1、引言随着国家经济建设的突飞猛进,资源调查和环境监测工作越来越重要,任务周期越来越短,常规卫星和航空遥感手段己难以满足应用所需,特别是许多分辨率要求高、时间要求快的应急动态监测缺乏有效的手段。现有小型无人机系统为空间信息监测提供了一种数据快速获取、处理、应用分析一体化的新型技术手段,一些小型无人机系 1. Introduction As the country’s economy progresses by leaps and bounds, resource surveys and environmental monitoring work are becoming more and more important. As the mission cycle becomes shorter and shorter, the conventional satellite and airborne remote sensing methods have been unable to meet the needs of applications. In particular, many require high resolution, Time-critical emergency dynamic monitoring of the lack of effective means. The existing small UAV system provides a new type of technical means for data acquisition, processing and application integration for spatial information monitoring. Some small UAV systems
