Description

Analysis setting device and analysis setting method

Technical Field

The invention discloses an analysis setting device and an analysis setting method, and relates to the field of application of thermal image detection.

Background

When the subject thermal image needs to be analyzed, the user can set an analysis region of a point, a line, a plane, or the like for a specific portion of the subject thermal image to obtain an analysis result. For example, as shown in fig. 3(a), an analysis area selection column XZ3 is displayed on a display screen of a thermographic imaging device, a user may select analysis area composition data such as points, lines, frames, etc. from the selection column XZ3, and then position parameters of the analysis areas are set according to corresponding analysis portions of a thermal image of a subject in the displayed infrared thermal image, so as to set and obtain one or more analysis areas, and corresponding numbers such as S01, S02, and S03 may be automatically assigned to the sequentially set analysis areas according to a sequence of user operations.

The set analysis area can be analyzed by editing the analysis mode through operation; the analysis mode represents an analysis calculation rule used for analyzing the thermal image data determined based on the analysis area to obtain an analysis result, and is not limited to the calculation of the temperature value, and may be an analysis calculation rule related to various analyses of the thermal image data. For example, in the temperature analysis, the maximum temperature, the average temperature, the minimum temperature, the percentage content and the like are calculated, and the calculation relationship between the analysis areas, such as the temperature difference and the like, can also be included; for example, the calculation relationship between the analysis value obtained in the above embodiment and other specified parameters may also be used, for example, an analysis mode of calculating the relative temperature difference of the hot spot in the power industry; the relative temperature difference is (hot spot maximum temperature-normal phase maximum temperature)/(hot spot maximum temperature-temperature of the environmental reference); the temperature of the environmental reference body is an example of another predetermined parameter.

As shown in fig. 3(a), according to the connector corresponding to S01, the upper part and the lower part of the body sleeve corresponding to S02 and S03, according to the specific industry criterion, the analysis mode edited by the analysis area number, such as S01MAX, S02MAX-S03MAX, obtains the analysis result of the analysis value; further, an analysis pattern including a diagnosis rule (an example of a diagnosis rule including a comparison relationship between an analysis value obtained in the analysis region and a diagnosis value, and a diagnosis result corresponding to the comparison relationship) may be edited, for example, the analysis region S01 is normal for the linker region: s01MAX is less than or equal to 80 ℃; the method has the following defects: s01MAX is more than 80 ℃; the analysis zones S02, S03 correspond to the cannula site, normal: s02MAX-S03MAX is less than or equal to 2 ℃, and the defects are as follows: s02MAX-S03MAX is more than 2 ℃; the state of the object is determined by the analysis result thus obtained. Furthermore, the value range of the subdivided diagnostic value can be diagnosed to obtain further diagnostic results, such as '80 < S01MAX ≦ 110 ℃, serious defect', '110 ≦ S01MAX, critical defect'.

In the prior art, as shown in fig. 3, each analysis area in the analysis area setting column constitutes an identifier of data, and cannot express information related to an analysis mode; setting the analysis area and the analysis mode brings a series of problems;

for example, it is generally necessary to select the analysis area configuration data, and after the analysis area is set, the analysis mode setting operation is performed again.

For example, when the analysis region setting operation order is different, the parts of the subjects corresponding to the same-numbered analysis regions may not coincide; as shown in fig. 3(b), the user sets the analysis regions S01, S02, S03; however, in fig. 3(a) and 3(b), the analysis regions S01, S03 with the same numbers set correspond to different locations in the subject thermal image, and the analysis mode and the diagnostic rule compiled for fig. 3(a) are not applicable to the analysis regions in fig. 3 (b). As a result, in the prior art, it is necessary to rearrange the analysis pattern according to the number of the analysis area in fig. 3(b) for the analysis area set in fig. 3(b), and the operation is very complicated.

Therefore, it is understood that there is a need for an analysis setup device that solves the problems of the prior art.

