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 application 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 make the technical solutions provided in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a schematic flow chart of a vehicle flushing detection method according to an embodiment of the present application is shown in fig. 1, where the vehicle flushing detection method may include the following steps:
step S100, when it is detected that a vehicle of a specified type leaves the worksite, it is detected whether the vehicle passes through a flushing area. If yes, go to step S110; otherwise, go to step S120.
In the embodiment of the application, in order to realize automatic detection of vehicle washing, video monitoring can be carried out on vehicles entering and leaving a construction site.
When it is detected that a vehicle enters the monitored area, it may be determined that the vehicle is entering the worksite or leaving the worksite.
In one example, the detecting that the vehicle leaves the worksite may include:
when the vehicle is detected to enter the monitoring area, detecting the head and the tail of the vehicle;
and if the vehicle head is detected, determining that the vehicle leaves the construction site.
For example, when it is detected that the vehicle enters the monitoring area, the detection of the head and the tail of the vehicle can be performed on the vehicle, that is, whether the vehicle faces the monitoring person in the monitoring picture or the monitoring person in the tail direction is detected.
And if the detection result is that the vehicle head is the vehicle head (namely the vehicle head faces the monitoring personnel in the monitoring picture), determining that the vehicle leaves the construction site.
For example, if the detection result is the vehicle tail (i.e., the vehicle tail faces the monitoring person in the monitoring picture), it is determined that the vehicle enters the construction site.
In one example, when a vehicle is detected entering a worksite, a normal event may be generated to record the vehicle entering the worksite, which may include a snapshot of the vehicle.
It should be noted that, in this example, when the video monitoring front end is erected, it is ensured that the vehicle head faces the video monitoring front end when entering the monitoring screen when the vehicle leaves the building site, but the manner of erecting the video monitoring front end in the embodiment of the present application is not limited thereto, that is, the video monitoring front end may be erected in a manner that the vehicle tail faces the video monitoring front end when entering the monitoring screen when the vehicle leaves the building site, and the specific implementation thereof is not limited herein.
For convenience of description and understanding, the way in which the vehicle head faces the front end of the video surveillance when entering the surveillance screen is taken as an example in the following description when the vehicle leaves the construction site.
In the embodiment of the application, when the vehicle is detected to leave the construction site, the type detection can be carried out on the vehicle so as to determine whether the vehicle is a specified type of vehicle.
For example, the specific type of vehicle may be a vehicle (e.g., a construction vehicle such as a muck truck, a concrete mixer truck, etc.) that needs to be cleaned when leaving the work site, or the like.
In the embodiment of the present application, the type of the vehicle that needs to be subjected to the vehicle flushing detection (i.e., the above-specified type) is not limited to the engineering vehicle such as the slag car and the concrete mixer, but may include other types determined according to actual requirements, and the embodiment of the present application is not limited thereto.
Further, when the type of the vehicle is detected as a non-specified type, a normal event may be generated to record an event that the non-specified type of vehicle leaves the worksite, and the normal event may include a snapshot of the vehicle.
When it is detected that the type of the vehicle is a specified type, it is necessary to further detect whether the vehicle of the specified type passes through the flushing area.
For example, the position of the flushing area may be set in the monitoring screen in advance, and when it is detected that the vehicle enters the monitoring screen, it may be further detected whether the vehicle passes through the flushing area.
In one example, it may be determined whether the vehicle has passed through the wash zone by detecting the lane in which the vehicle left the worksite.
For example, considering that in a practical scenario, multiple lanes may exist at a worksite entrance and exit, and a flushing area may not exist in some of the lanes (i.e., no vehicle flushing device is deployed), when a vehicle of a specified type is detected to leave the worksite, the lane in which the vehicle is located may be detected.
If the lane where the vehicle is located is detected as the lane where the flushing area is located (namely, the vehicle flushing device is deployed in the lane), it is determined that the vehicle passes through the flushing area, and the time that the vehicle is located in the flushing area can be further counted.
And if the detected lane where the vehicle is located is not the lane where the flushing area is located, determining that the vehicle does not pass through the flushing area.
Step S110, whether an alarm is generated or not is determined according to the time when the vehicle is in the flushing area, and the alarm is used for indicating that the flushing time is insufficient.
