The invention discloses an aircraft landing gear folding and unfolding state detection device and method.The device comprises a controller and two industrial cameras, the controller is connected with the two industrial cameras, the two industrial cameras are installed on the two sides of the inclined upper portion of a landing gear in an aircraft cabin respectively, and the two industrial cameras cannot be directly irradiated by sunlight at the same time; the field angles of the two industrial cameras can cover the whole undercarriage and can cover all the space when the undercarriage is in a folded/unfolded state. According to the device and the method for detecting the folding and unfolding state of the aircraft landing gear, the aircraft landing gear is shot at different angles through the two cameras by utilizing a double-visual-angle visual detection method, and the folding and unfolding state of the aircraft landing gear is judged from two aspects of two-dimensional image automatic identification and three-dimensional data reconstruction detection, so that the environmental interference is effectively reduced, and the detection accuracy is improved. And in addition, a conventional industrial camera and a controller are adopted, so that the cost is low, and the device is suitable for industrial popularization and application.

    本发明公开了一种飞机起落架收放状态检测装置及方法,该装置包括控制器和两个工业相机,控制器与两个工业相机相连,两个工业相机分别安装在飞机舱内起落架斜上方两侧,两个工业相机不会同时被阳光直射,两个工业相机的视场角能够覆盖整个起落架且能够覆盖起落架处于收/放状态时的所有空间。本发明提供的飞机起落架收放状态检测装置及方法,利用双视角视觉检测的方法,通过两个相机在不同的角度拍摄飞机起落架,并分别从二维图像自动识别和三维数据重建检测两个方面进行飞机起落架收放状态判断,有效降低环境干扰,提高检测的准确性和可靠性,且采用常规的工业相机和控制器即可,成本低廉,适合工业化推广使用。
