Automatic mapping of aerial survey
航测自动成图

摘要

随着现代科技的发展,无人驾驶的飞行测试方法获得了不断的发展和提高,也开始在许多行业取得了良好的运用。近些年中国的测绘科技也取得了迅速进展,无人机航测科技也起了重要的作用,能够克服传统测绘技术费时费力、精度低的缺点。但无人驾驶飞机飞行的技术也会被某些外部条件所影响,从而导致成的准确性下降,必须在实际使用中严格控制这些要素,提升其如下图的准确性。本文根据无人驾驶飞行器空中探测技术的发展、飞行控制等方面论述了影响其成图精度的主要因素,并提出相应的对策。

Abstract

With the development of modern science and technology, unmanned flight test methods have been continuously developed and improved, and have also begun to make good use in many industries. In recent years, China's surveying and mapping technology has also made rapid progress, and UAV aerial survey technology has also played an important role in overcoming the shortcomings of traditional surveying and mapping technology, such as time-consuming, laborious and low accuracy. However, the technology of pilotless aircraft flight will also be affected by some external conditions, which will lead to a decline in accuracy. These factors must be strictly controlled in actual use to improve the accuracy as shown in the figure below. In this paper, according to the development of aerial detection technology and flight control of unmanned aerial vehicles, the main factors affecting the mapping accuracy are discussed, and the corresponding countermeasures are proposed.