In the embodiment of the application, when it is detected that the vehicle passes through the flushing area, the time that the vehicle is in the flushing area can be counted, and whether to generate the alarm is determined based on the time that the vehicle is in the flushing area.
In one possible embodiment, the time that the vehicle is in the wash zone is determined by:
when the fact that the vehicle enters the flushing area is detected, capturing the vehicle to obtain a first captured image of the vehicle;
when the vehicle is detected to leave the flushing area, capturing the vehicle to obtain a second captured image of the vehicle;
and counting the time length of the vehicle passing through the flushing area according to the snapshot time of the first snapshot picture and the snapshot time of the second snapshot picture.
For example, the vehicle may be captured when the vehicle is detected to enter the flushing area and the vehicle is detected to leave the flushing area, respectively, to obtain captured images of the vehicle (referred to as a first captured image and a second captured image, respectively herein), and the time that the vehicle is in the flushing area may be counted according to the capturing time of the first captured image and the capturing time of the second captured image.
For example, the difference between the snapshot time of the second snapshot and the snapshot time of the first snapshot may be determined as the length of time that the vehicle has passed through the flushing area.
It should be noted that, considering that the snapshot time of the snapshot is usually the system time of the video monitoring front end, when the natural day is crossed between the above two snapshots, the snapshot time of the second snapshot will be shorter than that of the first snapshot, and when counting the time length of the vehicle passing through the flushing area, the date needs to be considered.
Taking a 24-hour system as an example, when a natural day is crossed between two snapshots, the snapshot time of the second snapshot needs to be increased by 24 hours.
In one example, the detecting that the vehicle enters the flushing area may include:
when the vehicle is detected to run to the position of the first trigger line in the monitoring picture, determining that the vehicle enters a flushing area;
the detecting that the vehicle leaves the flushing area may include:
when it is detected that the vehicle is traveling to the position of the second trigger line in the monitoring screen, it is determined that the vehicle is out of the flushing area.
For example, a position for identifying whether the vehicle enters the flushing area (referred to herein as a first trigger line) may be preset at a designated position at an entrance of the flushing area in the monitoring screen, and a position for identifying whether the vehicle leaves the flushing area (referred to herein as a second trigger line) may be preset at an exit of the flushing area.
When the vehicle is detected to run to the position of the first trigger line in the monitoring picture, determining that the vehicle enters a flushing area; when it is detected that the vehicle is traveling to the position of the second trigger line in the monitoring screen, it is determined that the vehicle is out of the flushing area.
It should be noted that, in the embodiment of the present application, the position where the vehicle travels to the preset trigger line may include that the foremost end of the vehicle reaches the preset trigger line position in the monitoring screen, or that wheels (front wheels or last wheels) of the vehicle reach the preset trigger line position, and the like, and the embodiment of the present application is not limited thereto.
In one example, the determining whether to generate the alert based on the time the vehicle is in the wash zone may include:
when the time that the vehicle is in the flushing area is smaller than a preset time threshold, generating an insufficient flushing time alarm comprising a first snapshot and a second snapshot.
For example, after determining the time that the vehicle is in the flushing area, the time may be compared to a preset time threshold (which may be set according to actual circumstances).
If the duration is less than the preset time threshold, the vehicle is determined to be insufficient in washing time, and at the moment, a warning of insufficient washing time can be generated.
For example, in order to facilitate subsequent forensics, the generated warning may include a snapshot of the vehicle (the number may be one or more, and is set according to the requirement, and the same is applied below).
For example, when it is determined that the vehicle is in the flushing area for less than a preset time threshold, an under-flush time alert including the first snapshot and the second snapshot may be generated.
In one example, for better forensics, another trigger capture position (referred to herein as a third trigger line) may be set at the preset first trigger line and the preset second trigger line positions, and the third trigger line is located between the first trigger line and the second trigger line.
When it is detected that the vehicle is driven to the position of the third trigger line in the monitoring picture, the vehicle is captured, and another captured image (referred to as a third captured image in the text) of the vehicle is obtained.
For example, when it is determined that the vehicle is in the flushing area for less than a time threshold, an under-flush time alert including the first snapshot, the second snapshot, and the third snapshot may be generated.
And step S120, generating an alarm.
In the embodiment of the application, when it is detected that the vehicle does not pass through the flushing area, it is determined that the vehicle is not flushed, and at this time, an alarm, such as an unwashed alarm, may be generated.
