基于线阵CCD扫描的车辆图像采集系统设计

摘要

In order to achieve the image resolution requirements for high-speed vehicle license plate recognition system,we proposed a collection system vehicle images based on linear CCD,and completed a the design of the drive circuit of linear CCD chip.The hardware completes the driver circuit and image acquisition.The software finishes speed compensation for images and USB2.0 firmware design.The experiment verified that this system is easy to operate,the images are highresolution,the design purpose is achieved.%为了实现对车牌识别系统对高速行驶车辆图像分辨率的要求,提出了一种基于线阵CCD扫描的车辆图像系统的方案,完成了对线阵CCD芯片驱动电路的设计.该系统的硬件部分完成对线阵CCD芯片的驱动和图像采集,软件部分完成对图像的速度补偿.经实验验证,该系统具有操作简便、采集图像具有高分辨率的特点,达到了设计目的.
