中文摘要 本研究探討車載與空載光達對於公路邊坡的辨識能力,由於兩種光達的點雲資料都有各自的死角,透過檢視光達點雲的融合來分析車載與空載光達對於公路邊坡的點雲涵蓋率及解析能力。

空載光達為往下掃描死角多為垂直向遮蔽如樹木,與坡度陡峭的地區也會因為落差大造成遮蔽死角而缺少資料點。車載光達使用兩個與測量車行進方向夾45°的掃描頭進行掃描,死角多發生在公路轉彎處、邊坡坡面不平整或者是邊坡坡度改變處,對下邊坡的量測則受限於掃描頭和道路外緣的夾角與下邊坡的坡度。

空載光達雖可補足車載光達的死角但在點密度上有巨大的差異,而車載光達於測量車可行經處且無死角產生時也能補足空載光達在精度與點雲密度上的不足。

本研究透過車載光達的高密度點雲產製5 cm間距的DEM,並進行球狀點雲密度的計算與紋理分析,將成果二值化並萃取特徵後,可明顯辨別人工邊坡與天然邊坡的不同。並討論空載光達與車載光達在資料處理、產製DEM、公路邊坡上的應用。
英文摘要 This study shows the identification capabilities of mobile and aerial LiDAR for highway slope. Because these two kind of LiDAR all have its own blind spots. By examining the fusion of these LiDAR to check the completeness of point cloud coverage to the highway slope.

Aerial LiDAR is a downward scanning so it’s blind spot mostly result from vertical shadow like trees, or the steep slope. The mobile laser scanners are typically mounted at a 45° angle with respect to the vehicle track. The blind spot of it usually occurred at the corner of highway、uneven slope surface or highangle changing slope.

Although aerial LiDAR data can complete mobile LiDAR data’s coverage but there is a huge difference within point cloud density. And the mobile LiDAR can strength aerial LiDAR data’s accuracy and also the point density within the scannable region.

This study use high point density of mobile LiDAR data to produce 5 cm in-terval DEM, and then performing the circular point density calculation and texture analysis. After the binarized of result then extract the feature, it could clearly identify the difference between nature and artificial slope.
