Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a body temperature detecting method according to an exemplary embodiment of the present disclosure, which is applied to a body temperature detecting device, for example, an intelligent attendance checking device, an intelligent access control device, or other devices with an image capturing function. The body temperature detection device comprises an image acquisition module and a temperature measurement module, wherein the image acquisition module and the temperature measurement module are arranged adjacently. In the embodiment of the present disclosure, the temperature measurement module may be a non-contact body temperature detection device, which detects the body temperature of the user through thermal radiation, for example, an infrared body temperature detection device.
For convenience of description, in the following description of the present disclosure, a temperature measurement module is described as an infrared body temperature detection device, and when the infrared body temperature detection device performs body temperature detection, the forehead temperature of the face of the user may be selected for detection. In order to make the body temperature detection result accurate, it is necessary to ensure that the distance between the forehead part of the person to be measured and the infrared body temperature detection device cannot exceed the distance required by the infrared body temperature detection device.
As shown in fig. 1, the body temperature detection method includes the following steps.
In step S101, a distance between the user and the body temperature detection device is determined based on depth information of a face image of the user with an image capturing module.
The image acquisition module may be a video camera, a still camera, or the like for acquiring images of the user. When the image acquisition module acquires a facial image of a user, the distance between each point in the facial image and a camera plane in the visual field of the image acquisition module, namely depth information, needs to be acquired so as to reflect the geometric shape of the facial surface.
The depth information of the face image can be obtained by a geometric method through parameters of the image acquisition module, the distance between the lens and the image and the like.
In an embodiment of the present disclosure, the depth information of the face image may be calculated based on a geometric distance measurement principle by using key feature points of the face that is performing face image acquisition. The depth information of the face image is used as the distance between the face image and the body temperature detection device when the body temperature is detected.
In the embodiment of the disclosure, when the distance between the user and the body temperature detection device is determined by using the depth information of the facial image of the user determined by the image acquisition module, and when the distance between the lens of the image acquisition module of the body temperature detection device and the set temperature measurement module is not greater than the preset threshold value, the obtained depth information of the facial image of the user can be used as the distance between the body temperature person to be measured and the body temperature detection device.
When the distance between the lens of the body temperature detection device and the temperature measurement module arranged on the lens is large, the obtained depth information of the facial image of the user can be corrected through the difference value of the distances between the lens and the temperature measurement module, and whether the position of the user at the moment can obtain an accurate body temperature detection result or not is accurately judged through the depth information of the facial image.
In an embodiment, the human face image may be identified to be present in the image based on the image acquired by the image acquisition module. When the face image of the human body exists in the image, people are found to enter a detection area of the body temperature detection device, and the distance between the face image of the user and the body temperature detection device is determined by the image acquisition module.
In step S102, when the distance does not exceed the preset body temperature detection distance threshold, the temperature measurement module is controlled to obtain body temperature data of the user.
The body temperature detection distance threshold value can be preset according to performance parameters of infrared body temperature detection equipment configured by the body temperature detection device, and when the distance between a body temperature person to be detected and the temperature measurement module does not exceed the preset body temperature detection distance threshold value, a more accurate body temperature detection result can be obtained.
The temperature measurement module can comprise two or more infrared body temperature detection devices to reduce measurement errors of body temperature detection and enable the obtained body temperature data of the human body to be more accurate.
When the body temperature data of the user is obtained, the body temperature data can be determined based on multiple detections. The body temperature detection of the user can be performed for multiple times in a unified manner within a preset time, and when the difference between the body temperature data detected for multiple times is not large, the average value of the body temperature data detected for multiple times can be taken as the body temperature data of the user. When there is some abnormal body temperature data in the body temperature data detected for multiple times, for example, the difference between the abnormal body temperature data and other body temperature data is large, the abnormal body temperature data may be discarded, and the average value of the body temperature data detected for multiple times is taken as the body temperature data of the user.
According to the embodiment of the disclosure, the distance between the facial image of the user and the body temperature detection device is determined by the image acquisition module, and when the distance does not exceed the preset body temperature detection distance threshold value, the temperature measurement module is controlled to acquire body temperature data of the user, so that the body temperature of the user can be accurately, quickly and conveniently detected, the propagation hidden danger of infectious diseases is reduced, and the public health and safety are ensured.
