Problems solved by technology

[0002] Existing vehicle speed measurement mainly relies on professional speed measurement equipment, such as radar speed measurement, laser speed measurement, ultrasonic speed measurement, etc. When a vehicle is found to be speeding, cooperate with the license plate capture and license plate recognition system for license plate recognition. Although the existing professional speed measurement equipment has high accuracy, However, the combination of test equipment and vehicle capture equipment is required to complete the license plate recognition, which is costly and cannot restore the actual condition of the vehicle during the speeding period.

Embodiment Construction

[0013] like figure 1 Shown is the operating environment diagram of the preferred embodiment of the vehicle traveling speed measurement system of the present invention. The operating environment includes a sensing device 1 and an imaging device 2 appearing in pairs, a server 3 , an installation mechanism 4 and a communication component 5 , and the vehicle speed measurement system 6 runs on the server 3 side. The imaging device 2 communicates with the server 3 through the communication section 5 .

[0014] The sensing device 1 is used to sense whether the vehicle 7 has driven to the monitoring and capturing position and start the camera device 2 to capture the picture information of the vehicle 7. The sensing device 1 can be installed on the side of the road, on the road or on a pole in the middle of the road, and the sensing method can be through shooting , reflection or pressure sensing, etc., as long as it can sense the vehicle and send a signal to start the camera device 2 ...

Abstract

In a method for measuring a speed of a vehicle, the method starts a first motion sensor to sense a first position of the vehicle controls a first camera to capture a first image of the vehicle, and records a first time. A license plate number of the vehicle is identified from the first image, and a length of the vehicle is obtained from a database according to the license plate number. The method starts a second motion sensor to sense a second position of the vehicle controls a second camera to capture a second image of the vehicle, and records a second time. The method calculates a moving distance of the vehicle according to the first and the second position and the length of the vehicle, and calculates a speed of the vehicle according to the moving distance, the first time and the second time.
