The invention provides a method, a device and a system for determining the swing angle of a grab bucket of a ship unloader, the two ends of a cart advancing track of the ship unloader are each provided with a camera device, and the view range of each camera device covers the movement range of the grab bucket in the working process of the ship unloader; the determining method comprises the steps that the current position of the ship unloader on the cart advancing track is obtained; videos collected by each camera device are obtained in real time in the working process of the ship unloader; determining a grab bucket swing angle in each frame of image in the video acquired by each camera device; and the current swing angle of the grab bucket is determined according to the two grab bucket swing angles of the corresponding frame images in the videos collected by the two camera devices and the current position of the ship unloader on the cart advancing track. According to the invention, the swing angle of the grab bucket of the ship unloader can be positioned more accurately.
本发明提供了一种卸船机抓斗的摆角确定方法及装置、系统,所述卸船机的大车行进轨道的两端各设置有一个摄像装置,每一个摄像装置的视野范围均覆盖所述卸船机在工作过程中所述抓斗的运动范围;所述确定方法包括:获取所述卸船机在所述大车行进轨道上的当前位置;在所述卸船机工作过程中实时获取每一个摄像装置所采集的视频;确定每一个摄像装置所采集的视频中的每一帧图像中的抓斗摆角;根据两个摄像装置所采集的视频中的对应帧图像的两个抓斗摆角以及所述卸船机在所述大车行进轨道上的当前位置,确定所述抓斗的当前摆角。本发明能够更为准确地对卸船机的抓斗的摆角进行定位。
