The invention provides a horizontal dimension airspace conflict detection method. The method comprises the steps of constructing direction bounding boxes, performing intersection detection on the direction bounding boxes, and performing convex polygon intersection detection and horizontal safety interval detection on the intersected direction bounding boxes. According to the method, the direction bounding boxes are constructed, intersection detection of the direction bounding boxes is carried out firstly, airspace pairs needing refined conflict detection are screened out more accurately, the screening effect is good, the operand of subsequent polygon intersection detection can be reduced, and the overall operation efficiency is improved. When polygon intersection detection is carried out, the shortest distance of the projection polygon of the airspace on the horizontal plane is calculated, and has advantages that, compared with the horizontal safety interval between the airspaces, missed detection is prevented, and the accuracy of airspace conflict detection on the horizontal dimension is improved.

    本发明提供一种水平维度空域冲突检测方法,包括:构建方向包围盒、方向包围盒相交检测、对相交的方向包围盒进行凸多边形相交检测、水平安全间隔检测;本发明通过构造方向包围盒,先进行方向包围盒相交检测,更精确地筛选出需要进行精细化冲突检测的空域对,筛选效果好,能够减少后续进行多边形相交检测的运算量,提升整体运算效率;本发明进行多边形相交检测时,计算出空域在水平面上的投影多边形的最短距离,与空域之间的水平安全间隔比较,防止“漏检测”,提高了水平维度上空域冲突检测的精确度。
