The embodiment of the disclosure provides a temperature measuring method, which can measure temperature of a calibration reference object to obtain temperature measurement data, and further verify the accuracy of temperature compensation according to the temperature measurement data, because a face image is arranged on the calibration reference object, and a temperature adjusting device capable of adjusting the temperature of the face image is arranged at a preset position of the face image, so that the calibration reference object can present different temperatures by adjusting the temperature of the temperature adjusting device, and further people with different body surface temperatures can be simulated by the calibration reference objects with different temperatures.
Fig. 1 shows a flowchart of a temperature measurement method according to an embodiment of the present disclosure, which may be performed by an electronic device having a thermal imaging data analysis function, such as a terminal device, a server or a thermal imager, where the terminal device may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, an in-vehicle device, a wearable device, or the like, and the method may be implemented by a processor calling a computer readable instruction stored in a memory. Alternatively, the method may be performed by a server.
As shown in fig. 1, the temperature measuring method may include:
in step S11, a color image and a temperature image of a calibration reference object are collected, a face image is disposed on the calibration reference object, and a temperature adjustment device capable of adjusting the temperature of the face image is disposed at a preset position of the face image.
For example, the calibration reference object may be composed of a face image and a temperature adjustment device, the temperature adjustment device may adjust the temperature of the calibration reference object in response to the control of the user for the temperature, and the temperature adjustment device is disposed at a preset position of the face image. For example, the temperature adjustment device has a heating target surface, and the temperature adjustment device heats through the heating target surface, and the heating target surface of the temperature adjustment device can be arranged at a preset position of the human face image.
Illustratively, the face image may comprise a photograph of a size consistent with a real face, with five sense organs in focus. The preset position can be the forehead position in the face image, and the temperature adjusting device in the calibration reference object is arranged at the forehead position of the face image. For example: the region corresponding to the forehead of the eyes in the face image can be cut or folded, and the temperature adjusting device and the cut or folded face image are fixed together, so that the temperature adjusting device is positioned at the forehead of the eyes in the face image (refer to fig. 2). For example, in the calibration reference object shown in fig. 2, the heating target surface of the temperature adjusting device is located at the forehead position in the face image.
For example, the calibration reference object may be placed within an imaging viewing angle range of the first electronic device, for example, facing the first electronic device, and collected at a preset distance from the first electronic device (the preset distance is a preset distance, which is not specifically limited in this disclosure, for example, the preset distance may be 0.8 meter, refer to fig. 3). Or, in the case that the first electronic device has the human body living body detection function, the color image and the temperature image of the calibration reference object may be acquired after the human body living body detection function is turned off by the first electronic device. The embodiment of the present disclosure is not particularly limited as to whether the first electronic device has the human body living body detection function.
Illustratively, the first electronic device may include an image capturing device for capturing a temperature image (e.g., a thermal infrared image), and an image capturing device for capturing a color image (e.g., color model images such as RGB (Red, Green, Blue, Red, Green, Blue), CMYK (Cyan, Magenta, Yellow, black), HSB (hue, saturation, brightness), and the like).
In step S12, performing face recognition on the color image of the calibration reference object, and identifying the preset position in the color image.
In step S13, a temperature measurement value of the calibration reference object is determined according to the temperature value corresponding to the preset position in the temperature image, so as to obtain temperature measurement data.
For example, the face recognition may be performed on the color image of the calibration reference object to recognize the preset position in the color image, so as to obtain the coordinate information of the preset position. For example: when the preset position is the forehead position, the coordinate information corresponding to the forehead position of the color image can be identified.
After the coordinate information of the preset position in the color image is obtained, the pixel value corresponding to the coordinate information corresponding to the preset position in the temperature image can be obtained, and the pixel value is the temperature value. And then, after the obtained temperature value is subjected to temperature compensation, a temperature measurement value of the calibration reference object is obtained to obtain temperature measurement data, wherein a display interface of the first electronic device for the temperature measurement value can be shown in fig. 4.