In one embodiment, the image acquisition module is a binocular camera.
Fig. 2 a-2 b are schematic diagrams illustrating distance determination using a binocular camera according to an exemplary embodiment of the present disclosure, the binocular camera obtains two synchronous exposure images of a face image through calibrated two cameras by using a bionics principle, and performs distance measurement on a human face in the image through calculation of parallax of the two images.
Referring to fig. 2a and 2B, when capturing a face image of a user, the binocular cameras, namely, the cameras a and B shown in the figure, perform shooting simultaneously by using the cameras a and B, and a distance z between the face image of the user and a plane where the binocular cameras are located, that is, depth information of the face image, may be determined by a focal length f of the binocular cameras, a distance B between the cameras a and B, and a parallax d.
The focal length f and the distance b can be obtained through parameters of a binocular camera or through experiments in advance. The intersection points of connecting lines between the user and the cameras A and B and the X axis are xl and xr, and the coordinate difference between coordinate points of xl and xr is the parallax d. By geometric algorithms, z ═ f × b/d can be obtained.
In fig. 2a, the infrared temperature measurement device is close to the setting position of the binocular camera, and when the infrared temperature measurement device is not greater than the preset distance threshold, the acquired depth information of the facial image of the user, namely the distance z, can be used as the distance between the body temperature person to be measured and the body temperature detection device.
In fig. 2b, the infrared temperature measuring device and the binocular camera are arranged at a far distance, that is, the distance between the user and the infrared temperature measuring device is greatly different from the distance between the face image of the user and the binocular camera, and the depth information can be corrected by the difference between the distances between the binocular camera and the infrared temperature measuring device, so as to obtain the distance between the user and the infrared body temperature detecting device. As shown in FIG. 2b, the distance between the corrected user and the infrared body temperature detecting device is (z-d 1).
It will be appreciated that the image capture module may also be a monocular camera, using the monocular camera in combination with sensor ranging, depth information of the user's facial image to determine the distance between the user and the body temperature detection device.
Fig. 3 is a flowchart illustrating a body temperature detection method according to an exemplary embodiment of the present disclosure, and as shown in fig. 3, the body temperature detection method includes the following steps.
In step S201, a distance between the user and the body temperature detection device is determined based on depth information of a face image of the user with an image capturing module.
In step S202, when the distance does not exceed the preset body temperature detection distance threshold, the temperature measurement module is controlled to obtain body temperature data of the user.
In step S203, a face image of the user is captured by the image capturing module.
In step S204, the identity of the user is determined based on the facial image.
The identity of the user is determined based on the facial image acquired by the image acquisition module, and the identity of the user can be determined by performing feature extraction based on the acquired facial image and comparing the feature extraction with the face in the facial image library. It is to be understood that the method for determining the identity of the user based on the facial image may also be other common methods in the face recognition technology, and the present disclosure does not limit the method for determining the identity of the user based on the facial image.
In step S205, when the identity of the user is verified, body temperature data is recorded based on the identity.
In an embodiment of the present disclosure, the body temperature detection device is applied to devices such as intelligent attendance, intelligent entrance guard, for example, when the body temperature detection device is applied to an intelligent attendance device, when the identity of the user passes the verification, the attendance record can be performed. When the attendance is recorded, the body temperature data of the user is correspondingly recorded based on the identity of the user passing the verification, the body temperature detection is realized while the attendance is performed, the operation of body temperature detection is simple and convenient, and the accuracy of body temperature detection is ensured.
For another example, when the body temperature detecting device is applied to an intelligent access control device, the user can access the access control device when the identity of the user is verified. When entering the entrance guard area, the body temperature data of the user is correspondingly recorded based on the identity of the user passing the verification, the body temperature detection is realized while the user enters the entrance guard area, and the environmental safety of the public area is ensured.
Fig. 4 is a flowchart illustrating a body temperature detection method according to an exemplary embodiment of the present disclosure, and as shown in fig. 4, the body temperature detection method includes the following steps.
In step S301, a distance between the user and the body temperature detection device is determined based on depth information of a face image of the user with an image capturing module.
In step S302, when the distance exceeds a preset body temperature detection distance threshold, the user is prompted to approach the body temperature detection device.
