Description
Technical Field
The invention discloses a selection device and a selection method, and relates to the field of application of infrared detection.
Background
The subject usually has a plurality of specific shooting positions, parts and angles, and in most cases, special shooting is not needed, but when a user shoots an overall infrared thermal image and finds a defect, the defect position needs to be shot specially. The shooting defect part is locally shot by the shooting defect part, and the shooting defect part is locally shot by the shooting defect part; the prior art does not describe how to distinguish the different situations of the above described shots.
For example, at present, a thermal image file captured by a thermal image capturing device generates a file name according to time or sequence number; for subsequent archiving and analysis, and distinguishing thermal image files corresponding to the shot object, when infrared detection is carried out, a user needs to correspondingly record the shot object information according to a field nameplate which is recognized by the shot object; there is a method of selecting subject information based on subject information stored in a thermal image capturing apparatus, and recording the selected subject information in association with an infrared thermal image, where the subject information is, for example, an identification name of a subject, information representing a location, a type, a number, and the like of the subject in the power industry, and information representing "equipment in substation 1 equipment area 1 ia phase" represented by a subject 1 in fig. 3.
However, when the user finds a defect while shooting the entire infrared thermal image, the user needs to take a special shot of the defective portion. At this time, if only the subject information is recorded in association with the thermal image data obtained by the shooting, the workload is very large in the subsequent processing, and the user generally needs to check and process the data one by one. Moreover, if such a method is adopted, when a plurality of thermal image files of the same object are processed in batch, confusion often occurs, for example, an analysis result of the entire thermal image of the object is "defect", and an analysis result obtained by specially shooting a defective portion is "critical defect", which should be counted as one defect or two different defects? Which analysis result is adopted as the quasi-woolen? Especially, when thermal image database management is performed, confusion of query, statistics and the like can occur.
Furthermore, a series of problems are posed for other aspects relating to photographing, such as transformation of an analysis mode, a reference image, and the like.
Therefore, it is appreciated that there is a need for a selection device that addresses the problems of the prior art.

The following description will be given taking, as an example, a whole shot in which a subject corresponding to selected subject information is selected, and a partial shot in which a subject corresponding to selected part information is selected:
among them, pseudo color processing, for example, pseudo color processing different from the whole object thermal image, such as changing a pseudo color range or a pseudo color, is performed on the captured partial object thermal image.
Among them, lens adjustment, for example, is performed on a captured partial object thermal image differently from the entire object thermal image, for example, since the shooting distance is usually different, corresponding focus adjustment is performed.
In this case, the adjustment processing of the visible light is performed for the local object thermal image captured by the imaging device, for example, because the angle of view is different when the imaging distance is different, and the adjustment of the lens angle of view is different from that of the entire object thermal image.
In the synthesis process, for example, when the local object thermal image is synthesized with the visible light, a synthesis process (such as a transparency, or a threshold value of fusion, a parameter for high-pass filtering the visible light, or the like) different from the entire object thermal image is performed on the captured local object thermal image.
And performing display processing on the reference image, for example, converting display position parameters of the reference image showing morphological characteristics in the infrared thermal image.
Wherein the analysis process, for example due to different shooting distances, transforms the analysis area and/or the analysis mode related to the analysis process; the analysis mode represents an analysis calculation rule adopted for analyzing thermal image data determined based on a specific analysis area to obtain an analysis result, for example, in temperature analysis, the maximum temperature, the average temperature, the minimum temperature, the percentage content and the like are calculated, or a calculation relation among analysis areas such as temperature difference and the like can be further included, or a rule for comparing and analyzing specified thermal image data is further included, or a diagnosis rule for diagnosing the analysis result to obtain a diagnosis result is further included, and the diagnosis rule includes, for example, a comparison relation between the analysis data obtained for the specific analysis area and a diagnosis threshold value and a corresponding diagnosis result; for example, rules including a comparison relationship between analysis data obtained for a specific analysis area and a predetermined value, and analysis results, corresponding diagnosis thresholds, diagnosis results, and the like. The analysis areas, such as the analysis areas of the points, lines, boxes, etc., may be preset by the user or prepared in the thermographic arrangement 13.
In the method, a shooting parameter (such as radiance, distance, ambient temperature, wind speed, etc.) is converted, for example, a distance parameter in the shooting parameter is converted due to a difference in shooting distance.
The presentation information conversion processing may be different depending on, for example, the imaging request of the whole or different parts of the subject, and the presentation information includes, for example, one of an imaging method, a detection criterion, and history information related to the detection of the subject, and is used to prompt the user to take an image with reference. The shooting method comprises the following steps: for example, the location, angle, etc. of the shot, whether three phases are shot simultaneously or the shot is shot in a single item, etc. The detection criterion is as follows: such as thresholds including thermographic signatures, fault signatures, temperature determinations, etc. History information is, for example, history of past shooting or inspection.