By analogy, the temperature of the temperature adjusting device in the calibration reference object is continuously adjusted, the temperature measurement value of the calibration reference object is collected (the temperature measurement process is referred to the temperature measurement value, and the embodiment of the disclosure is not repeated here), and a large amount of temperature measurement data can be obtained.
Therefore, the first electronic equipment can collect color images and temperature images of the calibration reference object, the calibration reference object is provided with the face image, and the preset position of the face image is provided with the temperature adjusting device capable of adjusting the temperature of the face image. The first electronic device can perform face recognition on the color image of the calibration reference object, recognize the preset position in the color image, and determine the temperature measurement value of the calibration reference object according to the temperature value corresponding to the preset position in the temperature image to obtain temperature measurement data. According to the temperature measurement method provided by the embodiment of the disclosure, people with different body surface temperatures can be simulated by adjusting the temperature of the calibration reference object, and the temperature of the calibration reference object is controllable, so that the embodiment of the disclosure can collect enough temperature measurement data in a time-saving and labor-saving manner, has a large data coverage, can reduce a test period, improves test efficiency, reduces test cost, and improves test precision.
In one possible implementation, the temperature control device may comprise a black body, which may be temperature controlled by a connected temperature control device.
The blackbody is a blackbody radiation source, can completely absorb external radiation energy, and can completely radiate an object with the energy, and the blackbody can generate standard radiation at a certain temperature. The black body can be connected with a temperature control device, and the temperature control device can be a terminal or other devices, such as: the temperature control device may be a user equipment, a mobile device, a user terminal, a cellular telephone, a cordless telephone, a handheld device, a computing device, etc. Illustratively, the black body and the temperature control device may be integrated in the same device. The user can set the temperature of the black body through the temperature control device, so that the black body can present different temperatures, and a large amount of temperature measurement data can be obtained.
In a possible implementation manner, the temperature adjusting device comprises a heating target surface, and the human face image at least exposes a partial area of the heating target surface.
For example, the temperature adjustment device may include a heating target surface that is a heating area of the temperature adjustment device, which in one possible implementation may be a black body. As shown in FIG. 2, the circular area on the temperature adjusting device is the heating target surface. In the calibration reference object, the temperature adjusting device is arranged at a preset position of the face image, and the face image at least exposes a partial area of the heating target surface. As shown in fig. 2, the face image covers a part of the heating target surface and exposes the rest of the heating target surface, and the face image may not cover the heating target surface and expose the heating target surface completely. Therefore, temperature measurement data are obtained by collecting the temperature of the partial region exposed out of the heating target surface, and the partial region is not shielded by the face image, namely the temperature is not influenced by the face image, so that the temperature collection accuracy of the first electronic equipment can be improved.
The circular area of the heating target surface is only an example of the embodiment of the present disclosure, and in fact, the embodiment of the present disclosure does not specifically limit the parameters of the shape, size, etc. of the heating target surface. In a possible implementation manner, in step S13, determining a temperature measurement value of the calibration reference object according to a temperature value corresponding to the preset position in the temperature image, to obtain temperature measurement data, may include:
determining a compensation temperature value according to a temperature value corresponding to the preset position in the temperature image;
and determining the temperature measurement value of the calibration reference object according to the temperature value corresponding to the preset position in the temperature image and the compensation temperature value to obtain temperature measurement data.
For example, after obtaining a temperature value corresponding to a preset position in the temperature image, the first electronic device may determine a corresponding compensation temperature value according to the temperature value. Exemplarily, a compensation temperature table can be preset, compensation temperature values corresponding to different temperature values are stored in the compensation temperature table, and the first electronic device can obtain the compensation temperature value corresponding to the temperature value from the compensation temperature table according to the temperature value after obtaining the temperature value. Or after the first electronic device obtains the temperature value, the compensation temperature value corresponding to the temperature value may be calculated by a compensation algorithm for calculating the compensation temperature value.
