The real-time processing platform mainly comprises an image acquisition module, an image preprocessing module and a remote sensing image core processing module, wherein the image acquisition module consists of a fiber coupling sensor and a Cmos image sensor; the image preprocessing module consists of a field programmable gate array (FPGA) chip, an SRAM memory and a Flash memory, and the SRAM memory and the Flash memory are connected on the FPGA chip; and the remote sensing image core processing module consists of a digital signal microprocessor (DSP) chip, a high-speed SDRAM memory and a Flash memory, and the high-speed SDRAM memory and the Flash memory are connected on the DSP chip. The invention supports high resolution images; because of high integrated level control, the effectiveness and instantaneity of the system are greatly improved; the hardware adopted by the invention has simple and flexible framework and stronger generality, and is suitable for modular design, thereby being capable of improving the efficiency of the algorithm; and simultaneously, the invention has short development period and the system which is easy to be maintained and expanded, and is specially suitable for high-speed real-time image signal processing.

Description

Technical field: [0001] The invention relates to a remote sensing image real-time processing platform, in particular to a remote sensing image processing platform capable of real-time collection and processing of high-resolution remote sensing images. Background technique: [0002] At present, in the existing remote sensing image real-time processing platform, there are not many scanning imaging systems that can support higher resolution, not only that, but can support ultra-high resolution remote sensing images with more than 6000 pixels in one dimension The real-time processing platform is even rarer, almost no such type of product has been found in China. [0003] Most of the existing remote sensing image processing platforms and photographic equipment (remote sensors) are relatively independent two sets of equipment, so the remote sensing image processing platform cannot perform effective real-time monitoring of photographic equipment (such as exposure, gain, etc.) cont...
