摘要
无人机快速高效的特点为传统的航空摄影测量技术提供了有利的补充。本文以消费级旋翼机和专业级固定翼无人机为飞行平台,结合差分GPS技术及专业无人机航测后处理软件,对山区农村村镇和城市高层小区两个不同类型测区的大比例尺地形图航测作业流程进行了介绍和成果分析,验证说明了无人机航测可以达到高精度(平面中误差≤5 cm)测绘,满足大比例尺地形图测绘的可行性。
The technology of unmanned aerial vehicle continues to mature and develop.Combining differential GPS technology and integrated RTK module,low-altitude aerial surveying provides a fast and efficient methods for large-scale terrain mapping.This article mainly discusses the low-cost and high-efficiency completion of large-scale topographic map surveying and mapping,which based on professional aerial survey post-processing software under the orthographic aerial flight mode to meet the needs of high-precision engineering survey projects such as project completion,real estate,and cadastral surveying.