After the compensation temperature value corresponding to the temperature value is determined, the temperature value and the compensation temperature value may be fused to obtain a temperature measurement value of the calibration reference object, for example: the temperature value and the compensation temperature value can be accumulated to obtain a temperature measurement value of the calibration reference object, and then temperature measurement data can be obtained, wherein the temperature measurement data can comprise data such as the temperature measurement value and temperature measurement time.
In one possible implementation, the method further includes:
and uploading the temperature measurement data to second electronic equipment so that the second electronic equipment verifies the accuracy of the compensation temperature value according to the temperature measurement data.
For example, the second electronic device may be a terminal device or a server device. After the first electronic device obtains the temperature measurement data, the temperature measurement data can be uploaded to the second electronic device, and meanwhile, the temperature control device or the black body connected with the black body can send the temperature value of the black body to the second electronic device. The second electronic device can verify the accuracy of the compensation temperature value according to the temperature measurement data and the temperature value of the black body.
For example, the second electronic device may determine a difference between the temperature measurement value in the temperature measurement data and the temperature value of the black body, and verify the accuracy of the compensated temperature value according to the difference. For example: when the difference is greater than the difference threshold, it may be determined that the precision of the compensation temperature value is not verified, or when the difference is less than or equal to the difference threshold, it may be determined that the precision of the compensation temperature value is verified, where the difference threshold may be a preset value according to a requirement.
The second electronic device can adjust the compensation temperature value according to the accuracy of the compensation temperature value. Illustratively, the compensated temperature values may be adjusted individually, for example: can show the precision of each compensation temperature value through the difference, when the precision is greater than the precision threshold value, can adjust this compensation temperature value, for example: under the condition that the temperature value of the body of the calibration reference object is 37 ℃, the measurement value of the calibration reference object is 36.2 ℃, the corresponding compensation temperature value is 0.3, namely the measured temperature value is 36.5 ℃, under the condition that the accuracy threshold value is 0.3, the difference value between the temperature measurement value and the temperature value of the black body is 0.5, and the difference value is greater than the accuracy threshold value, the compensation temperature value corresponding to the temperature of 36.2 ℃ can be adjusted.
Or, the precision of the compensation temperature value can be represented by the mean value of the difference values corresponding to all the measurement data, and when the precision is greater than the precision threshold value, the algorithm for calculating the compensation temperature value can be adjusted and corrected to adjust the compensation temperature value.
The above examples are all examples of ways of adjusting the compensation temperature value, and are not understood to be limitations of ways of adjusting the compensation temperature value, and in fact, the embodiments of the present disclosure do not limit ways of adjusting the compensation temperature value. Therefore, the temperature measuring method provided by the embodiment of the disclosure can improve the accuracy of compensating the temperature value, and further improve the accuracy of temperature measurement.
In one possible implementation, the method may further include:
storing the temperature measurement data to a local storage area of the first electronic device;
and responding to the verification operation aiming at the compensation temperature value, and verifying the accuracy of the compensation temperature value corresponding to the at least one temperature measurement data stored in the local storage area.
For example, after obtaining the temperature measurement data, the first electronic device may store the temperature measurement data in a local storage area of the first electronic device, and meanwhile, the temperature control device or the black body connected to the black body may send the temperature value of the black body to the first electronic device, and the first electronic device may store the temperature value of the black body in the local storage area. When verification operation of a user for the compensation temperature value is received (for example, verification operation such as an operation control or an input command line instruction) the first electronic device may verify the accuracy of the compensation temperature value according to the temperature measurement data and the blackbody temperature value, and the specific verification process refers to the process of verifying the accuracy of the compensation temperature value by the second electronic device, which is not described herein again.
Or, in a case that a verification operation of the user for the compensation temperature value is received, the first electronic device may upload temperature measurement data stored in a local storage area of the first electronic device to the second electronic device through a Universal Serial Bus (USB), so that the second electronic device may verify accuracy of the compensation temperature value.
In a possible implementation manner, the method may further include:
and uploading temperature measurement data corresponding to the temperature measurement value of the calibration reference object to second electronic equipment under the condition that the temperature measurement value of the calibration reference object changes, or storing the temperature measurement data to a local storage area of the first electronic equipment under the condition that the temperature measurement value of the calibration reference object changes.
