摘　　要：三维坐标测量是测量中的一个重要分支,被广泛用于工业、军事、科研等许多领域。位置敏感器(PSD)具有体积小、灵敏度高、线形范围大、响应速度快等优点。三角测量法原理简单、计算方便,在无接触测量距离及面形中有相当重要的实用价值。本文以三角测量法为基础,利用PSD作为探测器,实现对目标的三维坐标测量。Absrtact: The 3D measurement is an important branch of measurement, which is widely used in the fields of industry, military affairs, scientific research and etc. Position Sensible Detector (PSD) possesses small size, high sensitivity, big linear range and rapid respond speed. Triangle measuring method has quite important practical value in non-contact measurement for distance and three dimension position of surface, and its principle is simple and calculation is convenient. Based on triangle measuring method, using PSD and Triangle measuring method in 3D-coordinate measurement of object is introduced.
