Rocket-borne image acquisition and compression system suitable for sounding rocket

Abstract

The invention relates to a rocket-borne image acquisition and compression method and a system which are suitable for a sounding rocket. The system comprises a power supply management module, several rocket-borne simulation cameras, an image video decoding unit, an image compression unit, a central control unit, a data transmission unit and a watchdog unit, wherein the power supply management module provides power for the whole system; the image video decoding unit is used to carry out digitization on image data of the simulation cameras; the image compression unit is used to carry out wavelet transformation and compression on the image data; the central control unit is used to control the image compression unit and the image video decoding unit, switch among the plurality of cameras and pack and output the image data; the data transmission unit is used to complete buffer and transmission of the image data and convert parallel bus data into synchronous 422 bus data; the watchdog unit is used to monitor software of the whole system. The system is used for realizing image acquisition on the sounding rocket. The system possesses the characteristics that cost is low; power consumption is low; temperature adaptability is good and reliability is high.

Description

Technical field [0001] The invention relates to a rocket-borne image acquisition and compression system, in particular to a rocket-borne image acquisition and compression method and system suitable for sounding rockets. Background technique [0002] Sounding rocket is a kind of rocket for detection and scientific experiment in near-Earth space. Its flying altitude is between the sounding balloon and artificial satellite. It is also the only field detection method in the adjacent space (40~200 kilometers). It is other aircraft. Beyond reach. [0003] Sounding rockets are generally uncontrolled rockets, which have the advantages of simple structure, low cost, short development period, and flexible and convenient launch. It can not only detect the structure, composition and parameters of each layer of the atmosphere in the height direction, and realize the three-dimensional profile detection of the middle and upper atmosphere; it is more suitable for temporary observation of special ...
