Description

Technical Field

[0001] The present application relates to the technical field of optoelectronic detection, and particularly to a method for determining radiation increment, a method for determining correction parameters, and an apparatus therefor. Background Art

[0002] An infrared multi-band detector includes a plurality of detection units. Each detection unit may include a filter. Each filter may transmit infrared light in a specified band and block infrared light in other bands. Correspondingly, when using the infrared multi-band detector for detection, the infrared multi-band detector may obtain the radiation signal of the object to be measured in the corresponding specified band through each filter.

[0003] The infrared multi-band detector converts the radiation signal in the specified band corresponding to each filter into an electrical signal, and numerically quantifies the converted electrical signal to obtain the response value corresponding to the specified band corresponding to the filter. The response value represents the radiation intensity of the radiation signal in the specified band corresponding to the filter. Subsequently, the radiation increment of the object to be measured in the specified band corresponding to the filter may be calculated according to the radiation intensity of the radiation signal in the specified band corresponding to the filter. Furthermore, feature analysis may be performed based on the radiation increments of the object to be measured in each band to obtain the corresponding analysis result.

[0004] However, the response rates of different detection units are inconsistent, and the transmittances and bandwidths of different filters are also inconsistent, which will affect the determined radiation increment. For example, the higher the transmittance of a filter, the smaller the attenuation of the radiation signal intensity after passing through the filter, and the higher the radiation intensity of the radiation signal in the specified band transmitted through the filter. Then, the radiation increment of the object to be measured in the specified band corresponding to the filter determined based on the radiation intensity cannot accurately represent the characteristics of the object to be measured in the specified band corresponding to the filter, resulting in a lower accuracy of the analysis result of the subsequent feature analysis.

[0107] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art based on the present application belong to the scope of protection of the present application.

[0108] In the related art, due to the inconsistent transmittance and bandwidth of different filters in a multi-band detector, it will affect the determined radiation increment of the object to be measured in the preset bands corresponding to each filter. Exemplarily, referring to FIGS. 1(a) and 1(b), a rectangle in the figure represents a filter, and A, B, C, and D represent four different filters. The width of each rectangle on the abscissa represents the bandwidth of the corresponding filter, and the height of the rectangle on the ordinate represents the transmittance of the corresponding filter. Denote the bandwidth of a filter as w and the central wavelength as λ, then the preset band corresponding to this filter is [λ-(w / 2), λ+(w / 2)], that is, this filter can transmit radiation signals in the wavelength range of [λ-(w / 2), λ+(w / 2)].

[0109] In an ideal situation, the reference when the multi-band detector receives radiation signals through each filter is the same, that is, when the bandwidths and transmittances of the filters in the multi-band detector are the same, the multi-band detector receives the radiation signals in the corresponding preset bands through each filter. As shown in FIG. 1(a), the bandwidths of the four filters are exactly the same, and the transmittances are also exactly the same. If the radiation intensities of the radiation signals of the object to be measured in the preset bands corresponding to the four filters are the same, in an ideal situation, the radiation increments of the object to be measured in the preset bands corresponding to the four filters A, B, C, and D obtained through the four filters are the same. Denote the radiation increments of the object to be measured in the preset bands corresponding to the four filters A, B, C, and D as a, b, c, and d respectively, then a = b = c = d.

[0110] However, in actual situations, as shown in FIG. 1(b), the bandwidths of different filters are not the same, and the transmittances are also not the same, which results in different references when the multi-band detector receives radiation signals through each filter. The higher the transmittance of a filter, the smaller the attenuation of the radiation signal after passing through the filter, and the higher the radiation intensity of the radiation signal in the preset band transmitted through this filter. The larger the bandwidth of a filter, the larger the wavelength range (i.e., the preset band) of the radiation signal that this filter can transmit, and the higher the radiation intensity of the radiation signal in the preset band transmitted through this filter.

[0111] Correspondingly, if the four filters are in the situation shown in FIG. 1(b), that is, the transmittance of filter D is greater than that of filter A, the transmittance of filter A is greater than that of filter B, and the transmittance of filter B is equal to that of filter C; and, the bandwidth of filter D is greater than that of filter A, the bandwidth of filter A is greater than that of filter B, and the bandwidth of filter B is greater than that of filter C. Correspondingly, when the multi-band detector detects the object to be measured, the radiation increments of the object to be measured in the preset bands corresponding to the four filters A, B, C, and D are different, and d > a > b > c.

