Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0017] see Figure 1-3 As shown, a vehicle overspeed detection system includes:
[0018] The sign that can delay displaying information is installed on the side of the road, and is made of long afterglow materials with different luminous durations into a predetermined shape. Under the illumination of the car lights walking on the road, the sign can appear in the form of light a first predetermined pattern and a second predetermined image;
[0019] The camera is installed at a predetermined position on the road and is at a predetermined distance from the sign. When the vehicle continues to drive in the same direction, passes the position where the sign is located, and enters the imag...

The invention discloses a vehicle overspeed detection system, comprising: a sign capable of displaying information in a time delay manner, wherein the sign is installed on one side of a road and is formed into a predetermined shape by a long afterglow material having different illuminating time lengths, and the sign can present a first predetermined pattern and a second predetermined image in a form of illumination under the illumination of an automobile lamp travelling on the road; a camera installed at a predetermined position on the road, spaced apart from the sign for a predetermined distance, and used for starting a flash lamp to perform shooting so as to collect the pattern of the sign at the moment and a licence plate of a vehicle when the vehicle continues to travel along the samedirection and passes by the position where the sign is located to enter an image collection area of the camera; and a processor connected with the camera and used for processing the pattern of the sign and the picture of the licence plate of the vehicle collected by the camera, and judging whether the vehicle is overspeed according to the shape of the pattern. The vehicle overspeed detection system disclosed by the invention can quickly judge whether the vehicle is overspeed while recording the license plate of the vehicle on the road without road lamp or on the road with dark light.
Description
technical field [0001] The invention relates to the technical field of vehicle speed measurement, in particular to a vehicle overspeed detection system. Background technique [0002] On some roads without street lights, although there are surveillance cameras that can record passing vehicles (record license plate numbers by taking pictures with flash lights). However, due to the road without street lights, the camera cannot determine the position of the vehicle as easily as during the day, so it cannot reliably determine whether the vehicle is speeding by calculating the quotient of the distance and time recorded by the camera. Contents of the invention [0003] The object of the present invention is to aim at the technical defects existing in the prior art, and provide a vehicle overspeed detection system which is especially suitable for measuring the speed of vehicles on roads without street lights or on dark roads. [0004] The technical scheme adopted for realizing th...
