本論文提出一套有效量測光滑物體形貌之量測系統，目前的條紋投影輪廓儀，僅適用於漫射效果佳的物體。對於遵守反射定律的光滑物體，則僅有部份表面的反射光，能投射至影像擷取系統而產生影像，其他區域的反射光，因無法成像，而造成部份影像資料的缺失。本研究將條紋圖案呈現在ㄧ平坦平面上，並且置放光滑物體於條紋圖案前，利用面鏡成像的方式，條紋圖案藉由光滑表面產生虛像，其虛像條紋的扭曲程度與物體表面形貌有關，找出其之間關聯性便能還原出其三維形貌。此量測方法除了可以有效量測光滑物體之形貌之外，與傳統條紋投影輪廓儀相同，其優點包含量測簡易以及量測系統構造簡單。

A fringe projection method for specular is presented. For specular objects, only part of the refracted light can be detected by a CCD camera. Thus, the typical projected fringe profilometry cannot be used for specular surfaces. In the proposed method, a fringe pattern is posited in front of the specular surface. A virtual image therefore is produced behind the specular surface. Fringes on the virtual image are deformed by topography of the specular place the object. Thus, phase of the deformed fringes is desirable to retrieve the profile of the specular surface. The measurement setup is simple and robotic, and the computation cost is low. Its one-shot measurement property also makes it possible to inspect dynamic objects.