[0112] Furthermore, based on the radiation intensities of the object to be measured detected by the multi-band detector at each preset band, the determined radiation increments of the object to be measured at each preset band will cause the determined radiation increments to not accurately represent the characteristics of the object to be measured at each preset band, resulting in a relatively low accuracy of the analysis results of subsequent feature analysis.

[0113] To solve the above problems, an embodiment of the present application provides a method for determining radiation increments. This method is applied to an electronic device, which can be a processor integrated inside the multi-band detector. Alternatively, the electronic device can also be other devices capable of communicating with the multi-band detector, such as terminals, servers, etc.

[0114] The electronic device can, according to the method for determining radiation increments provided by the embodiment of the present application, for each preset band of the multi-band detector, correct the radiation increment corresponding to the preset band according to the increment correction parameter corresponding to the preset band, and obtain the corrected radiation increment corresponding to the preset band, which can improve the accuracy of the determined radiation increment. That is, the corrected radiation increments corresponding to each preset band can represent the characteristics of the object to be measured at each preset band, and further improve the accuracy of the analysis results of feature analysis based on the radiation increments. Subsequently, feature analysis can be performed according to the corrected radiation increments of the object to be measured at each preset band, and the category of the object to be measured can be determined according to the corresponding analysis results. For example, fire point detection, gas detection, etc. can be performed according to the corrected radiation increments of the object to be measured at each preset band.

[0115] See Figure 2 , Figure 2 which is a flowchart of a method for determining radiation increments provided by an embodiment of the present application. The method may include the following steps:

[0116] S201: For each preset band of the multi-band detector, obtain two radiation intensities corresponding to the preset band.

[0117] S202: Calculate the radiation increment between the two radiation intensities corresponding to the preset band.

[0118] S203: Correct the radiation increment corresponding to the preset band according to the increment correction parameter corresponding to the preset band, and obtain the corrected radiation increment corresponding to the preset band.

[0119] Among them, the ratio between the increment correction parameters corresponding to different preset bands remains unchanged.

[0120] Based on the radiation increment determination method provided in the embodiments of the present application, for each preset band of the multi-band detector, based on the increment correction parameter corresponding to the preset band, the radiation increment corresponding to the preset band is corrected to obtain the corrected radiation increment corresponding to the preset band, so that the inconsistency of the response rates of each detection unit, as well as the inconsistency of the transmittance and bandwidth of each filter, on the determined radiation increment can be eliminated, and the accuracy of the determined radiation increment can be improved. Furthermore, the accuracy of the analysis result based on the radiation increment for feature analysis can be improved.

[0121] Regarding steps S201 and S202, the multi-band detector can be an infrared multi-band detector, a visible light multi-band detector, etc. Each preset band of the multi-band detector is: the preset band corresponding to each filter in the multi-band detector. The preset band corresponding to one filter represents: the wavelength range of the optical signal that the filter can transmit.

[0122] In one implementation, for each preset band, the two radiation intensities corresponding to the preset band can include: the radiation intensity of the radiation signal of the preset band obtained by using the multi-band detector to detect the object to be measured. These two radiation intensities are the first test radiation intensity and the second test radiation intensity in the subsequent embodiments.

[0123] For each preset band, the first test radiation intensity corresponding to the preset band can be: the radiation intensity of the radiation signal of the preset band of the object to be measured when using the multi-band detector to detect the object to be measured; the second test radiation intensity corresponding to the preset band can be: the radiation intensity of the radiation signal of the preset band in the background area of the scene where the object to be measured is located when using the multi-band detector to detect the object to be measured at the same time.

[0124] The electronic device calculates the absolute value of the difference between the first test radiation intensity and the second test radiation intensity corresponding to the preset band, and can obtain the radiation increment between the first test radiation intensity and the second test radiation intensity. This radiation increment is the radiation increment of the object to be measured in the preset band, and this radiation increment can reflect the difference between the characteristics of the object to be measured and the characteristics of the background area in the scene where the object to be measured is located.

[0125] Or,

[0126] For each preset band, the first test radiation intensity corresponding to the preset band can be: the radiation intensity of the radiation signal of the preset band in the specified area of the scene where the object to be measured is located at the current moment when using the multi-band detector to detect the object to be measured; the second test radiation intensity corresponding to the preset band can be: the radiation intensity of the radiation signal of the preset band in the specified area at the previous moment when using the multi-band detector to detect the object to be measured.

