Design of High Speed and Large Area Array Camera System Based on FPGA
In order to obtain high frame rate and large area array image data,an improved CMOS imaging system based on FPGA is presented.Firstly,characteristic and design method of GSENSE6060 is introduced.Then the hardware design such as the power supply of the imaging system is proposed.Finally,the CMOS image data training algorithm,based on Xilinx Virtex-5 FPGA is emphatically studied to ensure the accuracy of data acquisition.Experimental results proved that at the resolution of 6 144 pixel×6 144 pixel,the frame frequency of the designed imaging system reaches 20 frame/s,the peak data rate is 16 Gbit/s,and the readout noise is better than 4e-.At present,the system is successfully used in the camera system,the perfect restoration quality and effectiveness meets the require-ment of system design.
