基于FPGA的高速彩色线阵CCD实时图像采集系统

High Speed and Color Linear CCD Real-time Image Acquisition System Based on FPGA

文中设计了一款彩色线阵CCD实时图像采集系统,选用FPGA作为主控芯片。该系统完成了线阵CCD传感器、模数转换芯片的驱动、数据采集与转换。转换后的数据通过FPGA预处理后,由USB2.0传输至上位机实现图像实时成像。结果表明:设计的彩色线阵CCD实时图像采集系统能够满足工业应用要求,每行像素点达2 098个,行频可达9 000 fps。

The color linear CCD real-time image acquisition system was designed in this paper. The system chose FPGA to be the master chip.The system completed the driver of linear CCD sensor and analog-digital conversion chip, data acquisition and conversion. The transformed data after pretreatment by FPGA Was transmitted to the computer for real-time imaging by the USB 2.0. The results show that the design of color linear CCD real-time image acquisition system can meet the requirements of industrial application , the pixel resolution of the system is 2 098 and the line frequency can reach 8 000 fps.