For example, to facilitate subsequent forensics, a snapshot of the vehicle may be included in the generated alert.
Referring to fig. 2, a schematic flow chart of another vehicle flushing detection method provided in the embodiment of the present application is shown, and as shown in fig. 2, the vehicle flushing detection method may include the following steps:
step S200, when it is detected that a vehicle of a specified type leaves the worksite, it is detected whether the vehicle passes through a flushing area. If yes, go to step S210; otherwise, go to step S240.
In the embodiment of the application, in order to realize automatic detection of vehicle washing, video monitoring can be carried out on vehicles entering and leaving a construction site.
When it is detected that a vehicle enters the monitored area, it may be determined that the vehicle is entering the worksite or leaving the worksite.
In one example, the detecting that the vehicle leaves the worksite may include:
when the vehicle is detected to enter the monitoring area, detecting the head and the tail of the vehicle;
and if the vehicle head is detected, determining that the vehicle leaves the construction site.
For example, when it is detected that the vehicle enters the monitoring area, the detection of the head and the tail of the vehicle can be performed on the vehicle, that is, whether the vehicle faces the monitoring person in the monitoring picture or the monitoring person in the tail direction is detected.
And if the detection result is that the vehicle head is the vehicle head (namely the vehicle head faces the monitoring personnel in the monitoring picture), determining that the vehicle leaves the construction site.
For example, if the detection result is the vehicle tail (i.e., the vehicle tail faces the monitoring person in the monitoring picture), it is determined that the vehicle enters the construction site.
In one example, when a vehicle is detected entering a worksite, a normal event may be generated to record the vehicle entering the worksite, which may include a snapshot of the vehicle.
It should be noted that, in this example, when the video monitoring front end is erected, it is ensured that the vehicle head faces the video monitoring front end when entering the monitoring screen when the vehicle leaves the building site, but the manner of erecting the video monitoring front end in the embodiment of the present application is not limited thereto, that is, the video monitoring front end may be erected in a manner that the vehicle tail faces the video monitoring front end when entering the monitoring screen when the vehicle leaves the building site, and the specific implementation thereof is not limited herein.
For convenience of description and understanding, the way in which the vehicle head faces the front end of the video surveillance when entering the surveillance screen is taken as an example in the following description when the vehicle leaves the construction site.
In the embodiment of the application, when the vehicle is detected to leave the construction site, the type detection can be carried out on the vehicle so as to determine whether the vehicle is a specified type of vehicle.
For example, the specific type of vehicle may be a vehicle (e.g., a construction vehicle such as a muck truck, a concrete mixer truck, etc.) that needs to be cleaned when leaving the work site, or the like.
In the embodiment of the present application, the type of the vehicle that needs to be subjected to the vehicle flushing detection (i.e., the above-specified type) is not limited to the engineering vehicle such as the slag car and the concrete mixer, but may include other types determined according to actual requirements, and the embodiment of the present application is not limited thereto.
Further, when the type of the vehicle is detected as a non-specified type, a normal event may be generated to record an event that the non-specified type of vehicle leaves the worksite, and the normal event may include a snapshot of the vehicle.
When it is detected that the type of the vehicle is a specified type, it is necessary to further detect whether the vehicle of the specified type passes through the flushing area.
For example, the position of the flushing area may be set in the monitoring screen in advance, and when it is detected that the vehicle enters the monitoring screen, it may be further detected whether the vehicle passes through the flushing area.
In one example, it may be determined whether the vehicle has passed through the wash zone by detecting the lane in which the vehicle left the worksite.
For example, considering that in a practical scenario, multiple lanes may exist at a worksite entrance and exit, and a flushing area may not exist in some of the lanes (i.e., no vehicle flushing device is deployed), when a vehicle of a specified type is detected to leave the worksite, the lane in which the vehicle is located may be detected.
If the lane where the vehicle is located is detected as the lane where the flushing area is located (namely, the vehicle flushing device is deployed in the lane), it is determined that the vehicle passes through the flushing area, and the time that the vehicle is located in the flushing area can be further counted.
And if the detected lane where the vehicle is located is not the lane where the flushing area is located, determining that the vehicle does not pass through the flushing area.
Step S210, determining whether a water out event is received while the vehicle passes through the rinsing area. If yes, go to step S220; otherwise, go to step S230.