Among the above processes, the thermal imaging device 13, which is involved in the process of visible light, should have or be connected with a visible light photographing device. More specific embodiments of the above-described process are well known to those skilled in the art, and the description thereof is omitted.
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 display unit 4 continuously displays infrared thermal images in the form of dynamic images and displays a selection column XZ41 of subject information, as shown in fig. 4 (a).
Fig. 4 is a schematic view of a display interface for displaying and selecting subject information and selecting region information. The control procedure of embodiment 1 is explained with reference to the flowchart of fig. 5.
A01, in the shooting mode, the display part 4 displays dynamic infrared thermal image, displays the object information selection column XZ41 according to the object information stored in the storage medium, and the user can (such as by adjusting scroll bar) turn the page of the object information display. The site information selects menu item XZ 42. It should be noted that the displayed identifier of the object 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 the 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 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); furthermore, the object information can also be superimposed in an infrared thermal image.
A02, when the user selects "subject 1", shooting the subject corresponding to "subject 1"; the displayed object information "object 1" is displayed so as to be distinguished from other object information, for example, by underlining.
A03, when a recording instruction is given, performing associated recording on the specified thermal image data and the selected shot object information 'shot object 1';

Specifically, in one embodiment, in response to the recording instruction operation of the operating unit 11, the control unit 11 controls the infrared detector to read signals to obtain thermal image data, and causes the image processing unit 2 to perform predetermined thermal image data compression processing on the thermal image data, or performs predetermined processing such as correction and interpolation on the thermal image data, and then performs compression processing, associates the information related to the selected subject information in the temporary storage unit 6 with the compressed thermal image data, generates a thermal image file, records the thermal image file in the memory card 8, and ends the processing. Further, the compression may be performed after the information is added.
The information on the selected subject information may be, for example, all of the information of the subject information as the selected subject information, or part of the information.
Further, the association recording processing means that information relating to the selected subject information can be recorded in an information file or an index file associated with the thermal image file, or the like, which the control section 11 can generate; furthermore, a thermal image file name may be generated according to the selected subject information, and preferably, the recording unit has a file name generating unit, and the recording unit has a file name generating unit for generating a file name of the thermal image file, where the generated file name of the thermal image file includes information related to the selected subject information and/or selected part information; for example, when the entire subject 1 is selected to be photographed, the generated thermal image file name: subject 1. jpg; for example, when the joint region of the subject 1 is selected, the subject 1-joint.jpg; further, file names, such as subjects 1-20130207.jpg, are generated as combined with the time information "20130207"; the essence of the association record is to record the information needed for subsequent batch analysis, and the file name contains the object information to facilitate the user to view and the subsequent batch analysis to read and identify the object information in the file name.
A04, when the user needs to shoot the special part of the shot object, a menu item XZ42 can be selected;
a05, based on the region information associated with the "subject 1", causing the display region information selection column XZ43 to display region information "joint", "upper sleeve portion", and "lower sleeve portion" corresponding to the "subject 1"; the user can select corresponding part information from the position information, such as selecting a joint; as shown in fig. 4 (b).
A06, when a recording instruction is given, performing associated recording on the thermal image data at a specified time, the selected shot object information 'shot object 1' and the selected part information 'joint'; for example, the generated thermal image file, the thermal image file name: the object 1-joint jpg, the file name contains the object information and the part information, which is convenient for the user to check, and the subsequent batch analysis is convenient to read and identify the classification information in the file name, such as the object information and the part information.
When the overall thermal image of the shot object is shot, selecting shot object information, and when the local thermal image of the shot object is shot, selecting local part information; and corresponding association record is carried out, so that subsequent analysis and processing can be facilitated, and more comprehensive and rigorous processing results can be obtained.
Although the recording process is described as an example, it is apparent that various processes related to the subject whole shooting and the part shooting, for example, one or more of the above-mentioned various processes may be replaced with or included.
Example 2
The prescribed processing at least includes one or a combination of more of pseudo-color processing, shooting parameter conversion processing, analysis processing (acquisition processing of analysis numerical values, or diagnosis processing, or comparison analysis processing, etc.), classification processing, statistical processing, retrieval processing, and presentation processing.
The specific operation and control flow of embodiment 2 will be described in detail below. The application scene is used for shooting a shot object of a transformer substation, for example, the shot object information and the part information are selected in the shooting process, and the shot object information, the part information and the thermal image data are recorded as a thermal image file in a correlation mode; a prescribed processing of the individual thermal image files obtained by the recording is performed.
And step B01, acquiring thermal image data, such as acquiring a thermal image file to be processed from the memory card 8 according to the selection of a user.
