Abstract

The invention discloses a multi-source satellite image real-time online processing technical method and device. The computer network technology, the computer parallel technology, the computer multithreading technology and the image processing technology are comprehensively used for multi-source satellite image real-time online processing. The satellite image processing is fast, the computing resource use efficiency is high, and the data packet throughput rate is large. The multi-source satellite image real-time online processing technical method includes that a data packet is received on a high speed network, and the received data packet is organized to be an image; the organized image data are analyzed, and the analyzed image is subjected to storage format conversion and processing; the processed image data are continued to be compressed; and the compressed image data packet is sent back to the high speed network.

Description

technical field

[0001] The present invention relates to computer network, multithreading, parallelism and image processing technology. Specifically, it is based on computer parallel technology and image processing technology, and is assisted by computer network and multithreading technology to carry out real-time online processing of multi-source satellite images. Background technique

[0002] In computing processing in all walks of life, real-time processing is the general trend, and the most critical technology in real-time processing is computer parallel technology. There are many technologies to achieve computer parallelism, the most important of which are data parallelism and task parallelism. The data parallel technology mainly divides the data into blocks, performs parallel processing according to the blocks, and then merges the block data; the task parallel technology is to execute the original sequence Or different execution sequences are executed at the same time a...

Embodiment Construction

[0030] A specific embodiment of the present invention will now be described in conjunction with the accompanying drawings.

[0031] The flow of the real-time online processing system combined with multi-source satellite images is as follows: figure 1 According to the specific description in "Summary of the Invention", the main steps of the technical solution of the present invention are: data receiving; image processing; image compression; image sending and the implementation of analog sending and receiving software.

[0032] Step A data reception. The system initializes according to the set number of satellite image types. The range of the set satellite type number is [1, 16]. According to the set value, the same number of received satellite image data packet linked lists and package threads are initialized, and different linked lists are initialized. into different threads, where each thread handles a linked list. After initialization, it waits and receives data packets on...
