The invention discloses a method for detecting vehicle speed based on road monitoring videos. The method comprises the following steps: (1) dividing a lane using a lane marking line identification method and eliminating unnecessary background; (2) obtaining lane width information according to lane images; (3) calculating the actual distance represented by each pixel point; (4) solving the correction factor Beta which is used for correcting the actual lane distance represented by each pixel point; (5) calculating the optical flow of the vehicle to obtain the trajectory of the vehicle; (6) calculating the actual moving distance of the vehicle; (7) multiplying the correcting the distance by the correction factor to correct the distance; (8) calculating the speed. According to the invention, a video image analysis technology is adopted to decrease the cost of vehicle speed monitoring and speeding behavior recording; and in addition, the method also has the function of expanding the vehicle speed monitoring scope, and vehicle speed monitoring can be implemented at any place with cameras.
