Method for extracting container loading bridge based on remote sensing interpretation analysis technology

Abstract

The invention discloses a method for extracting a container loading bridge based on a remote sensing interpretation analysis technology. The method comprises the steps of: firstly, constructing a background model by using LBP texture gray scale invariance; secondly, dividing an image into a plurality of non-overlapping regions according to different characteristics on an initial target model; thirdly, performing topologization and extraction on a remote sensing image, and conducting normalization processing to obtain a shape template; and finally, performing compensation on the shape templateaccording to texture characteristics to identify the container loading bridge. The method is based on fuzzy selection and carries out digitization at the same time, edge information can be maintainedduring the digitization process, the subsequent processing is facilitated, the remote sensing image is divided into the plurality of parts through image segmentation in the processing process, the remote sensing image can be coordinated through normalization processing after compensation of the shape template and the texture characteristics, tremendous amount of computing can be avoided, and the data processing efficiency and identification accuracy rate can be improved.

Description

technical field [0001] The invention relates to the technical field of remote sensing identification, in particular to a method for extracting container loading and unloading bridges based on remote sensing interpretation and analysis technology. Background technique [0002] As an important part of maritime transportation, ports have received more and more attention under the general trend of economic globalization, and the role of containers in ocean transportation is very obvious. The so-called container is a component tool that can be loaded with packaged or unpackaged goods for transportation, and is convenient for loading and unloading with mechanical equipment. In operation, the container loading and unloading bridge is a very important loading tool, which belongs to a new type of auxiliary boarding equipment on the modern industrial loading and unloading platform. [0003] In remote sensing monitoring, it is a current trend to apply remote sensing images to the dete...

Problems solved by technology

[0005] (1) The actual amount of data processing is still very large in the identification of containers through the edge processing method. Therefore, in the remote sensing image, the containers are processed directly based on the edge because the size of the container is too small. In the process of digitization, The amount of calculation will be very huge, which is not convenient for subsequent processing;

[0006] (2) The features of the container loading and unloading bridge are not effectively combined, that is, in the process of identification, a single basic feature is often used, and then another feature is used for verification, and this method is extremely efficient. Low, this is because in the process of extracting the remote sensing suitcase, repeated calculations will lead to a geometric increase in the amount of calculations, and how to comprehensively utilize the identification features is a problem that needs to be solved at present