For example, the first electronic device may continuously perform temperature measurement on the calibration reference object, and monitor whether the temperature measurement value of the calibration reference object changes in real time. Under the condition that the temperature measurement value of the calibration reference object changes, the first electronic device can upload the temperature measurement data corresponding to the temperature measurement value of the calibration reference object to the second electronic device or store the temperature measurement data in a local storage area of the first electronic device, so that the problem of invalid occupation of the acquired temperature measurement data with the same measurement temperature value on resources can be solved, and the occupancy rate of the resources is reduced.
For example, the temperature control device connected to the black body may send temperature adjustment data to the second electronic device each time the temperature of the black body is adjusted, where the temperature adjustment data may include a temperature value of the adjusted black body and an adjustment time of the temperature value. After the first electronic device uploads the temperature measurement data to the second electronic device, the second electronic device can determine the temperature value of the black body and the temperature measurement value of the calibration reference object which are measured at the same moment according to the temperature measurement time corresponding to the temperature measurement data and the temperature adjustment time of the temperature value in the temperature adjustment data, and then can verify the accuracy of the compensation temperature value according to the temperature value of the black body and the temperature measurement value of the calibration reference object.
Or after the first electronic device stores the temperature measurement data in the local storage area of the first electronic device, the temperature control device connected to the black body may send temperature adjustment data to the first electronic device each time the temperature of the black body is adjusted. The first electronic device may determine a temperature value of the black body and a temperature measurement value of the calibration reference object, which are measured at the same time, and then verify accuracy of the compensation temperature value according to the temperature value of the black body and the temperature measurement value of the calibration reference object (the specific process may refer to the foregoing embodiment, and details of the embodiment of the present disclosure are not repeated here).
In one possible implementation, the temperature control device periodically controls its temperature according to a preset temperature control range.
For example, the temperature adjustment device may periodically adjust the temperature thereof according to a preset temperature, and for example, the temperature adjustment device includes a heating target surface, and the temperature adjustment device may periodically adjust the temperature of the heating target surface according to a preset temperature adjustment range. The temperature adjustment range can be preset temperature values. For example, the adjustment period may be set to 3 seconds, the preset temperature adjustment range may be set to 0.1 degree, that is, the temperature adjustment device may automatically increase the temperature by 0.1 degree every 3 seconds (or automatically decrease the temperature by 0.1 degree every 3 seconds), so that the first electronic device may continuously collect the temperature measurement data, the coverage of the collected test data is complete, and unattended continuous temperature measurement may be achieved.
In a possible implementation manner, the method may further include:
displaying the temperature image through a display interface of the first electronic device, wherein identification display is performed on the preset position in the temperature image.
For example, in the process of measuring the temperature, the first electronic device may display the collected color image and the temperature image through the display interface (as shown in fig. 4, the lower right corner area of the display interface in fig. 4 is the displayed temperature image). After the coordinates corresponding to the preset position in the color image are determined, the area corresponding to the preset position in the temperature image may be determined according to the determined coordinates, and the area corresponding to the preset position is subjected to identification display, where the identification display may highlight the preset position, for example: the area corresponding to the preset position may be identified with a color different from that of the surrounding area. As shown in fig. 4, the preset position of the temperature image is located at the center of the area corresponding to the heating target surface, the heating target surface appears in a highlight color in the area corresponding to the temperature image, and the preset position can be identified by a dark color different from the highlight color.
Therefore, in the temperature measurement process, whether the temperature measurement point (the preset position) of the calibration reference object is in the heating target surface of the temperature regulating device or not can be determined, so that the temperature measurement accuracy can be determined.
According to the temperature measuring method provided by the embodiment of the disclosure, the calibration reference object capable of simulating the human body surface temperature can be obtained only by matching the temperature adjusting device with the face image, so that the required temperature measuring data can be collected according to the calibration reference object, the required period is short, the data is accurate, the body surface temperature required by the test can be set, the test cost can be reduced, and the test precision is improved.
