摘要：
A method to correct for drift in an electronic device is described. The method comprises determining a first center pose of the electronic device; tracking, using a sensor in conjunction with computer vision operating on a processor, at least one key point within a scene when the first center pose is within a tolerance with respect to a reported center pose; determining a derived center poser based upon the first center pose and the at least one key point; disabling the sensor for a predetermined time; determining, after the predetermined time, whether a second center pose is within the tolerance with respect to the derived center pose; tracking, using the sensor, the at least one key point when the second center pose is within the tolerance with respect to the derived center pose; and adjusting the second center pose when there is a difference between the second center pose and the derived center pose.
