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 application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
In order to facilitate understanding of the present application, the following first describes a method for generating a temperature measurement file proposed by the present application:
as can be seen from the above description, the current thermal imaging device has the functions of image capture and video recording, so in application, the thermal imaging device can operate in the image capture mode or the video recording mode. Based on this, the following describes the method for generating a thermometric file proposed in the present application from the thermal imaging device operating in the capture mode and the video recording mode, respectively:
firstly, when the thermal imaging device works in a capture mode, the thermal imaging device can acquire thermal imaging bare data (hereinafter referred to as thermal imaging picture bare data) of a frame of target scene, where the bare data refers to RAW data output by a movement of the thermal imaging device, and includes RAW data obtained by processing RAW data and RAW data obtained by processing the RAW data by a preprocessing algorithm, and the bare data refers to RAW data. When the thermal imaging device acquires the thermal imaging picture bare data of the target scene in the image capture mode, an offline temperature measurement picture can be generated according to the thermal imaging picture bare data and the temperature measurement information acquired when the thermal imaging picture bare data is acquired.
It should be understood that the original 14-bit gray scale data may also be used as bare data to generate an offline thermometric picture, and is not limited herein.
As an example, the offline temperature measurement picture can adopt a JPEG file format, and under the JPEG file format, the thermal imaging picture bare data can be written into an image information part of the JPEG file, and the temperature measurement information can be written into an additional information part of the JPEG file, so that the offline temperature measurement picture in the JPEG file format can be obtained.
In an embodiment of the present application, the temperature measurement information at least includes: temperature measurement parameters and calibration files configured for the thermal imaging device. Wherein, the temperature measurement parameter may include one or more of the following items: the temperature measurement method comprises the following steps of pseudo-color mode, temperature measurement range, ambient temperature, humidity, reflectivity and emissivity of a target object, temperature measurement distance between a lens on the thermal imaging device and the target object and the like. The calibration file contains the corresponding relation between the calibrated gray scale of the pixel point and the temperature.
In an optional implementation manner, the temperature measurement information may further include a temperature measurement rule, a fusion parameter, and the like.
The temperature measurement rule is a tool for indicating and selecting a temperature measurement area, and comprises rules such as points, lines, frames, polygons, circles and ellipses. For example, in a temperature measurement scene of a substation, temperature measurement is mainly performed on the connection point of the power equipment in the substation, so that a user can select the connection point of the power equipment through the temperature measurement rule of a circle in a preview image provided by the thermal imaging device to determine the connection point of the power equipment as a temperature measurement area.
The fusion parameters may then include parameters indicating that the thermal image and the visible light image are to be fused (as will be understood by those skilled in the art, the thermal imaging device may also have a visible light channel, and thus the thermal imaging device may also acquire the visible light image), such as parameters related to an image fusion method of multi-scale decomposition, parameters related to a pyramid transform fusion algorithm, parameters related to a wavelet transform fusion algorithm, and so on. As for the specific application of the fusion parameters, the detailed description is omitted here.
Therefore, the temperature measurement information contains the temperature measurement parameters configured when the thermal imaging device measures temperature in the target scene, so that the temperature measurement information can be used for restoring characteristic information of the target scene, such as the characteristics of the temperature, the humidity and the like of the target scene.
Secondly, when the thermal imaging device works in a video recording mode, the thermal imaging device can collect thermal imaging bare data (hereinafter referred to as thermal imaging video bare data) of a multi-frame target scene. When the thermal imaging device collects thermal imaging video bare data of a target scene in a video recording mode, an offline temperature measurement video can be generated according to the thermal imaging video bare data and temperature measurement information when the thermal imaging video bare data is collected.
In application, when the thermal imaging device operates in the video recording mode, the temperature measurement parameters and the calibration file set in the whole temperature measurement process may be unchanged or may be changed, for example, in the temperature measurement process of the thermal imaging device, a user manually modifies the configured temperature measurement parameters of the thermal imaging device or changes an external shield of the thermal imaging device (as can be understood by those skilled in the art, when the external shield is modified, the calibration file may be changed together). Based on the above, when the thermal imaging device works in the video recording mode, the video frame bare data and the temperature measurement information during the collection of the video frame bare data can be recorded by taking a frame as a unit, and finally, the offline temperature measurement video is generated according to all the collected video frame bare data of the target scene and the recorded temperature measurement information.
As an embodiment, in order to ensure accurate recording of temperature measurement information, the thermal imaging device may record the temperature measurement information at a specified position of the video frame bare data every time one video frame bare data is acquired, that is, the video frame bare data is acquired.
As an example, the specified location may be a header or a trailer of the video frame naked data.
