Position abnormity determination method and recommendation point determination method

The embodiment of the invention discloses a position anomaly determination method and a recommended point determination method, and the method comprises the steps: determining a first parameter index, including a fixed point parameter and/or a tail end yaw parameter, of at least one point of interest according to historical travel data in a first preset time period; determining a second parameter index corresponding to each interest point according to the difference between a first parameter index corresponding to each interest point in a second preset time period and a historical first parameter index, and determining an abnormal parameter of each interest point according to the first parameter index and/or the second parameter index of each interest point, and in response to the fact that the abnormal parameter meets a preset condition, determining that recommendation point abnormity exists in the corresponding interest point. Therefore, according to the embodiment, the abnormal recommendation points in the
