All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "first", "second", and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
The embodiment of the invention provides a method for recording illegal parking behaviors of a plurality of motor vehicles, which is used in an intersection traffic control terminal, wherein the control terminal is connected with video image recording equipment at an intersection and used for controlling the video image recording equipment to track and shoot pictures or record images of the motor vehicles. In some road sections, parking is forbidden or only temporary parking is allowed for a certain time, in front of an intersection, generally in order to prevent illegal parking after a vehicle enters the intersection, a parking forbidding mark or a temporary parking mark is arranged on the road section, illegal parking behaviors cannot be forbidden effectively only under the action of the mark, and meanwhile, the law enforcement difficulty of the illegal parking behaviors is increased. The method for recording the illegal parking behaviors of the plurality of motor vehicles in the embodiment is used for timely and accurately recording the illegal parking behaviors of the motor vehicles, and warns the motor vehicle drivers to comply with corresponding laws and regulations and maintain the traffic order by forcefully monitoring the illegal parking behaviors.
As shown in fig. 1, the method for recording illegal parking behaviors of a plurality of motor vehicles comprises the following steps:
step S1: and starting the video image recording equipment to record the original video information of the section where the parking is forbidden.
And starting a video image recording device arranged on the road section where the vehicle is prohibited to park to carry out video monitoring on the road section, wherein the obtained monitoring video is used as original video information and is used as an original basis for subsequently judging illegal parking of the motor vehicle.
Step S2: the method comprises the steps of shooting a first image with a license plate number for each motor vehicle entering a vehicle identification area, numbering the motor vehicles, dividing original video information into multi-path tracking video information through a video distributor, enabling each motor vehicle entering the vehicle identification area to correspond to one path of tracking video information, and synchronously marking the numbers to the corresponding motor vehicles in the tracking video information.
Firstly, judging whether the motor vehicle enters a vehicle identification area, setting the vehicle identification area on the road surface in a road section where parking is forbidden, and enabling the video image recording equipment to accurately shoot the image of the motor vehicle entering the vehicle identification area by adjusting the height and the angle of the video image recording equipment.
In the process of judging whether the motor vehicle enters the vehicle identification area, the following modes can be adopted:
firstly, whether the image of the motor vehicle enters the image range of the vehicle identification area or not is monitored, and when the image of the motor vehicle enters the image range of the vehicle identification area, the motor vehicle is judged to enter the vehicle identification area. If the image of the motor vehicle does not exist in the vehicle identification area, the fact that no motor vehicle enters the vehicle identification area is indicated.
As another alternative embodiment, the process of determining whether the vehicle enters the vehicle identification area may be as follows: firstly, detecting the position of a motor vehicle by a radar, installing a radar scanner at an intersection, and obtaining the distance between the motor vehicle and the intersection by radar ranging; and when the motor vehicle reaches the position of the preset vehicle identification area of the radar detector, determining that the motor vehicle enters the vehicle identification area. The accurate distance between the motor vehicle and the intersection can be known through radar ranging, the distance corresponds to the distance of the section where the motor vehicle is prohibited to stop, an area before the motor vehicle runs to the section where the motor vehicle is prohibited to stop is set as a vehicle identification area, and after the motor vehicle reaches the preset position, the motor vehicle is judged to enter the vehicle identification area.
When a motor vehicle enters a motor vehicle identification zone, a first image of the motor vehicle with the license plate number is taken, as shown in fig. 2. When the traffic control terminal finds that a motor vehicle enters a vehicle identification area through a picture shot by a video image recording device or laser radar distance measurement, the motor vehicle is photographed, and an image of the motor vehicle with a clear license plate number is shot to serve as a first image. The accuracy of radar ranging is high, and as shown in fig. 3, after the radar identifies an image in the vehicle identification area, the video image recording device is triggered to shoot the image. Because the angle and the height of the video image recording equipment at the intersection are adjusted according to the position of the vehicle identification area, the image of the motor vehicle, especially the number plate of the motor vehicle, can be clearly shot in the vehicle identification area and can also be clearly displayed in the image of the motor vehicle.
In practice, when a number of vehicles are running on the monitored road section, the original video information may simultaneously include running tracks of a plurality of motor vehicles, at this time, the judgment of illegal parking behaviors of the plurality of motor vehicles is directly performed in the original video information, the judgment is easily interfered by adjacent motor vehicles, and the situation that the definition of images of the running tracks of the motor vehicles is not high may exist, so that the difficulty is increased for judging illegal behaviors. Therefore, in the embodiment of the invention, the motor vehicles running into the vehicle identification area are numbered firstly, aiming at each motor vehicle entering the vehicle identification area, the original video information is divided into a plurality of paths of tracking video information by the video distributor, each motor vehicle entering the vehicle identification area corresponds to one path of tracking video information to track each motor vehicle respectively, and the number corresponding to the tracked motor vehicle is marked on the image of the motor vehicle in the tracking video information, so that the number synchronously follows the running track of the motor vehicle, therefore, the corresponding number is displayed in the video image of the tracking video information in the running process of the motor vehicle, which motor vehicle can be clearly known according to the number, and the number is numbered according to the sequence of the motor vehicle entering the vehicle identification area, so that a complex data processing process is not needed, the serial numbers are marked on the motor vehicle for synchronous following, so that a visible unique identifier is formed for each vehicle without spending more time on vehicle identification, and the data processing amount is reduced. The tracking video information can track the running track of the motor vehicle in real time until the motor vehicle exits from a monitoring range, and the monitoring range can be set as required, can be an area where the vehicle is prohibited from parking in a lane and is used for monitoring the illegal parking behavior of the motor vehicle.
