无人机航测在长江岸线测绘中的应用

无人机航测是一项新兴的测绘技术，以其测图效率高、受地面约束小、自动化成图等优点深受测绘生产单位的青睐。本文利用拓普康天狼星Sirius Pro无人机对泰州的长江岸线进行了航测，生成了高分辨率影像图、数字高程模型、数字地表模型，经检验航测成果的精度满足大比例尺测图的要求，为长江岸线的测绘提供了新的测绘方法，对无人机航测实践具有很好的指导借鉴作用。

Application of UAV aerial survey in coastline surveying and mapping of the Yangtze river

UAV aerial survey is a new emerging technology of surveying and mapping, which is in good graces of the production units of surveying and mapping for its advantages of high surveying efficiency,small ground constraintsand and automatic mapping. This paper describes the application of Topcon Sirius UAV aerial survey in coastline surveying and mapping of the Yangtze river of Taizhou. High resolution images, digital elevation model and digital terrain model have been generated, and the accuracy analysis of the result shows that the aerial survey can meet the requirements of large scale mapping, which provides a new method for coastline surveying and mapping of the Yangtze River.The practice has a good guidance and reference function for UAV aerial survey.