As another embodiment, in order to save the storage space of the thermal imaging device, the thermal imaging device may record, when the first video frame bare data is collected, the temperature measurement information when the video frame bare data is collected at the specified position of the video frame bare data; and when non-first video frame bare data is collected, determining whether the temperature measurement information when the video frame bare data is collected currently and the temperature measurement information when the last video frame bare data is collected before are changed, if so, recording the changed temperature measurement information at the specified position of the video frame bare data, and if not, recording the temperature measurement information.
How the thermal imaging device determines whether the temperature measurement information when the bare data of the video frame is acquired before and the temperature measurement information when the bare data of the previous video frame is acquired before change is described as follows:
as one embodiment, the thermal imaging device may be configured with a temperature measurement information flag for indicating whether temperature measurement information has changed, wherein the temperature measurement information flag indicates that the temperature measurement information has changed when the temperature measurement information flag has a first value and indicates that the temperature measurement information has not changed when the temperature measurement information flag has a second value. As will be appreciated by those skilled in the art, initially, the thermometry information flag defaults to a second value.
Based on the above description, in the temperature measurement process, if the thermal imaging device detects that the temperature measurement parameter and/or the calibration file changes (may be changed automatically or modified manually by a user), the temperature measurement information flag may be set to a first value to indicate that the temperature measurement information changes. Therefore, when the thermal imaging device collects the non-first video frame bare data, whether the temperature measurement information when the video frame bare data is collected currently and the temperature measurement information when the last video frame bare data is collected before are changed or not can be determined by detecting the configured temperature measurement information mark.
In addition, under the condition that the temperature measurement information changes, after the thermal imaging device records the changed temperature measurement information at the specified position of the video frame bare data, the temperature measurement information flag can be set to be a second value so as to ensure the smooth execution of the above process.
In addition, as an embodiment, before generating the offline thermometry picture or the offline thermometry video, if the remark information set by the user, such as text remark information or voice remark information, is detected, the thermal imaging apparatus may record the remark information set by the user together in the offline thermometry picture or the offline thermometry video. Through the processing, the subsequent user can conveniently search the stored offline temperature measurement picture or offline temperature measurement video.
So far, the related description of the temperature measurement file generation method provided by the application is completed.
As can be seen from the above description, since the temperature measurement information configured in the temperature measurement process of the thermal imaging device is recorded in the offline temperature measurement picture and the offline temperature measurement video, when the user backtracks the temperature measurement scene through the offline temperature measurement picture and/or the offline temperature measurement video, the characteristic information of the target scene during temperature measurement can be restored through the temperature measurement information, and the user experience is improved.
The following explains a method for displaying a temperature measurement file proposed by the present application:
for ease of understanding, the system architecture illustrated in FIG. 1 is shown first.
As shown in fig. 1, includes a device 110, a thermal imaging device 120. Device 110 and thermal imaging device 120 may have a communication link therebetween, such as a wireless link, a wired link, or a fiber optic cable, without limitation.
The following describes a method for displaying a temperature measurement file provided by the present application by using a specific embodiment:
referring to fig. 2, a flowchart of an embodiment of a thermometry file display method according to an exemplary embodiment of the present application is provided, and in one example, the method may be applied to a display control device, such as the device 110 illustrated in fig. 1, and includes the following steps:
step 201: receiving a viewing instruction, and executing step 202 when the viewing instruction is used for indicating to view the offline temperature measurement picture; when the viewing instruction is used for indicating to view the offline thermometry video, step 203 is executed.
Step 202: and determining a target offline temperature measurement picture according to the viewing instruction, analyzing the target offline temperature measurement picture to obtain thermal imaging picture bare data and temperature measurement information, displaying the thermal imaging picture bare data through a first position of the display screen, and displaying the temperature measurement information through a second position of the display screen.
Step 203: and determining a target offline temperature measurement video according to the viewing instruction, analyzing the target offline temperature measurement video to obtain thermal imaging video bare data and temperature measurement information, displaying the thermal imaging video bare data through a first position of the display screen, and displaying the temperature measurement information through a second position of the display screen.
The following describes steps 201 to 203 collectively:
as an embodiment, the user may browse through the display control device a temperature measurement file list, which may include file information, such as name, modification time, type, size, and the like, of all offline temperature measurement pictures and offline temperature measurement videos saved by the thermal imaging device. As shown in fig. 3, is an example of a thermometry file list.
