基于FPGA的星载成像系统设计
Design of satellite-borne imaging system based on FPGA
摘要
Abstract
Since the camera imaging in satellite has high noise and low sensitivity,and is monopolized by foreign coun-tries,a design of spatial camera imaging system based on FPGA and domestic CMOS image sensor is put forward,and applied to the space imaging of small satellites. The domestic high-resolution CMOS image sensor is taken as the imaging component of system. The FPGA of Spartan-6 series is used as the main control chip of system. The image signal output by CMOS is entered into FPGA for catching and sorting,and send to the upper computer through CameraLink interface. The experimental results show that the system can acquire the image with 2048 × 1024 pixels,its SNR (signal-to-noise ratio) is higher than 36 dB, which is better than the reference value of 31 dB provided with CMOS sensor technical manual,the imaging effect is better, and can meet the space imaging requirement of small satellites.关键词