In this application embodiment, for avoid the construction side to deal with the vehicle through the regional mode of not washing of washing, when the vehicle process washed the region, can detect vehicle flushing device and go out water.
In one example, a device for detecting whether the vehicle washing apparatus is out of water may be deployed on the vehicle washing apparatus (e.g., a fire service water host), and the device may determine whether the vehicle washing apparatus is out of water by detecting a change in water pressure of the vehicle washing apparatus.
For example, when it is detected that the water pressure reduction condition of the vehicle flushing device meets a preset condition (for example, the water pressure reduction amplitude is greater than a preset threshold), it is determined that the vehicle flushing device is discharging water, and at this time, the device may report a water discharge event, for example, report the water discharge event to the video monitoring front end through a 485 signal; when the fact that the water pressure rising condition of the vehicle flushing device meets a preset condition (for example, the water pressure rising amplitude is larger than a preset threshold value) is detected, it is determined that the vehicle flushing device stops water outlet, at the moment, the device can report a water outlet stopping event, for example, the water outlet stopping event is reported to the video monitoring front end through a 485 signal.
In embodiments of the present application, when a vehicle of a specified type is detected to leave a worksite and the vehicle is detected to pass through a wash zone, it may be determined whether an out-of-water event was received during the vehicle's passage through the wash zone.
Step 220, determining whether to generate an alarm according to the time that the vehicle is in the flushing area, wherein the alarm is used for indicating that the flushing time is insufficient.
In the embodiment of the application, when it is detected that the vehicle passes through the flushing area and the water outlet event is received when the vehicle passes through the flushing area, the time that the vehicle is in the flushing area can be counted, and whether to generate the alarm is determined based on the time that the vehicle is in the flushing area.
In one possible embodiment, the time that the vehicle is in the wash zone is determined by:
when the fact that the vehicle enters the flushing area is detected, capturing the vehicle to obtain a first captured image of the vehicle;
when the vehicle is detected to leave the flushing area, capturing the vehicle to obtain a second captured image of the vehicle;
and counting the time length of the vehicle passing through the flushing area according to the snapshot time of the first snapshot picture and the snapshot time of the second snapshot picture.
For example, the vehicle may be captured when the vehicle is detected to enter the flushing area and the vehicle is detected to leave the flushing area, respectively, to obtain a first captured image of the vehicle, and the time that the vehicle is in the flushing area may be counted according to the capturing time of the first captured image and the capturing time of the second captured image.
For example, the difference between the snapshot time of the second snapshot and the snapshot time of the first snapshot may be determined as the length of time that the vehicle has passed through the flushing area.
It should be noted that, considering that the snapshot time of the snapshot is usually the system time of the video monitoring front end, when the natural day is crossed between the above two snapshots, the snapshot time of the second snapshot will be shorter than that of the first snapshot, and when counting the time length of the vehicle passing through the flushing area, the date needs to be considered.
Taking a 24-hour system as an example, when a natural day is crossed between two snapshots, the snapshot time of the second snapshot needs to be increased by 24 hours.
In one example, the detecting that the vehicle enters the flushing area may include:
when the vehicle is detected to run to the position of the first trigger line in the monitoring picture, determining that the vehicle enters a flushing area;
the detecting that the vehicle leaves the flushing area may include:
when it is detected that the vehicle is traveling to the position of the second trigger line in the monitoring screen, it is determined that the vehicle is out of the flushing area.
For example, a position for identifying whether the vehicle enters the flushing area (referred to herein as a first trigger line) may be preset at a designated position at an entrance of the flushing area in the monitoring screen, and a position for identifying whether the vehicle leaves the flushing area (referred to herein as a second trigger line) may be preset at an exit of the flushing area.
When the vehicle is detected to run to the position of the first trigger line in the monitoring picture, determining that the vehicle enters a flushing area; when it is detected that the vehicle is traveling to the position of the second trigger line in the monitoring screen, it is determined that the vehicle is out of the flushing area.
It should be noted that, in the embodiment of the present application, the position where the vehicle travels to the preset trigger line may include that the foremost end of the vehicle reaches the preset trigger line position in the monitoring screen, or that wheels (front wheels or last wheels) of the vehicle reach the preset trigger line position, and the like, and the embodiment of the present application is not limited thereto.
