Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In order to better understand the technical solution provided by the embodiments of the present application and make the above objects, features and advantages of the embodiments of the present application more obvious, the technical solution in the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a flow chart of a vehicle detection method according to an embodiment of the present application is provided, wherein the vehicle detection method may be applied to a device with a vehicle detection function, such as an NVR (Network Video Recorder, network hard disk recorder) with a vehicle detection function, deployed in a video monitoring system of a gas station, and as shown in fig. 1, the vehicle detection method may include the following steps:
for convenience of description and understanding, the following description will take NVR as an example of the execution subjects of step S100 to step S130.
Step S100, detecting whether a vehicle enters a specified area of the gas station.
In the embodiment of the application, the designated area of the gas station may include an area in the gas station where the vehicle stop detection needs to be performed, for example, a refueling area of the gas station, that is, an area with a preset size on both sides of a refueling island.
In the embodiment of the application, the NVR can acquire the monitoring video of the designated area of the gas station through the front-end monitoring equipment (such as IPC (Internet Protocol Camera, webcam)) and detect whether the vehicle enters the designated area.
In one embodiment of the present application, the detecting whether the vehicle enters the designated area of the gas station may include:
and carrying out video analysis on the monitoring video of the designated area to determine whether the vehicle enters the designated area.
In this embodiment, the NVR may perform video analysis on the monitoring video of the designated area acquired by the front-end monitoring device to determine whether there is a vehicle entering the designated area.
In another embodiment of the present application, the detecting whether the vehicle enters the designated area may include:
and capturing images of the monitoring video of the designated area at fixed time, and analyzing the captured images to determine whether the vehicle enters the designated area.
In this embodiment, the NVR may capture a video of the surveillance of the designated area at regular time and analyze the captured image to determine whether there is a vehicle entry in the designated area.
In still another embodiment of the present application, the detecting whether a vehicle enters the designated area may include:
when the oil gun is detected to be lifted, capturing images of the monitoring video of the designated area, and analyzing the captured images to determine whether a vehicle enters the designated area.
In this embodiment, the NVR may be triggered to capture the surveillance video of the designated area by detecting that the gun is lifted.
For example, whether the oil gun is lifted or not may be detected by video analysis of a monitoring video of a designated area.
Or alternatively, the process may be performed,
the specific sensors can be arranged on the oiling machine and the oil gun, when the oil gun is lifted, the oiling machine can send a capture triggering instruction to the NVR, and the NVR is triggered to capture the monitoring video of the designated area; when the NVR receives the grip trigger command, it may be determined that the gun is lifted.
Correspondingly, when the NVR detects that the oil gun is lifted, capturing a monitoring video of the designated area, and analyzing the captured image to determine whether a vehicle enters the designated area.
It should be noted that, in the embodiment of the present application, the scheme for detecting whether the vehicle enters the designated area described in the above embodiment may be implemented simultaneously in multiple ways, so as to reduce the occurrence of missed detection and improve the accuracy of vehicle detection.
For example, the NVR may detect whether a vehicle enters the specified area by performing video analysis on the surveillance video of the specified area on one hand, and detect whether a vehicle enters the specified area by capturing images of the surveillance video of the specified area at regular time and analyzing the captured images on the other hand.
For another example, the NVR may detect whether the vehicle enters the specified area by performing video analysis on the surveillance video of the specified area on one hand, and detect whether the vehicle enters the specified area by performing capture on the surveillance video of the specified area and analyzing the captured image when receiving the capture trigger command on the other hand.
Step S110, when the target vehicle is detected to enter a designated area, acquiring vehicle attribute information of the target vehicle; wherein the vehicle attribute information includes license plate information.
In the embodiment of the present application, the target vehicle does not refer to a fixed vehicle, but may refer to any vehicle that is detected to enter the command area, and the present application will not be repeated.
In the embodiment of the application, when the NVR detects that the target vehicle enters the designated area, the NVR can acquire the vehicle attribute information of the target vehicle.
The vehicle attribute information may include license plate information (e.g., license plate number), among others.
