A method for calculating a position and/or orientation of a first object relative to a second object is provided. The method includes receiving an initial absolute position of a first object. The method includes sensing motion of a first object using a first IMU and generating sensed motion data of the first object. The method includes generating, using a controller, a motion signal representative of a motion of a first object. The method includes calculating, using the controller, a current absolute position of the first object using the motion signal and an initial absolute position of the first object. The method includes receiving, from a second object, a current absolute position of the second object calculated using a second IMU associated with the second object. The method includes calculating a relative position and/or orientation of the first object relative to the second object using the current absolute position of the first object and the current absolute position of the second object.

    提供了一种用于计算第一对象相对于第二对象的位置和/或定向的方法。该方法包括接收第一对象初始绝对位置。该方法包括使用第一IMU感测第一对象的运动,并生成第一对象的感测运动数据。该方法包括使用控制器生成表示第一对象的运动的运动信号。该方法包括使用控制器,使用运动信号和第一对象初始绝对位置来计算第一对象当前绝对位置。该方法包括从第二对象接收使用与第二对象相关联的第二IMU计算的第二对象当前绝对位置。该方法包括使用第一对象当前绝对位置和第二对象当前绝对位置来计算第一对象相对于第二对象的相对位置和/或定向。
