Method and device for positioning movable part in X-ray imaging

The embodiment of the invention discloses a method and a device for positioning a movable part in X-ray imaging. The method comprises the following steps: acquiring a three-dimensional image which is shot by using a camera component and represents the movement process of a movable part; motion information, detected by a motion sensor, of the movable part is obtained; and positioning the movable part based on the three-dimensional image and the motion information. According to the embodiment of the invention, the movable part is positioned by combining the three-dimensional image of the movable part and the motion information of the movable part, so that the positioning precision of the movable part can be improved, particularly, the image splicing quality and the positioning precision of a detector can be improved, the overlapping requirement in image splicing can be reduced, and the exposure dose can be reduced. 本发明实施方式公开了一种X射线成像中定位可运动部件的方法和装置。方法包括：获取利用摄像组件拍摄的、表征可运动部件的运动过程的三维图像；获取运动传感器检测的、所述可运动部件的运动信息；基于所述三维