In one example, the determining whether to generate the alert based on the time the vehicle is in the wash zone may include:
when the time that the vehicle is in the flushing area is smaller than a preset time threshold, generating an insufficient flushing time alarm comprising a first snapshot and a second snapshot.
For example, after determining the time that the vehicle is in the flushing area, the time may be compared to a preset time threshold (which may be set according to actual circumstances).
If the duration is less than the preset time threshold, the vehicle is determined to be insufficient in washing time, and at the moment, a warning of insufficient washing time can be generated.
For example, in order to facilitate subsequent forensics, the generated warning may include a snapshot of the vehicle (the number may be one or more, and is set according to the requirement, and the same is applied below).
For example, when it is determined that the vehicle is in the flushing area for less than a preset time threshold, an under-flush time alert including the first snapshot and the second snapshot may be generated.
In one example, for better forensics, another trigger capture position (referred to herein as a third trigger line) may be set at the preset first trigger line and the preset second trigger line positions, and the third trigger line is located between the first trigger line and the second trigger line.
And when the vehicle is detected to run to the position of the third trigger line in the monitoring picture, capturing the vehicle to obtain a third captured image of the vehicle.
For example, when it is determined that the vehicle is in the flushing area for less than a time threshold, an under-flush time alert including the first snapshot, the second snapshot, and the third snapshot may be generated.
And step S230, generating a device water-out alarm.
In the embodiment of the application, if the water outlet event is not received during the vehicle passing through the washing area, a water outlet failure alarm can be generated for prompting a monitoring person that the vehicle is not washed when passing through the washing area.
For example, the device no water alarm may include a snapshot of the vehicle for subsequent forensics.
And step S240, generating an unwashed alarm.
In the embodiment of the application, when it is detected that the vehicle does not pass through the flushing area, it is determined that the vehicle is not flushed, and at this time, an unwashed warning may be generated.
For example, a snapshot of the vehicle may be included in the no-flush alert to facilitate subsequent forensics.
Referring to fig. 3, a schematic flow chart of another vehicle flushing detection method provided in the embodiment of the present application is shown, and as shown in fig. 3, the vehicle flushing detection method may include the following steps:
step S300, when detecting that the vehicle of the specified type leaves the construction site, detecting whether the vehicle passes through the flushing area. If yes, go to step S310; otherwise, go to step S340.
In the embodiment of the application, in order to realize automatic detection of vehicle washing, video monitoring can be carried out on vehicles entering and leaving a construction site.
When it is detected that a vehicle enters the monitored area, it may be determined that the vehicle is entering the worksite or leaving the worksite.
In one example, the detecting that the vehicle leaves the worksite may include:
when the vehicle is detected to enter the monitoring area, detecting the head and the tail of the vehicle;
and if the vehicle head is detected, determining that the vehicle leaves the construction site.
For example, when it is detected that the vehicle enters the monitoring area, the detection of the head and the tail of the vehicle can be performed on the vehicle, that is, whether the vehicle faces the monitoring person in the monitoring picture or the monitoring person in the tail direction is detected.
And if the detection result is that the vehicle head is the vehicle head (namely the vehicle head faces the monitoring personnel in the monitoring picture), determining that the vehicle leaves the construction site.
For example, if the detection result is the vehicle tail (i.e., the vehicle tail faces the monitoring person in the monitoring picture), it is determined that the vehicle enters the construction site.
In one example, when a vehicle is detected entering a worksite, a normal event may be generated to record the vehicle entering the worksite, which may include a snapshot of the vehicle.
It should be noted that, in this example, when the video monitoring front end is erected, it is ensured that the vehicle head faces the video monitoring front end when entering the monitoring screen when the vehicle leaves the building site, but the manner of erecting the video monitoring front end in the embodiment of the present application is not limited thereto, that is, the video monitoring front end may be erected in a manner that the vehicle tail faces the video monitoring front end when entering the monitoring screen when the vehicle leaves the building site, and the specific implementation thereof is not limited herein.
For convenience of description and understanding, the way in which the vehicle head faces the front end of the video surveillance when entering the surveillance screen is taken as an example in the following description when the vehicle leaves the construction site.
In the embodiment of the application, when the vehicle is detected to leave the construction site, the type detection can be carried out on the vehicle so as to determine whether the vehicle is a specified type of vehicle.
