The invention belongs to the technical field of helicopter state recognition, and particularly relates to a multi-sensor fusion air-ground recognition method. A laser altimeter and an ultrasonic altimeter are mounted outside a left/right skin of a front belly of a helicopter body in a helicopter, and a laser altimeter and an ultrasonic altimeter are also mounted outside a left/right skin of a tail cant beam of the helicopter. Forming a left front laser altimeter/left front ultrasonic altimeter, a right front laser altimeter/right front ultrasonic altimeter, a left rear laser altimeter/left rear ultrasonic altimeter and a right rear laser altimeter/right rear ultrasonic altimeter; and according to the measured values of the laser altimeter and the ultrasonic altimeter, and the left front wheel load switch signal, the right front wheel load switch signal, the left rear wheel load switch signal and the right rear wheel load switch signal, the air-ground state identification of the helicopter is realized.
本发明属于直升机状态识别技术领域,尤其涉及一种多传感器融合的空地识别方法。在直升机中机身前部机腹的左侧/右侧蒙皮外部均安装激光高度表、超声波高度表,在直升机尾斜梁左侧/右侧蒙皮外部也均安装激光高度表、超声波高度表,形成左前激光高度表/左前超声波高度表、右前激光高度表/右前超声波高度表、左后激光高度表/左后超声波高度表、右后激光高度表/右后超声波高度表;根据所述激光高度表、超波高度表的测量值,以及左前、右前、左后、右后轮载开关信号实现直升机的空地状态识别。
