摘要

本文以二部攝影機及二部步進馬達組成雙眼立體視覺影像追蹤系統。雙攝影機連續擷取移動目標物的成對影像，經由影像處理方法，求出移動目標物的中心與左右影像中心之水平及垂直距離。並且，經由本文設計的模糊控制器將影像資訊轉換成馬達致動訊號，帶動攝影機即時追蹤移動目標物。

In this paper, we design an image tracking system which is composed of two cameras and two stepping motors. First, The image pair of a moving target is grabbed by two cameras continuously. The horizontal and vertical distances between both centers of this moving target and the image can be determined by using image processing methods. Furthermore, a fuzzy logic controller pair is designed to convert images information into motor actuating signals which control the image tracking system to track the moving target in real time.
