摘要
在无人机应急测绘保障中,存在航线设计不规则、航摄倾角过大等问题,如果利用传统航摄软件处理这类影像将会消耗较长的时间,进而严重影响应急测绘保障服务的时效性。为此,提出了一种利用Photo Scan Pro软件快速生成正射影像和点云的方法来解决此类问题。通过在多次地质灾害预防及处置中的实际应用,表明该方法能够为测绘应急保障服务提供及时有效的影像数据。
Due to irregular flight route, low image quality and unstable flight attitude, it is really difficult to perform UAV imagery data processing using traditional photogrammetric software. For emergency response, a stable,highly automatic and time-efficient software solution is always highly demanded. In this paper, the authors present a UAV imagery solution for emergence using Agisoft PhotoScan Pro software to offer orthomosaic and dense point cloud service. It is held that this method can provide timely and effective scientific image for emergence, as shown by several emergency response practical applications.
