The invention discloses a multi-source data fusion aircraft takeoff failure obstacle screening method and system, and the method comprises the steps: constructing a rasterized airport peripheral digital terrain model, fusing the airport peripheral multi-source obstacle data and takeoff runway data through the model, dividing a failure protection region through simulated flight, and carrying out the segmentation in the model, performing rasterized pixel statistics by using a focus statistical algorithm, screening all focuses, storing the focuses as a first screening obstacle database, and correspondingly projecting each obstacle of the first screening obstacle database to a nominal track; and constructing a rectangular coordinate system taking the tail end of the takeoff runway as an original point to further screen and judge the obstacles, and screening to obtain key obstacle data and outputting the key obstacle data. The automatic obstacle screening method can realize automatic obstacle screening, is used for screening, analyzing and calculating failure performance obstacles during takeoff of transportation aircrafts, has the advantages of good screening effect, high screening quality, high practicability and the like, and improves the working efficiency.

    本发明公开了一种多源数据融合航空器起飞一发失效障碍物筛选方法及系统,构建有栅格化的机场周边数字地形模型,模型融合了机场周边多源障碍物数据及起飞跑道数据,通过模拟飞行划设一发失效保护区并在模型中进行分割,然后利用焦点统计算法进行栅格化像元统计并筛选所有焦点存储为第一筛选障碍物数据库,将第一筛选障碍物数据库的各个障碍物对应投射到标称航迹上,构建以起飞跑道末端为原点的直角坐标系进行各个障碍物进一步筛选判断处理,筛选得到关键障碍物数据并输出。本发明能够实现自动化筛选障碍物,用于运输类飞机起飞一发失效性能障碍物筛选分析计算,具有筛选效果佳、筛选质量高、实用性强等优点,提高工作效率。
