The gate control device of the embodiment of the invention corresponds to the gate control method, and the technical characteristics and the beneficial effects described in the embodiment of the gate control method are all applicable to the embodiment of the gate control device.
It will be understood by those skilled in the art that all or part of the processes for implementing the gate control method according to the above embodiments may be implemented by using a computer program to instruct related hardware, and the program may be stored in a non-volatile computer-readable storage medium, for example, in an embodiment, the program may be stored in a storage medium of a computer system and executed by at least one processor in the computer system, so as to implement the processes including the above gate control method according to the embodiments. The storage medium may be a magnetic disk, an optical disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), or the like.
In one embodiment, the gate control method can be applied to a gate control system scene.
In the conventional technology, a controller opens a gate if a white list of people is identified in a video monitoring picture of the gate. The following two situations are easy to occur at this time:
1. the door opening time is not right, when the white list personnel are far away from the gate, if the intelligent identification module identifies the information of the personnel, the gate can be opened by the controller. This may cause the following: 1.1 before the white list personnel go to the gate, the gate is still opened and is easily mixed into a defense area by other people; 1.2 white list personnel just walk before the floodgate machine, the controller has closed the floodgate machine because the duration of opening the floodgate has arrived, only can make the floodgate machine open the door after needing recognization again, reduces current efficiency.
2. The multiple gates simultaneously open the door for the same person, the gates installed side by side are continuously arranged, white list persons can simultaneously appear in corresponding video monitoring pictures of the multiple gates, the gates to which the video monitoring pictures belong can be opened, and the persons only pass through one gate, so that other gates can be kept in an opened state all the time until the time is closed by the controller, and the gates are not in a defense state during the time and are easily mixed into a defense area by other persons.
In the scheme, the control module not only acquires the identification information of the human face targets, but also needs to acquire the coordinate conditions of the targets in the picture in real time, and after comprehensive judgment, determines whether to open the door or not and when to open the door.
Specifically, as shown in fig. 4, the scheme relates to a video acquisition module, an intelligent identification module, a control module, a gate module and the like; face information of the white list personnel is input into a system database in advance.
1. The video acquisition module acquires monitoring videos in real time and sends the monitoring videos to the intelligent identification module, the video acquisition module can be arranged in the camera device, and the camera device is installed at the gate.
2. When the intelligent identification module identifies that the personnel in the video monitoring image is the white list personnel, the related information of the personnel is sent to the control module (event pushing).
3. The video monitoring images are continuous in the video code stream, and the intelligent identification module continuously sends the positions of the personnel in the video monitoring images in the step 2 to the control module.
4. And (3) when the control module receives the white list personnel information in the step (2), the control module does not directly send a switching-off command, but continuously receives the coordinate information of the personnel, integrates the current position + position moving method of the personnel and judges the timing of switching-off the door.
5. The control module judges that the door opening time is mature and sends a door opening command to the gate module.
The intelligent identification module and the control module can be arranged in an access control system, and the gate module is arranged on a gate and used for controlling the gate to open and close the gate.
In step 2, when the intelligent identification module identifies the person in the video monitoring image, a unique mark symbol (object ID) is used for representing the person, and the unique mark symbol and other information of the person are sent to the controller. The object ID can be a certain unique attribute field of the personnel in the database, such as a work number, a school number and a certificate number; or may be generated by the smart identification module itself, such as an accumulated number.
In step 3, the intelligent identification module sends the object ID and the position of the person corresponding to the object ID in the video monitoring image to the control module in real time. The sending mode can be selected from the following modes:
the first method is as follows: firstly, coordinate information is carried in the event pushing in the step 2, then as long as the intelligent identification module continuously pushes the events, the control module can know that the events are the same target person through the object ID, and the position condition of the target person can be obtained in real time by taking the coordinates in the events.
The second method comprises the following steps: the object ID and the coordinate information are directly superposed into the video code stream and are sent to the control module from the intelligent identification module, so that the coordinate information is ensured to be as timely as the picture.
