The control unit 9 is an example of a ring temperature acquisition unit for acquiring a ring temperature;
the control section 9 is an example of an analysis section for acquiring analysis data from the obtained thermal image data; the analysis data may be a temperature value obtained by analysis, or may be other values obtained by analysis (for example, an AD value of a pixel, an AD maximum value, a minimum value, an average value, or the like in a region, or may be a ratio, or the like); the analysis data may be obtained based on 1 or more analysis areas (points, lines, areas), and the temperature values may be point temperatures, highest temperatures, lowest temperatures, average temperatures, etc.
The control unit 9 is an example of a compensation control unit, and activates the ring temperature compensation when the condition for the ring temperature compensation is satisfied; if not, the ring temperature compensation is not started; preferably, the control section 9 is an example of a compensation control section for judging whether or not the compensation condition is satisfied based on the analysis data obtained from the analysis; there may be a variety of compensation conditions; the compensation conditions (which may be preprogrammed, for example) are set or selected by the user; or may be default.
The compensation conditions are as follows:
1) Based on pairs ofIdentifying a subject target to confirm whether compensation is to be applied to the subject target;
2) Determining a target of a detected object based on manual work, and compensating;
3) Based on the analysis data before the target compensation of the tested body, whether the target compensation data meets the set value of the compensation condition or not; if one or more of the conditions are smaller than, larger than, equal to, within, and beyond the set value range, determining whether to compensate; the set value is, for example, the ring temperature, and the analysis data before compensation is smaller than the ring temperature, and compensation is performed.
4) When it is determined whether compensation is performed based on the obtained analysis data before compensation, whether the compensation condition set value is met. Preferably, the temperature value before uncompensated can be obtained based on thermal image data analysis, and is used for judging whether compensation is needed; in other examples, it is also possible to determine whether compensation is necessary based on the characteristics of the thermal image AD value; in a preferred example, the identified subject targets may be compensated; whether the obtained analysis data come from the detected target or not can be judged according to algorithms such as image recognition and the like, and if the analysis data are the analysis data of the sky background, compensation is not needed; if the analysis data from the tested body is judged, if the ring temperature compensation condition is met, compensation is carried out. Preferably, the compensation control unit activates the ring temperature compensation when the condition for the ring temperature compensation is satisfied based on the obtained analysis data.
For example, when the temperature obtained by the analysis of the measured object is lower than the ring temperature, the ring temperature compensation is started, for example, the temperature of the measured object can be compensated to be not lower than the ring temperature; so as to avoid the influence caused by the low temperature of the background reflection.
When there are multiple analysis areas (e.g., points, lines, planes), it may be desirable to compensate for the analysis value (e.g., temperature value) of at least one of the analysis areas. The control unit 9 may be a compensation unit for performing compensation processing based on the acquired ring temperature, and may be various;
in one example, when the compensation condition is satisfied, compensation is enabled; the compensation value related to the compensation is obtained based on the ring temperature (can be default or manually set, can be ring temperature or ring temperature x coefficient or ring temperature + -constant such as 1 and other modes); and compensating the analysis data obtained by the thermal image data analysis according to the compensation value.
In one example, when the compensation condition is satisfied, compensation is enabled; the compensation value related to the compensation is obtained based on the ring temperature; and the analysis data are acquired according to the thermal image data and the compensation value. In one example, the compensation process may be performed based on a limit value (including a limit range) without setting the compensation value in advance;
in one example, when the compensation condition is satisfied, compensation is enabled; enabling the compensated analysis data to accord with a limit value; the limiting value is obtained based on the ring temperature.
In one example, during thermal image data analysis, compensation processing is combined to obtain analysis data; enabling the compensated analysis data to accord with a limit value; the limiting value is obtained based on the ring temperature.
The compensated analysis data accords with a limit value, including not less than the limit value, or more than the limit value, or in a limit range or out of the limit range, and the like; for example, it is preferable to make the compensated temperature measurement value not smaller than the limit value or within the limit range. For example, the temperature is set based on the ring temperature, and the ring temperature may be set as a limit value so that the temperature after compensation is not lower than the ring temperature; in other examples, the temperature after compensation may be set to not lower than-2 degrees, for example, by setting the ring temperature to-2 degrees as a limit value. There may be a certain limited range (for example, the ring temperature ±1 degree is used as the limited range), and there may be a plurality of configurations of the limited values; the limit value may be default, for example, or may be user configurable, for example.
