Apparatus for partitioning compressed satellite image and the method thereof

摘要

Disclosed an apparatus and method of partitioning compressed satellite image, and more specifically, the present invention relates to a technique for forming index information on the compressed satellite image using the starting point and the length of a compressed section so as to randomly access each compressed section in the wavelet-based compressed satellite image recommended through CCSDS. The present invention minimizes costs for long-term storage of the satellite image data by immediately indexing, partitioning, and storing the compressed satellite data in a storage without recovering the compressed satellite data, rapidly provides high-quality satellite images for users by minimizing information loss while recovering the compressed image, and thereby being effective for being able to reduce computing resources needed to recover the compressed image data.

主权项

1. An apparatus having a processor for partitioned processing of compressed satellite images, wherein the processor causes the apparatus to:
receive, using the processor, a source packet including high resolution wavelet transformed compressed satellite image segments continuously transmitted from satellites; extract, using the processor, compressed satellite image segments and length information of the high resolution wavelet transformed compressed satellite image segments from the received source packet; generate, using the processor, an index of the compressed satellite image segments using the length information and a consecutive beginning position; and store, in a storage unit, the compressed satellite image segments and the generated index.
