四川茂县山体垮塌_激光三维扫描无人机勘察茂县山体垮塌现场Sichuan Maoxian mountain collapse_ laser 3D scanning UAV reconnaissance of Maoxian landslide site-贴身护美

 

6月24日凌晨5时38分,特大高位山体垮塌在茂县叠溪镇新磨村悄然而至,1000万立方的山石倾泻而下,不到两分钟,这个平日里热闹美丽的小村庄被完全掩埋在数十米之下,垮塌造成河道堵塞2公里,40余户100余人被掩埋,截至25日14时,挖出遇难者遗体10具,仍有93人失联。

26日清晨,一架拥有8个螺旋桨的巨型无人机在茂县山体垮塌现场缓缓升起,无需遥控操作,只要预先设定飞行坐标,该无人机就可按照坐标路线自动导航飞行。这款三维激光扫描无人机于25日夜紧急调运至茂县,扫描完成整个垮塌现场只用了30分钟。

 

通过三维激光扫描,可以对垮塌现场的地形进行快速测绘建模,得到整个受灾现场及周边的数字模型,形成三维地形图,并依据该3D模型测算救援工作需挖掘出来的土方量,指挥中心可依靠该精细化模型决定下一步救援计划,以便更加科学有效地实施救援。

救援队专家刘继廷的电脑上看到,在一张三维模拟图中,显示了被还原的垮塌现场及周边环境的全景,“我们在电脑屏幕上可以看到垮塌现场的任何细微变化,这种变化达到厘米级,可帮助预判沉陷、二次垮塌等现象发生。”刘继廷说,“由于现场树木茂密,传统的遥感影像技术无法获取树林下的实际地形,而激光雷达则可以自动去除树木所占空间,得出村庄本来的面目,以获取精确的地形数据。”

通过无人机扫描后得出的三维图像,使得救援组织更加科学有效。3D扫描技术的广泛应用也将在更多领域造福人类。

  On June 24th at 5:38 in the morning, super high mountain collapsed in the Maoxian town of Diexi new mill village quietly, 10 million cubic meters of rocks pouring down, less than two minutes, the usual lively beautiful small village was completely buried in the tens of meters below the collapse caused by blocked river 2 kilometers, more than 40 households of more than 100 people were buried. As of 25 May 14, dug up the remains of 10 victims, 93 people are still lost. The morning of the 26 day, a giant with 8 propeller UAV in Maoxian landslide site rises slowly, without the need for remote operation, as long as the pre-set flight coordinates, the UAV can be in accordance with the coordinate automatic navigation flight route. The three dimensional laser scanning unmanned aerial vehicle (UAV) was transported to Maoxian 25 days and nights, and it was only 30 minutes after the whole scene was collapsed. Through 3D laser scanning, can be quickly collapsed on the mapping and modeling terrain, digital model of the disaster scene and the surrounding, forming a three-dimensional topographic map, and on the basis of earthwork estimates of the 3D model to dig out the rescue work, the command center can rely on the refined model determines the next bailout, so that more scientific the effective implementation of the rescue. See the rescue team expert Liu Jiting on the computer, in a three-dimensional simulation map, shows the reduction of the collapse of the scene and the surrounding environment of the panorama, "we can see the scene of the collapse of any small change on the computer screen, this change can reach centimeter level, help to predict subsidence, collapse phenomenon two." Liu Jiting said, "because the trees, the traditional remote sensing technology can not get the actual terrain under the trees, and the laser radar can automatically remove trees occupied space, the village was really like, in order to obtain accurate topographic data." The 3D images obtained by unmanned aerial vehicle scanning have made rescue organizations more scientific and effective. The widespread use of 3D scanning will also benefit mankind in more fields.相关的主题文章:
