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. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
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 dangerous goods positioning method provided by an embodiment of the present application is shown, wherein the dangerous goods positioning method may be applied to a device with a dangerous goods positioning function in a video monitoring system (referred to herein as a dangerous goods positioning device), and may include, but is not limited to, a video monitoring front-end device (such as IPC (Internet Protocol Camera, webcam)) or a video monitoring back-end device (such as NVR (Network Video Recorder, network hard disk recorder)), and the like, and as shown in fig. 1, the dangerous goods positioning method may include the following steps:
step S100, a monitoring picture of the monitoring area is obtained, and dangerous goods in the monitoring picture are identified.
In the embodiment of the application, the dangerous goods positioning device can acquire a monitoring picture of a monitoring area through a video monitoring front-end device (hereinafter, IPC is taken as an example) and identify goods appearing in the monitoring picture so as to determine whether dangerous goods exist or not.
For example, the hazardous materials location device may model the items that appear in the monitoring screen and match a pre-stored model of the hazardous materials to determine whether the hazardous materials appear in the monitoring screen.
For another example, a database of dangerous goods may be built, and the dangerous goods determined by image segmentation and similarity comparison.
For another example, a neural network is trained from existing images of the dangerous goods, and then the trained neural network is used to identify the dangerous goods.
And step S120, when the dangerous goods are identified, positioning the dangerous goods and a first target object related to the dangerous goods, and sending the position information of the dangerous goods and the position information of the first target object to the appointed terminal.
In the embodiment of the application, when the dangerous goods positioning device identifies that a dangerous goods exists in the monitoring picture, the dangerous goods positioning device can associate the dangerous goods with the objects appearing in the monitoring picture to determine the associated objects (referred to as first target objects and also referred to as holders of the dangerous goods in the text).
The first target object associated with the dangerous object is an object carrying the dangerous object.
In the embodiment of the application, after the first target object associated with the dangerous object is determined by the dangerous object positioning device, the dangerous object and the first target object can be positioned, and the position information of the dangerous object and the position information of the first target object are sent to the designated terminal, such as the alarm processing terminal, and further, the alarm processing personnel (such as security guards, patrol officers, darts and the like) can track the dangerous object and the first target object according to the position information of the dangerous object and the position information of the first target object received by the alarm processing terminal, so that possible dangerous behaviors can be prevented in time.
In one example, the location information of the dangerous goods may be determined based on the location information of the monitoring front-end device monitoring the dangerous goods and the information such as the angle of view at which the dangerous goods are located, or the corresponding scene location may be determined according to the matching of the background images, thereby determining the location information of the dangerous goods.
It can be seen that in the process of the method shown in fig. 1, by identifying the dangerous goods in the monitoring screen of the monitoring area, when the dangerous goods are found, the dangerous goods and the first target object associated with the dangerous goods are positioned, and the dangerous goods and the position information of the first target object are sent to the designated terminal, and the alarm processing personnel performs corresponding processing according to the position information of the dangerous goods and the position information of the first target object, so that the coverage range of dangerous goods finding is expanded, and the efficiency and accuracy of dangerous goods finding are improved.
Further, in the embodiment of the invention, in order to enable the alarm processing personnel to more accurately find the holder of the dangerous goods, when the dangerous goods positioning device sends the position information of the dangerous goods and the position information of the first target object to the alarm processing terminal, the information of the first target object such as the image information and the identity information of the first target object can also be sent to the alarm processing terminal, so that the alarm processing personnel can more accurately find the first target object according to the image information and the identity information of the first target object.
Accordingly, in one embodiment of the present invention, when a dangerous object is identified, the dangerous object positioning method may further include:
Acquiring image information and identity information of a first target object;
And sending the image information and the identity information of the first target object to the alarm processing terminal.
In this embodiment, when the dangerous goods positioning device identifies that a dangerous goods exists in the monitoring screen and determines the first target object, the dangerous goods positioning device may query information of the first target object in the data center according to the face snapshot image of the first target object.
The information of the first target object may include, but is not limited to, identification information (such as identification card information) of the first target object, image information (such as credentials), and the like.
In this embodiment, after the dangerous goods positioning device queries the image information and the identity information of the first target object, the obtained image information and the identity information of the first target object may be sent to the alarm processing terminal, so that after the alarm processing personnel finds the first target object according to the position information of the first target object, the identity of the first target object may be verified according to the image information and the identity information of the first target object.
Further, in the embodiment of the invention, most dangerous behaviors are considered to belong to impulsive behaviors, and if the alarm prompt can be timely made, the dangerous behaviors can be prevented to a certain extent.
Accordingly, in one embodiment of the present invention, when a dangerous object is identified, the dangerous object positioning method may further include:
acquiring communication identification information of a first target object;
And carrying out alarm reminding on the first target object according to the communication identification information of the first target object.