Specifically, the method for separating tracking video information of the current tracked motor vehicle from the original video information comprises the following steps: acquiring a current tracked motor vehicle corresponding to the tracking video information, firstly determining which motor vehicle the motor vehicle tracked by the tracking video information needing to be separated is, then extracting a video image corresponding to the driving track of the motor vehicle from the original video information, due to the different driving positions of the vehicles, the positions of the vehicles in the video images may be different, and in order to observe the driving condition of the vehicle to be tracked, meanwhile, the interference of other motor vehicles around the motor vehicle is eliminated as much as possible, the extracted video image needs to be further processed, then amplifying the video image to make the image of the current tracked motor vehicle be positioned in the central region of the video image to obtain tracking video information, after the video image is locally amplified, the motor vehicle has a clearer driving track, is beneficial to observation and is beneficial to subsequent recording of illegal parking behaviors.
Step S3: and judging whether the parking time of the tracked motor vehicle on the section of the forbidden parking road is greater than a preset parking time threshold value or not in the tracking video information.
When the time that the motor vehicle stays on the lane exceeds the preset temporary stay time, the motor vehicle is proved to be illegally parked, the position relation of the motor vehicle in the driving time of the motor vehicle on the lane can be summarized according to the recorded tracking video information to determine, and after the motor vehicle is monitored to be at a certain position and the preset temporary stay time is passed, the motor vehicle is still monitored to be at the same position, and the motor vehicle is proved to have illegal parking behaviors. And judging whether the parking time of the motor vehicle on the section of the road where the parking of the motor vehicle is forbidden is greater than a preset parking time threshold value or not, if so, executing the step S4, otherwise, continuously monitoring the position relation of the motor vehicle in the driving time of the motor vehicle on the lane.
Step S4: and when the parking time is greater than a preset parking time threshold value, a second image of the parking moment and a third image of the parking time exceeding the preset parking time threshold value are intercepted from the tracking video information.
In order to ensure the integrity of the evidence chain, an image of the motor vehicle during illegal parking needs to be intercepted from the tracking video information as a second image, and the time corresponding to the moment is marked. When the parking time of the motor vehicle exceeds the specified temporary parking time of the road section, an image after the temporary parking time is intercepted as a third image, and the third image selects the image with the number and records the time. Therefore, the behavior of illegal parking of the motor vehicle can be clearly recorded through the second image and the third image, and the motor vehicle can be conveniently identified in the tracking video information through the correspondence between the serial number and the motor vehicle.
Step S5: and sending the first image, the second image, the third image and the tracking video information to an illegal database.
The first image is shot in the vehicle identification area, the number plate of the motor vehicle in the area can be clearly displayed, so that the first image can comprehensively display the image information of the vehicle, the second image and the third image reflect the record of illegal parking of the motor vehicle, the illegal information of the motor vehicle can be clearly reflected through the first image, the second image and the third image, and meanwhile, the tracking video information of the motor vehicle in the monitoring area is sent together for the completeness of an evidence chain, so that a complete evidence chain is formed.
The method for recording the illegal parking behaviors of the multiple motor vehicles provided by the embodiment of the invention avoids the problem that the illegal behavior recording is influenced by shielding, unclearness and the like of the motor vehicle number plate far away from the recording equipment for parking, thereby realizing the effective and continuous recording of the illegal parking behaviors of the multiple motor vehicles at any position in the video monitoring range, solving the problem of effectively managing the illegal parking in the whole road section, forming all evidence chains of the illegal parking without manual operation, saving human resources and further improving the processing efficiency of the illegal parking behaviors.
Specifically, in the embodiment of the present invention, when recording illegal parking behaviors of motor vehicles entering a vehicle identification area, a path of tracking video information needs to be separated from original video information for each motor vehicle, so that a large amount of tracking video information is generated, and in practice, only tracking video information corresponding to the motor vehicle in which the illegal parking behaviors occur and a first image with a license plate number are paid attention to and retained, so as to serve as a further implementation manner, as shown in fig. 4, the method for recording illegal parking behaviors of a plurality of motor vehicles further includes:
step S6: and when the parking time is greater than a preset parking time threshold value, recording the parking time and the starting time after parking.