For example, the specific type of vehicle may be a vehicle (e.g., a construction vehicle such as a muck truck, a concrete mixer truck, etc.) that needs to be cleaned when leaving the work site, or the like.
In the embodiment of the present application, the type of the vehicle that needs to be subjected to the vehicle flushing detection (i.e., the above-specified type) is not limited to the engineering vehicle such as the slag car and the concrete mixer, but may include other types determined according to actual requirements, and the embodiment of the present application is not limited thereto.
Further, when the type of the vehicle is detected as a non-specified type, a normal event may be generated to record an event that the non-specified type of vehicle leaves the worksite, and the normal event may include a snapshot of the vehicle.
When it is detected that the type of the vehicle is a specified type, it is necessary to further detect whether the vehicle of the specified type passes through the flushing area.
For example, the position of the flushing area may be set in the monitoring screen in advance, and when it is detected that the vehicle enters the monitoring screen, it may be further detected whether the vehicle passes through the flushing area.
In one example, it may be determined whether the vehicle has passed through the wash zone by detecting the lane in which the vehicle left the worksite.
For example, considering that in a practical scenario, multiple lanes may exist at a worksite entrance and exit, and a flushing area may not exist in some of the lanes (i.e., no vehicle flushing device is deployed), when a vehicle of a specified type is detected to leave the worksite, the lane in which the vehicle is located may be detected.
If the lane where the vehicle is located is detected as the lane where the flushing area is located (namely, the vehicle flushing device is deployed in the lane), it is determined that the vehicle passes through the flushing area, and the time that the vehicle is located in the flushing area can be further counted.
And if the detected lane where the vehicle is located is not the lane where the flushing area is located, determining that the vehicle does not pass through the flushing area.
Step S310, determining whether water mist is detected in the flushing area when the vehicle passes through the flushing area. If yes, go to step S320; otherwise, go to step S330.
In this application embodiment, for avoid the construction side to deal with the vehicle through the regional mode of not washing of washing, when the vehicle process washed the region, can detect vehicle flushing device and go out water.
In one example, whether the vehicle washing device is out of water can be detected in a mode that whether water mist exists in a washing area in a monitoring picture is detected in a video detection mode.
Exemplarily, when the existence of water mist in a flushing area is detected, the water outlet of the vehicle flushing device is determined; when it is detected that the water mist is not present in the flushing area, it is determined that the vehicle flushing apparatus stops discharging water.
In embodiments of the present application, when it is detected that the vehicle leaves the worksite, it may be determined whether water mist is present in the wash zone during the passage of the vehicle through the wash zone.
Step S320, whether an alarm is generated or not is determined according to the time when the vehicle is in the flushing area, and the alarm is used for indicating that the flushing time is insufficient.
In the embodiment of the application, when it is detected that the vehicle passes through the flushing area and the water outlet event is received when the vehicle passes through the flushing area, the time that the vehicle is in the flushing area can be counted, and whether to generate the alarm is determined based on the time that the vehicle is in the flushing area.
In one possible embodiment, the time that the vehicle is in the wash zone is determined by:
when the fact that the vehicle enters the flushing area is detected, capturing the vehicle to obtain a first captured image of the vehicle;
when the vehicle is detected to leave the flushing area, capturing the vehicle to obtain a second captured image of the vehicle;
and counting the time length of the vehicle passing through the flushing area according to the snapshot time of the first snapshot picture and the snapshot time of the second snapshot picture.
For example, the vehicle may be captured when the vehicle is detected to enter the flushing area and the vehicle is detected to leave the flushing area, respectively, to obtain a first captured image of the vehicle, and the time that the vehicle is in the flushing area may be counted according to the capturing time of the first captured image and the capturing time of the second captured image.
For example, the difference between the snapshot time of the second snapshot and the snapshot time of the first snapshot may be determined as the length of time that the vehicle has passed through the flushing area.
It should be noted that, considering that the snapshot time of the snapshot is usually the system time of the video monitoring front end, when the natural day is crossed between the above two snapshots, the snapshot time of the second snapshot will be shorter than that of the first snapshot, and when counting the time length of the vehicle passing through the flushing area, the date needs to be considered.
Taking a 24-hour system as an example, when a natural day is crossed between two snapshots, the snapshot time of the second snapshot needs to be increased by 24 hours.
