[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0033] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0034] It should be understood that although the terms first, second, third, etc., may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0035] To facilitate understanding of this application, the method for generating temperature measurement files proposed in this application will be explained first below:

[0036] As described above, current thermal imaging devices have image capture and video recording functions. Therefore, in applications, thermal imaging devices can operate in either image capture mode or video recording mode. Based on this, the temperature measurement file generation method proposed in this application will be explained below from the perspectives of the thermal imaging device operating in image capture mode and video recording mode respectively:

[0037] First, when the thermal imaging device is operating in capture mode, it can acquire a frame of raw thermal imaging data of the target scene (hereinafter referred to as raw thermal imaging image data). Generally, "raw data" refers to the original data output by the thermal imaging device's core, including the original 14-bit grayscale data and RAW data obtained after preprocessing algorithms. In this article, "raw data" refers specifically to RAW data. When the thermal imaging device acquires raw thermal imaging image data of the target scene in capture mode, it can generate an offline temperature measurement image based on this raw thermal imaging image data and the temperature measurement information at the time of acquisition.

[0038] It should be understood that the above-mentioned original 14-bit grayscale data can also be used as raw data to generate offline temperature measurement images, and this is not a limitation here.

[0039] As an example, the offline temperature measurement images mentioned above can be in JPEG file format. In JPEG file format, the raw data of the thermal imaging image can be written into the image information part of the JPEG file, and the temperature measurement information can be written into the additional information part of the JPEG file to obtain the offline temperature measurement image in JPEG file format.

[0040] In this embodiment, the aforementioned temperature measurement information includes at least: temperature measurement parameters configured for the thermal imaging device and a calibration file. The temperature measurement parameters may include one or more of the following: pseudo-color mode, temperature measurement range, ambient temperature, humidity, reflectivity and emissivity of the target object, and the temperature measurement distance between the lens on the thermal imaging device and the target object. The calibration file contains the calibrated correspondence between pixel grayscale and temperature.

[0041] In one optional implementation, the aforementioned temperature measurement information may also include temperature measurement rules, fusion parameters, etc.

[0042] Temperature measurement rules are tools used to indicate the selected temperature measurement area, including rules such as points, lines, boxes, polygons, circles, and ellipses. For example, in a substation temperature measurement scenario, the main focus is on measuring the temperature of the connection points of electrical equipment in the substation. Therefore, users can select the connection points of the electrical equipment using the circle temperature measurement rule in the preview image provided by the thermal imaging device, thus defining the connection points of the electrical equipment as the temperature measurement area.

[0043] The fusion parameters may include parameters used to indicate the fusion of thermal images and visible light images (those skilled in the art will understand that thermal imaging devices may also have visible light channels, and therefore thermal imaging devices may also acquire visible light images). Examples include parameters related to multi-scale decomposition image fusion methods, parameters related to pyramid transform fusion algorithms, and parameters related to wavelet transform fusion algorithms. The specific applications of the fusion parameters will not be elaborated upon in this application.

[0044] Therefore, since the temperature measurement information contains the temperature measurement parameters configured when the thermal imaging device measures the temperature in the target scene, the temperature measurement information can be used to reconstruct the characteristic information of the target scene, such as the temperature and humidity of the target scene.

[0045] Secondly, when the thermal imaging device is operating in video recording mode, it can acquire multiple frames of raw thermal imaging data of the target scene (hereinafter referred to as raw thermal imaging video data). When the thermal imaging device acquires raw thermal imaging video data of the target scene in video recording mode, it can generate an offline temperature measurement video based on the raw thermal imaging video data and the temperature measurement information at the time of acquisition.

[0046] In applications, when a thermal imaging device operates in video recording mode, the temperature measurement parameters and calibration files set throughout the temperature measurement process can remain unchanged or change. For example, during temperature measurement, the user may manually modify the configured temperature measurement parameters or change the external protective cover of the thermal imaging device (those skilled in the art will understand that when the external protective cover is changed, the calibration file may also change). Based on this, when the thermal imaging device operates in video recording mode, it can record raw video frame data and the temperature measurement information at the time of acquisition of the raw video frame data frame by frame. Finally, based on all the raw video frame data of the acquired target scene and the recorded temperature measurement information, an offline temperature measurement video is generated.

[0047] As an example, in order to ensure accurate recording of temperature measurement information, the thermal imaging device can record the temperature measurement information at a designated location in the raw data of each video frame it acquires.

[0048] As an example, the specified position can be the beginning or end of the raw data of a video frame.

[0049] As another embodiment, in order to save storage space of the thermal imaging device, the thermal imaging device can record the temperature measurement information at a designated position of the video frame raw data when the first video frame raw data is acquired; when a video frame raw data other than the first one is acquired, it can determine whether the temperature measurement information at the time of the current acquisition of the video frame raw data has changed from the temperature measurement information at the time of the previous acquisition of the video frame raw data. If so, the changed temperature measurement information is recorded at a designated position of the video frame raw data; if not, there is no need to record the temperature measurement information.