When the parking time is longer than the temporary parking time specified by the road section, the motor vehicle is proved to have illegal parking behaviors, and then the starting time and the ending time of the illegal parking behaviors of the motor vehicle are recorded, so that the subsequent inquiry of the illegal parking behaviors and the judgment of punishment are facilitated.
Step S7: and calculating the time difference between the parking time and the starting time after parking, determining the parking time length according to the time difference, and sending the parking time length to an illegal database.
If the motor vehicle has illegal parking behaviors, the illegal parking time length can be calculated according to the parking time and the starting time after parking, and the traffic management department can process the illegal behaviors according to the corresponding illegal parking time length in the illegal database.
As another further embodiment, as shown in fig. 5, the method for recording illegal parking behaviors of a plurality of motor vehicles further comprises:
step S8: and judging whether the motor vehicle runs out of the section of the forbidden parking road. The parking prohibition section may be a position from the vehicle identification area to the end of the parking prohibition section, so that the illegal parking behavior of the motor vehicle can be accurately identified. When the motor vehicle is driven out of the no-parking section, step S10 is executed, otherwise, the driving track of the motor vehicle is continuously monitored.
Step S9: and judging whether the second image and the third image exist or not after the motor vehicle drives out of the no-parking road section.
If the motor vehicle has illegal parking behaviors, the second image and the third image are generated at the time of parking and at the starting time after parking, so that if the second image and the third image are generated, the illegal parking behaviors exist, and if the second image and the third image do not exist, the illegal parking behaviors do not exist. If the second image and the third image exist, step S10 is performed, otherwise step S11 is performed.
Step S10: when the second image and the third image are present, the tracking video information and the first image are stored.
If the motor vehicle has illegal parking behaviors, the tracking video information corresponding to the motor vehicle, which is separated from the original video information, needs to be stored, so that subsequent query is facilitated.
Step S11: and when the second image or the third image does not exist, deleting the tracking video information and the first image.
If the second image or the third image does not exist, the motor vehicle is indicated to have no illegal parking behavior in the no-parking road section. Images in the monitoring area do not need to be reserved, so that the tracking video information can be deleted, the storage space is saved, and the utilization efficiency of the storage device is improved. In a road section with a large traffic, the traffic volume of vehicles is very large, if data of all vehicles passing through an intersection are reserved, a very large storage space is occupied, and a traffic police manually searches illegal information from the tracking video information, a large amount of time is spent, in the scheme, after a motor vehicle enters a no-parking road section to be monitored, and after the no-parking road section is driven out, whether the motor vehicle has illegal information is obtained through judgment of the illegal information, if the illegal information does not exist, the tracking video information is deleted, if the illegal information exists, the tracking video information is uploaded to a monitoring center to be stored, the schematic diagram of the process is shown in figure 3, in a server of the monitoring center, stored image data can be previewed through an upper computer, and the data can be further processed in a data center or a receiving platform, more traffic data information is provided. Therefore, the monitoring terminals at the intersections do not need to store too much useless information, the utilization rate of resources is improved, the time for manually identifying and tracking the video information by the traffic police is saved, illegal vehicles are automatically found, a complete evidence chain is formed, and more information is provided for traffic management.
As another optional implementation, in order to further improve the accuracy of the identification, the method may further include: after the motor vehicle enters the vehicle identification area, identifying the number plate of the motor vehicle; because the image of the motor vehicle in the vehicle identification area can be clearly shot, and the license plate can be clearly seen, the license plate identification in the area is more accurate, and the problem that the motor vehicle license plate cannot be identified due to being shielded is solved. Then, the identified number plate is marked on the image of the motor vehicle, and the number plate synchronously follows the running track of the motor vehicle. Therefore, no matter the motor vehicle runs to any position, the number plate information of the motor vehicle can be determined in time, and real-time monitoring is facilitated.
As another optional implementation manner, in step S5, in the process of sending the first image, the second image, the third image and the tracking video information corresponding to the number to the violation database, number plate identification may be performed according to the first image; and then the identified number plate information is simultaneously sent to a violation database. In this embodiment, the number plate recognition may not be performed in the previous step, but the number plate of the vehicle may be recognized through the captured first image after the illegal parking behavior of the vehicle occurs, and then the recognized number plates may be transmitted to the illegal database together. In the scheme, the problems that the number plate is identified after the motor vehicle enters the vehicle identification, the data volume to be processed is large, and the redundant data is large can be avoided, and only the number plate of the vehicle with illegal behaviors needs to be identified, so that the data processing amount is reduced, and the utilization rate of the data is improved. As another implementation, the number plate may be identified according to one or a combination of several images of the second image or the third image or the vehicle image in the tracking video information separated from the original video information, or the identified number plate may be verified. For example, the number plate is identified through the first image, the verification is performed through the second image or the third image, if the number plate is consistent with the first image, the identified number plate is considered to be correct, and if the number plate is inconsistent with the first image, the image with the clear number plate is obtained from the tracking video information again for re-identification, so that the accuracy of the number plate identification is improved.
