基于无人机航测技术的平原河道划界技术分析

Technical Analysis of Plain River Delimitation Based on UAV Aerial Survey Technolo

无人机航空测量技术是近年来发展起来的一项新型测量技术,与传统测量手段相比,具有快速、精准、矢量化等优点。依法科学合理划定河道管理与保护范围,是实施河道工程管理与保护的基础性、先导性工作。将无人机航空测量技术应用在河道工程划界工作中,既可以提高划界工作的精准性,又可以提高工作效率,文章以聊城市徒骇河、马颊河划界为例,介绍了无人机航空摄影测量技术在平原区河道划界中的实践应用,指出了无人机航空测量技术在河道划界应用中的主要特点、创新及应用推广,重点介绍了划界的技术路线和关键技术分析,并总结了相关经验,为其他同类河道划界工作提供了经验参考。

UAV aerial measurement technology is a new type of measurement technology developed in recent years.Compared with traditional measurement methods,it has the advantages of fast,accurate,vectorized and so on.The scientific and reasonable delineation of river management and protection scope in accordance with the law is the fundamental and pioneering work for implementing river engineering management and protection.The application of UAV aerial survey technology in river engineering demarcation can not only improve the accuracy of demarcation work,but also improve work efficiency.Taking the demarcation of Tuhai River and Majia River in Liaocheng City as an example,the practical application of UAV aerial photogrammetry technology in river demarcation in plain areas is introduced in this article.The main characteristics,innovation and application promotion of UAV aerial survey technology in river demarcation application are points out.The technical route and key technical analysis of boundary demarcation are emphasized.In addition,relevant experience is summarized.These provide experience reference for other similar river boundarydemarcation work.
