The present disclosure provides methods and apparatus for determining changes in location and/or orientation of a mobile device. The method comprises: obtaining a first data stream representing a first estimated change in position and/or orientation of the mobile device in each of a plurality of time frames; obtaining a second data stream representing a second estimated change in position and/or orientation of the mobile device in each of the plurality of time frames, where the first data stream has a higher accuracy than the second data stream and the first data stream has a lower robustness than the second data stream; and determining a change in position and/or orientation of the mobile device using the first estimated change or the second estimated change in response to a comparison of a change in the first representation and a change in the second representation in each of the plurality of time frames. 本公开提供用于确定移动设备的位置和/或定向的变化的方法、装置。方法包括：获取第一数据流，第一数据流表示移动设备在多个时间帧中的各个时间帧中的位置和/或定向的第一估计变化；获取第二数据流，第二数据流表示所述移