It should be noted that, in the embodiment of the present application, the vehicle attribute information is not limited to include license plate information, and may include other attribute information such as a vehicle body color, a vehicle brand, a model, and the like.
In one embodiment of the present application, the acquiring the vehicle attribute information of the target vehicle may include:
and receiving the vehicle attribute information of the target vehicle sent by the monitoring front-end equipment.
In this embodiment, when the monitoring front-end device includes a monitoring device having a vehicle detecting and analyzing function, the monitoring device having a vehicle detecting and analyzing function may also detect whether a vehicle enters the designated area, and when it is detected that the target vehicle enters the designated area, the monitoring device may take a snapshot of the target vehicle and analyze the snapshot picture to obtain vehicle attribute information of the target vehicle, and send the vehicle attribute information of the target vehicle to the NVR.
In another embodiment of the present application, the acquiring the vehicle attribute information of the target vehicle may include:
acquiring a vehicle picture of a target vehicle;
and analyzing the vehicle picture of the target vehicle to obtain the vehicle attribute information of the target vehicle.
In this embodiment, when the NVR detects that the target vehicle enters the specified area, the NVR may acquire a vehicle picture of the target vehicle.
In one example, the acquiring the vehicle picture of the target vehicle may include:
and receiving a vehicle picture of the target vehicle sent by the monitoring front-end equipment.
In this example, when the monitoring front-end device includes a monitoring device having a vehicle detection and snapshot function, the monitoring device having a vehicle detection and snapshot function may snapshot the target vehicle to obtain a vehicle picture of the target vehicle when detecting that the target vehicle enters the designated area, and send the vehicle picture of the target vehicle to the NVR.
In another example, the acquiring the vehicle picture of the target vehicle may include:
and capturing a vehicle picture of the target vehicle when the target vehicle is determined to enter the designated area according to the monitoring video of the designated area.
In this example, when the NVR supports the surveillance video-based vehicle analysis function, the NVR may capture a vehicle picture of the target vehicle when it is determined that the target vehicle enters the instruction area according to the surveillance video of the specified area.
In this embodiment, when the NVR obtains the vehicle picture of the target vehicle, the vehicle picture of the target vehicle may be analyzed to obtain the vehicle attribute information of the target vehicle.
It should be noted that, in the embodiment of the present application, the NVR receiving the vehicle attribute information of the target vehicle sent by the monitoring front-end device and the NVR analyzing the vehicle picture of the target vehicle to obtain the vehicle attribute information of the target vehicle may be implemented simultaneously.
In this case, the NVR receives the vehicle attribute information (referred to herein as first vehicle attribute information) of the target vehicle transmitted from the monitoring front-end device, and obtains the vehicle attribute information (referred to herein as second vehicle attribute information) of the target vehicle by analyzing the vehicle picture of the target vehicle, and may directly determine the first vehicle attribute information as the vehicle attribute information of the target vehicle, or the NVR may directly determine the second vehicle attribute information as the vehicle attribute information of the target vehicle; alternatively, the NVR may combine the first vehicle attribute information and the second vehicle attribute information.
For example, the NVR may compare the first vehicle attribute information and the second vehicle attribute information of the target vehicle; adding attribute information which exists in the first vehicle attribute information but does not exist in the second vehicle attribute information to the vehicle attribute information of the target vehicle; adding the vehicle attribute information in the second vehicle attribute information to the vehicle attribute information of the target vehicle for the vehicle attribute information existing in both the first vehicle attribute information and the second vehicle attribute information; and adding the vehicle attribute information which does not exist in the first vehicle attribute information but exists in the second vehicle attribute information to the vehicle attribute information of the target vehicle, and further obtaining the vehicle attribute information of the target vehicle.
Step S120, periodically detecting whether the target vehicle is staying in the designated area.
In the embodiment of the application, after the NVR detects that the target vehicle enters the designated area, the NVR can also detect whether the target vehicle stays in the designated area or not at regular time.
In one embodiment of the present application, the above-described timing detection of whether the target vehicle stays in the designated area may include:
capturing images of the monitoring video of the designated area at regular time, and analyzing the captured images;
when a vehicle exists in a designated area, acquiring vehicle attribute information of the vehicle;
if the vehicle attribute information is matched with the vehicle attribute of the target vehicle, determining that the target vehicle stays in a designated area;
and if the vehicle attribute information is not matched with the vehicle attribute of the target vehicle, determining that the target vehicle leaves the designated area.
