Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
First, the concept related to the present application will be explained.
A thermal imaging apparatus: is an apparatus for realizing imaging by non-contact detection of infrared rays. An object in the nature can emit infrared rays, corresponding thermal images and temperature values can be generated according to detected physical infrared radiation energy, the temperature values are calculated, and the thermal imaging equipment is imaging equipment capable of calculating the temperature of the shot object and outputting the temperature values.
An application scenario applicable to the present application is described below.
Fig. 1 is a schematic view of an application scenario provided by an embodiment of the present application, and as shown in fig. 1, the application scenario includes a security door 11 and a baggage security device 12, where a plurality of pedestrians queue to pass through the security door 11 in sequence, and further includes a security inspector 13 on the other side of the security door 11. The pedestrian can place the carried baggage on the conveyor belt of the baggage security check device 12 before entering the security check door 11, and separate detection of the pedestrian and the baggage is performed.
The security check door system in the embodiment of the application can be applied to various occasions, such as subway stations, airports and the like.
When the pedestrian arrives at security door 11, the metal check out test set who installs in security door 11 usually can carry out metal detection to the pedestrian, detects whether the pedestrian has carried the metal on one's body, and luggage safety check out test set 12 detects pedestrian's luggage, for example detects whether carry cutter, unidentified liquid etc. in the luggage. After the baggage passes the detection and the pedestrian passes the detection of the security door 11, the pedestrian can smoothly pass the security door 11. The security personnel 13 arranged on the other side of the security door can further detect the suspicious person. For example, when it is detected that there is an unknown liquid in the luggage, it may be required to further check the unknown liquid, and when it is detected that a pedestrian carries metal on his body, it may be further checked whether a dangerous instrument or the like is carried, so as to secure the pedestrian passing through the security gate 11.
In current security inspection, whether a pedestrian carries dangerous goods or not is mainly detected. With the change of the requirements of various occasions on security inspection, the requirements of security inspection are higher and higher, and the single article detection cannot meet the diversified security inspection requirements.
For example, many people today have a need to measure the temperature of pedestrians to obtain the temperature of the pedestrians, so as to avoid the passage of the pedestrians with high body temperature. In many locations, it is common for security personnel to carry out temperature measurement on pedestrians one by one with a hand-held thermometer. The temperature measurement mode is not only low in efficiency, but also needs security check personnel to be close to the pedestrian to be detected, and is not beneficial to ensuring the safety of the security check personnel.
In view of this, this application embodiment provides a security check door system, can realize carrying out the temperature measurement to the pedestrian automatically, need not security check personnel direct operation, and measurement efficiency is also higher. The scheme of the application will be described with reference to specific examples.
Fig. 2 is a schematic view of a security door system provided in an embodiment of the present application, and as shown in fig. 2, the security door system includes a security door 21, a thermal imaging device 22 and a metal detection device 23 disposed on the security door 21, and an alarm device 24, where:
the thermal imaging device 22 is configured to acquire a first image of a pedestrian located in a first detection area, and acquire a face temperature of the pedestrian according to the first image, where the first detection area is an area through which the pedestrian passes before passing through the security door;
the metal detection device 23 is configured to detect whether the pedestrian carries metal when the pedestrian is located in a second detection area, where the second detection area is an area below the security door;
the alarm device 24 is configured to give an alarm when the face temperature is greater than or equal to a preset temperature and/or it is determined that the pedestrian carries metal.
The thermal imaging device 22 is a device that obtains a thermal image by detecting infrared radiation emitted by a pedestrian and converting the infrared radiation into an electrical signal. The first image is a thermal image captured by the thermal imaging device 22, the first image includes pedestrians, and the temperature of each region of the pedestrians can be obtained according to the first image.
The safety inspection door system in this application embodiment has set up two detection position, is first detection area and second detection area respectively. Fig. 3 is a schematic view of a detection area provided in the embodiment of the present application, and as shown in fig. 3, the first detection area 31 is an area through which a pedestrian 34 passes before passing through the security door, the second detection area 32 is an area below the security door, and both the first detection area 31 and the second detection area 32 are areas through which the pedestrian 34 has to pass through the security door.