When the ring temperature changes, the corresponding compensation value or limit value also changes.
To avoid the heated part of the object to be compensated to the ring temperature, preferably, the user can set a reference body, such as the non-heated part of the object to be compensated to the limit value of the ring temperature; in one example, a portion of the subject that does not generate heat is used as a reference body; then according to the temperature difference between the heating part and the non-heating reference body before compensation, combining the temperature of the reference body after compensation, and adding the temperature to be used as a temperature measurement value after compensation of the heating part; in another example, the obtained compensation value is applied to analysis or compensation of other measured objects to obtain analysis data after compensation of other measured objects.
A reference body setting section for setting an environmental reference body; the compensation part compensates the temperature measured value of the reference body obtained by the thermal image data analysis according to the acquired ring temperature, so that the compensated temperature measured value is equal to a limit value; specific compensation values can then be obtained, which are used for subsequent compensation or analysis; for example, the user determines the reference body in the thermal image, and then compensates the temperature of the reference body to the ring temperature, so that the control part can obtain a compensation value, and the compensation value can be used for analysis of subsequent thermal image data and the like.
In another example, the acquisition part is used for acquiring thermal image data of at least one analysis area; a compensation value acquisition section for acquiring a compensation value; the compensation value is used for compensation or analysis of other analysis areas or for subsequent thermal image data, compensation or analysis of analysis areas. Due to the complexity of the background, in other preferred examples, the frequency of updating the reference body can be set to perform the compensation process; for example, the temperature value of the reference body is compensated to the ring temperature at the previous time and the compensation value is obtained, but at the time of the subsequent photographing, the subsequent reference body cannot be compensated to the ring temperature according to the compensation value, at this time, the compensation of the reference body may be performed again and the compensation value may be obtained again.
When a plurality of differential measured values exist in the measured object, the measured value with the lowest temperature in the measured object can be compensated to be not lower than the ring temperature limit value, and other analysis data can accumulate the temperature difference with the lowest measured value and perform superposition calculation to obtain the compensated measured value; for example, two analysis areas S01/S02 are set for the measured body, the highest temperature value of S01 before compensation is-5 ℃, the highest temperature value of S02 before compensation is 0 ℃, the ring temperature is 20 ℃, and S01 can be compensated to 20 ℃, and S02 can be compensated to 25 ℃.
In general, the highest temperature, the point temperature and the line temperature of the analysis area can be subjected to ring temperature compensation; in other examples, the ring temperature compensation may be performed on analysis data such as the spot temperature, the highest temperature, the lowest temperature, the average temperature, and the like. The compensation is not limited to the compensation of the temperature value, and in other examples, the thermal image AD value data may be compensated to obtain a compensated measurement value.
In one example, the ring temperature compensation device includes:
an acquisition section for acquiring thermal image data; a ring temperature acquisition unit for acquiring a ring temperature;
an analysis unit configured to acquire analysis data from the thermal image data;
a first compensation control section that enables compensation (e.g., a first compensation control process) when the compensation condition is satisfied; compensating the analysis data obtained by the thermal image data analysis, so that the compensated first analysis data accords with a limit value; the limiting value is obtained based on the ring temperature; a compensation value acquisition section for acquiring a compensation value of the first analysis data;
a second compensation control unit that activates compensation when the compensation condition is satisfied; the compensation value related to the compensation is acquired by the compensation value acquisition part; and compensating analysis data obtained by analyzing the obtained thermal image data according to the compensation value.
For example, the subject is provided with two analysis regions S01/S02, the highest temperature value of S01 before compensation is-5 ℃, the highest temperature value of S02 before compensation is 0 ℃, and the ring temperature is 20 ℃. Assuming that S01 is a reference body (for example, the user designates the reference body), the limit value is set to the ring temperature (the ring temperature may also be a coefficient of ring temperature or a fixed value of ring temperature ± such as 1, etc.), S01 may be compensated to 20 degrees, and at this time, the compensation value is 25 degrees; when the compensation is performed on the S02, the highest temperature value of the S02 before the compensation is plus the compensation value, and the temperature after the compensation is 25 degrees.