In this embodiment, the NVR may periodically capture a surveillance video of the designated area and analyze the captured image to determine whether a vehicle is present in the designated area.
In this embodiment, when the NVR determines that the vehicle exists in the specified area, the NVR may acquire the vehicle attribute information of the vehicle and determine whether the vehicle attribute information of the vehicle matches the vehicle attribute information of the target vehicle.
When the license plate number of the vehicle is the same as that of the target vehicle, determining that the vehicle attribute information of the vehicle is matched with the vehicle attribute information of the target vehicle; otherwise, it is determined that the vehicle attribute information of the vehicle does not match the vehicle attribute information of the target vehicle.
In this embodiment, when the NVR determines that the vehicle attribute information of the vehicle matches the vehicle attribute information of the target vehicle, the NVR may determine that the target vehicle stays in the specified area;
when the NVR determines that the vehicle attribute information of the vehicle does not match the vehicle attribute information of the target vehicle, the NVR may determine that the target vehicle leaves the designated area.
In this embodiment, when the NVR detects that there is no vehicle in the designated area, the NVR may also determine that the target vehicle leaves the designated area.
Step S130, when the target vehicle is determined to leave the designated area, the residence time of the target vehicle in the designated area is determined.
In the embodiment of the application, when the NVR determines that the target vehicle leaves the designated area, the NVR can determine the stay time of the target vehicle in the designated area.
For example, the NVR may determine the time between when the target vehicle is detected to enter the specified area and when the target vehicle is determined to leave the specified area as the residence time of the target vehicle in the specified area.
In order to enable those skilled in the art to better understand the technical scheme provided by the embodiment of the present application, the technical scheme provided by the embodiment of the present application is described below in connection with a specific application scenario.
Fig. 2 is a schematic architecture diagram of a specific application scenario provided in an embodiment of the present application. As shown in fig. 2, the application scenario may include an NVR, a platform, an intelligent vehicle snapshot machine, and/or a non-intelligent IPC (in the figure, an intelligent vehicle snapshot machine and a non-intelligent IPC are taken as examples), and a fuel dispenser.
The NVR supports access of a non-intelligent IPC and an intelligent vehicle snapshot machine, for the intelligent vehicle snapshot machine, the NVR supports reporting of vehicle detection information (vehicle attribute information and vehicle pictures), for the non-intelligent IPC, the NVR supports analysis of whether a vehicle enters a designated area (comprising any one of areas A, B, C and D) according to the transmitted code stream information, namely, the NVR supports vehicle analysis based on DSP code streams.
When the NVR detects that a vehicle enters a designated area through the DSP module, the acquired vehicle picture is sent to the analysis module, and vehicle attribute information (including license plate information, vehicle body color, vehicle brand, vehicle type and the like) is analyzed by the analysis module.
The NVR also supports timed capture, i.e., capturing a surveillance video at a fixed time, and analyzing the captured image by an analysis module to determine whether a vehicle is present to enter a designated area.
The fuel dispenser may trigger the NVR to pick up a picture (referred to herein as a manual pick up) when it detects that the gun is lifted; the NVR may analyze the captured picture by an analysis module to determine if there is a vehicle entering the designated area.
When the NVR determines that the vehicle exists in the designated area, the monitoring video is captured regularly, and vehicle attribute information of the vehicle in the designated area is acquired through an analysis module.
When the NVR detects a first license plate information in the designated area (the license plate information can be sent to the NVR by an intelligent snapshot machine, can also be obtained by analyzing the NVR based on DSP code rate, or can be obtained by analyzing the NVR by means of timing or manual capture), the NVR can upload the vehicle attribute information of the vehicle to the platform.
When the NVR determines that the vehicle is leaving the designated area, the vehicle's residence time within the designated area may also be uploaded to the platform.
