Embodiment Construction

[0027] The specific implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The main program flow of the UAV image database is to automatically obtain image metadata when entering the database, perform level-based correlation storage and content-based image retrieval, and finally realize the visual display of images.

[0029] A kind of unmanned aerial vehicle reconnaissance image data management and visual display method of the present invention, such as figure 1 As shown, it specifically includes the following steps:

[0030] The first step is to establish a data table based on the metadata of UAV reconnaissance images.

[0031] For higher execution efficiency and convenient and comprehensive retrieval, the UAV image database management method chooses a mixed management method of files and relational databases. Images and image sequence files are stored in the file system, and the file storage p...

Abstract

The invention discloses a UAV reconnaissance image data management and visual display method, which specifically includes the following steps: the first step is to establish a data table based on the metadata of the UAV reconnaissance image; Correlation storage design; the third step, GIS-based image geographic information visualization; the present invention can realize advanced retrieval by entering relevant metadata from the configuration file of the UAV image; the present invention adopts a correlation storage design based on level association , can realize the correlation retrieval for different levels of images stored in the database; the invention adopts the human-computer interaction retrieval based on Google Earth, which can meet the visualization requirements of the geographical information of the UAV reconnaissance image.

Description

technical field [0001] The invention belongs to the technical field of image retrieval, and specifically refers to a method for data management and visual display of unmanned aerial vehicle reconnaissance image data. Background technique [0002] UAV reconnaissance images, as the basic data of UAV reconnaissance, are similar to remote sensing images and have the characteristics of rich content information, large data volume and a large amount of metadata information. A large amount of different data is generated during the integrated processing of UAV reconnaissance images, which requires unified management. Therefore, the data management system is an important link. [0003] In terms of research and application of remote sensing image data management system, the most typical representative software at home and abroad are as follows: [0004] 1)Microsoft TerraServer [0005] Microsoft TerraServer is developed by Microsoft, based on Microsoft SQL Server server, and can be ...
