摘要
随着科技的进步,越来越多的无人机被广泛应用于测绘、林业、矿业、交通、水利等行业,成为数据采集的重要工具。但其最初的采购成本较高,令很多人望而却步。如何在不影响精度的情况下降低无人机采购成本,使其更适合平民化航测已成为目前无人机领域亟待解决的问题之一。所以本文以大疆Mavic 2 Pro为例,从数据采集、数据预处理、影像信息提取、数据检查和制图表达等多个环节对1∶500地形图的制作进行了探讨,为以后的大比例地形图的制作提供了参考方案。
With the advancement of technology,more and more UAV are widely used in surveying,forestry,mining,transportation,water conservancy and other industries,becoming an important tool for data collection.However,its initial procurement cost is high,which has discouraged many people.How to reduce the procurement cost of drones without affecting the accuracy,making it more suit-able for civilian aerial surveys has become an urgent problem to be solved in the field of UAV.Therefore,this paper takes Dajiang Ma-vic 2 Pro as an example to discuss the production of 1∶500 topographic maps from data acquisition,data preprocessing,image infor-mation extraction,data inspection and graphic representation.It provides a reference solution for production of large-scale topographic map.
