The invention provides a route distance measuring and calculating method and a route distance measuring and calculating system. The method comprises the following steps of: acquiring an AIS data set; establishing an interactive perception neural network, inputting the AIS data set and a time set into the interactive perception neural network, obtaining an acceleration, based on the acceleration and difference value between a time t and a time t + i, and calculating a first distance value S1 between the time t and the time t + i; extracting instantaneous speed parameters from the AIS data set, establishing a speed set {V0, V1,..., Vi} based on the multiple speed parameters, calculating the average speed from the time t to the time t + i based on the speed set, and calculating a second distance value S2 from the time t to the time t + i based on the average speed and the difference value between the time t and the time t + i; and based on the first distance value S1 and the second distance value S2, calculating a voyage value St from the time t to the time t + i, and forming a route distance by the sum of the plurality of voyage values.
