Background
The ultra-low speed running on the expressway not only affects the overall running efficiency of the expressway, but also easily causes traffic accidents, because the rear vehicles meet the front ultra-low speed running vehicles suddenly under the condition of high speed running, and easily causes the rear drivers to be too late or cause rear-end collisions and other traffic accidents due to improper operation. Therefore, the ninth tenth provision of the road traffic safety law: when the driving motor vehicle is driven on the highway, the driving speed is lower than the speed of 20% or more of the specified minimum speed per hour, the penalty is 200 Yuan, and 3 points are paid. The minimum speed is specified to ensure that the front and rear vehicles run at the same speed as much as possible when the vehicles run on the expressway, so that the times of overtaking and lane changing are reduced, and the aim of reducing accidents is fulfilled. If the speed is lower than the lowest speed, the probability of rear-end accidents is increased.
In order to guarantee the safety of high-speed traffic and promote orderly traffic, the public security traffic management department sets the identifier of the lowest speed per hour at a high speed, and hopes that the speed of a motor vehicle is not lower than the lowest speed per hour in the driving process so as to avoid accidents such as rear-end collision and the like. In order to prevent the motor vehicle from running below the lowest speed per hour, various motor vehicle speed recording and detecting systems are developed by traffic management departments.

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 low-speed running illegal behaviors of a plurality of motor vehicles, which is used in a highway traffic control terminal. On the expressway, in order to ensure the safe passing of vehicles and avoid accidents such as rear-end collision and the like, the motor vehicles running on the expressway are limited to the lowest speed limit, and all the motor vehicles running on the expressway need to have the speed limit more than or equal to the requirement of the lowest speed limit except for the conditions of natural disasters or traffic abnormity and the like. The lowest speed limit sign is arranged on the high-speed road section, the motor vehicle is prohibited from running at the speed lower than the lowest speed per hour, however, the behavior that the motor vehicle runs at the speed lower than the lowest speed limit cannot be effectively prohibited only by the sign function, and meanwhile, the law enforcement difficulty of illegal low-speed running behaviors is increased. The method for recording the low-speed running illegal behaviors of the plurality of motor vehicles is used for timely and accurately recording the low-speed running illegal behaviors of the motor vehicles, warns motor vehicle drivers of complying with corresponding laws and regulations and maintains the traffic order of highways by forcefully supervising the low-speed running illegal behaviors of the motor vehicles.
As shown in fig. 1, the method for recording the law violation of low-speed driving 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 monitored road section.
And starting a video recording device arranged on the expressway to carry out video monitoring on the monitored road section, wherein the obtained monitoring video is used as original video information and is used as an original basis for subsequently judging the illegal behavior of the motor vehicle in low-speed running.
Step S2: the method comprises the steps of shooting a first image with a license plate number for each motor vehicle entering a motor vehicle identification area, numbering the motor vehicles, dividing original video information into multi-path tracking video information through a video separator, enabling each motor vehicle entering the motor 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 motor vehicle identification area, arranging the motor vehicle identification area on the road surface on an expressway, and enabling the video image recording equipment to accurately shoot the image of the motor vehicle entering the motor 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 motor vehicle identification area, the following modes can be adopted:
firstly, whether the image of the motor vehicle enters the image range of the motor vehicle identification area or not is monitored, and when the image of the motor vehicle enters the image range of the motor vehicle identification area, the motor vehicle is judged to enter the motor vehicle identification area. If the image of the motor vehicle does not exist in the motor vehicle identification area, the fact that no motor vehicle enters the motor vehicle identification area is indicated.
As another alternative embodiment, the process of determining whether the vehicle enters the vehicle identification zone may also be performed 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; when the motor vehicle enters the preset position of the radar detector, the motor vehicle is judged to enter the motor vehicle identification area.
When a motor vehicle enters a motor vehicle identification area, a first image of the motor vehicle with a license plate number is shot, as shown in fig. 2, when a traffic control terminal finds that the motor vehicle enters the motor vehicle identification area through a picture shot by a video image recording device or laser radar distance measurement, the motor vehicle is shot, and the image of the motor vehicle with a clear license plate number is shot as the first image. The accuracy of radar ranging is high, and as shown in fig. 3, after the radar identifies an image in the motor vehicle identification area, the video image is triggered to be recorded to shoot the image. Since the angle and the height of the video image recording device are adjusted according to the position of the motor vehicle identification area, the image of the motor vehicle, especially the number plate of the motor vehicle, can be clearly shot in the motor 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 the illegal behavior of low-speed running 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 the judgment of the illegal behavior. 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 motor vehicle identification area, the original video information is divided into a plurality of paths of tracking video information by the video separator, 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 motor vehicle tracked by the tracking video information is marked on the image of the motor vehicle, 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 during 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 motor 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 runs out of the monitoring range of the monitored road section, the monitoring range can be set according to requirements, can be a certain area which is easy to have low-speed running illegal behaviors, and is used for monitoring the low-speed running illegal behaviors 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 clearer driving track, is beneficial to observation and is beneficial to the subsequent recording of illegal low-speed driving behaviors.
