摘要
介绍了运用在系统可编程逻辑器件和微控制器 ,并充分发挥芯片各自的优点 ,以低成本构成的检测图像水平直线边缘的视频信号处理系统。该系统与步进电机控制系统组成一闭环回路 ,从而实现自动定位功能。生产实践表明 ,本系统有较高的精度和可靠性。
In this paper, a sort of low-cost video signal processing system integrated with in system programmable device and micro-controller was introduced, which can detect horizontal line edge. To implement auto-location function, a stepper motor control system was added to construct a closed-loop system. The result of practice showed that the system has high accuracy and reliability.
