Abstract
It is digit monitoring system with double confirm of car code and car characteristics, which comprises the image catching module, car code identification module, car characteristics catching module and comparing module. Besides the normal monitoring functions, it gets the car codes and characteristics through image catching module and compares them by identification module and records the comparing results to make the double confirmation.
Description
Technical field
The present invention relates to a kind of digital monitor system, the digital monitor system that particularly a kind of testing vehicle register is confirmed.
Background technology
A complete safety system, except the identity that will confirm this object, should consider to add the contrast of characteristics of objects, as long as otherwise the identity (for example car plate and I.D.) of stealing or forging this object, under the contrast that does not have characteristics of objects, this safety system is still leaky existence; Yet, digital monitor system commonly used, the usefulness of most only conduct monitoring, especially for vehicle monitoring, be at most that automobile image is carried out the automatic identification of car plate, can't further utilize the resulting image of monitoring to do higher level contrast, for example confirm whether the number-plate number is consistent with the car type of vehicle, for the management place that utilizes digital monitor system, be easy to generate the leak or the careless mistake of saving from damage; This shows that above-mentioned monitoring technique commonly used fails its function is fully brought into play, and need improve this.
Summary of the invention
The object of the present invention is to provide the digital monitor system of a use number-plate number and vehicle characteristics double acknowledge, the digital monitor system that improvement is commonly used originally provides safer identification mechanism, to guarantee the turnover safety of vehicle.
The technical solution adopted in the present invention is that the digital monitor system of the use number-plate number and vehicle characteristics double acknowledge mainly is made of image extraction module, number plate recognition module, vehicle characteristics acquisition module and vehicle characteristics contrast module.Image extraction module includes camera lens, video camera, network video forwarder (Video server) or contains the computing machine of Frame Grabber; Camera lens and camera mounting are located at the place that desire is monitored, cooperate the network video forwarder image to be sent to the computing machine of remote monitoring, except using the network video forwarder, the Frame Grabber of also computing machine can being arranged in pairs or groups is erected near the guarded region, can be in real time in front-end processing or utilize the TCP/IP network transmission function, send image to the remote monitoring computing machine and process.
At long-range supervisory control comuter or near-end contains on the computing machine of Frame Grabber, see through image extraction module, the number-plate number of desiring monitoring vehicle by acquisition of number plate recognition module and identification is as testing vehicle register, again by vehicle characteristics acquisition module acquisition vehicle characteristics; The vehicle characteristics acquisition module can use the mode of image processing to come the automatic pick-up feature, also can obtain feature by the mode of miscellaneous equipment or artificial input, as infrared ray or laser scanner etc.; The general vehicle feature is to be decided by the user, on the automobile image dust head this vehicle is arranged is compact car or large car, car type model, the moulding of vehicle front air intake opening or whole automobile image; And that number-plate number acquisition mode also has is a variety of, the number-plate number in the automatic identification automobile image that can use a computer or with artificial inputting license plate number.
Vehicle characteristics contrast module then is to do contrast at being present in the vehicle characteristics in the Computer Database and the vehicle characteristics of online acquisition, the data that the vehicle characteristics and the identity of acquisition are transferred in computing machine and the database contrast automatically, in the similar scope of allowing, the vehicle that can allow identity and feature meet passes through, for dissimilar vehicle characteristics, send suitable warning message, can improve security and convenience.
The digital monitor system of the use number-plate number provided by the present invention and vehicle characteristics double acknowledge when comparing with aforementioned current techique, has following advantage:
1. can carry out authentication and the dual comparison of vehicle characteristics, to promote security of system.
2. monitor staff's picture format management interface is provided, can alleviates monitor staff's work load.
Therefore, the invention provides safer identification mechanism, guaranteed the turnover safety of vehicle.

Embodiment
Fig. 1 and Fig. 2 are the specific embodiments of the digital monitor system of the use number-plate number of the present invention and vehicle characteristics double acknowledge, with the pay parking is example, native system is mainly by vehicle inductive coil 11,12, camera lens and video camera 13,14 and supervisory control comuter 15, and cooperate image extraction module 31, number plate recognition module 32, vehicle characteristics acquisition module 33 and vehicle characteristics contrast module 34 to constitute.
The car plate image 311 that number plate recognition module 32 is captured at image extraction module 31, carry out automatic identification 322 of car plate or manual type identification input 321, after picking out the number-plate number 323, the vehicle characteristics of preparing to be captured with vehicle characteristics acquisition module 33 333 stores or compares.
33 of vehicle characteristics acquisition modules can automatically capture this vehicle characteristics 331, also can be by artificial input vehicle characteristics 332, spendable feature such as car body color, car light shape or car body profile, if the vehicle 21 of inlet is just noted down feature in database 344, the feature contrast similarity 343 when if 22 on the vehicle of outlet can utilize vehicle characteristics contrast module 34 to enter the parking lot with this vehicle again, if similarity is enough high, (following this vehicle still might enter this parking lot once more then the feature in the database can be upgraded 347, therefore can carry out the database update action), or with its deletion; If similarity is too low, the message 346 that then can give a warning, obtained image 311 and present image when seeing through this vehicle and entering the parking lot allows management or security personnel notice whether the number-plate number of this vehicle conforms to the vehicle appearance feature.
Whether the decision of vehicle characteristics must consideration can be used to contrast, and will consider its degree of stability, if can't find control methods to calculate similarity or the feature difference of getting is too big at every turn, then this feature just is not suitable for using; With this routine parking lot supervisory system, the image-type feature can be used to comparison, and the more efficient practice is with acquisition car body color, car light profile and features such as air intake opening position and shape; Also whole image can be considered as the feature of this vehicle, then can locate earlier during contrast, and then the qualification contrast district compares according to the car plate position.
Except the application of this routine parking lot monitoring, the management and the stolen car that also can be applicable to people and thing are investigated and seized, as long as this object has unique authentication, and have the feature of notable difference; This two the dual contrast of identity and feature has been arranged, can make the security of supervisory system be promoted to higher level.