In one example, the detecting that the vehicle enters the flushing area may include:
when the vehicle is detected to run to the position of the first trigger line in the monitoring picture, determining that the vehicle enters a flushing area;
the detecting that the vehicle leaves the flushing area may include:
when it is detected that the vehicle is traveling to the position of the second trigger line in the monitoring screen, it is determined that the vehicle is out of the flushing area.
For example, a position for identifying whether the vehicle enters the flushing area (referred to herein as a first trigger line) may be preset at a designated position at an entrance of the flushing area in the monitoring screen, and a position for identifying whether the vehicle leaves the flushing area (referred to herein as a second trigger line) may be preset at an exit of the flushing area.
When the vehicle is detected to run to the position of the first trigger line in the monitoring picture, determining that the vehicle enters a flushing area; when it is detected that the vehicle is traveling to the position of the second trigger line in the monitoring screen, it is determined that the vehicle is out of the flushing area.
It should be noted that, in the embodiment of the present application, the position where the vehicle travels to the preset trigger line may include that the foremost end of the vehicle reaches the preset trigger line position in the monitoring screen, or that wheels (front wheels or last wheels) of the vehicle reach the preset trigger line position, and the like, and the embodiment of the present application is not limited thereto.
In one example, the determining whether to generate the alert based on the time the vehicle is in the wash zone may include:
when the time that the vehicle is in the flushing area is smaller than a preset time threshold, generating an insufficient flushing time alarm comprising a first snapshot and a second snapshot.
For example, after determining the time that the vehicle is in the flushing area, the time may be compared to a preset time threshold (which may be set according to actual circumstances).
If the duration is less than the preset time threshold, the vehicle is determined to be insufficient in washing time, and at the moment, a warning of insufficient washing time can be generated.
For example, in order to facilitate subsequent forensics, the generated warning may include a snapshot of the vehicle (the number may be one or more, and is set according to the requirement, and the same is applied below).
For example, when it is determined that the vehicle is in the flushing area for less than a preset time threshold, an under-flush time alert including the first snapshot and the second snapshot may be generated.
In one example, for better forensics, another trigger capture position (referred to herein as a third trigger line) may be set at the preset first trigger line and the preset second trigger line positions, and the third trigger line is located between the first trigger line and the second trigger line.
And when the vehicle is detected to run to the position of the third trigger line in the monitoring picture, capturing the vehicle to obtain a third captured image of the vehicle.
For example, when it is determined that the vehicle is in the flushing area for less than a time threshold, an under-flush time alert including the first snapshot, the second snapshot, and the third snapshot may be generated.
And step S330, generating a device water-out alarm.
In the embodiment of the application, if the water mist is not detected in the flushing area during the vehicle passes through the flushing area, a no-water-outlet alarm can be generated for prompting a monitoring person that the vehicle is not flushed when passing through the flushing area.
For example, the device no water alarm may include a snapshot of the vehicle for subsequent forensics.
And step S340, generating an unwashed alarm.
In the embodiment of the application, when it is detected that the vehicle does not pass through the flushing area, it is determined that the vehicle is not flushed, and at this time, an unwashed warning may be generated.
For example, a snapshot of the vehicle may be included in the no-flush alert to facilitate subsequent forensics.
It should be noted that, in the embodiment of the present application, the above-mentioned processes of vehicle type detection, vehicle head and tail detection, lane detection, detection of whether water mist exists in the flushing area, and the like may be implemented based on deep learning.
For example, taking vehicle type detection as an example, a vehicle type detection network model (deep learning model) may be trained by using training samples (including vehicles and labeled with images of vehicle types) collected in advance, and vehicle type detection may be performed based on the trained deep learning model.
In addition, the vehicle flushing detection method provided by the embodiment of the application can be applied to front-end equipment (such as video monitoring front ends like an IPC (Internet Protocol Camera)) or rear-end equipment (such as an alarm processing platform in an intelligent transportation system) in a video monitoring system; when the vehicle flushing detection method is applied to the front-end device, when the front-end device generates the above-mentioned alarm (such as a flushing time shortage alarm, a non-water-outlet alarm, a non-flushing alarm, etc.), the alarm needs to be uploaded to the alarm processing platform, and the specific implementation thereof is not described herein again.
