摘  要：公路沿線設(shè)施的尺寸特征是公路資產(chǎn)管理的關(guān)鍵指標，為準確提取公路沿線設(shè)施的尺寸，以三維激光點云與全景相機裝置為核心，集成研發(fā)公路沿線設(shè)施巡檢裝備，開展檢測速度對尺寸特征提取的對比分析實驗。研究結(jié)果表明，檢測速度對尺寸提取的平均測量誤差和最大測量誤差影響較大，呈正相關(guān)的關(guān)系。

Abstract： The size feature of the facilities along the highway is the key index of the highway asset management. In order to accurately extract the size of the facilities along the highway， the inspection equipment of the facilities along the highway is integrated based on the three-dimensional laser point cloud and the panoramic camera device. This paper also caries out the comparative analysis experiment of the detection speed to the dimension feature extraction. The results show that the detection speed has a great influence on the average measurement error and maximum measurement error of dimension extraction， showing a positive correlation.

Keywords： laser point cloud; panoramic image; facilities along highway; dimension feature extraction; highway asset management

公路沿線附屬設(shè)施是公路資產(chǎn)的重要組成部分，主要通過人工拍照巡檢的方式開展數(shù)據(jù)采集與處理，在數(shù)據(jù)處理過程中無法提取沿線設(shè)施的長、寬、高等特征信息，對公路沿線設(shè)施資產(chǎn)的管理造成較大的影響。（剩余3678字）