As an embodiment, after the user selects a target offline temperature measurement picture or a target offline temperature measurement video to be viewed, a viewing instruction may be triggered by a setting operation, for example, clicking or double clicking file information in a temperature measurement file list. After receiving the viewing instruction, the display control device may obtain the target offline temperature measurement picture or the target offline temperature measurement video indicated by the viewing instruction from the thermal imaging device through the communication link, or may obtain the target offline temperature measurement picture or the target offline temperature measurement video indicated by the viewing instruction locally. As can be understood by those skilled in the art, after receiving the viewing instruction, the display control device can locally obtain the target offline temperature measurement picture or the target offline temperature measurement video indicated by the viewing instruction on the premise that: and the display control equipment acquires the target offline temperature measurement picture or the target offline temperature measurement video from the thermal imaging equipment before receiving the viewing instruction.
When the viewing instruction is used for indicating to view the target offline temperature measurement picture, the target offline temperature measurement picture can be analyzed based on the file format adopted by the target offline temperature measurement picture so as to obtain the thermal imaging picture bare data and the temperature measurement information, then the thermal imaging picture bare data is displayed through the first position on the display screen, and the temperature measurement information is displayed through the second position on the display screen. For example, as shown in FIG. 4, an example of displaying content for a display screen.
Similarly, when the viewing instruction is used for instructing to view the target offline temperature measurement video, the target offline temperature measurement video can be analyzed based on the file format adopted by the target offline temperature measurement video to obtain the thermal imaging video bare data and the temperature measurement information, then the thermal imaging video bare data is displayed through the first position on the display screen, and the temperature measurement information is displayed through the second position on the display screen. The specific display effect is similar to that of fig. 4, and the detailed description is omitted here.
It should be noted that, as can be seen from the above description, the temperature measurement information is not necessarily recorded at the specified position of each video frame bare data in the thermal imaging video bare data, so that when the thermal imaging video bare data is displayed, for each video frame bare data in the thermal imaging video bare data, if the temperature measurement information is recorded at the specified position of the video frame bare data, the video frame bare data is displayed through the first position of the display screen, and the temperature measurement information is displayed through the second position of the display screen; if the temperature measurement information is not recorded at the specified position of the video frame bare data, the temperature measurement information analyzed last time before can be determined as the temperature measurement information when the thermal imaging equipment collects the video frame bare data, based on the temperature measurement information, the video frame bare data is displayed through the first position of the display screen, and the temperature measurement information displayed at the second position of the display screen is maintained. In addition, as an embodiment, in an application, a user may also modify a temperature measurement parameter displayed at the second position of the display screen, for example, when the user views an offline temperature measurement picture, the user finds that the configured ambient temperature of the thermal imaging device is wrong in the temperature measurement process, and at this time, the user may 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 at the second position of the display screen are modified, the temperature value corresponding to each pixel point in the bare data displayed at the first position of the display screen can be determined again according to the modified temperature measurement parameters and the calibration file.
Therefore, by the temperature measurement file generation method and the temperature measurement file display method, the temperature measurement parameters during temperature measurement can be optimized after the temperature measurement process is finished, so that the temperature value can be corrected, and the optimal effect of accurate temperature measurement can be achieved.
In addition, as another embodiment, as shown in fig. 4, a plurality of temperature measurement rules are displayed on a third position of the display screen, based on which, in an application, a user may select a target temperature measurement area in the bare data displayed on the first position of the display screen through the temperature measurement rules, for example, the user may select a temperature measurement rule needed by the user through a mouse tool, drag the selected temperature measurement rule into the bare data displayed on the first position, and further adjust the position and size of the selected temperature measurement rule through the mouse tool, thereby implementing the target temperature measurement area in the bare data displayed on the first position.
After the target temperature measurement area is selected, temperature measurement analysis can be performed on the target temperature measurement area according to a set temperature measurement analysis rule, and an analysis result is displayed.
As an example, the thermometric analysis rule may be: determining the highest temperature and the lowest temperature of a target temperature zone; or determining the average temperature of the target temperature measurement area, and the like, and the application does not limit the specific temperature measurement analysis rule. For example, as shown in fig. 4, the bare data displayed at the first position has an oval temperature measurement rule, and the maximum temperature of the target temperature measurement area is 39.4 degrees celsius and the minimum temperature is 29.6 degrees celsius by performing temperature analysis on the target temperature measurement area indicated by the temperature measurement rule according to the set temperature measurement analysis rule.
Therefore, by the temperature measurement file generation method and the temperature measurement file display method, the user can still set the required temperature measurement rule according to the actual requirement after the temperature measurement process is finished, the actual requirement of the user is met, and the user experience is improved.
So far, the description about the flow shown in fig. 2 is completed.
According to the embodiment, after the checking instruction for the target offline temperature measurement picture or the target offline temperature measurement video is received, the target offline temperature measurement picture or the target offline temperature measurement video is analyzed, and the analyzed naked data and the analyzed temperature measurement information are displayed on the display screen, so that a user can visually know the characteristic information of the target scene during temperature measurement.