Step S3: and judging whether the running speed of the motor vehicle tracked by the tracking video information is less than a preset lowest speed limit or not in the tracking video information.
And judging whether the running speed of the motor vehicle is less than the lowest speed limit required by the road section or not, determining according to the running distance of the motor vehicle in a certain time period in the tracking video information, and when the running distance of the motor vehicle in the certain time period is less than the distance running at the lowest speed limit in the certain time period, indicating that the current running speed of the motor vehicle is lower than the lowest speed limit, executing a step S4, otherwise, continuously monitoring the running condition of the motor vehicle.
Step S4: when the running speed of the motor vehicle is smaller than the preset lowest speed limit, whether the first distance between the motor vehicle and the front vehicle is larger than a preset first distance threshold value or not is judged.
When the motor vehicle runs at a speed lower than the preset lowest speed limit, the possible conditions include: under extreme weather conditions such as certain rain, snow, heavy fog and the like, the motor vehicle needs to run at a speed lower than the lowest speed limit for safety in running; due to traffic jam caused by traffic accidents and other reasons, the motor vehicle cannot run according to the normal speed per hour requirement; under normal conditions, the vehicle is illegally driven below the lowest speed limit. At this time, it is required to determine whether the first distance between the vehicle and the preceding vehicle is greater than a preset first distance threshold for normal driving on the highway, and when the first distance between the vehicle and the preceding vehicle is less than the preset first distance threshold, it indicates that the vehicle is driven at a speed lower than the lowest speed limit due to the influence of the preceding vehicle or the highway condition, and the like, and at this time, the vehicle does not belong to an illegal behavior of low-speed driving, and if the vehicle is not influenced by external factors, the first distance between the vehicle and the preceding vehicle is greater than the preset first distance threshold under a normal condition, it is determined that the vehicle belongs to the illegal behavior of low-speed driving, and step S5 is executed.
Step S5: and when the first vehicle distance is larger than a preset first distance threshold value, intercepting a second image of the motor vehicle with the marked number, which runs below the lowest speed limit, from the tracking video information.
When the first vehicle distance is larger than the preset first distance threshold value, the motor vehicle is judged to belong to the law violation of low-speed driving, as the law violation of low-speed driving of the motor vehicle is a continuous process, in order to guarantee the integrity of an evidence chain, a second image of the motor vehicle with the marked number, which is lower than the lowest speed limit, is intercepted from the tracking video information, and the time corresponding to the moment is simultaneously marked, and as the number of the corresponding motor vehicle is marked on the motor vehicle in advance and the motor vehicle runs along with the motor vehicle, the image with the number is intercepted as the second image when the image of the motor vehicle during law violation of low-speed driving is intercepted. Therefore, the illegal behavior of the motor vehicle in low-speed running can be clearly recorded through the second image, and the motor vehicle is conveniently identified in the tracking video information through the correspondence between the serial number and the motor vehicle.
Step S6: and sending the first image, the second image and the tracking video information to an illegal database.
The first image is shot in the motor 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 reflects the record of illegal low-speed running of the motor vehicle, the illegal information of the motor vehicle can be clearly reflected through the first image and the second image, and meanwhile, for the completeness of an evidence chain, the tracking video information containing the running track of the motor vehicle in the monitoring area is also sent together, so that the complete evidence chain is formed.
The method for recording the low-speed running illegal behaviors of the plurality of motor vehicles solves the problem of recording the low-speed running illegal behaviors at any position in real time in a monitoring range, realizes the recording of the low-speed running illegal behaviors of all the motor vehicles running in a monitored road section, can form all evidence chains of low-speed illegal running without manual operation, saves human resources and further improves the processing efficiency of the low-speed running illegal behaviors.
Specifically, in the embodiment of the present invention, when recording the illegal low-speed driving behaviors of the motor vehicles entering the vehicle identification area, one path of tracking video information needs to be separated from the original video information for each motor vehicle, so that a large amount of tracking video information is generated, in practice, only the tracking video information corresponding to the motor vehicle in which the illegal low-speed driving behaviors occur and the first image with the license plate number are concerned and retained, and therefore, as a further implementation manner, as shown in fig. 4, the method for recording the illegal low-speed driving behaviors of the plurality of motor vehicles further includes:
step S7: and when the first vehicle distance is larger than the preset first distance threshold, judging whether the second vehicle distance between the motor vehicle and the rear vehicle is smaller than the preset second distance threshold.
When the first distance between the motor vehicle and the front vehicle is greater than the first distance threshold, that is, the motor vehicle is in an illegal low-speed driving state, at this time, the motor vehicle is in a low-speed driving state, which easily affects normal driving of the rear vehicle and easily causes vehicle pressing, when the rear vehicle of the motor vehicle is driving at a higher hourly speed, traffic accidents such as rear-end collision also easily occur, in order to determine whether the illegal low-speed driving of the motor vehicle affects the rear vehicle, it is necessary to determine whether the second distance between the motor vehicle and the rear vehicle is smaller than a preset second distance threshold, when the second distance between the motor vehicle and the rear vehicle is larger than the preset second distance threshold, it is determined that the motor vehicle does not affect driving of the rear vehicle, otherwise, step S8 is executed.
