    • A 3D positioning apparatus is used for an object that includes feature points and a reference point. The object undergoes movement from a first to a second position. The 3D positioning apparatus includes: an image sensor for capturing images of the object; and a processor for calculating, based on the captured images, initial coordinates of each feature point when the object is in the first position, initial coordinates of the reference point, final coordinates of the reference point when the object is in the second position, and final coordinates of each feature point. The processor calculates 3D translational information of the feature points using the initial and final coordinates of the reference point, and 3D rotational information of the feature points using the initial and final coordinates of each feature point. A 3D positioning method is also disclosed.
    • 3D定位装置用于包括特征点和参考点的对象。 物体从第一位置移动到第二位置。 3D定位装置包括:用于拍摄对象的图像的图像传感器; 以及处理器,用于基于所捕获的图像计算当所述对象处于所述第一位置时所述每个特征点的初始坐标,所述参考点的初始坐标,所述对象处于所述第二位置时所述参考点的最终坐标;以及 每个特征点的最终坐标。 处理器使用参考点的初始和最终坐标以及使用每个特征点的初始和最终坐标的特征点的3D旋转信息来计算特征点的3D平移信息。 还公开了3D定位方法。