Preferably, a presentation mode corresponding to the diagnosis result is embodied; as shown in FIG. 4 (f); the display state of the analysis area corresponding to the diagnosis result is represented as a real frame or a virtual frame, and the display modes are various, such as color, transparency, filling color, display or not, flashing, sound alarm and the like of the analysis area.

Preferably, the diagnosis result is embodied, as shown in fig. 4 (g); the method is convenient for users to select, and can further display remark information which embodies the diagnosis result, such as diagnosis basis, defect type, defect degree, treatment suggestion and the like.

More preferably, the mark represents information related to the part information; the site information "linker" as shown in FIG. 4 (h).

The part information may be information of a part, an angle, a shooting part, and the like, for example; preferably, the information includes at least information of the component, the imaging region, or the component and the imaging region; in one example, the part information may be part information of the object such as a joint, a sleeve, a base, and the like; preferably, the location information may include various classification information suitable for industrial applications, such as voltage level, phase, etc.; in another example, the region information may be shooting region information of the subject such as up, middle, down, and the like; in another example, the location information may also be combined information of component information and shot locations or angles, such as upper casing, lower casing, etc., and the location information may also be a subdivision of component types such as a joint that may be classified as a T-clamp, crimp tube, parallel groove clamp, etc.; for parts involving different analyses, comparisons, and the like, different part information should be prepared; various kinds of site information can be prepared in advance as necessary. The part information may include one or a combination of letters, icons, numbers, and the like.

In one example, an identifier that embodies the analysis pattern is caused to be displayed based on information about the analysis pattern stored in a storage medium; a preferred example of the identification stored in the storage medium, the identification of the corresponding analysis pattern, and the analysis area configuration data corresponding to the analysis pattern will be described with reference to the table shown in fig. 5.

Preferably, the analysis area related to the thermal image data is set according to the selected identifier and the position parameters set by the user. Since the mark corresponds to the analysis mode, when the mark does not relate to the analysis area configuration data, for example, default configuration data such as "frame" may be used to set the analysis area according to the position parameter set by the user; when the selected mark is associated with the analysis area configuration data, the analysis area can be set using the configuration data in accordance with the position parameter set by the user. In another example, the analysis area may be set by a user setting analysis area composition data, by default or by selecting location parameters identifying the associated analysis area.

Further, the control unit 11 is used as an analysis unit for analyzing the thermal image data according to the analysis mode corresponding to the selected identifier and the analysis area correspondingly set.

In one example, the thermal imagery data is converted to temperature values for analysis; without being limited thereto, for example, a case where analysis is performed by conversion into a radiant energy value, a gray value, a radiation rate value, or the like; obviously, the acquired thermal image data is analyzed, and is not limited to single-frame thermal image data, for example, multi-frame thermal image data stored in the temporary storage unit 6, or multi-frame thermal image data is subjected to integral operation to obtain one frame of processed thermal image data for analysis; the present invention is equally applicable to these situations. The technique for the detailed processing of the thermographic analysis is a technique well known to those skilled in the art, and the description is omitted.

Further, the control section 11 functions as a presentation section for presenting the set analysis region and its corresponding analysis result. For example, the presentation is performed in a display manner, and the presentation process is not limited to the display, and may be performed in various forms of "sound, light, electricity, vibration". For example, the analysis area and the analysis result corresponding to the analysis area are presented by an audio alarm, for example, a predetermined destination is transmitted.

The specific operation and control flow of embodiment 1 will be described in detail below. The application scene photographs, for example, a subject of a substation. After the power is turned on, the control unit 11 initializes the internal circuit, and then enters a shooting mode, that is, the shooting unit 1 obtains thermal image data by shooting, the image processing unit 2 performs a predetermined process on the thermal image data obtained by shooting by the shooting unit 1 and stores the data in the temporary storage unit 6, and the control unit 11 performs a control of the display control unit 3 so that the infrared thermal image is continuously displayed on the display unit 4 in the form of a dynamic image and a selection column XZ7 of the identifier is displayed, as shown in fig. 7 (a).

