摘要:

无人机低空遥感技术以其机动灵活、高效精准及受气候、空域条件约束较小等特性,在测绘地理信息应急保障服务等领域得到广泛应用。由于西部山区受地形复杂、高原高寒等复杂恶劣环境限制,单机单载荷获取技术无法及时高效稳定地为应急救援提供支撑,亟需对无人机低空遥感技术进行升级。本文从四川省应急测绘实践出发,在无人机的高原稳定作业、单平台多载荷、灾情动态分析等方面开展了大量研究工作,相关成果在九寨沟地震等应急测绘保障工作中发挥重要作用。

Abstract:

The low-altitude remote sensing technology of UAV has been widely used in the fields of emergency surveying and mapping due to its characteristics of flexible maneuverability, high efficiency, accuracy, and little constraint of climatic and airspace conditions. However, due to the complicated and harsh environment, high altitude and cold in the western mountainous area, single machine and single sensor acquisition technology failure to provide timely and efficient protection for emergency rescue, so it is urgent to upgrade the low-altitude remote sensing technology of UAV. Based on the surveying and mapping emergency practice of Sichuan province's, this paper has carried out a lot of research work on the plateau stability operation, single platform multi-sensor, high-speed transmission and other aspects. The achievements played an important role in the emergency surveying and mapping support work of Jiuzhaigou earthquake.

Key words: single machine multiple sensor, cluster collaboration, disaster geographical information, disaster spatial analysis
