A Method of Monitoring Port Reclamation Using Remote Sensing Interpretation and Analysis Technology

Abstract

This note discloses a method for monitoring port reclamation by using remote sensing interpretation and analysis technology, which includes the following steps: first assigning gray values ​​to extract fuzzy coastlines; secondly, extracting edge information for remote sensing image smoothing and noise removal in the target area; Furthermore, principal component transformation and principal component inverse transformation are carried out for audio-visual fusion, and the fuzzy boundary line is obtained through direct comparison between the two; finally, correlation statistics are performed to eliminate weakly correlated data to optimize the fuzzy boundary to obtain the change law of the port reclamation range, and through Verify the spatial correlation; based on the gray value assignment and principal component transformation, through the combination optimization of the band and the optimization of the correlation coefficient, the fuzzy boundary is gradually optimized and determined in real time, so as to accurately identify its boundary and determine the actual reclamation Range changes.

Description

technical field [0001] This description relates to the field of remote sensing identification technology, specifically a method for monitoring port reclamation using remote sensing interpretation and analysis technology. Background technique [0002] With the growing demand for coastal land, especially for ports, the land reserve is far from meeting the development needs. In order to solve the tight land demand, in addition to improving the level of intensive use of land resources, land reclamation has become a solution to land The main source of resource scarcity. As practice has proved, scientific and reasonable sea reclamation can minimize the impact on the natural properties of sea areas, but large-scale sea reclamation will still bring a series of ecological problems. Therefore, sea reclamation projects must To carry out the necessary monitoring and control. In the monitoring of land reclamation, the use of remote sensing images is an indispensable and effective way. ...

Problems solved by technology

[0004] (1) Although there are some remote sensing extraction methods for land reclamation from the sea, there is a lack of remote sensing classification system for land reclamation, especially for the existing remote sensing image extraction, the extraction methods are more complicated, and for different Satellite imagery, different sea environment, and different types of land reclamation targets have different extraction rules and different accuracy, so they cannot be processed and compared uniformly in the process of use, resulting in low data utilization and reduced accuracy;

[0005] (2) In remote sensing monitoring, due to the need for real-time or regular update of data, compared with traditional remote sensing recognition, its data processing capacity is very huge. Using direct recognition method, the processing efficiency of remote sensing data is low. It cannot meet the needs of data processing, and in the process of direct recognition, the recognition accuracy is not high due to the existence of interference information, and the use of a single factor such as geometric information or spectral information for detection leads to insufficient information utilization, and Also check the reliability of the results
