摘　　要：由于城市地理信息的复杂性使得测绘信息的视觉感不强,导致测绘精度下降,文章提出了基于无人机低空遥感的城市地理信息测绘技术。利用无人机低空遥感技术进行地表非接触式测绘,完成城市地理信息测绘。实验结果显示,该测绘技术最高精度超过98%,最低精度也保持在96%以上,测绘覆盖面积接近研究区总面积,在研究区地形复杂、建筑物密集的情况下也能保持较高的覆盖率和准确性,可以为城市规划、灾害监测等领域提供可靠的数据支持。Due to the complexity of urban geographic information,the visual perception of surveying information is not strong,resulting in a decrease in surveying accuracy.Therefore,the article proposes an urban geographic information surveying technology based on unmanned aerial vehicle low altitude remote sensing.Utilizing low altitude remote sensing technology of unmanned aerial vehicles for non-contact surface surveying and completing urban geographic information mapping.The experimental results show that the highest accuracy of this surveying technology exceeds 98%,and the lowest accuracy remains above 96%.The surveying coverage area is close to the total area of the research area,and it can maintain high coverage and accuracy even in complex terrain and dense buildings in the research area.It can provide reliable data support for urban planning,disaster monitoring and other fields.
