摘要

在本論文研究中，我們使用普通且低成本的光流計(optical flow sensor)作為圖像處理的核心，採用了一組帶有經由圖案設計的標籤貼紙與圓盤作為圓盤形讀取器，將角度變化（旋轉）轉換為線性運動(直線)。便可以使用較低成本的傳感器獲得角度變化，因此，可以顯著降低光學角度編碼器內部的光柵的製造成本，使角度傳感器可以在各種設計中更廣泛和普遍地使用。

In this study, we used the common and low-cost optical flow sensor as the core of image processing. We simply adopted a set of designed discs with pattern sticker on it as a checkerboard disk to transfer the angle variation (rotation) to a linear motion. Angle variation is obtained using lower cost sensors. Therefore, significantly reduction of the manufacturing cost of the grating, which is inside the optical angle encoder could be made. Angle sensors can be used more widely and universally in a wide variety of designs in the foreseeable future.
