%X 随着智能芯片朝着微型化趋势发展，无人机也在各个领域崭露头角，无人机测绘技术逐渐成为摄影测量的重要手段。无人机测绘能够较好地保证地理信息数据的现势性和满足高精度需求，且相较于传统方法具有高机动、快速、经济等优势。本文选取大连市付家庄公园为研究区，使用大疆消费级无人机快速地获取该区域的航测影像，并据此制作高分辨率DOM和DSM，在设定80 m飞行高度的情况下，单个像元的分辨率可达2.8 cm。研究表明：该方法可用于紧急情况下的快速出图，所制作的DOM和DSM能为海图要素的快速更新提供坚强有力的数据支撑。<br />
With the development of intelligent chip towards miniaturization, UAV is also emerging in various fields. UAV mapping technology has gradually become an important means of photogrammetry. UAV mapping can better ensure the current situation of geographic information data and meet the needs of high precision, and has the advantages of high mobility. UAV mapping is rapider and more economic compared with traditional methods. This paper selects Fujiazhuang Park in Dalian as re-search area, uses DJI consumer UAV to quickly obtain aerial survey images of the area, and products high-resolution DOM and DSM. When the flight altitude is set at 80 m, the resolution of a single pixel can reach 2.8 cm. The research shows this method can be used for rapid mapping in emergency, and the DOM and DSM can provide strong data support for rapid update of chart elements.<br />
