摘要
为提高山区高速公路勘测设计中的工作效率,降低野外勘测工作量,提出了一种基于机载激光雷达技术(Li DAR)来实现高速公路勘测设计的数据采集和路线选型。研究结果表明:采用机载激光雷达系统将线路采集的进场数据、点云数据、正射影像反馈回设计人员,设计者可直接利用反馈数据和等高线来进行线路选型和纵断计算,将控制测量与勘查设计同步作业,提高勘测精确度和选线准确度。通过实例验证表明建立的Li DAR系统能够为山区高速公路线路选择提供精确的数据参考,有效降低公路设计勘测工程量。
In order to improve the working efficiency of highway survey design in mountainous areas and reduce the workload of field survey,a kind of data collection and route selection based on airborne laser radar technology(Li DAR)was proposed.The research results indicated that using airborne laser radar system will line the approach of collecting data,point cloud data,orthogonal projection as feedback to the designers,designers can directly use the feedback data and contour to calculation of line selection and longitudinal control survey and prospecting design synchronous operation,improve the survey precision and accuracy of line selection.It is proved by an example that the lidar system established in this paper can provide accurate data reference for highway route selection in mountainous areas and effectively reduce highway design and survey engineering quantity.
