为简单起见，我们对舰船甲板模型进行了简化，根据Brretschneider波普的方法，将无人直升机在降落台所在平面上的投影点距离海平面的高度视为无人直升机追踪的甲板高度变化。(For simplicity, we simplified the warship deck model. According to the Brretschneider Pope method, the height of the projection point from the plane of the landing platform to the sea level was regarded as the change of the deck height of the UAV.)