When the user position is far away from body temperature detection device, because body temperature detection device realizes the body temperature and detects based on the thermal radiation principle, when user's forehead facial distance exceeded predetermined body temperature detection distance threshold value, lead to the body temperature testing result inaccurate.
The user can be prompted to adjust the position, namely approach the body temperature detection device, through voice prompt, display characters and the like, so that the distance between the forehead of the user and the body temperature detection device does not exceed a preset body temperature detection distance threshold value, and an accurate body temperature detection result is obtained.
In step S303, when the distance does not exceed the preset body temperature detection distance threshold, the temperature measurement module is controlled to obtain body temperature data of the user.
The user is through the adjustment, and the distance between user's forehead position and the body temperature detection device is fit for carrying out the body temperature and detects, and control temperature measurement module obtains user's body temperature data.
In step S304, a face image of the user is captured by the image capturing module.
In step S305, the identity of the user is determined based on the facial image.
In step S306, when the identity of the user is verified, body temperature data is recorded based on the identity.
Fig. 5 is a flowchart illustrating a body temperature detection method according to an exemplary embodiment of the present disclosure, and as shown in fig. 5, the body temperature detection method includes the following steps.
In step S401, a distance between the user and the body temperature detection device is determined based on depth information of a face image of the user with the image capturing module.
In step S402, when the distance exceeds a preset body temperature detection distance threshold, the user is prompted to approach the body temperature detection device.
In step S403, when the amount of deviation of the face image from the preset body temperature detection position exceeds a preset threshold, the user is prompted to move in the left/right direction.
When the body temperature of the forehead part of the face of the user is detected, the middle part of the forehead is suitable for body temperature detection, and a correct body temperature detection result is obtained.
For example, a preset body temperature detection position may be displayed on the display screen, and when there is a large deviation of the facial avatar of the user from the preset body temperature detection position, that is, the difference between the part for performing body temperature detection and the middle of the forehead part is large. When the offset of the face image relative to the preset body temperature detection position exceeds a preset threshold, the accuracy of the body temperature detection result is poor.
The user can be prompted to adjust the position through voice prompt, display characters and the like, namely the head position is moved leftwards or rightwards, so that the left-right corresponding relation between the forehead part of the user and the body temperature detection device does not exceed the allowable range of the body temperature detection device, and an accurate body temperature detection result is obtained.
In step S404, when the distance does not exceed the preset body temperature detection distance threshold, the temperature measurement module is controlled to obtain body temperature data of the user.
In step S405, a face image of the user is captured by the image capturing module.
In step S406, the identity of the user is determined based on the facial image.
In step S407, when the identity of the user is authenticated, body temperature data is recorded based on the identity.
Fig. 6 is a flowchart illustrating a body temperature detection method according to an exemplary embodiment of the present disclosure, and as shown in fig. 6, the body temperature detection method includes the following steps.
In step S501, a distance between the user and the body temperature detection device is determined based on depth information of a face image of the user with an image capturing module.
In step S502, when the distance does not exceed the preset body temperature detection distance threshold, the temperature measurement module is controlled to obtain body temperature data of the user.
In step S503, a face image of the user is captured by the image capturing module.
In step S504, the identity of the user is determined based on the facial image.
In step S505, when the body temperature data exceeds the specified temperature threshold and/or the identity of the user is not verified, an alarm prompt is issued.
For example, when the user's identity is not verified, the user may be an illegal entry person without authority. In order to ensure safety, when an illegal entering person is found, a manager can be prompted to process the illegal entering person by sending an alarm sound, a voice prompt sound and the like. Or, the identity of the user is verified, but when the body temperature data exceeds a specified temperature threshold, the potential risk of infecting infectious diseases can exist. In order to ensure the health of other persons, the manager may be prompted to respond to an emergency.
When the body temperature data of the user is acquired based on multiple detections, the average value of the body temperature data detected multiple times can be compared with the specified temperature threshold, and when the average value of the body temperature data detected multiple times exceeds the specified temperature threshold, the body temperature of the user is determined to be abnormal, and an alarm prompt is sent. For safety, when the body temperature data detected for multiple times exceeds a specified temperature threshold, the body temperature of the user is determined to be abnormal, and an alarm prompt is given.
