The first embodiment is as follows:
referring to fig. 1, a method for detecting a vehicle speed limit provided in an embodiment of the present application is described below, where the method for detecting a vehicle speed limit in the embodiment of the present application includes:
s101, carrying out real-time intersection detection on first video information acquired by a first vehicle-mounted camera;
in the embodiment of the application, a first vehicle-mounted camera can be arranged on a vehicle, and the first vehicle-mounted camera is used for acquiring first video information.
The vehicle speed limit detection device carries out real-time intersection detection on the first video information and detects whether an intersection area appears in the first video information in real time.
Step S102, if an intersection area is detected in the first video information, acquiring the vehicle speed of preset time;
the vehicle speed limit detection means indicates that the vehicle has approached the intersection if the intersection area is detected in the first video information. According to the regulations of traffic laws, vehicles should slow down in the intersection area.
At this time, the vehicle speed for a preset time may be acquired. The preset time may be set according to circumstances.
In some embodiments, the preset time may be a point in time when the intersection region disappears. When the intersection area disappears, the vehicle is passing through the intersection area, and the acquired vehicle speed is the speed of the vehicle passing through the intersection area.
In other embodiments, the preset time may be other time points, for example, the preset time point may be a time point N1 seconds after the intersection region is detected, and assuming that the intersection region is detected at time point T1, the preset time may be time point T1+ N1, where N1 is a user-defined value greater than or equal to 0.
In other embodiments, the preset time may also be a time period, for example, assuming that the starting point of the time period is a time point N2 seconds after the intersection region is detected, the ending point of the time period is a time point N3 seconds after the intersection region is detected, assuming that the intersection region is detected at a time point T1, the preset time may be [ T1+ N2, T1+ N3], N2 and N3 are user-defined values greater than or equal to 0, and N3 is greater than or equal to N2. At this time, the vehicle speed at the preset time may be an average speed or a maximum speed within a preset time period.
And step S103, if the vehicle speed is greater than a preset vehicle speed threshold value, violation alarming operation is executed.
Further, the method further comprises:
a1, carrying out real-time intersection detection on second video information acquired by a second vehicle-mounted camera, wherein the focal length of the second vehicle-mounted camera is greater than that of the first vehicle-mounted camera;
in some possible implementations, a second vehicle-mounted camera may also be provided on the vehicle. The focal length of the second vehicle-mounted camera is larger than that of the first vehicle-mounted camera.
The first vehicle-mounted camera is short in focal length and short in shooting distance, and is mainly used for detecting whether a vehicle is close to a crossing area or not and determining the time for detecting the speed of the vehicle. The second vehicle-mounted camera is long in focal length and long in shooting distance, so that the intersection area can be found earlier, and a driver of the vehicle is prompted to slow down and walk slowly.
Therefore, the vehicle speed limit detection device can carry out real-time intersection detection on the second video information acquired by the second vehicle-mounted camera and judge whether the vehicle is about to reach an intersection area.
And A2, if the intersection area is detected in the second video information, executing deceleration prompting operation.
If the vehicle speed limit detection device detects the intersection area in the second video information, the vehicle is indicated to be about to arrive at the intersection area, and at the moment, the deceleration prompting operation can be executed to prompt a vehicle driver to decelerate and slowly move, so that violation of traffic regulations is avoided.
When real-time intersection detection is carried out, intersection detection can be carried out in a mode of detecting intersection markers. The crossing markers can be selected according to actual conditions, for example, crossing markers such as zebra stripes and traffic lights can be selected for crossing detection.
In the embodiment of the application, the zebra crossing can be selected as the crossing marker, and crossing detection is performed in a zebra crossing detection mode.
Correspondingly, the real-time intersection detection of the first video information collected by the first vehicle-mounted camera comprises the following steps:
b1, carrying out real-time zebra crossing detection on the first video information acquired by the first vehicle-mounted camera;
when the zebra crossing is selected as the crossing marker, real-time zebra crossing detection can be performed on first video information acquired by a first vehicle-mounted camera.
B2, if the zebra crossing is detected in the first video information, determining that the crossing area is detected in the first video information.
If the zebra crossing is detected in the first video information, the crossing area is detected.
Correspondingly, the real-time intersection detection of the second video information acquired by the second vehicle-mounted camera comprises the following steps:
c1, carrying out real-time zebra crossing detection on second video information acquired by a second vehicle-mounted camera;
when the zebra crossing is selected as the crossing marker, real-time zebra crossing detection can be performed on second video information acquired by the second vehicle-mounted camera.
C2, if the zebra crossing is detected in the second video information, determining that the crossing area is detected in the second video information.
And if the zebra crossing is detected in the second video information, the crossing area is detected.
It should be understood that, in the above-described embodiment, the content of the violation warning operation may be set according to actual conditions. In some possible implementations, the performing violation alerting operations includes:
d1, uploading the first video information in the first preset time period to the management and control platform.
