摘要
为了对激光光斑图像进行采集和计算机处理,文章给出了一种基于USB2.0接口的图像重心测量系统的设计方案。该方案利用CCD(Charge Coupled Device,电荷藕合器件)做为图像传感器件,以CPLD(complex programmable logic device,复杂可编程逻辑器件)为控制核心,通过USB2.0与计算机实现接口,从而实现了光斑图像的实时采集,最后利用重心法计算出图像的重心。试验证明本系统能快速实时的对光斑图像进行采集和重心测量。
In order to acquire and process the image of laser facula with computer, this paper presented a method to design an image barycenter measurement system based on USB 2.0. Using CCD as image sensor and CPLD as control center ,this system solved realtime image sampling by exchanging data with computer through USB2.0 port.At last the barycenter of laser facula was calculated using barycenter measurement method. Experiment results indicated that this system can do real-time image data acquisition and barycenter measurement.
