After training on three five mile data sets, I was able to get very accurate speed/distance estimates for subsequent runs (say 99%+). The method? 1st derivative of accelerometer data to determine cadence. Then correlate cadence with actual speed with a simple linear regression when GPS data was available. This was more intended for dead reckoning on a wrist mounted device, though. We had a 3 axis accelerometer and a 3 axis magnetometer. |
