摘要
介绍一种基于单片机控制的CCD镜头自动聚焦控制系统。该系统接收到物体高度信号后,驱动步进电机进行CCD镜头聚焦。为了获得更加清晰的图像,控制系统采用细分技术细分步进电机的步距角,使得CCD镜头调整能够更加精细。
A CCD automatic focusing control system for acquisition of image based on microprocessor is introduced.After receiving the signal of the height of objects, stepping motor for rotating lens will be drived to a suitable location.The more paces the step angle of the stepping motor has been subdivided,the more clear the CCD image is captured.
