specific Embodiment approach 1

[0012] Specific implementation mode 1. Combination figure 1 To illustrate this embodiment, the high-resolution video satellite imaging system mainly consists of two parts: a video imaging unit and a video control unit. The video imaging unit mainly includes optical system, area array CMOS image sensor, FPGA, memory and imaging power supply module; the video control unit mainly includes imaging controller, video compression group, focusing module and control power supply module. The optical system images the ground scene onto the area array CMOS image sensor. The imaging power supply module supplies power to the area array CMOS image sensor, FPGA and memory respectively, and is controlled by the video control unit to output the working voltage that satisfies the overall or rolling shutter working mode of the area array CMOS image sensor. FPGA realizes the register configuration of the area array CMOS image sensor in the global or rolling shutter working mode, generates corresp...

Abstract

A high-resolution video satellite imaging system relates to a video satellite imaging system. The technical problem to be solved by the present invention is the feasibility and reliability of existing high-spatial resolution and large-scale video imaging aerospace applications, including video imaging units And video control unit, video imaging unit comprises optical system, area array CMOS image sensor, FPGA, memory and imaging power supply module, and described imaging power supply module supplies power for area array CMOS image sensor, FPGA and memory respectively; Video control unit comprises imaging control unit device, video compression group, focusing module, and control power supply module, and the control power supply module supplies power to the imaging controller, video compression group, and focusing module respectively; the present invention uses a global shutter working mode to shorten the exposure time interval of the entire frame, reducing the The requirement of attitude stability during the satellite swing process cancels the use of the focal plane image motion compensation mechanism, reduces the volume and reduces the weight, and has no moving parts to improve the reliability of aerospace applications.

Description

technical field [0001] The invention relates to a video satellite imaging system, in particular to a high-resolution and large-width video satellite imaging system with a ground pixel resolution better than 0.5m and a width not lower than 4km×4km. Background technique [0002] Video satellite is a new type of earth observation satellite. Compared with traditional earth observation satellites, its biggest feature is that it can "stare" at a certain area. The so-called "staring" means that with the movement of the satellite, the optical imaging system always keeps an eye on a certain target area, and can continuously observe changes in the field of view. There are two main ways to achieve "staring". One is to use geostationary orbit optical imaging satellites, and the other is to use low-orbit optical imaging satellites with high attitude agility or image motion compensation capabilities. Due to the dynamic characteristics of the orbit, the satellite in geostationary orbit is...
