A Dynamic Target Imaging System Based on Reflector Splicing
With the interline transfer area-array CCD KAI-01050 as the image sensor,a dynamic target imaging system based on a reflector splicing structure was designed.The CCD timing control and driving circuits were designed,and the related noise in video signal was eliminated by correlated double sampling(CDS).By analyzing the reason for image degradation in the central FOV of reflector splicing,a mathematics model for image restoration was established,to restore the image in the central FOV of reflector splicing.With FPGA as the core control device,the whole system adopted a ping-pong buffer structure for high-speed parallel processing of the image data.The system delay satisfies the requirement of dynamic target imaging.After restoration,the SNR for image in the central FOV is improved by 14.8 dB.