Step S8: and when the second vehicle distance between the motor vehicle and the rear vehicle is smaller than a preset second distance threshold value, a third image containing the motor vehicle and the rear vehicle is intercepted from the tracking video information.
When the vehicle distance between the motor vehicle and the rear vehicle is smaller than the preset second distance threshold, it is described that the motor vehicle presses the motor vehicle running behind, the normal running of the rear vehicle is influenced, and a larger traffic influence is caused, and a third image containing the motor vehicle and the rear vehicle needs to be obtained from the tracking video information recording the running track of the motor vehicle, so that the acquisition of subsequent illegal evidence is facilitated, the real-time monitoring of the expressway by a high-speed traffic management department can be facilitated, and the step S9 is executed after the third image containing the motor vehicle and the rear vehicle is intercepted.
Step S9: and sending the third image to an illegal database.
And the third image containing the motor vehicle and the rear vehicle is sent to an illegal database, so that the acquisition of subsequent illegal evidence can be facilitated, and the real-time monitoring of a highway by a high-speed traffic management department can be facilitated.
As another further embodiment, as shown in fig. 5, the method for recording the law violation of low-speed driving of a plurality of motor vehicles further comprises:
step S10: when the motor vehicle enters the monitored road section, monitoring the speed, the first vehicle distance and the second vehicle distance of the motor vehicle in real time, and marking the speed, the first vehicle distance and the second vehicle distance on the tracking video information of the motor vehicle in real time.
When the motor vehicle enters the monitored road section, the running speed of the motor vehicle, the distance between the motor vehicle and the front vehicle and the distance between the motor vehicle and the rear vehicle are all the basis for judging whether the motor vehicle runs at the illegal low speed, so that the speed of the motor vehicle and the distances between the motor vehicle and the front vehicle and the rear vehicle need to be monitored in real time, the information is marked on the tracking video information in real time, the illegal low-speed running behavior of the motor vehicle can be accurately displayed through the tracking video information, and the follow-up inquiry of the illegal behavior evidence is facilitated.
As another further embodiment, as shown in fig. 6, the method for recording the law violation of low-speed driving of a plurality of motor vehicles further comprises:
step S11: and judging whether the motor vehicle runs out of the monitoring range. The monitoring range can be from the motor vehicle identification area to the end position of the lowest speed limit, so that the illegal low-speed driving behavior of the motor vehicle can be accurately identified. When the vehicle is driven out of the monitoring range, step S9 is executed, otherwise, the driving track of the vehicle in the tracking video information is continuously monitored.
Step S12: and judging whether a second image exists or not after the motor vehicle is driven out of the monitoring range.
If the motor vehicle has the illegal low-speed driving behavior, the second image is generated when the motor vehicle is in the illegal low-speed driving, so that if the second image is generated, the illegal low-speed driving behavior is shown, and if the second image is not generated, the illegal low-speed driving behavior is not shown. If the second image exists, step S13 is performed, otherwise step S14 is performed.
Step S13: when the second image is present, the tracking video information and the first image are stored.
If the motor vehicle has illegal low-speed driving behaviors, the tracking video information obtained by separating the separator needs to be stored, so that subsequent inquiry is facilitated.
Step S14: when the second image does not exist, the tracking video information and the first image are deleted.
If the second image does not exist, the motor vehicle does not illegally run at a low speed, and the illegal low-speed running behavior does not exist in the monitoring area. The tracking video information corresponding to the vehicle in the monitoring area is not 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. The traffic volume of vehicles on the expressway is very large, if data of all vehicles are reserved, a very large storage space is occupied, and traffic polices need to spend a great deal of time searching illegal information from the tracking video information, in the scheme, the motor vehicles enter a monitoring range to be monitored to obtain the tracking video information corresponding to the vehicles, after the motor vehicles exit the monitoring range, whether the illegal information exists in the motor vehicles is obtained by judging 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 a motor vehicle identification area, identifying the number plate of the motor vehicle; because the image of the motor vehicle in the motor 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 alternative embodiment, in step S6, in the process of sending the first image, the second image, and the tracking video information corresponding to the number to the violation database, the number plate may be identified according to the first image; and then the identified number plate information is simultaneously sent to a violation database. In this embodiment, the license plate identification may not be performed in the previous step, but the license plate of the vehicle may be identified by the captured first image after the vehicle has illegal low-speed driving behavior, and then the identified license 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 motor vehicle identification area, the data volume to be processed is large, and the redundant data is large can be avoided, the number plate of the vehicle with illegal behaviors is only required to be identified, the data processing amount is reduced, and the data utilization rate is improved. As other implementation schemes, the number plate can be identified according to one or a combination of several images in the second image or the motor vehicle image in the tracking video information, or the identified number plate can be verified.
