結合多星系快速精密定位與3D LiDAR技術應用於3D立體地圖之建置

A Study on 3D Stereo Map using Multi-Satellite Measurement and 3D LiDAR technology

現今三維雷射掃描儀技術發展迅速，吾人構思若是圖根點不在地面上，而是設置於門牌或是屋簷等空中不易受損之位置，相信如此下來，未來土地複丈作業必能減少諸多不便。本研究依據下列幾個研究目的進行實驗：1.測試新興設備應用於內政部國土測繪中心推廣之電子化全球衛星即時動態定位系統（e-GNSS）；2.結合多星系快速精密定位與三維光達雷射掃描技術，充分實施“圖根點不落地”之概念；3.利用上述成果建置三維立體地圖。經本實驗數據分析，佈設之3個地面控制點及15個圖根控制點，平面位置較差值皆在0.006～0.052m之間，完全符合地籍測量實施規則最大誤差2～6cm內的要求。由本研究成果建置之三維立體地圖，就細緻度和便利性而言，效果遠較傳統二維地籍圖為佳，因此本研究可大膽推論；由建置之三維立體地籍圖，將會是未來趨勢。

This research is based on the following research purposes to conduct experiments: 1. Test new equipment combined with the use of e-GNSS technology. 2. Using Multi-Satellite Measurement and 3D LiDAR technology and ＂Supplementary Control Point Off the Ground＂. 3. Establish a three-dimensional cadastral map. According to the data analysis of this experiment, the 3 ground control points and 15 control points are arranged, and the difference of the plane position is between 0.006~0.052m, which is in full compliance with the cadastral survey implementation regulations. The maximum error of the numerical method in the remeasurement area is 2~6cm. Requirements within. The 3D map produced by this research is far better than traditional 2D cadastral maps in terms of detail and convenience. Therefore, this research boldly concludes that the construction of 3D cadastral maps will be the future trend.
