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, Chinas 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.
