Embodiment
Below the invention is described in further details.
A kind of overspeed of vehicle on highway grasp shoot device, comprise Bus-Speed Monitoring unit, central control unit and violation information administrative unit, described Bus-Speed Monitoring unit is for detecting the travel speed of vehicle near monitoring point; Described central control unit is for receiving the information of Bus-Speed Monitoring unit unit transmission and sending instruction after carrying out multilevel iudge; Described violation information administrative unit is for storing the travel speed of over-speed vehicles, hypervelocity time and place, information of vehicles;
Also comprise image acquisition units, described image acquisition units for receive central control unit instruction after take the image of over-speed vehicles and carry out image definition process; Described image acquisition units comprises visibility detection module, the first video capture module, the second video capture module, the 3rd video capture module, image storage module and image denoising module, described visibility detection module is used for starting different video capture modules according to different visibility, first, second and third video capture module described is for taking the image of over-speed vehicles, described image storage module is for storing the image of over-speed vehicles, and the image that described image denoising module is used for for storing carries out denoising process.
As a preferred technical solution of the present invention: the filming frequency of described first video capture module is 35 frames/second, the filming frequency of the second video capture module is 25 frames/second, and the filming frequency of the 3rd video capture module is 15 frames/second.
As a preferred technical solution of the present invention: described image denoising module adopts adaptive wiener filter or morphology scratch filter.
As a preferred technical solution of the present invention: described Bus-Speed Monitoring unit adopts radar meter.
As a preferred technical solution of the present invention: described radar meter selects HD125 velocity radar, built-in two of this HD125 radar meter launches radar and a receiving radar.
As a preferred technical solution of the present invention: described image acquisition units and violation information administrative unit carry out information transmission by cdma network.
Be provided with visibility detection module in image acquisition units of the present invention, visibility detection module can be provided with day mode and Night, takes different mode to take the image of over-speed vehicles by day with night.In the present invention, visibility detection module according to the actual conditions of weather, as fine day, dense fog, heavy rain etc. regulate the filming frequency of video capture module, can improve the force trapping of vehicle image.The present invention, by arranging image denoising module, improves the sharpness of the image of shooting violation vehicle.
Adaptive wiener filter, can adjust the output of wave filter according to the local variance of image, local variance is larger, and the smoothing effect of wave filter is stronger.Its final goal makes the square error of Recovery image and original image minimum.The filter effect of the method is better than mean filter effect, very useful to the edge and other HFSs retaining image, but calculated amount is larger.S filter is to the imaging filtering best results with white noise.
Morphology scratch filter, combines opening and closing for filtering noise, and first to there being noisy image to carry out open operation, optional structure salt matrices is larger than the size of noise, and the result of thus opening is by the noise remove in background.Be finally that closed procedure is carried out to the image that back obtains, the noise on image is removed.Feature according to the method can be known, the image type that the method is suitable for is that the object size in image is all larger, and does not have tiny details, can be relatively good to the effect of such scene image partition.
Radar meter mainly make use of Doppler effect (Doppler Effect) principle: when target is when radar antenna is close, reflected signal frequency will higher than transmitter frequency; Otherwise when target is gone away from antenna, reflected signal frequency will lower than transmitting probability.So by the change numerical value of frequency, the relative velocity of target and radar can be calculated.There is following characteristics: 1, radar beam is large compared with the shadow surface of laser beam (ray), and therefore radar velocity measurement is easy to captured target, need not fine sight.Radar, surveying error during motion is ± 2Km/h, can meet the requirement investigated and prosecuted break in traffic rules and regulations completely.
