地面型雷射掃描儀(Terrestrial Laser Scanner, TLS)為一新型測量儀器，利用儀器本身所投射出之可見光束點雲，經由欲測量目標物反射後，藉由儀器接收此反射光來獲得目標物在空間中三維的座標，並分析比較群集點雲參數的大小與差異推估物體所呈現力學狀態，目前TLS於各大測量領域已有相當顯著的貢獻，如：地形邊坡測量、考古以及文化古蹟保護等等。
　　本文針對TLS運用於土木結構桿件變位測量精度之研究，自製三組鋼筋混凝土梁試體，其中三者鋼筋設計皆相同，差異點為混凝土種類的不同，於試體一中採用一般混凝土進行整體試體的製作，在試體二中採用鋼纖維混凝土與一般混凝土進行製作，試體三使用聚乙烯醇纖維混凝土與一般混凝土進行製作，接著對試體進行三點抗彎試驗，試驗其間利用線性可變差動變壓器(LVDT)與TLS對試體的垂直變位進行同步量測，最後利用最小二乘法來分析TLS獲得點雲資料以求得試體變形方程式，並與LVDT測量獲得變形量做比較以求得TLS量測精度。
　　比較以施力點進行分段擬合與材料差異進行分段擬合，依分析成果顯示擬合形式主要受力量加載形式所控制，當材料性質並非有過大差異時，若仍以材料差異進行分段擬合將造成反效果，而TLS運用於結構桿件受力變形量測上，確實有良好的精度表現。

Terrestrial Laser Scanner as a new measurement technology. With TLS can obtain Three- dimensional coordinate point cloud information. In recent years, TLS already has obviously contribution in various field such as archeology, civil engineering, and conserve cultural heritages… etc.
In this thesis, focus on measuring the deformation of structural member by TLS and calculating the precision of TLS measurement. In order to achieve the goal manufacture three reinforced concrete beams as specimens for laboratory tests. Among them the body type and the reinforced design are all the same. But the type of concrete are different from each other. The first specimen is grouted by using normal concrete integrally. The second specimen is grouted by using steel fiber concrete partially. And the third specimen is grouted by using PVA fiber concrete partially. Then carry out three-points bending test after curing of concrete. During the test measure the vertical deformation of specimen by two measuring instruments at the same time. One is Terrestrial Laser Scanner, TLS and another is Linear Variable Differential Transformers, LVDT. Calculating specimen deformation equation with TLS measured point cloud data by least square method. And compare with LVDT’s data in order to acquire the accuracy of TLS’s measurement.
Comparison to segmented fitting base on the point of application and material differences. According to the results, segmented fitting base on material differences is more influential than the point of application. When the material is not too differences between the specimens. The point of application is the better condition to fitting the deformation equation with point cloud data. As well as TLS use on measuring the deformation of structural member dose have good results performance.