The control procedure of embodiment 1 is explained with reference to the flowchart of fig. 6. Fig. 7 is a schematic view of a display interface for setting and analyzing an analysis region of a subject thermal image.

Step A01, displaying a dynamic infrared thermal image on the display part 4, and displaying an identified selection column XZ7, as shown in FIG. 7 (a); according to the identifier 1 and the identifier 2 in fig. 5, an identifier 701 (obtained according to the identifier 1 in fig. 5) and an identifier 702 (obtained according to the identifier 2 in fig. 5) are displayed, and corresponding analysis modes and related analysis area configuration data are embodied; and displaying the infrared thermal image and the identification on the same display screen. The user can recognize the analysis mode represented by the mark of the selection column XZ7 and the related analysis area composition data according to the displayed object thermal image, and select the mark according to the requirement; the displayed marks may be one or more marks, and preferably, a plurality of marks each representing a mark corresponding to a different meaning are displayed, and may be different in analysis mode (for example, one of a plurality of constituent factors in analysis mode 1 and diagnosis rule 1 may be different), analysis region constituent data, position parameters of the analysis region, and the like; when the number of selectable identifiers is large, the display can be switched by an arrow 703.

The infrared thermal image and the mark are not limited to be displayed together, and the infrared thermal image and the mark can be displayed in a switching mode.

In step a02, the control unit 11 sets an analysis region based on the selected marker and the position parameter of the analysis region set by the user.

According to the analysis region configuration data associated with the selected identification, the analysis region configuration data is used as the analysis region configuration data related to the set analysis region; then, the user can set the position parameters (such as the position, or the size, or the rotation angle, etc.) of the analysis area in the infrared thermal image, and can input the numerical value of the specific position parameters by pressing the keys of the operation part 10, or input the position parameters by moving the position of the set analysis area by the operation part 10; preferably, the position parameters are set by means of the touch screen 3.

For example, the flag 701 is selected to set the obtained analysis region S01, and the flag 702 is selected to set the obtained analysis regions S02, S03. In this example, the numbers of the analysis regions may be generated according to the front-to-back order of the settings, such as S01, S02, S03; in one example, the number is attached to the analysis region configuration data corresponding to the identifier, and the number of the analysis region is obtained from the number of the analysis region configuration data corresponding to the analysis region. In one example, when the mark is associated with the part information, the part information may also be used as the number of the analysis area, or the number of the analysis area may be obtained according to the part information, such as pinyin abbreviation of the part information; in one example, there may be no number, and the set analysis region may be analyzed according to the selected identified analysis mode.

Preferably, the control unit 11 may associate the set analysis region with information related to the analysis pattern corresponding to the selected identifier (for example, analysis pattern corresponding to the identifier, or identification information of the identifier such as an identifier ID number), and may store the associated information in a predetermined region of the temporary storage unit 6, or may store the associated information in another storage medium such as the flash memory 9. In this way, during analysis, based on the analysis of the analysis area, the analysis pattern corresponding to the mark can be obtained from the information associated with the analysis area, and analysis can be performed.

As described above, the technical problem of the existing analysis area setting is solved, and the set analysis area is standard and is simple to operate. The setting of the analysis mode and the operation of selecting the analysis region configuration data can be completed by one operation, for example; and facilitates analysis according to a pre-programmed analysis pattern; in addition, because the mark is associated with the analysis mode in advance, the workload of arranging the analysis mode is small, and the requirement on a user is reduced. When the mark represents the diagnostic value, the diagnostic conclusion and the like corresponding to the analysis mode, the user can select and use the mark according to the analysis requirement.

And further, the analysis part is used for analyzing the thermal image data based on the correspondingly arranged analysis area according to the analysis mode corresponding to the selected identifier to obtain an analysis result. Wherein the analysis unit further comprises a diagnosis unit for performing analysis in a predetermined analysis mode to obtain an analysis result, the analysis mode including a diagnosis rule, and the analysis result including a diagnosis result. When the analysis is performed using the analysis mode having the diagnosis rule, the analysis result with the diagnosis result can be obtained, as shown in fig. 7(b), the analysis values and the diagnosis results corresponding to the analysis regions S01, S02, S03 are displayed: "S01 MAX: 90, defect "," S02 MAX: 25, normal "," S03 MAX: 25, normal "; this result can be obtained from the corresponding analysis mode identified in the table in fig. 5.

