Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention in light of the teachings of the present embodiments, are within the scope of the present invention.
The ambient temperature is under change due to changes over time and the environment. Under different environmental temperatures, the temperature values measured for the target object with the same temperature are different, which causes a large error between the measured temperature value and the actual temperature value of the target object.
In a possible implementation manner, the temperature value measured by the temperature measurement module can be directly used as the final temperature measurement result.
In another possible implementation manner, a fixed compensation value may be added to the temperature value measured by the temperature measurement module, so as to obtain a final temperature measurement result.
However, the above two methods have different measured results for target objects with the same temperature under different environmental temperatures, and such measurement methods are neither accurate nor stable.
In yet another possible implementation, the temperature measurement module may be manually calibrated at regular intervals according to the ambient temperature.
However, the above method requires manual operation, which is inconvenient for the user.
In view of this, embodiments of the present application provide a method and an apparatus for temperature measurement, which use a difference between an ambient temperature value measured by a temperature measurement module and an ambient temperature value measured by a thermometer as a temperature calibration value to calibrate a temperature value of a target object measured by the temperature measurement module in real time and automatically, so that an accurate temperature measurement result of the target object can be obtained at different ambient temperatures, and accuracy of temperature measurement is improved.
Before describing the method for measuring temperature provided by the embodiments of the present application, the following description is made.
First, in the embodiments shown below, terms and acronyms such as temperature measurement module, temperature calibration value, etc. are exemplary examples given for convenience of description, and should not limit the present application in any way. This application is not intended to exclude the possibility that other terms may be defined in existing or future protocols to carry out the same or similar functions.
Second, the first, second and various numerical numbers in the embodiments shown below are merely for convenience of description and are not intended to limit the scope of the embodiments of the present application. For example, to distinguish between different ambient temperature data, etc.
Third, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, and c, may represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b and c can be single or multiple.
The temperature measuring method provided by the embodiment of the application can be applied to intelligent entrance guards for people to enter and exit in various companies, markets and communities, and can also be applied to body temperature monitoring systems of hospitals.
Illustratively, fig. 1 is a schematic flow chart of a method 100 for temperature measurement provided by an embodiment of the present application. As shown in fig. 1, the method 100 includes the steps of:
s101, the temperature measuring equipment acquires first environment temperature data displayed on the thermometer based on the camera.
In the embodiment of the application, the thermometer is arranged right in front of the temperature measuring equipment, and the camera can be used for shooting videos for the thermometer.
It should be understood that the first ambient temperature data measured by the thermometer may be considered as the true ambient temperature.
S102, the temperature measuring equipment acquires second environment temperature data.
It should be understood that the second ambient temperature is obtained by the temperature measurement module in the temperature measurement device.
Alternatively, the temperature measurement device may acquire the second ambient temperature data when no target object exists within the shooting range of the camera.
S103, the temperature measuring equipment determines a temperature calibration value based on the first environment temperature data and the second environment temperature data.
And S104, the temperature measuring equipment measures the temperature of the target object to acquire original measurement data.
And S105, the temperature measuring equipment uses the temperature calibration value to calibrate the original measuring data so as to obtain the temperature measuring result of the target object.
In the embodiment of the application, the temperature calibration value is determined through the first environment temperature data obtained by measuring with the thermometer and the second environment temperature data obtained by measuring with the temperature measurement module, so that the original measurement data of the target object measured by the temperature measurement module is automatically calibrated, and the accuracy of the temperature measurement equipment can be improved.
Temperature measurement equipment in this application embodiment is equipped with at least one in temperature measurement module, camera and the thermometer to temperature measurement module and camera can be installed inside temperature measurement equipment, and the thermometer can hang in the dead ahead of camera, with the reading of guaranteeing that the camera can normally shoot thermometer and thermometer demonstration.
It should be understood that the terms "provided", "mounted", "suspended" are to be interpreted broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The above-mentioned meaning belonging to the present application can be understood by those of ordinary skill in the art as the case may be.
For example, the temperature measurement module may include a temperature sensor and/or an infrared sensor, wherein the temperature sensor may be a temperature sensor such as a negative temperature coefficient, a thermocouple, or a resistance thermometer. The infrared sensor measures the temperature of a target object by using infrared rays of the surface of the object.
For example, when the infrared sensor is used for measuring the temperature of a human body, energy emitted by the human body is converged onto the infrared detector through the optical system, the detector converts incoming radiation into a voltage signal, and after the voltage signal is sent to the receiving system, the temperature of the measured human body is calculated through data processing and curve automatic fitting, and the temperature is displayed in a digital mode.
