| description | The invention discloses a driving track optimization method which comprises the following steps of acquiring satellite positioning data and performing abnormal point detection preprocessing; performing clustering detection according to the satellite positioning data after preprocessing; performing smoothing processing on the satellite positioning data; and extracting a key driving characteristic.According to the driving track optimization method, filtering preprocessing is performed on the acquired satellite positioning data, thereby reducing influence of error satellite positioning data points to driving behavior detection. According to the driving track optimization method, clustering detection is performed on the satellite positioning data after preprocessing, thereby eliminating influence of satellite positioning drifting in a stationary state, reducing data volume, and reducing data traffic and server storage cost. According to the driving track optimization method, Kalman filtering processing is perform |
