Image simulation and display device for space camera with high resolution and wide coverage

Abstract

The invention relates to an image simulation and display device for a space camera with high resolution and wide coverage, belonging to the field of a space optical remote sensing imaging technology. The invention solves the problems of poor overload function of image data and low transmission rate of an image data source in the existing image simulation and display device for the space camera with high resolution and wide coverage. The device downloads image data into a flash memory via a USB (universal serial bus) interface for nonvolatile storage; a field programmable gate array (FPGA) realizes caching, real-time processing and fusion of the image data as well as interface logic control; and the image data is acquired, stored and displayed after high speed serialization / deserialization. The output image data simulated by the device contains satellite attitude and orbit information and imaging parameters of the camera, and meanwhile, the device accurately simulates the on-orbit operating mode and operating flow of the space camera as well as the output image data, thus providing an effective test means for the research of the space camera with high resolution and wide coverage. The image simulation and display device provided by the invention can be widely applied to the field of the space optical remote sensing imaging technology.
