from it, and the more information that needs to be protected is also involved. Once the protected information If it is leaked, it will cause a major threat and immeasurable loss to the safety of the country and people's lives and properties. Therefore, camouflaging or hiding data in sensitive areas is an important prerequisite for civilian use of high-resolution remote sensing images.

[0004] After using the texture generation technology to process the target, the texture of the target is randomly generated by the surrounding texture, so the degree of refinement of the surrounding texture will seriously affect the texture quality of the filled area, and even the phenomenon of disorder will appear, making it impossible to distinguish the ground objects after filling , and this pixel-based calculation method has low processing efficiency and cannot meet the needs of high service timeliness