[0050] The following describes how a thermal imaging device determines whether the temperature information obtained when the raw data of a previously acquired video frame has changed compared to the temperature information obtained when the raw data of the previous video frame was acquired:

[0051] As one embodiment, the thermal imaging device may be configured with a temperature measurement information flag to indicate whether the temperature measurement information has changed. A first value indicates a change in the temperature measurement information, while a second value indicates no change. Those skilled in the art will understand that initially, the temperature measurement information flag defaults to the second value.

[0052] Based on the above description, during temperature measurement, if the thermal imaging device detects a change in the temperature measurement parameters and / or calibration file (which can change automatically or be manually modified by the user), it can set the temperature measurement information flag to the first value to indicate that the temperature measurement information has changed. Therefore, when the thermal imaging device acquires raw data from a video frame other than the first one, it can determine whether the temperature measurement information at the time of acquiring the current video frame raw data has changed compared to the temperature measurement information at the time of acquiring the previous video frame raw data by detecting the configured temperature measurement information flag.

[0053] Furthermore, if the temperature measurement information changes, the thermal imaging device can set the temperature measurement information flag to a second value after recording the changed temperature measurement information at a designated position in the raw video frame data, in order to ensure the smooth execution of the above process.

[0054] Furthermore, as an example, if the thermal imaging device detects user-defined annotations, such as text or voice annotations, before generating offline temperature measurement images or videos, it can record these annotations in the offline temperature measurement images or videos. This processing facilitates subsequent retrieval of saved offline temperature measurement images or videos by the user.

[0055] This concludes the description of the temperature measurement document generation method proposed in this application.

[0056] As can be seen from the above description, since offline temperature measurement images and videos record the temperature measurement information configured by the thermal imaging device during the temperature measurement process, when users review the temperature measurement scene through offline temperature measurement images and / or offline temperature measurement videos, they can restore the feature information of the target scene at the time of temperature measurement through the temperature measurement information, thereby improving the user experience.

[0057] The following describes the temperature measurement document display method proposed in this application:

[0058] To facilitate understanding, first show Figure 1 The system architecture shown in the example.

[0059] like Figure 1 As shown, the device includes device 110 and thermal imaging device 120. There may be a communication link between device 110 and thermal imaging device 120, such as a wireless link, a wired link or a fiber optic cable, etc., and this application does not impose any restrictions on this.

[0060] Device 110 may be a hardware device that supports network connectivity to provide various network services, including but not limited to smartphones, tablets, laptops, desktop computers, servers, etc. In this embodiment, device 110 may have a display screen to facilitate the application of the temperature measurement document display method provided in this application.

[0061] The temperature measurement document display method provided in this application is illustrated below through specific embodiments:

[0062] Please see Figure 2 This is a flowchart illustrating an embodiment of a temperature measurement document display method provided by an exemplary embodiment of this application. In one example, the method can be applied to a display control device, such as... Figure 1 The illustrated device 110 includes the following steps:

[0063] Step 201: Receive a viewing instruction. When the viewing instruction is used to indicate viewing offline temperature measurement images, proceed to step 202; when the viewing instruction is used to indicate viewing offline temperature measurement videos, proceed to step 203.

[0064] Step 202: Determine the target offline temperature measurement image according to the viewing command, parse the target offline temperature measurement image to obtain the raw thermal imaging image data and temperature measurement information, display the raw thermal imaging image data in the first position of the display screen, and display the temperature measurement information in the second position of the display screen.

[0065] Step 203: Determine the target offline temperature measurement video according to the viewing instruction, parse the target offline temperature measurement video to obtain thermal imaging video raw data and temperature measurement information, display the thermal imaging video raw data in the first position of the display screen, and display the temperature measurement information in the second position of the display screen.

[0066] The following provides a unified explanation of steps 201 to 203:

[0067] As one example, a user can browse a list of temperature measurement files via a display control device. This list can contain file information for all offline temperature measurement images and videos saved by the thermal imaging device, such as name, modification time, type, and size. Figure 3 The image shows an example of a list of temperature measurement files.

[0068] As one embodiment, after a user selects a target offline temperature measurement image or video to view, they can trigger a viewing command by setting an operation, such as clicking or double-clicking a file in the temperature measurement file list. Upon receiving the viewing command, the display control device can obtain the target offline temperature measurement image or video indicated by the viewing command from the thermal imaging device via a communication link, or it can obtain the target offline temperature measurement image or video indicated by the viewing command locally. Those skilled in the art will understand that the prerequisite for the display control device to obtain the target offline temperature measurement image or video indicated by the viewing command locally after receiving the viewing command is that the display control device has already obtained the target offline temperature measurement image or video from the thermal imaging device before receiving the viewing command.