The first detection area 31 may be, for example, an area formed in a range of about 0-2 m from the security inspection door, and the thermal imaging detection position in the area is good, so that an imaging picture with a good effect can be captured. When actually detecting a pedestrian, it is not necessary for the pedestrian to stay in the first detection area 31, and it is only necessary for the pedestrian to pass through the first detection area 31. The second detection area 32 is an area in the middle below the security inspection door, and mainly performs metal detection, and in practice, magnetic substance detection, infrared counting and the like can be performed according to different detection devices. The passing area of the security inspection door usually allows only one pedestrian to pass at a time, and when the pedestrian walks to the second detection area 32, metal detection or magnetic substance detection can be conveniently carried out.
The thermal imaging device 22 acquires the first image after the pedestrian passes through the first detection area 31, obtains the face temperature of the pedestrian according to the first image, and compares the face temperature with the preset temperature. If the face temperature of the pedestrian is greater than or equal to the preset temperature, it indicates that the detected pedestrian has overhigh body temperature, and at the moment, the alarm device 24 can give an alarm to remind the security inspector 33 of paying attention.
If the face temperature is lower than the preset temperature, it indicates that the body temperature of the detected pedestrian is normal, and the alarm device 24 may or may not perform any feedback. The pedestrian can now proceed to the second detection zone 32 to be detected by the metal detection device 23. If it is detected that the pedestrian carries a metal object, the alarm device 24 may send an alarm to remind the security inspector 33 to go forward for further inspection. If the pedestrian is detected not to carry metal objects, the pedestrian can normally pass through.
When most of people are normal pedestrians, the detection of the two detection areas can be passed, and the rapid passing of the large stream of people can be realized. The alarm device 24 gives an alarm when an abnormal pedestrian in the stream of people is detected.
The alarm device 24 can be used in various ways, such as a speaker for voice alarm, a warning lamp for light alarm, etc.
The security inspection door system that this application embodiment provided, when the pedestrian carries out security inspection, acquire the first image that is located the pedestrian of first detection zone through thermal imaging equipment to obtain the face temperature of pedestrian according to first image, wherein first detection zone is the pedestrian and passes through the region before passing through the security inspection door. Then, when the pedestrian is located in a second detection area, whether the pedestrian carries metal is detected through metal detection equipment, wherein the second detection area is an area below the security door. When the face temperature is greater than or equal to the preset temperature and/or the pedestrian carries metal, the alarm device gives an alarm. The scheme that this application embodiment provided realizes the temperature measurement to the pedestrian through thermal imaging equipment, and the in-process of going to the people and moving towards the safety inspection door just can realize detecting when first detection area, and measurement of efficiency is high, need not manual operation, avoids the close contact between safety inspection personnel and the pedestrian to also can guarantee safety inspection personnel's security. The safety in the security check door is further ensured by detecting pedestrians in various aspects through the thermal imaging equipment and the metal detection equipment.
In the safety inspection door system, thermal imaging equipment mainly used tests human body temperature, sieves out the pedestrian that the temperature of face surpassed preset temperature. The thermal imaging device can be installed on a security inspection door, detects pedestrians in the first detection area, and processes the first image after the first image is shot. Because the thermal imaging device needs to output the face temperature, the region marking is needed to be carried out in the first image, and the region corresponding to the face of the pedestrian in the first image is obtained, so that only the temperature in the region is identified, and the interference of abnormal temperature in a non-identification range is avoided.
In the embodiment of the application, the thermal imaging device comprises a thermal imaging camera and a processor, the thermal imaging camera is used for acquiring a first image and sending the first image to the processor, and the processor is used for acquiring the face temperature according to the first image. The thermal imaging device images through infrared rays emitted by an object, so that the obtained first image has a certain difference from an image obtained by a common camera. After the thermal imaging camera acquires the first image, the processor processes the first image, and the temperature of each area in the first image can be obtained.
In the above embodiment, after the thermal imaging device acquires the first image, the face temperature of the pedestrian needs to be acquired according to the first image, because the first image acquired by the thermal imaging device may relate to a large area range, and other areas except the pedestrian are backgrounds, which may cause certain interference on the temperature measurement of the pedestrian. Therefore, after the first image is acquired, the corresponding region of the face of the pedestrian in the first image needs to be determined. Two possible ways of determining this are described below with reference to the figures.
Fig. 4 is a first schematic diagram illustrating the determination of the face corresponding area of the pedestrian according to the embodiment of the present application, as shown in fig. 4, a thermal imaging camera 42 is disposed on a security door 41, and the position and the orientation of the thermal imaging camera 42 on the security door 41 are fixed, so that the area photographed by the thermal imaging camera is relatively fixed. Thermal imaging camera 42 can shoot the image of different heights and fat thin pedestrian, then combines the height of security inspection door and most of pedestrian's height, confirms the region of predetermineeing in first image, predetermines the region that the face that the region is the pedestrian corresponds in first image promptly.