The third method comprises the following steps: a special link (such as Socket connection, interface callback and the like) is arranged between the intelligent identification module and the control module and is used for sending object ID and coordinate information in real time.
In step 4, the actual position of the target person is calculated according to the coordinates of the target person in the video monitoring image, which is specifically as follows:
the camera view field width F of the plane where the face is located can be obtained from the width of the face in the video monitoring image, and the formula is as follows:
F＝Pw/Fw×Fr (1)
pw is the width of the video monitoring image; fw is the width of the face in the video monitoring image, and the width can be directly obtained from face coordinates; fr is the real width of the face of the person, and the value can be recorded when a white list is added, or an average value can be uniformly used.
As shown in fig. 5, at a distance D from the camera directly in front of the camera, the camera view width is F, and the relationship between F and D is as follows:
D＝F×fs (2)
where fs is a fixed coefficient related to the camera focal length and the size of the light-sensing element.
Meanwhile, as shown in fig. 6, the distance from the center of the face to the vertical plane where the center line of the camera is located is represented by Dx, and the formula for calculating Dx is as follows:
Dx＝Fx/Pw×F (3)
fx is the X-axis distance from the coordinates of the center of the human face in the video monitoring image to the center of the video monitoring image; pw is the width of the video monitoring image; f is the camera field of view width at this point.
Thus, the control module can obtain two coordinates D, Dx of the face in fig. 6 every time the face coordinates are received, so that two door opening conditions can be set for the two coordinates
D<Dmax (4)
Dxmin<Dx<Dxmax (5)
In the above formula, Dmax, Dxmin, and Dxmax are constants, and an appropriate value can be obtained through actual testing. When the two conditions are both in accordance, the control module issues a door opening command.
Furthermore, the coordinates of the target person at the next time may be predicted according to the existing continuous coordinates of the human face target, for example, the current time is T2, and the previous time is T1. T2D, T2Dx, T1D, T1Dx are the D, Dx coordinates at times T2 and T1, respectively, then we can predict the two corresponding coordinates T3D, T3Dx at the next time T3
T3D＝(T2D-T1D)×(T3-T2)/(T2-T1)+T2D (6)
T3Dx＝(T2Dx-T1Dx)×(T3-T2)/(T2-T1)+T2Dx (7)
Can continue to overlap T3D, T3Dx respectively in equation (4), (5), can confirm opening the door a moment in advance like this, make personnel keep original walking speed when crossing entrance guard, need not stop before the entrance guard intentionally, improve the smoothness nature of the process of opening the door.
In summary, in the scheme, after the intelligent identification module identifies that the person in the video monitoring image is a white list person, the intelligent identification module continuously sends real-time coordinate information of the white list person in the video monitoring image to the control module, and the control module calculates position information between the person and the gate to judge a proper gate opening time;
the intelligent identification module analyzes the face in the video monitoring image in real time, marks (object ID) on the person after identifying the person in the event white list, sends the mark and the person information to the control module, then continuously tracks the person, and sends the change of the position of the person to the control module in the form of mark and coordinate;
the control module receives the coordinates of the face target in the video monitoring image, and calculates the position of the target person from the gate according to the width of the face in the video monitoring image and the coordinate information of the central point in the video monitoring image;
the control module receives the white list target, does not directly open the door, but continuously analyzes the position condition between the target and the gate machine, and opens the gate at a proper time.
The scheme can be utilized to realize that: 1. when the white list personnel are far away from the gate, the controller does not open the gate even if the face module identifies the information of the personnel. When the personnel enter/are about to enter the preset area, the gate machine is opened, thus preventing the gate from being opened prematurely
2. 3 constants in formulas (4) and (5) are set reasonably, so that the condition that multiple gates open the door for the same person at the same time can be avoided, and the situation that the gate is opened at all times and is mixed into a defense area by other people is prevented.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
