摘　　要：针对CCD传感器IL-P3-B具有高实时性、高分辨率及低噪声的优点,设计了一款基于FPGA的工业检测相机。分析了一种基于FPGA的CCD驱动电路结构,给出了驱动时序的QuartusⅡ仿真及其实测波形图。研究了基于FPGA的图像并行校正算法与处理方法。实验结果表明,以FPGA为核心的驱动电路能够产生符合CCD要求的驱动信号;图像经FPGA校正算法处理后,可以提高图像质量。An industrial inspection camera was designed, based on the advantages of the CCD sensor IL-P3-B, such as high real time, high resolution and low noise. The structure of driving circuits based on FPGA was analyzed. The waveforms of timing-driven in the Quartus Ⅱ simulation and the actual measurement were presented. In addition, an algorithm of calibrating image based on FPGA was researched. Experiments indicate that the signals which are generated by driving circuits based on FPGA as the key circuit meet the requirements of CCD, and that the quality of image can be improved after calibration in FPGA.
