摘要: 重庆作为我国西南地区的超大山地城市,城镇区域楼宇密布、人口密集。在新型测绘智能化转型的视角下,为应对复杂空间环境对低空经济的安全发展的挑战,本文聚焦二维、三维低空目视航图编制过程中低空飞行障碍物的提取与分析关键技术,针对地貌复杂、高楼弥补的地理环境,构建了一套基于实景三维的低空目视航图障碍物提取技术框架。相关成果在全市低空目视航图编制项目过程中应用示范,以支撑低空目视飞行导航、安全预警等后续环节,助力低空飞行安全运行。

Abstract: As a mega mountainous city in Southwest China,Chongqing features densely clustered high-rises and concentrated populations in its urban areas.Under the perspective of intelligent transformation in new surveying and mapping,this study addresses safety challenges posed by complex spatial environments to low-altitude economic development.This paper focus on key technologies for obstacle extraction and analysis during the compilation of 2D and 3D low-altitude visual navigation charts.For geographical environments characterized by complex terrain and densely distributed high-rises,a technical framework for obstacle extraction in visual navigation charts is developed based on 3D real-scene modeling.The achievements are applied and demonstrated in Chongqing's citywide visual aeronautical charts compilation project,supporting follow-up processes including visual flight navigation and safety early-warning systems,thereby enhancing low-altitude flight safety operations.

Key words: real-scene 3D, visual aeronautical charts, mountainous city, low-altitude obstruction