For example, in fig. 4, images of several pedestrians of different heights, namely an image 401, an image 402, and an image 403, are captured by the thermal imaging camera 42. The user can mark the position of the face on each image by himself, and a preset area is set by combining the heights of the pedestrians and the heights of most of the pedestrians, and is used as the corresponding area of the face of the pedestrian in the first image. As shown in fig. 4, in an image 43 captured by the thermal imaging camera 42, a preset area 44 is set. After the subsequent thermal imaging camera 42 acquires the first image, the face temperature of the pedestrian is obtained according to the temperature in the preset area 43.
The solution illustrated in fig. 4 is simpler to implement, less costly, but relatively less accurate. Since each person is different in height and weight, it is difficult to consider all the types of pedestrians, for example, for a pedestrian with a particularly high height, the predetermined area 43 defined may not correspond to the face of the pedestrian. Another way of determining this is described below in conjunction with fig. 5.
Fig. 5 is a schematic diagram ii of determining a face corresponding region of a pedestrian according to an embodiment of the present application, and as shown in fig. 5, a thermal imaging camera 52 is disposed on a security door 51, and a face recognition device 53 is further disposed.
When a pedestrian is located in the first detection region, the face recognition device 53 may acquire a second image 54 of the pedestrian and the thermal imaging camera may acquire a first image 55 of the pedestrian. The face recognition device 53 and the thermal imaging camera 52 are both installed on the security door 51 at a short distance, and the shooting area corresponding to the first image 55 is substantially the same as the shooting area corresponding to the second image 54.
The face recognition device 53 can recognize the face of the pedestrian in the second image 54 after obtaining the second image 54, so that the position of the face of the pedestrian on the second image 54 can be known, as shown by the dashed line box in fig. 5. The face recognition device 53 then sends a second image 54 to the processor. After receiving the first image 55 captured by the thermal imaging camera 52 and the second image 54 sent by the face recognition device 53, the processor obtains an area corresponding to the face of the pedestrian in the first image 55 according to the first image 55, the second image 54 and the face of the pedestrian recognized in the second image 54.
There are various methods for obtaining the corresponding region of the face of the pedestrian in the first image 55 through the first image 55 and the second image 54. For example, if the shooting areas corresponding to the first image 55 and the second image 54 are substantially similar and only have a certain translation, the area corresponding to the face in the first image 55 can be obtained by performing the corresponding translation based on the area of the face recognized in the second image 54. For example, the first image 55 and the second image 54 may be subjected to image fusion, so as to obtain a corresponding region of the face in the first image 55 according to the region of the face recognized in the second image 54.
It is understood that the first image actually captured by the thermal imaging camera is different from the ordinary image in display, and fig. 4 and 5 are only schematic diagrams for illustrating the solution of the present application and do not show the image actually captured.
In the example of fig. 5, the security door system includes a thermal imaging device and a face recognition device, and typically, the thermal imaging device includes a thermal imaging camera and a processor, and the thermal imaging camera takes a first image and then is processed by the processor in the thermal imaging device to obtain the temperature of each area on the first image. The face recognition device can also comprise a camera and a processor, the camera shoots a second image, and then the processor in the face recognition device carries out face recognition processing on the second image.
Fig. 6 is a schematic view of the installation of the apparatus provided in the embodiment of the present application, and as shown in fig. 6, only the thermal imaging apparatus 63 may be installed on the security door 61 on the left side. On the right, a thermal imaging device and a face recognition device may be mounted on the security door 62.
In some embodiments, the thermal imaging device and the face recognition device may be two separate devices, each device including a camera and a processor.
In some embodiments, the thermal imaging device and the face recognition device may be two parts of one device. For example, on the right side of fig. 6, the device 64 includes two cameras, i.e., a thermal imaging camera and a normal camera, which respectively collect images, and then the two cameras are processed by the processor to obtain the face temperature.
After determining the corresponding region of the face of the pedestrian in the first image 55, the processor may then derive the face temperature. Generally, the highest temperature of the face of the pedestrian in the corresponding region in the first image 55 is taken as the face temperature, and may be displayed on the first image 55.
Fig. 7 is a schematic view of the face temperature provided in the embodiment of the present application, as shown in fig. 7, in the first image 71, a region 72 corresponding to the face of the pedestrian in the first image 71, and if the maximum temperature in the region 72 is 32.4 degrees, the temperature of the pedestrian can be obtained to be 32.4 degrees.