The first preset time period can be set according to actual conditions. For example, the first preset time period may be a time period from N4 seconds before the violation alarm is triggered to N5 seconds after the violation alarm is triggered, and assuming that the violation alarm is triggered at a time point of T2, the first preset time period may be [ T2-N4, T2+ N5 ].
When violation alarming operation is executed, the first video information in the first preset time period can be uploaded to the management and control platform as evidence. The staff can look over the first video information in first preset time quantum on the management and control platform, recheck whether the driver's action is violating, and can regard the first video information in first preset time quantum as the foundation of punishing education driver.
In other possible implementations, the performing violation alerting operations includes:
and E1, setting the editing state of the first video information in the second preset time period to be a non-editing state.
When the network state of the vehicle is not good, the vehicle may not be able to upload the first video information in the first preset time period to the management and control platform in time. In order to avoid the vehicle driver from deleting or tampering the first video information within the first preset time period, the editing state of the first video information within the second preset time period may be set to a non-editable state.
The second preset time period can be set according to actual conditions. In some possible implementations, the second preset time period may coincide with the first preset time period.
After the editing state of the first video information in the second preset time period is set to be the non-editable state, the vehicle driver does not have the right to delete or tamper the first video information in the non-editable state, and therefore evidence is kept.
The first video information may or may not be uploaded, for example, under the condition that the network state is good, the first video information in a first preset time period may be uploaded to the management and control platform; under the condition that the network state is bad, the first video information in the first preset time period can not be uploaded to the control platform, the first video information in the second preset time period is latched, and after the driving is finished, the worker directly reads the first video information in the second preset time period in the uneditable state from the vehicle speed limit detection device.
Besides the violation alarming operation, the vehicle driver can be warned in the modes of sound-light alarming, buzzer alarming, loudspeaker alarming, vibration alarming and the like.
In this embodiment, violation alarm operations such as uploading videos and video latching are adopted, and the violation alarm operations can interact with the management and control platform, so that evidence of violation of the vehicle driver can be stored, and the violation of the vehicle driver can be conveniently rechecked by the staff and can be used as a basis for punishing the vehicle driver. Meanwhile, in the embodiment, the vehicle driver is only warned through the violation warning operation, so that behaviors such as vehicle deceleration and the like cannot be forcibly executed, the driving operation of the vehicle driver is prevented from being influenced, the driving safety of the vehicle is improved, and the conflict psychology of the driver can be reduced.
In the vehicle speed limit detection method provided by the embodiment, the first video information acquired by the first vehicle-mounted camera is subjected to real-time intersection detection, and if an intersection area is detected in the first video information, it is indicated that the vehicle is close to the intersection area, and at this time, the vehicle speed of the preset time can be acquired. If the vehicle speed is greater than the preset vehicle speed threshold value, the condition that a vehicle driver does not decelerate and crawl at the intersection according to the regulations of traffic regulations is indicated, violation alarming operation is executed, when the vehicle intersection speed is detected, the camera is installed on the vehicle, the camera does not need to be installed at each intersection, the installation cost and the installation workload are reduced, in addition, whether the vehicle reaches the intersection or not is identified through the image processing technology, compared with a GPS positioning mode, the problems of less environmental interference and no positioning drift exist, and the problems that the cost is high, the workload is large, the accuracy is low and false detection alarm is easy to trigger in the conventional vehicle intersection deceleration detection technology are solved.
In addition, a second vehicle-mounted camera can be further arranged, the focal length of the second vehicle-mounted camera is larger than that of the first vehicle-mounted camera, so that the shooting distance of the second vehicle-mounted camera is larger than that of the first vehicle-mounted camera, the intersection area can be found earlier, and the vehicle driver is prompted to slow down. The first vehicle-mounted camera and the second vehicle-mounted camera are matched with each other, so that the violation behaviors of a vehicle driver can be found, the vehicle driver can be reminded before the violation behaviors occur, and the violation behaviors are reduced.
When the intersection is detected, a proper intersection marker can be selected for detection. In this embodiment, the zebra crossing can be selected as the crossing marker, and crossing detection is performed by detecting the zebra crossing. And if the zebra crossing is detected in the first video information or the second video information, judging that the crossing area is detected.
And when the vehicle driver breaks the violation, triggering violation alarming operation. The violation alarming operation can be that the first video information in the first preset time period is uploaded to the management and control platform, the editing state of the first video information in the second preset time period is set to be a non-editable state, and the vehicle driver can be warned in the modes of sound-light alarming, buzzer alarming, loudspeaker alarming, vibration alarming and the like. Through the violation alarming operation in the embodiment, information synchronization and evidence latching can be performed with the control platform, so that a worker can recheck the violation behavior of a vehicle driver according to the first video information in the first preset time period or the video information in the second preset time period, and the video information is used as a basis for punishing and educating the vehicle driver.
