摘要： Methods and devices for odometry are disclosed. A previous position estimate and a current position estimate for a device are obtained. A current velocity estimate for the device is also obtained. A first distance estimate is calculated based on the position estimates, and a second distance estimate is calculated based on the velocity estimate. These two distance estimates are combined to generate a combined or hybrid distance estimate for the distance travelled by the device.
