光達技術已被應用於各種測量，尤其輕巧型手持式光達之發展最為快速，其中以地形掃描的應用可以達到高效率之目標。手持式光達應用在各工程領域尚屬起步階段，本研究屬超前研究，顯示手持式光達可應用於工程設計、緊急搶救災、現地調查、工程構造物體檢、挖填土方估算等。本研究另探討野溪預鑄護岸推廣應用，協助進行抗水流作用檢算、穩定分析等，並蒐集預鑄塊的施作方法，以及預鑄護岸施工問題整理與建議。

LiDAR technology has been applied to various measurements, especially the lightweight handheld LiDAR has the fastest development, and the application of terrain scanning can achieve the goal of high efficiency. The application of handheld LiDAR in various fields is still in its infancy. This project is an advanced study. The project results show that handheld LiDAR can be used in engineering design, emergency rescue, site survey, engineering structure inspection, estimation of excavation and filling，etc. This research also discusses the promotion and application of the precast concrete block revetment, including calculation of anti-current effects, stability analysis, etc., and collection of construction methods for the precast concrete block，as well as construction problems and suggestions.
