The invention provides a continuous red light violation alarm method. The method comprises the steps that when a vehicle passing a lane is sensed at a current intersection, a first picture is shot; whether a red light signal of the lane is in the first picture is detected; if the red light signal is in the first picture, a second picture is shot when the fact that the vehicle disappears is sensed; whether the red light signal of the lane is in the second picture is detected; if the red light signal of the lane is in the second picture, according to the travel time of the vehicle in the lane and a preset vehicle length, the vehicle speed is calculated, and a third picture is shot; whether the red light signal of the lane is in the third picture is detected; if the red light signal of the lane is in the third picture, a license plate number is extracted from the second picture, and the first picture, the second picture and the third picture are integrated into an illegal picture; the illegal picture, the vehicle speed and the license plate number are sent to an alarm server; and when the alarm server determines that the vehicle continuously runs a red light and overspeeds according to the license plate number and the vehicle speed, alarm information is sent to the police near the current intersection. According to the invention, the behavior of continuous red light violation can be timely detected.
