Description
Technical Field
The invention relates to the technical field of public security traffic management, in particular to a method and a device for recording low-speed driving illegal behaviors of a motor vehicle.
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.

The method ensures that some motor vehicles follow a law when running near the camera device, and the motor vehicles can run at will without looking at the lowest speed limit when the motor vehicles are far away from the camera device, thereby causing the problem of traffic jam caused by the centered driving behaviors such as mobile phone hitting of motor vehicle drivers.

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 low-speed driving illegal behaviors of a motor vehicle, 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 driving illegal behaviors of the motor vehicle is used for timely and accurately recording the low-speed driving illegal behaviors of the motor vehicle, and warns a motor vehicle driver to comply with corresponding laws and regulations and maintain the traffic order of a highway by forcefully monitoring the low-speed driving illegal behaviors of the motor vehicle.
As shown in fig. 1, the method for recording the illegal behavior of low-speed driving of the motor vehicle comprises the following steps:
step S1: and judging whether the motor vehicle enters a motor vehicle identification area.
On the expressway, a motor vehicle identification area is arranged on the road surface, and after the motor vehicle identification area identifies the vehicle, the low-speed driving illegal behaviors of the vehicle are accurately captured. By adjusting the height and the angle of the video image recording equipment arranged at the intersection, the video image recording equipment can accurately shoot the image of the motor vehicle entering the motor vehicle identification area. When the motor vehicle runs into the motor vehicle identification area, the traffic control terminal judges whether the motor vehicle enters the motor vehicle identification area, if so, the step S2 is executed, if the motor vehicle does not enter the motor vehicle identification area, the motor vehicle identification area is continuously monitored until a vehicle enters the motor vehicle identification area.
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; and when the motor vehicle reaches the position of the motor vehicle identification area preset by the radar detector, judging that the motor vehicle enters the motor vehicle identification area. The accurate distance of the motor vehicle from the intersection can be known through radar ranging, the distance corresponds to the distance of the lowest speed-limiting road section, a region before the motor vehicle runs to the lowest speed-limiting road section is set as a motor vehicle identification region, and after the motor vehicle reaches the preset position, the motor vehicle is judged to enter the motor vehicle identification region.
Step S2: when the motor vehicle enters the motor vehicle identification area, a first image of the motor vehicle with the license plate number is shot, the motor vehicle is numbered, the number is marked on the motor vehicle and synchronously follows the running track of the motor vehicle, as shown in figure 2, and simultaneously, video image recording equipment corresponding to the number is started to record the video image of the running track of the motor vehicle.
When the traffic control terminal finds that a motor vehicle enters a motor vehicle identification area through a picture shot by the video image recording device or laser radar distance measurement, the motor vehicle is shot, 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 motor vehicle identification area, the radar triggers the video image recording device to shoot the image. Because the angle and the height of the video image recording device at the intersection 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. Then numbering the motor vehicle, and then starting a video image recording device on the expressway to record the video image of the driving track of the motor vehicle, wherein the motor vehicle corresponds to the video image recording device through the numbering. In addition, the serial number is also marked on the image of the motor vehicle, and the serial number synchronously follows the running track of the motor vehicle, so that the corresponding serial number is displayed in a video picture in the running process of the motor vehicle, which motor vehicle can be clearly known according to the serial number, and the serial number is numbered according to the sequence of the motor vehicles, so that a complex data processing process is not needed, the serial number is marked on the motor vehicle for synchronous following, the license plate number does not need to be identified by spending more time in vehicle identification, a visible unique identifier is formed for each vehicle, and the data processing amount is reduced. The corresponding video image recording equipment tracks the running track of the motor vehicle in real time until the motor vehicle runs out of the monitoring range, and the monitoring range can be set as required. Therefore, each video image recording device tracks one motor vehicle, the number of the video image recording devices can be set properly according to the lanes and the monitoring range, and the tracking accuracy is improved.
Step S3: and judging whether the running speed of the motor vehicle is less than a preset lowest speed limit or not.
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 recorded video image, 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, a second image of the motor vehicle with the marked number running below the lowest speed limit is intercepted from the video image.
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 driving, needs to be intercepted from a video image, and the time corresponding to the moment is marked. Therefore, the illegal behavior of the motor vehicle in low-speed running can be clearly recorded through the second image, and the motor vehicle can be conveniently identified in the video image through the correspondence between the serial number and the motor vehicle.
Step S6: and sending the first image, the second image and the video image 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, the video of the running track of the motor vehicle in the monitoring area is also sent together for the completeness of an evidence chain, so that the complete evidence chain is formed.
The method for recording the low-speed driving illegal behaviors of the motor vehicle, provided by the embodiment of the invention, solves the problem of recording the low-speed driving illegal behaviors at any position in real time in a monitoring range, can form all evidence chains of low-speed illegal driving without manual operation, saves human resources and further improves the processing efficiency of the low-speed driving illegal behaviors.
As another further embodiment, as shown in fig. 4, the method for recording the illegal behavior of low-speed driving of the motor vehicle further comprises:
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, acquiring a third image containing the motor vehicle and the rear vehicle from the video image.
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 video image recording the running track of the motor vehicle, so that the acquisition of subsequent illegal evidence is facilitated, and a highway management department can conveniently monitor the highway in real time, and after the third image containing the motor vehicle and the rear vehicle is obtained, the step S9 is executed.
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 illegal behavior of low-speed driving of the motor vehicle further comprises:
step S10: when the motor vehicle enters a motor vehicle identification area, 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 a video image of the motor vehicle in real time.
After the motor vehicle enters the motor vehicle identification area, 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 a video image in real time, the illegal low-speed running behavior of the motor vehicle can be accurately displayed through the video image, 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 illegal behavior of low-speed driving of the motor vehicle 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 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 video image and the first image are stored.
If the motor vehicle has illegal low-speed driving behaviors, the video image of the motor vehicle shot by the video image recording device needs to be stored, so that subsequent inquiry is facilitated.
Step S14: and when the second image does not exist, deleting the video image and the first image.
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 images in the monitoring area are not required to be reserved, so that the video images can be deleted, the storage space is saved, and the utilization efficiency of the storage equipment 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 manually search illegal information from the video images, a large amount of time is also spent, in the scheme, the motor vehicles are monitored in the monitoring range, after the motor vehicles are driven out of the monitoring range, whether the motor vehicles have the illegal information is obtained through judgment of the illegal information, if the illegal information does not exist, the videos are deleted, if the illegal information exists, the videos are uploaded to the 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 the data center or a receiving platform to provide more traffic data information. 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 the video images 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 manner, in step S2, 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, the license plate of the vehicle may not be identified in step S2, but in step S6, the license plate identification may be performed according to the first image in the process of sending the first image, the second image and the video image recorded by the video image recording device corresponding to the number to the illegal database; 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 another implementation, the number plate may be identified based on one or a combination of several images of the vehicle in the second image or the recorded video image, 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, 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 recorded video image again for re-identification, so that the accuracy of license plate identification is improved.
