A hazard point marking method and a hazard point marking system are provided. The method includes: acquiring, by Augmented Reality (AR) glasses, position information of a hazard point in response to a triggering operation of an inspector, where the position information of the hazard point is used for characterizing a position of the hazard point in a tunnel model; sending, by the AR glasses, the position information of the hazard point to a server; and marking, by the server, the hazard point in the tunnel model based on the position information of the hazard point.