Further, the recording part is used for associating and recording the specified recording information with the thermal image data and/or data obtained after the thermal image data is subjected to specified processing; the specified record information comprises information related to an analysis area, information related to an analysis mode corresponding to the selected identifier and/or an analysis result obtained by analyzing the analysis area according to the analysis mode; the analysis area is set correspondingly according to the selected identification. Information on the analysis area, such as analysis area composition data and/or analysis area position parameters, related to the analysis area; information about the analysis mode corresponding to the selected identifier, for example, identification information of the identifier such as an identifier ID number, an analysis mode, and the like.

The recorded thermal image data and/or data obtained after performing prescribed processing on the thermal image data, for example, thermal image data obtained by reading a signal by an infrared detector in response to the time (or other prescribed time) indicated by the recording, or thermal image data temporarily stored in the temporary storage 6 (the prescribed thermal image data may be selected when multiple frames of thermal image data are stored); for example, the thermal image data in the above case is data obtained after predetermined processing (one or more of predetermined processing such as correction, interpolation, pseudo color, conversion to a temperature value, pixel reduction, compression, analysis to obtain an analysis result, and the like); for example, recording thermal image data of a prescribed number of frames; for example, thermal image data (frames) obtained by performing predetermined processing on a predetermined number of frames of thermal image data, for example, integrating the thermal image data of the plurality of frames stored in the temporary storage unit 6 to obtain one frame of thermal image data after the processing; for example, one or more of thermal image data obtained in these cases may be used, such as simultaneously recording the temperature value of each pixel obtained from the thermal image data and the image data of the infrared thermal image.

When the record key is pressed, the data obtained after the specified record information and the thermal image data and/or the thermal image data are subjected to specified processing are controlled to be recorded in an associated mode, for example, a thermal image picture file is generated and recorded in the memory card 8, and when the thermal image picture file is analyzed subsequently, the analysis result can be obtained through analysis of the specified record information associated with the thermal image picture file.

In an example, in response to the recording operation of the operating unit 10, the control unit 11 reads the signal from the infrared detector to obtain thermal image data, and causes the image processing unit 2 to compress the thermal image data, so that the predetermined recording information in the temporary storage unit 6 is associated with the compressed thermal image data to generate a thermal image file, which is recorded in the memory card 8. In addition, the association recording process may record the predetermined recording information in an information file or an index file related to the thermal image file, and the control unit 11 may generate the information file or the index file. The essence of the association record is to record information about the analysis area, and the analysis pattern and/or analysis results required to facilitate subsequent batch analysis.

In another example, the thermal image recording unit continuously records the captured thermal image data to generate a multi-frame thermal image file including a plurality of frames of thermal images, wherein when a recording instruction associated with specified recording information is provided, the control unit 11 controls the recording unit to read signals from the infrared detector to obtain thermal image data, compress the thermal image data and perform corresponding processing, so that the specified recording information in the temporary storage unit 6 and the compressed thermal image data are stored in the multi-frame thermal image file in an associated manner, wherein a frame timing position of the frame of thermal image data can be associated with the specified recording information and stored in an index area of the multi-frame thermal image file, and then subsequent dynamic recording processing is continued.

Example 2

In embodiment 1, the selectable identifiers can be selected for all the subjects to be photographed, and when there are many subjects to be photographed, there may be many identifiers to be selected. For this purpose, in embodiment 2, the control section 11 functions as a subject information selection section for selecting subject information, and the storage medium stores the subject information and its associated information relating to the identification; an identifier display control section for, based on the selected subject information, associating information related to an identifier with the subject information; controlling to cause the display of the logo. Embodiment 2 takes a portable thermal imaging device 13 with a photographing function as an example of an analysis setting device, referring to the structure of the thermal imaging device 13 of fig. 1.