The thermometer may be a mercury thermometer or an electronic thermometer.
The mercury thermometer is one of the thermometers in expansion, the mercury thermometer is used for measuring the temperature, and the method is simple and visual and can avoid errors of an external remote thermometer.
The electronic thermometer can be composed of a temperature sensor, a liquid crystal display, a button cell, an application specific integrated circuit and other electronic components, can quickly read and accurately measure the temperature, and has the advantages of convenient reading, short measurement time, high measurement precision, memory, buzzing prompt and the like compared with a mercury thermometer.
The camera has the functions of video shooting/transmission, static image capture and the like, and can process and convert images into digital signals which can be identified by a computer through a photosensitive component circuit and a control component in the camera after the images are collected by a lens, and then the digital signals are input into the computer through a parallel port or a Universal Serial Bus (USB) and then are restored by software.
The camera described in the embodiments of the present application may be a digital camera or an analog camera. The digital camera can convert the analog video signal generated by the video acquisition equipment into a digital signal, and then store the digital signal in the computer. The video signal captured by the analog camera must go through a specific video capture card to convert the analog signal into a digital signal and compress the digital signal before the digital signal can be converted into a computer for use, and the digital camera can directly capture an image and then transmit the image to the computer through a serial port, a parallel port or a USB interface.
As an alternative embodiment, the temperature measuring apparatus, which obtains first ambient temperature data displayed on a thermometer based on a camera, includes: the temperature measuring equipment acquires a video of the thermometer through the camera; and the temperature measuring equipment analyzes the video to obtain the first environment temperature data.
In the embodiment of the application, the video shot by the camera can be analyzed by adopting a computer vision algorithm, and the thermometer and the reading of the thermometer are identified, so that the real environment temperature can be automatically acquired.
Computer vision algorithms aim at identifying and understanding contents in images or videos and mainly comprise five technologies of image classification, object detection, target tracking, semantic segmentation and instance segmentation.
As an alternative embodiment, the temperature calibration value is a difference between the first ambient temperature data and the second ambient temperature data.
In the embodiment of the application, the temperature measuring device determines the temperature calibration value by calculating the difference between the first ambient temperature data measured by the temperature measuring module and the second ambient temperature data measured by the thermometer.
It should be understood that, because the temperature values measured by the temperature measurement module are different for target objects with the same temperature under different environmental temperatures, the measured temperature has a larger deviation, and therefore the temperature measurement module needs to be calibrated by using the temperature calibration value, so that the accuracy of temperature measurement can be ensured.
As an alternative embodiment, the temperature measurement is the sum of the raw measurement data and the temperature calibration value.
In the embodiment of the application, the original measurement data measured by the temperature measurement module is added with the temperature calibration value, so that the accurate temperature values of the target object under different environmental temperatures can be obtained.
Illustratively, the first ambient temperature data is 35 ℃ (degrees celsius), the second ambient temperature data is 37 ℃, and the temperature calibration value is-2 ° from 35 ° to 37 °. When the temperature measuring equipment measures the temperature of a human body, the original measuring data obtained by the temperature measuring module is 38 ℃, and then the original measuring data can be calibrated by the calibration value of-2 ℃ to obtain the final temperature measuring result of the human body, namely 38 ℃ (+ (-2 ℃), 36 degrees.
Illustratively, fig. 2 is a schematic diagram of a temperature measurement system 200 provided in an embodiment of the present application. As shown in fig. 2, the system 200 includes a temperature measurement module 210, a raw measurement data reading module 220, a temperature calibration module 230, a temperature calibration value calculation module 240, a thermometer identification module 250, a thermometer 260, a camera 270, and a temperature use module 280.
The temperature measurement module 210 is configured to sample a temperature of a target object to obtain original measurement data.
The raw measurement data reading module 220 is used for reading raw measurement data from the temperature measurement module 210.
The thermometer identification module 250 identifies the thermometer 260 and the reading of the thermometer 260 from the video captured by the camera 270, and treats the reading as the true ambient temperature.
The temperature calibration value calculating module 240 is used to calculate the difference between the ambient temperature measured by the thermometer and the ambient temperature measured by the temperature measuring module, and update the difference as the temperature calibration value to the temperature calibration module 230.
The temperature calibration module 230 adds a temperature calibration value to the measured raw measurement data of the target object to obtain a final temperature measurement result 280.
Alternatively, the temperature calibration value calculation module 240 may periodically update the temperature calibration value to the temperature calibration module 230, or may update the temperature calibration value to the temperature calibration module 230 in real time.
It should be understood that the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