[0069] When a view command is used to instruct the viewing of a target offline temperature measurement image, the image can be parsed based on its file format to obtain raw thermal imaging data and temperature information. The raw thermal imaging data is then displayed in the first position on the screen, and the temperature information is displayed in the second position. For example, ... Figure 4 The image shows an example of content displayed on a screen.

[0070] Similarly, when a view command is used to instruct viewing a target offline temperature measurement video, it can be parsed based on the file format used by the target offline temperature measurement video to obtain raw thermal imaging video data and temperature measurement information. Then, the raw thermal imaging video data is displayed in the first position on the screen, and the temperature measurement information is displayed in the second position on the screen. The specific display effect is similar to... Figure 4 Similarly, details will not be elaborated further in this application.

[0071] It should be noted that, as described above, temperature measurement information is not necessarily recorded at a designated location in each video frame of the raw thermal imaging video data. Therefore, when displaying the raw thermal imaging video data, for each video frame, if temperature measurement information is recorded at a designated location, the raw video frame is displayed at the first position of the display screen, and the temperature measurement information is displayed at the second position. If no temperature measurement information is recorded at a designated location, the most recently parsed temperature measurement information can be determined as the temperature measurement information when the thermal imaging device acquired the raw video frame. Based on this, the raw video frame is displayed at the first position of the display screen, while the temperature measurement information already displayed at the second position remains unchanged. Furthermore, as an example, in application, the user can also modify the temperature measurement parameters displayed at the second position of the display screen. For example, if a user finds that the ambient temperature configured for the thermal imaging device during the temperature measurement process is incorrect when viewing offline temperature measurement images, the user can modify the ambient temperature displayed at the second position of the display screen. When the display control device detects that the temperature measurement parameters displayed in the second position of the display screen have been modified, it can re-determine the temperature value corresponding to each pixel in the raw data displayed in the first position of the display screen based on the modified temperature measurement parameters and calibration file.

[0072] Therefore, by applying the temperature measurement file generation and display method provided in this application, it is possible to optimize the temperature measurement parameters after the temperature measurement process is completed, so as to correct the temperature value and achieve the best effect of accurate temperature measurement.

[0073] Furthermore, as another embodiment, such as Figure 4As shown, various temperature measurement rules are displayed in the third position of the display screen. Based on this, in the application, the user can select the target temperature measurement area from the raw data displayed in the first position of the display screen by using the temperature measurement rules. For example, the user can use the mouse tool to select the temperature measurement rule they need and drag it to the raw data displayed in the first position. Furthermore, the user can use the mouse tool to adjust its position and size, thereby achieving the selection of the target temperature measurement area from the raw data displayed in the first position.

[0074] After selecting the target temperature measurement area, you can also perform temperature measurement analysis on the target temperature measurement area according to the set temperature measurement analysis rules and display the analysis results.

[0075] As an example, the above temperature measurement analysis rules could be: determining the highest and lowest temperatures of the target temperature measurement area; or determining the average temperature of the target temperature measurement area, etc. This application does not limit the specific temperature measurement analysis rules. For example, such as... Figure 4 As shown, the raw data displayed in the first position contains an elliptical temperature measurement rule. According to the set temperature analysis rule, the temperature of the target temperature measurement area indicated by the temperature measurement rule is analyzed, and the highest temperature of the target temperature measurement area is 39.4 degrees Celsius and the lowest temperature is 29.6 degrees Celsius.

[0076] Therefore, by applying the temperature measurement file generation and display method provided in this application, users can still set the required temperature measurement rules according to their actual needs after the temperature measurement process is completed, thereby meeting users' actual needs and improving user experience.

[0077] This concludes the process. Figure 2 The process described is as follows.

[0078] As can be seen from the above embodiments, by receiving a viewing instruction for a target offline temperature measurement image or video, parsing the target offline temperature measurement image or video, and displaying the parsed raw data and temperature measurement information on the display screen, users can intuitively understand the characteristic information of the target scene during temperature measurement.

[0079] Corresponding to the aforementioned embodiments of the temperature measurement document generation method, this application also provides embodiments of a temperature measurement document generation device.

[0080] Please see Figure 5 This is a block diagram illustrating an embodiment of a temperature measurement document generation device provided in an exemplary embodiment of this application. The device is applied to a thermal imaging device and includes:

[0088] In one embodiment, the second generation module 52 determines whether the temperature measurement information when the raw data of the video frame is currently acquired has changed compared to the temperature measurement information when the raw data of the previous video frame was acquired, including:

[0089] The configured temperature measurement information flag is detected. When the temperature measurement information changes, the temperature measurement information flag is set to the first value; otherwise, the temperature measurement information flag is set to the second value.

[0090] When the temperature measurement information flag is detected to be the first value, it is determined that the temperature measurement information when the raw data of the video frame is currently collected has changed from the temperature measurement information when the raw data of the previous video frame was collected.

[0091] When the temperature measurement information flag is detected as the second value, it is determined that the temperature measurement information when the raw data of the video frame is currently collected has not changed from the temperature measurement information when the raw data of the previous video frame was collected.