Based on the application scenario shown in fig. 2, the implementation flow of the vehicle detection scheme provided by the embodiment of the application includes:
1. no vehicles in designated area
On one hand, the NVR detects whether a vehicle enters a specified area in a manner based on DSP code stream analysis; on the other hand, whether the vehicle enters the designated area or not is detected by means of a timing diagram.
The timing diagram grabbing mode and the DSP code stream analysis mode form complementary detection, and missing detection after a vehicle enters an area is avoided.
2. Vehicle entering designated area
The intelligent snapshot machine captures that the vehicle enters the specified area, or/and the NVR detects that the vehicle enters the specified area based on DSP code stream analysis, or/and the NVR detects that the vehicle enters the specified area based on timing snapshot analysis.
When the NVR detects that the vehicle enters the specified area through any mode, the NVR acquires the vehicle attribute information of the vehicle entering the specified area and uploads the acquired vehicle attribute information to the platform.
When the NVR detects that the vehicle enters the specified area by two or three means, it is necessary to determine whether the vehicle attribute information of the vehicle has been uploaded or not after acquiring the vehicle attribute information of the vehicle entering the specified area before uploading the vehicle attribute information.
If so, judging whether the difference between the current time and the time of uploading the vehicle attribute information of the vehicle last time is larger than an alarm uploading interval (such as 5 minutes); if the vehicle attribute information is larger than the vehicle attribute information, uploading the vehicle attribute information to a platform; if the vehicle attribute information is smaller than or equal to the vehicle attribute information, uploading the vehicle attribute information of the vehicle is refused.
If not, uploading the vehicle attribute information of the vehicle.
3. Vehicle is not refueled
If the vehicle enters the designated area without refueling and the vehicle is detected, a parking analysis mechanism is triggered, the NVR continuously and periodically grasps the image to analyze whether the vehicle in the designated area exists or not, and the judgment condition is that the license plate information detected in the designated area is continuously the license plate information of the vehicle.
And uploading the vehicle attribute information of the vehicle according to the minimum alarm uploading interval every time the NVR detects that the license plate information is the vehicle attribute information of the license plate information of the vehicle.
4. Vehicle refueling
If the vehicle stays in the designated area and requires refueling, triggering the NVR to capture images when the oil gun is lifted, and then analyzing the attribute information of the vehicle on the captured images.
If the analyzed vehicle attribute information (mainly license plate information) is not matched with the previously detected vehicle attribute information, uploading the vehicle attribute information to a platform; if the analyzed vehicle attribute information is matched with the previously detected vehicle attribute information, judging whether the difference between the current time and the time of uploading the vehicle attribute information is larger than the minimum alarm interval or not.
If the vehicle attribute information is larger than the vehicle attribute information, uploading the vehicle attribute information; otherwise, the uploading of the vehicle attribute information is refused.
5. The vehicle stays in the designated area
If the vehicle enters the designated area and is completely filled with oil and the vehicle is detected, a parking analysis mechanism is triggered, the NVR continuously and periodically grasps the image to analyze whether the vehicle in the designated area exists or not, and the judgment condition is that the license plate information detected in the area is continuously the license plate information of the vehicle.
And uploading a parking alarm according to the minimum parking alarm interval when the vehicle in the appointed area exists, and informing the platform that the vehicle stays in the appointed area continuously.
6. The vehicle leaves the designated area
When the NVR detects that no vehicle exists in the appointed area or the vehicle exists in the appointed area, but the license plate information of the vehicle is different from the license plate information detected last time, the vehicle is determined to leave the appointed area, and at the moment, the NVR uploads the vehicle to the platform to leave, and the residence time of the vehicle in the appointed area is uploaded.
In the embodiment of the application, whether the target vehicle stays in the designated area or not is detected by detecting whether the vehicle enters the designated area of the gas station, and when the target vehicle is detected to enter the designated area, the vehicle attribute information of the target vehicle is acquired and whether the target vehicle stays in the designated area is detected at regular time; when the target vehicle is determined to leave the designated area, the residence time of the target vehicle in the designated area is determined, so that the real-time detection of the residence time of the vehicle in the designated area of the gas station is realized, and the efficiency of statistics of the residence time of the vehicle in the gas station is improved.