However, the compensation method is not limited to addition, and in other examples, there may be various algorithms, for example, weighting of the influence of various environmental parameters, and according to different cases, the compensation value may be combined with a coefficient or the like.
In another example, an apparatus for compensating for ambient temperature includes:
an acquisition section for acquiring thermal image data; a ring temperature acquisition unit for acquiring a ring temperature;
a first compensation control unit that, when a compensation condition is satisfied, activates a first compensation process;
the first analysis part is used for acquiring compensated analysis data according to the thermal image data according to the control of the first compensation control part, and the compensated first analysis data accords with a limit value; the limiting value is obtained based on the ring temperature;
a compensation value acquisition section for acquiring a compensation value of the first analysis data;
a second compensation control unit that activates compensation when the compensation condition is satisfied; the compensation value related to the compensation is acquired by the compensation value acquisition part; and compensating analysis data obtained by analyzing the obtained thermal image data according to the compensation value.
Preferably, compensation configuration information can be preset to perform temperature compensation;
in one example, the compensated temperature measurement T1 satisfies t1=h+x×t0;
wherein T0 is the temperature measurement before compensation; h represents a compensation value; x is a compensation coefficient; h=w+x; w is the ring temperature, X is a constant
Preferably, the compensation configuration information is prepared in advance corresponding to different distances and/or different background temperatures, respectively.
The table shown in FIG. 3 represents one example of compensation configuration information at a particular background temperature and/or distance; a table may be included of the relationship between the plurality of temperature values and the compensation coefficient. The meter can be obtained through experiments under low-temperature backgrounds such as black bodies, thermal imagers and the like.
The compensation configuration information may be prepared in advance in the production link, for example, configured by a user on site, and the information configuration device may be configured with a storage medium storing the compensation configuration information; preferably, the information configuration device may be configured with an operation interface for the user to set the compensation configuration information, which may be similar to the form of the table in fig. 3.
Preferably, the control unit 9, the operation unit, the display unit, and the like may constitute a configuration unit for configuring parameters included in the compensation configuration information.
The processing flow will be described below, and in this embodiment, compensation configuration information including that shown in the exemplary list in fig. 3 is stored in advance in the flash memory 8.
The control unit 9 controls the overall operation of the temperature compensation device 12, and the control unit 9 is implemented by, for example, CPU, MPU, SOC, a programmable FPGA, or the like. The flash memory 8 stores therein a program for control and various data used for control of each part. Referring to fig. 4, the control steps are as follows:
step A01, based on the control of the control part 9, shooting to acquire thermal image data;
step A02, analyzing and obtaining a temperature measurement value before compensation; for example, obtaining a temperature of-5 degrees for the wire clamp; this is affected by the low temperature reflection of the background, which is easily confusing to the user;
step A03, if the analysis value is smaller than the limit range, starting ring temperature compensation;
assuming that the ring temperature obtained by the temperature sensing is 20 ℃, limiting the range to be that the measured temperature is not lower than the ring temperature, for example, limiting the value to be the obtained ring temperature; at this time, ring temperature compensation is started;
step a04, obtaining compensated temperature measurements, for example to 20 degrees;
at this time, the measured value displayed in the interface of the thermal imager is 20 degrees.
In addition, the processing and control functions of some or all of the components in the embodiments of the present invention may also be implemented with dedicated circuits or general-purpose processors or programmable FPGAs.
In addition, in the embodiment, the application of the detected body in the power industry is taken as a scene example, and the method is also suitable for being widely applied in various industries of infrared detection.
Obviously, more embodiments are obtained by combining the above working steps differently. Obviously, more embodiments are possible depending on the different combinations of the modes of operation described above.
It is obvious that when the ring temperature compensation device of the present invention is used as a certain component of the ring temperature compensation device 12 with a display control part, the display control part can be omitted, and the present invention is also constituted.
