摘　　要：通过与传统位移传感器反馈控制系统进行比较研究图像处理反馈控制系统的可行性与可靠性.实验结果显示在图像采集帧速率为25fps,运动目标速度、加速度变化的情况下,图像反馈控制实时响应较快,伺服控制电机跟踪平稳,控制可实现.得到位移曲线对比图,进一步在分辨率、峰峰值和周期等方面对两种控制跟踪位移曲线进行对比分析,数据表现出较好的吻合性,表明基于图像反馈实时控制系统控制可靠,能够达到传统位移传感器反馈控制系统的控制要求和控制效果,得出了基于图像特征识别实时反馈控制,可以应用在一些工业实时反馈控制领域的结论.With the conventional displacement sensor feedback control system compares to study the feasibility and reliability of image processing feedback control system. The results showed that in the image acquisition frame rate of 25 fps, the moving target speed, acceleration changing circumstances, the image feedback control system has fast real-time response, servo motor tracked smoothly, control can be achieved. Got the curve comparison chart, and analyzed the two-cycle control tracking curve in further aspect of the resolution, peak to peak, and cycle. Data showed good agreement, indicated that the image feedback control system was reliable, which could achieve the control requirements and control effects of traditional displacement sensor feedback control system. The conclusion is drawn that image feature recognition based real-time control can be applied in industrial real-time feedback control field.
