Abstract

The invention discloses a rapid slicing method and system for a multi-scale mass remote sensing image. The method comprises the following steps: S1, receiving and storing an image data file; S2, carrying out task partitioning calculation on the image data, and carrying out tile segmentation and layering on the image data; And S3, constructing a pyramid rapid indexing system of the image data according to the calculation result in the step S2. According to the invention, the multi-scale image data is subjected to slicing, storage and service publication by establishing a rapid indexing mechanism; and rapid query and application of the image data are realized, so that the problems of time consumption, bottleneck in IO efficiency, unrecoverable program processing abnormity and inconvenience in service migration when the large image data is loaded from the disk in the traditional mode are solved, the data processing efficiency and throughput are enhanced, and the user experience and the actual application value of the image are improved.

Description

technical field [0001] The invention relates to visual processing, in particular to a fast slicing method and system for multi-scale massive remote sensing images. Background technique [0002] With the development of computer technology and network, geographic information system came into being, which caused a major change in GIS technology. The biggest advantage of GIS lies in the current situation of its spatial database, and with the development of GIS technology, the advantage of this feature becomes more prominent. Remote sensing images are one of the important data sources of geographic information systems, through which remote sensing images can quickly and continuously capture large-area, continuous and comprehensive geographic information. Space remote sensing technology can provide periodic observation results and provide more dynamic information for GIS. The remote sensing satellite data application industry supports my country's technological development and i...