Optionally, the security door system may further include a display, and the display is connected to the thermal imaging device and is used for displaying the face temperature of the pedestrian. Fig. 8 is a schematic diagram of a display provided in the embodiment of the present application, and as shown in fig. 8, a display 81 is disposed on a security door 82. When the thermal imaging device detects the face temperature of the pedestrian, the obtained face temperature can be sent to the display 81 for display. As shown in fig. 8, when the obtained face temperature is 37.2 degrees, "37.2 degrees" is displayed on the display 81.
The display 81 illustrated in fig. 8 is mounted on the security door 82, and alternatively, the display 81 may not be mounted on the security door 82. Alternatively, when the temperature is lower than the preset temperature, the display 81 may be set to display a normal color, such as green, and when the temperature is higher than or equal to the preset temperature, the display 81 may be set to display an abnormal color, such as red, and the like.
And when the temperature of the pedestrian is lower than the preset temperature, the pedestrian walks to the second detection area for detection. At this moment, the metal detection equipment can detect the pedestrian and judge whether the pedestrian carries metal. For example, metal and magnetic detection coils may be provided, with multiple detection coils detecting pedestrians. When a certain area of the pedestrian is found to have metal, optical and sound alarm is correspondingly carried out, abnormity is prompted, and the general position of the metal is informed to security personnel. Optionally, the system also comprises an infrared correlation device for detecting the number of pedestrians passing through and counting the number of pedestrians passing through the security inspection door. Optionally, other devices such as a radar or a probe may be included to perform corresponding detection.
Furthermore, the alarm device can be set differently according to different alarm modes. For example, the alarm device may include a speaker to sound an alarm when the temperature of the face is greater than or equal to a preset temperature and/or when the pedestrian carries metal.
For example, the alarm device may include an alarm lamp that gives a light alarm when the temperature of the face of the person is greater than or equal to a preset temperature, and/or when the pedestrian carries metal.
Optionally, the security inspection door system can also be provided with an electronic fence, and the fence has two states, namely a passing state and an intercepting state. When the temperature of the face of the person is larger than or equal to the preset temperature and/or the pedestrian carries metal, the fence is switched to an intercepting state to prohibit the pedestrian from passing through the security inspection door, so that the security inspection personnel can conveniently go forward for further inspection.
Optionally, the security check door system still includes luggage safety inspection equipment, and luggage safety inspection equipment can carry out the safety check to pedestrian's luggage, ensures the security of the luggage that passes through.
The following describes the embodiment of the present application with reference to fig. 9.
Fig. 9 is a schematic view of a detection flow of a security inspection door provided in an embodiment of the present application, as shown in fig. 9, including:
and S901, separating the person from the bag, and detecting the luggage in a luggage security check device.
The security door system is respectively provided with detection equipment for pedestrians and luggage, and the detection equipment is used for separately detecting the pedestrians and the luggage.
And S902, when the pedestrian reaches the first detection area, the thermal imaging device detects the pedestrian for the first time.
The first detection is to detect the temperature of the pedestrian to obtain the face temperature of the pedestrian.

And S903, detecting whether the detection is normal for the first time, if so, executing S906, and if not, executing S904.
And S904, the alarm device gives an alarm.
And S905, indicating that the body temperature detection result of the pedestrian is abnormal through the alarm signal of the alarm device.
When the face temperature of the pedestrian is greater than or equal to the preset temperature, the body temperature of the pedestrian is high, and further checking and confirmation are needed. At the moment, the alarm device sends out an alarm signal to indicate that the body temperature detection result of the pedestrian is abnormal. Taking the alarm signal as the voice alarm signal as an example, after the security check personnel hear the voice alarm signal sent by the alarm device, the security check personnel can know that the detection result of the body temperature of the pedestrian is abnormal according to the indication of the voice alarm signal, and perform corresponding processing in time, for example, temporarily forbidding the pedestrian to pass through the security check door system, further detecting the body temperature of the pedestrian, and the like. When the face temperature of the pedestrian is lower than the preset temperature, the body temperature of the pedestrian is normal, and the next detection can be carried out.
S906, the pedestrian continues to pass to the second detection area, and the metal detection device detects the pedestrian for the second time.
The second detection area is another detection position, is usually located below the security inspection door, and is used for detecting whether the pedestrian carries objects such as metal.