Step B02, the subject information and the part information related to the frame of thermal image data are analyzed;
in step B03, the processing unit performs a predetermined process. For example, the processing such as display is performed based on the pseudo color associated with the part information.
In other embodiments, when processing the acquired multi-frame thermal image data (e.g., a plurality of thermal image files, such as a thermal image video file including a plurality of thermal image frames), the processing device may perform predetermined processing on the multi-frame thermal image data according to the analyzed object information and/or the analyzed part information, so as to obtain a processing result. For example, the processing of the multi-frame thermal image data, such as comparative analysis, classification, statistics, retrieval, presentation and the like, can be realized according to the analysis result obtained by the specific analysis area set by each thermal image data. Preferably, the predetermined processing is related to the subject information and/or the part information associated with the thermal image data, or is further related to the part information and the analysis result corresponding thereto. Further, the rule of the predetermined processing and the predetermined condition associated with the information on the object information and/or the part information may be used.
The processing device comprises an acquisition part, a processing part and a processing part, wherein the acquisition part is used for acquiring multi-frame thermal image data; the analysis part is used for analyzing the shot object information and/or the part information related to each frame of thermal image data in the multi-frame thermal image data; and the processing part is used for performing specified processing according to specified conditions to obtain a processing result of the multi-frame thermal image data.
The thermal image data of a plurality of frames is generally processed by using specified conditions such as longitudinal (for example, comparison of thermal image data captured at different times), transverse (for example, comparison of thermal image data captured at specified times), and the like. The prescribed conditions may also be set according to various parameters associated with the acquisition of thermal image data by shooting, such as various parameters (e.g., radiance, shooting distance, lens parameters, etc.) of the thermal image device 13 during shooting, environmental conditions (e.g., ambient temperature, humidity, wind speed, etc.), parameters related to the subject (e.g., subject load parameters, current, voltage, rotational speed, etc.), and other external parameters (e.g., information of a device connected to the subject or the thermal image device 13, such as a GPS device, etc.). Further, when the thermal image data is associated with the object information, the predetermined condition may be set according to the object information, for example, a predetermined process such as a longitudinal comparison for the same object, and a predetermined process such as a comparison of analysis results in a longitudinal direction and a transverse direction for thermal image data obtained by shooting the same group (for example, A, B, C phase; for example, the same equipment area; the same group condition including the same object information).
And comparing and analyzing, namely comparing analysis results obtained by appointed multi-frame thermal image data, and obtaining a further accurate comprehensive analysis result according to a comparison result by generally adopting comparison between analysis values. When the position information is adopted for carrying out comparison analysis, the method is more accurate. And if the acquired multi-frame thermal image data is acquired, performing comparative analysis according to the analysis value of the specific part to determine the state property of the thermal image data with the maximum analysis value. The method is generally used for transverse comparison and analysis of thermal image data of the same type of objects; historical comparison of thermal image data of the same shot object; comparative analysis of thermal image data of the same group (e.g., A, B, C phase) of subjects. Obviously, when the same group of conditions is the same object, the same group of objects includes an object thermal image shot by the whole object and an object thermal image shot by the local object according to parts, and the comparison and analysis at this time can select the analysis result with the maximum defect degree from the object thermal image and the analysis result is used as the result of the comparison and analysis of the group, and the image which can present the corresponding thermal image data corresponding to the analysis result; the condition of confusion can be avoided, and the method is suitable for application of query, statistics and the like in a database; for example, in one embodiment, in the case of statistics, when the analysis result of the entire thermal image of the object is "defect", and the analysis result obtained by performing special shooting on the defect part is "critical defect", it should be counted as "critical defect".
Classifying, for example, classifying and sorting the thermal image data (frames) according to the analysis result of the specific part and the set processing rule (classification rule) from the multi-frame thermal image data; and if the acquired multi-frame thermal image data is obtained, classifying the multi-frame thermal image data according to the state properties (normal, defective and dangerous) of the specific part, for example, classifying according to a specific folder.
Statistical processing, for example, performing statistics from the multi-frame thermal image data according to the analysis result of the specific portion and the set processing rule (statistical rule); for example, the obtained thermal image data of multiple frames is counted according to the number or percentage of state properties (normal, defective, and dangerous) of a specific part. For example, the user can obtain statistical data of the analysis result of the joint portion of the subject of a specific apparatus type by selecting the portion information such as "joint" and "apparatus type".
Searching, for example, searching the thermal image data (frames) which are in accordance with the analysis result of the specific part and the set processing rule (searching rule) from the multi-frame thermal image data; and if the acquired multi-frame thermal image data are acquired, performing comparative analysis according to the analysis value of the specific part, and finding out the maximum analysis value and/or the corresponding thermal image data.