In this embodiment, communication identification information, such as a phone number, may also be stored in the data center, and after the dangerous goods positioning device determines the first target object, the data center may search for matching communication identification information according to the face image of the first target object, and alert the first target object according to the communication identification information of the first target object, for example, alert the first target object with a phone call or/and a short message.
Further, in embodiments of the present application, it is contemplated that there may be a large difference in the dangers of different types of dangerous objects, e.g., sticks with relatively less dangers than firearm explosives and with relatively greater dangers; similarly, there may be a large difference in the dangers of different types of objects carrying dangerous objects, e.g., objects that have been subject to dangerous activity are relatively more dangerous than objects that have not.
Accordingly, in one embodiment of the present invention, when a dangerous object is identified, the dangerous object positioning method may further include:
determining a risk coefficient and/or risk information of a first target object;
And sending the danger coefficient and/or the danger information of the first target object to the alarm processing terminal.
In this embodiment, after the dangerous goods positioning device identifies the dangerous goods in the monitoring screen and determines the first target object, the risk coefficient and/or the risk information of the first target object may be determined.
For example, the risk coefficients of different types of dangerous objects or/and the risk coefficients of different types of objects may be preconfigured, after the dangerous object positioning device identifies the dangerous object in the monitoring screen and determines the first target object, the type of the dangerous object or/and the type of the first target object (if there is a dangerous behavior record or no dangerous behavior record) may be determined, and according to the type of the dangerous object or/and the type of the first target object, the preconfigured risk coefficients of different types of dangerous objects or/and the risk coefficients of different types of objects may be queried to determine the risk coefficient of the first target object.
The dangerous coefficient of the dangerous goods can be determined according to the use information or/and the functional information of the dangerous goods.
For example, for firearm type dangerous goods (e.g., handgun, submachine gun, etc.), the risk factor can be determined based on the penetration force, magazine capacity (used to determine the bullet change frequency), etc.
The hazard information may include, but is not limited to, one or more of the hazard range of the hazard (e.g., length of hazard, furthest hazard distance), the solution of the hazard, which locations around are convenient to conceal, etc. For example, for firearms and the like, a ballistic vest is worn, a hand-held shield type; indicating a gas mask model for smoke and the like; for flash bullets and the like, indicating the type of the mirror; for fireballs and the like, fireproof materials (e.g., foam extinguishing agents and the like), fireproof clothing, fireproof boots and the like are indicated. For example, the risk coefficient W0 of the object associated with the dangerous object may be determined by the following formula:
W0＝aW1+bW2
wherein a and b are weighting coefficients, W1 is a dangerous coefficient of dangerous goods, and W2 is a dangerous coefficient of objects.
In this embodiment, after the dangerous goods positioning device determines the dangerous coefficient of the first target object, the dangerous coefficient of the first target object may be sent to the alarm processing terminal, so that the alarm processing personnel may take corresponding measures according to the dangerous coefficient of the first target object.
For example, when the risk coefficient of the first target object is small, the alarm processing personnel can search for the dangerous object and the first target object only according to the position information of the dangerous object and the position information of the first target object; when the danger coefficient of the first target object is larger, the alarm processing personnel can evacuate other personnel in the corresponding place, and find out the dangerous goods and the first target object according to the position information of the dangerous goods and the position information of the first target object.
Further, in the embodiment of the present application, after the first target object carries the dangerous object into the monitoring area, the carried dangerous object may be abandoned, and the dangerous object may be acquired by another object and associated with another object, so that, in order to better achieve positioning of the dangerous object, when the dangerous object is associated with another object, the dangerous object positioning device may acquire and record information of the other object, such as image information, identity information, communication identification information, and the like.
Accordingly, in one embodiment of the present application, the method for positioning dangerous goods may further include:
when the dangerous goods are detected to be separated from the first target object and then are associated with the second target object, the image information, the identity information and the communication identification information of the second target object are recorded.
In this embodiment, after the dangerous goods positioning device detects that the dangerous goods are separated from the first target object, the dangerous goods in the monitoring screen may be locked, and it may be determined whether the dangerous goods are associated with other objects, i.e. are picked up by the other objects.
When the dangerous object is separated from the first target object, if the distance between the dangerous object and other objects is smaller than the preset distance and the motion information is matched with the motion information of the other objects, it can be determined that the dangerous object is picked up by the other objects.
When the dangerous goods positioning device detects that the dangerous goods are associated with other objects (referred to as second target objects herein and also referred to as pickups of the dangerous goods), the dangerous goods positioning device can record image information, identity information and communication identification information of the second target objects, so that when the dangerous goods are not in a monitoring picture, an alarm processing personnel can better position the dangerous goods according to the recorded information of the second target objects.
In order to enable those skilled in the art to better understand the technical solutions provided by the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described below with reference to specific examples.
Referring to fig. 2, an 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 IPC, NVR, a data center, a personnel library for recording, and an alarm processing terminal. The IPC is used for acquiring a monitoring picture of the monitoring area, and the NVR is used for identifying and positioning dangerous goods in the monitoring picture (i.e., taking a dangerous goods positioning device as an NVR for example).
