Provided are a bus route prediction method and system based on facial recognition. The method comprises: by means of facial recognition, acquiring passengers, who get on a bus and get off the bus, from an acquired video stream, and determining stations at which the passengers get on the bus and stations at which the passengers get off the bus; by means of facial recognition, determining whether the passengers who get on one bus are passengers who got off another bus, and if so, determining transfer stations of the passengers; associating the stations at which the passengers get on the bus, the stations at which the passengers get off the bus, and the transfer stations of the passengers to acquire bus routes of the passengers; and predicting the requirements for bus routes on the basis of the acquired bus routes of all passengers. The method, which performs, on the basis of facial recognition technology, face capture and recognition matching on passengers who get on a bus and get off the bus to predict complete bus routes for public travel, and scientifically and rationally plans urban bus routes by using information of the complete bus routes, so that the operation efficiency of urban buses is higher.
