在机坪上，航空器与保障车辆主要有滑行和停放两种状态。不同状态下，两者对地面空间的占用情况是不同的。考虑其外形轮廓、机坪运行要求的安全净距、制动距离等因素，从计算机图形学角度，对机坪上的航空器或车辆划设冲突警戒区，通过检测区域重叠的方法，判断是否存在冲突，进而实现对机坪的安全监视。仿真结果表明，当两架飞机的冲突警戒区重叠时，外形轮廓区域显示黑色并告警。
在機坪上，航空器與保障車輛主要有滑行和停放兩種狀態。不同狀態下，兩者對地麵空間的佔用情況是不同的。攷慮其外形輪廓、機坪運行要求的安全淨距、製動距離等因素，從計算機圖形學角度，對機坪上的航空器或車輛劃設遲突警戒區，通過檢測區域重疊的方法，判斷是否存在遲突，進而實現對機坪的安全鑑視。倣真結果錶明，噹兩架飛機的遲突警戒區重疊時，外形輪廓區域顯示黑色併告警。

In apron, aircraft and service vehicles mainly have two states:taxiing and parking. Under different conditions, both of them occupy differ-ent space on the ground. According to characteristics, safety clearance of the aircraft and the braking distance, from the point of view of computer graphics, design a conflict alert zone for the aircraft and service vehicles in apron. By the method of testing whether conflict alert zone have a common part,detemines a conflict exists or not was determined. And, realizes the safety monitoring of apron. With the help of simulation, draws a conclusion was drawn that when conflict alert zone of two aircrafts have a common part, the contour area show black and alerting at the same time.