Referring to the table shown in fig. 8, information such as (at least one) subject information, one or more markers associated with the subject information, an analysis pattern associated with each marker, and the like is stored in a storage medium; thus, when the user selects the subject instruction information based on the live subject, the mark display control section displays the mark to be selected based on the subject information corresponding to the selected subject instruction information, thereby further simplifying the operation. Preferably, the storage medium stores (at least one) object information, one or more markers associated with the object information, analysis region configuration data associated with each marker, and an analysis pattern.

The object information is information related to an object and may include information such as object identity information related to the object; the generated object indication information should allow the user to recognize and understand the corresponding object, such as information representing the specific self-attribute of the object, such as the location, type, number, etc. of the object; in the example of the power industry application, the subject information includes subject identity information related to a subject which can be distinguished and understood by a user, such as information representing the specific self-attribute of the subject, such as the location, type, number and the like of the subject; in one example, the subject information includes information representing a location (e.g., a substation, a device area), a type (e.g., a type such as a transformer, a switch, etc., or further including a voltage class, or further including a model, or further including a manufacturer, or further including a manufacturing lot, etc.), a phase (e.g., A, B, C phase), and the like of the subject; in another example, the subject information contains only information such as the type or model of the subject; further, information such as the subject-related attribution unit, voltage class, importance level, manufacturer, performance, and characteristics, past imaging or inspection history, manufacturing date, lifetime, and ID number may be included. The object information may have various configurations depending on the application. In other examples, the correspondence relationship between specific keys and subject information may be preset, and the selection of the subject information is performed by operation of a specific key (such as a dial key).

The control procedure of embodiment 2 is explained with reference to the flowchart of fig. 9. Fig. 10 is a schematic view of a display interface for setting and analyzing an analysis region of a subject thermal image.

Step B01, the display section 4 displays a dynamic infrared thermal image and displays the object information column XZ10, as shown in fig. 10 (a); the subject instruction information in the subject information column XZ10 can be obtained based on the subject information stored in the storage medium, and is easy for the user to recognize and understand. Further, the user can turn a page of the object instruction information display (e.g., by adjusting a scroll bar). It should be noted that the displayed object indication information may generally only include information such as the location, type, and phase of the object, which is convenient for the user to recognize during shooting, and not all information of the object information is necessarily displayed.

Preferably, a wide screen (such as a 16: 9 wide screen) is adopted, so that prompt information such as shot object indication information and the like can be displayed together with the infrared thermal image and can not be superposed on the infrared thermal image (generally 4: 3); further, the object indication information and the like may also be superimposed in the infrared thermal image.

In step B02, when the user photographs the object 1, the object 1 is selected, the logo selection column XZ11 is displayed, and the logo 1001 and the logo 1002 are displayed based on the logo information associated with the object 1. As shown in fig. 10 (b);

step B03, from which the user can select and set the analysis zone; for example, the flag 1001 is selected to set the acquisition analysis region S01; selecting marker 1002 to set the acquisition analysis region S02, S03; further, there may be only one mark associated with the object information, and in this case, the user may not need to perform a selection operation.

Then, in step B04, analysis processing is performed according to the analysis mode associated with the selected identifier and the corresponding analysis region.

When a user shoots other shot objects, selecting other shot object information, and displaying an identification selection column associated with the selected shot object information; obviously, the number of the displayed marks can be greatly reduced, so that the set analysis area is further normalized, and the method has the advantages of simple operation.

When a recording instruction is given, the recording part records the specified recording information and the thermal image data in a correlated manner, wherein the specified recording information and the thermal image data contain the selected shot object information, and therefore subsequent sorting and analysis can be facilitated. .

As described above, by selecting the subject information and the identifier, the set analysis area is further standardized and simple to operate, and when the subject information, the identifier and the like are recorded in association with the thermal image data and the like, the subsequent batch analysis is further facilitated.
