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

公路沿线附属设施是公路资产的重要组成部分，主要通过人工拍照巡检的方式开展数据采集与处理，在数据处理过程中无法提取沿线设施的长、宽、高等特征信息，对公路沿线设施资产的管理造成较大的影响。（剩余3678字）
