摘要
为快速、准确地获取高速公路建设项目任意时点的实施状况,基于无人机系统,设计高速公路边坡数据采集流程,分析无人机航摄数据处理过程,提出模糊数据提取并恢复的方案,制定高速公路边坡数据精度核验的依据。以贺巴高速AK0+450—AK0+590左侧路堑边坡为依托,进行实证分析,验证该模式的适用性。结果表明,无人机坐标测值与GPS RTK实测坐标值坡高的平均偏差率为0.6%,坡率的平均偏差率为0.27%,平台宽的平均偏差率为0.8%,满足高速公路边坡的应用需求。基于无人机系统对高速公路边坡进行数据采集,能够实现及时准确地获取建设项目信息,与人工现场巡检相比,大大地提升了安全性、工作效率和经济性,对实现高速公路建设项目的智能化管理具有一定的实践价值。
In order to quickly and accurately obtain the implementation status of the highway construction project at any point in time,based on the UAV system,the highway slope data collection process was designed,the UAV aerial photography data processing process was analyzed,and the fuzzy data extraction and recovery plan was proposed,the basis for the accuracy verification of highway slope data was developed.Relying on the slope on the left side of Heba expressway AK0+450-AK0+590,an empirical analysis was conducted to verify the applicability of the model.The results showed that the average slope height deviation rate between the UAV coordinate value and the GPS RTK measured coordinate value was 0.6%,the slope rate average deviation rate was 0.27%,and the platform width average deviation rate was 0.8%,which met the requirements for highway slopes application.Data collection on highway slopes based on the UAV system can achieve timely and accurate acquisition of construction project information.Compared with manual on-site inspections,it greatly improves safety,work efficiency and economy.It has certain practical value for realizing the intelligent management of expressway construction projects.
