基于CCD摄像的视觉跟踪误差信号提取

Extraction of Error Signals for Visual Tracking Based on CCD Video Camera Imaging

介绍由纯硬件电路实现基于CCD摄像的视觉跟踪误差信号的提取,能实时给出精度较高的跟踪误差电压 信号(侧向偏差d2走向偏差tgθ)。并给出电路原理图和测量数据。

This paper discusses the realization of error signal extraction for CCD-video-camera-imaging-based visual tracking via a hardware circuit, which is capablc of providing tracking error voltage signals （lateral deviation d2 and bcaring deviation tgθ） to a high accuracy. The rclevant circuit diagram and measurcment data are also provided.
