Embodiment Construction

[0039] In order to better illustrate the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] Such as figure 1 A method for generating and real-time deployment of remote sensing image tiles is shown, using a pyramid model and an image processing algorithm to slice image data, including the following steps:

[0041] Step 1, analyze the command line, determine the configuration parameter analysis method, and obtain the tile configuration parameters. The parsing methods include static mode and dynamic mode. The static mode reads the XML file of the specified path, and the dynamic mode parses the command line parameters when calling the program;

[0042] Step 2, create a log file, check various configuration parameters, and if a certain configuration parameter is empty, the program exits. Including image path, coordinate system type, tile specification, tile format, etc.;

Abstract

The invention relates to a method for generating and real-time deploying remote sensing image tiles, comprising the following steps: parsing a command line, obtaining tile configuration parameters; creating a log file, checking configuration parameters; obtaining running computer hardware information, creating a thread pool; determining Tile slicing standard, obtain image parameters, calculate the maximum and minimum level of the image; according to the hardware information of the running computer, dynamically divide the remote sensing image into blocks, traverse each image, import the block image into the memory, and calculate the minimum level of the block image And the maximum level and affine transformation parameters; traverse each level, perform tile index encoding; thread pool slices in parallel; after each level of tile is processed, the current block slice ends; after each block of image is processed, the slice ends. The invention has fast slicing speed and high efficiency, and can not only send data through the network and save it to the server, but also save it locally.

Description

technical field [0001] The invention belongs to the technical field of image slicing, in particular to a method for generating and deploying remote sensing image tiles in real time. Background technique [0002] Currently, slicing is an important function in Web GIS. However, with the growth of image data and the increase of image size, the real-time performance of network geographic information system is facing challenges, and the speed of image slicing seriously affects the use of network geographic information system. At the same time, when performing image slicing, the boundary tiles only exist in some areas, but currently there are relatively few processing methods for boundary tiles. [0003] At present, how to achieve efficient slicing of image data, how to realize ultra-large-size image slicing, and how to realize tile processing in some areas of image boundaries have become urgent problems to be solved. Currently, there are two commonly used slicing methods. One i...
