面向Z-5无人直升机航测的测绘质量检查体系及实证

基于无人直升机开展应急测绘具有重要意义，但目前缺乏针对无人直升机航摄系统的测绘质量检查体系及量化指标。本文提出基于Z-5无人直升机及配套航摄系统的测绘质量检查体系，包含数字航空摄影成果检查、空三加密成果检查和数字正射影像成果检查，并明确重要指标的量化数据。通过实际飞行验证，结果表明，Z-5无人直升机航摄系统能够满足应急测绘精度要求，其中4项内容可以进一步提高量化指标阈值，满足更为精准的无人机测绘要求。

Surveying and mapping quality inspection system and demonstration for Z-5 unmanned helicopter aerial survey

It is of great significance to conduct emergency surveying and mapping based on unmanned helicopter. But at present, there is a lack of surveying and mapping quality inspection system and quantitative indicators for unmanned helicopter aerial photography system. This paper proposes a survey and mapping quality inspection system based on Z-5 unmanned helicopter and supporting aerial photography system, including digital aerial photography results inspection, aerial three encryption results inspection and digital orthophoto results inspection. At the same time, this paper defines the quantitative data of important indicators. Through the actual flight verification, the aerial photography system based on Z-5 unmanned helicopter can meet the requirements of surveying and mapping accuracy.Four of them can further improve the threshold of quantitative indicators, so as to meet the requirements of more accurate UAV mapping.