As shown in fig. 3, based on the application scenario shown in fig. 2, the implementation flow of the dangerous goods positioning scheme provided by the embodiment of the application is as follows:
The NVR can acquire a monitoring picture of the monitoring area through the IPC and identify the articles appearing in the picture to determine whether dangerous articles exist.
When the NVR identifies that dangerous goods exist in the monitoring picture, the NVR can further identify the holder of the dangerous goods and acquire the face snapshot picture of the holder of the dangerous goods through the IPC.
The NVR may take a snapshot of the face of the holder of the dangerous goods, query the data center for matching information to obtain information of the holder of the dangerous goods, which may include, but is not limited to, name, identification card information, phone number, credentials, etc., and save the queried information of the holder of the dangerous goods to a local database.
The parameter structure of the information of the holder of the dangerous goods can comprise a number, a name, identity card information, a telephone number, credentials and the like.
In this embodiment, after the NVR queries the information of the holder of the dangerous goods, on one hand, an alert (including a phone call or/and a sms) may be sent to the terminal of the holder of the dangerous physical according to the phone number of the holder of the dangerous goods.
On the other hand, the NVR may also query record information (such as whether there is dangerous behavior, the number of times of dangerous behavior, etc.) of the holder of the dangerous object in the record personnel library according to the holder information of the dangerous object, such as the identity card information, calculate the risk coefficient of the holder of the dangerous object according to the queried record information of the holder of the dangerous object and the type of the dangerous object, and send the risk coefficient of the holder of the dangerous object, the position of the dangerous object and the position of the holder of the dangerous object to the alarm processing terminal, such as the terminal device of the searcher within the preset distance of the monitoring area center.
In this embodiment, when the NVR detects that the holder of the dangerous object discards the dangerous object, the NVR can lock the dangerous object (perform fixed-point monitoring on the position where the dangerous object finally appears) and detect whether the dangerous object is picked up.
If the NVR detects that the dangerous goods are picked up, the NVR can acquire the face picture of the pick-up person of the dangerous goods through the IPC, and searches matched information in the data center according to the face picture of the pick-up person of the dangerous goods so as to obtain information of the pick-up person of the dangerous goods, wherein the information can comprise but is not limited to names, identity card information, telephone numbers, credentials and the like, and the information of the pick-up person of the inquired dangerous goods is stored in a local database.
The parameter structure of the information of the pick-up person of the dangerous goods can comprise a number, a name, identity card information, a telephone number, credentials and the like.
It should be noted that, when the NVR detects that the dangerous object is picked up, the NVR may also locate the pickup of the dangerous object, and send the position information of the pickup of the dangerous object to the alarm processing terminal.
In this embodiment, after the alarm processing personnel (e.g., seekers) obtain the location information of the dangerous goods and the holders of the dangerous goods, the dangerous goods and the holders of the dangerous goods can be found according to the location information of the dangerous goods and the holders of the dangerous goods.
When the seeker finds the holder of the dangerous goods, the identity of the holder of the dangerous goods can be verified in a face recognition mode.
If the dangerous goods are discarded by the holder of the dangerous goods and picked up, the searcher can determine whether the dangerous goods and the pickers of the dangerous goods are in the monitoring area or not, if so, the dangerous goods and the pickers of the dangerous goods are searched according to the position information of the dangerous goods and the position information of the pickers of the dangerous goods.
If the dangerous goods are not in the monitoring area, the searcher can inquire the information of the pickers of the dangerous goods and contact the pickers of the dangerous goods according to the inquired information of the pickers of the dangerous goods so as to realize the positioning of the dangerous goods.
When the searcher finds the dangerous goods, the dangerous goods can be verified (whether the found dangerous goods are consistent with the dangerous goods identified in the monitoring picture or not is verified), and the checking result is saved to the data center.
It should be noted that, in the embodiment of the present invention, when the separation of the holder of the dangerous object from the dangerous object is not detected and the dangerous object is not located in the monitoring area, the searcher may query information of the holder of the dangerous object, and contact the picker of the dangerous object according to the queried information of the picker of the dangerous object, so as to achieve positioning of the dangerous object.
In addition, in this embodiment, the NVR may also store information of the hazardous materials to a local database after the hazardous materials are identified.
The parameter structure of the information of the dangerous goods can comprise: dangerous goods number, holder number, dangerous goods name, dangerous goods appearance time (identification of dangerous goods is identified), dangerous goods grabbing and photographing, holder grabbing and photographing, pick-up number, pick-up grabbing and photographing, pick-up time and the like.
In the embodiment of the application, the dangerous goods in the monitoring picture are identified by acquiring the monitoring picture of the monitoring area; when dangerous goods are identified, the dangerous goods and a first target object associated with the dangerous goods are positioned, and the position information of the dangerous goods and the position information of the first target object are sent to a designated terminal, so that the coverage range of dangerous goods discovery is expanded, and the efficiency and accuracy of dangerous goods discovery are improved.
