震后基于无人机快速三维定位被困人员模型研究

针对震后被倒塌建筑物或滑坡埋压的被困人员进行快速定位问题,在阅读大量相关文献的基础上,以无人机遥感、地理信息空间和三维质心定位技术为基础,采用无线信号RSSI测距模型,配合影像范围内基准影像数据辅助定位,构建震后基于无人机快速三维定位被困人员模型。以红河县城区作为研究区,对城区内特定人员进行三维定位,结果表明该模型定位精度高,对震后废墟被困人员营救具有重要意义。

Research on the Model of UAV Fast 3D Positioning of Trapped People after Earthquake

To locate the trapped people who are buried under the collapse of buildings or landslides after the earthquake, on the basis of reading a large number of relevant literatures and based on uav remote sensing, geographic information space and three-dimensional centroid positioning technology, the wireless signal RSSI ranging model is adopted to coordinate with the reference image data in the image range for auxiliary positioning, so as to construct a set of post-earthquake rapid 3D positioning model of trapped persons based on UAV. Taking Honghe County urban area as the research area, the 3D positioning of specific personnel in the urban area is carried out. The results show that the model has high positioning accuracy and is of great significance to rescue the trapped people after the earthquake.
