The invention discloses a method for judging conflict between an aircraft and a vehicle in an airport based on multi-key-point detection, and the method comprises the steps: obtaining images of the aircraft and a guarantee vehicle in an airport apron through an airport monitoring camera; respectively identifying the aircraft and the support vehicle in the airport by using a target detection algorithm, and acquiring position information of the aircraft and the support vehicle in the airport apron by using a coordinate conversion algorithm; dividing a nose, an engine, a wing tip and a horizontal tail tip of the aircraft and a safety area of a guaranteed vehicle based on the aircraft in-place deceleration model and the guaranteed vehicle motion model; and safe area conflict determination and alarm: according to the safe area of the detected aircraft, determining whether the guaranteed vehicle invades the safe area of the detected aircraft, and if yes, giving an early warning. Through the technical scheme provided by the invention, the target pixel coordinates can be converted into the actual coordinates of the airport apron scene in real time, the conflict judgment and detection precision is improved, and refined identification and conflict pre-warning of each key part of the aircraft are realized.

    本发明公开了基于多关键点检测的机位内航空器与车辆冲突判定方法,包括:通过机位监视摄像头,获取机坪内航空器和保障车辆的图像;利用目标检测算法分别识别出机位内的航空器与保障车辆,并通过坐标转换算法获取航空器和保障车辆在机坪内的位置信息;基于航空器入位减速模型及保障车辆运动模型对航空器的机头、发动机、机翼翼尖、平尾翼尖以及保障车辆的安全区进行划设;安全区冲突判定及告警,依据被检测航空器的安全区,判断保障车辆是否侵入被检测航空器的安全区,若侵入则发出预警。通过本发明所提供的技术方案,可以实现将目标像素坐标实时转化为机坪场面实际坐标,提升了冲突判定检测精度,并实现航空器各关键部件的精细化识别和冲突预告警。