[0127] The electronic device can calculate the absolute value of the difference between the first test radiation intensity and the second test radiation intensity corresponding to the preset band, and obtain the radiation increment between the first test radiation intensity and the second test radiation intensity. This radiation increment is the radiation increment of the specified area in the preset band, and it can reflect the characteristics of the specified area in the scene where the object to be measured is located. Correspondingly, if this radiation increment is large, it indicates that the radiation intensity of the radiation signal in the preset band in the specified area at the current moment is quite different from the radiation intensity of the radiation signal in the preset band in the specified area at the previous moment, which can indicate that the object to be measured in the specified area has moved.

[0128] In another implementation, for each preset band, the two radiation intensities corresponding to the preset band may include: the reference radiation intensity corresponding to the preset band, and the test radiation intensity (the test radiation intensity can be any one of the first test radiation intensity and the second test radiation intensity). For the specific processing methods of the reference radiation intensity and the test radiation intensity, reference can be made to the relevant introduction in the subsequent embodiments.

[0129] Since the response rates of different detection units in the multi-band detector are inconsistent, and the transmittance and bandwidth of different filters are also inconsistent, it will affect the two radiation intensities corresponding to each preset band, and further affect the determined radiation increment corresponding to each preset band. Then, the radiation increment corresponding to each preset band cannot accurately represent the characteristics of the object to be measured in each preset band.

[0130] For step S203, in order to determine the radiation increment that can accurately represent the characteristics of the object to be measured in each preset band and improve the accuracy of the determined radiation increment, the electronic device can obtain the increment correction parameters corresponding to each preset band of the multi-band detector.

[0131] The ratio between the increment correction parameters corresponding to different preset bands remains unchanged. Correspondingly, the electronic device can obtain the ratio between the increment correction parameters corresponding to each preset band, and by setting the increment correction parameter corresponding to any one of the preset bands, calculate the increment correction parameters corresponding to other preset bands.

[0132] Exemplarily, the multi-band detector includes 4 filters, and these 4 filters correspond to 4 preset bands. The ratio between the increment correction parameters corresponding to these 4 preset bands obtained by the electronic device is: 3:2:1:2. If the increment correction parameter corresponding to the first preset band is set to 6, then the increment correction parameters corresponding to the other 3 preset bands are: 4, 2, and 4 respectively; or, if the increment correction parameter corresponding to the first preset band is set to 9, then the increment correction parameters corresponding to the other 3 preset bands are: 6, 3, and 6 respectively.

[0133] Furthermore, for each preset band, the electronic device may correct the radiation increment corresponding to the preset band based on the increment correction parameter corresponding to the preset band, to obtain the corrected radiation increment corresponding to the preset band, that is, the corrected radiation increment of the object to be measured in the preset band. For example, for each preset band, the electronic device calculates the product of the increment correction parameter corresponding to the preset band and the radiation increment corresponding to the preset band, to obtain the corrected radiation increment corresponding to the preset band.

[0134] Exemplarily, the multi-band detector is a four-band detector. The four-band detector corresponds to 4 preset bands. The first test radiation intensities corresponding to the 4 preset bands are: I11, I12, I13, and I14; the second test radiation intensities corresponding to the 4 preset bands are: I21, I22, I23, and I24. The increment correction parameters corresponding to each preset band are: k1, k2, k3, and k4.

[0135] The electronic device calculates the absolute value of the difference between the first test radiation intensity and the second test radiation intensity corresponding to each preset band, to obtain the radiation increment corresponding to each preset band as: (I21 - I11), (I22 - I12), (I23 - I13), (I24 - I14). The electronic device calculates the product of the radiation increment corresponding to each preset band and the increment correction parameter respectively, to obtain the corrected radiation increment corresponding to each preset band as: k1×(I21 - I11), k2×(I22 - I12), k3×(I23 - I13), k4×(I24 - I14).

[0136] Correspondingly, the influence of the inconsistent response rate of each detection unit and the inconsistent transmittance and bandwidth of each filter on the determined radiation increment can be eliminated. Then the corrected radiation increment can represent the characteristics of the object to be measured in each preset band, that is, the accuracy of the determined radiation increment can be improved. Furthermore, the accuracy of the analysis result based on the radiation increment for feature analysis can be improved.

[0137] In some embodiments, on the basis of Figure 2 referring to Figure 3 , before step S203, the method may further include the following steps:

[0138] S204: Obtain multiple groups of alternative increment correction parameters.

[0139] Wherein, each group of alternative increment correction parameters corresponds to a preset temperature range.

[0140] S205: For each set of alternative incremental correction parameters, if the preset temperature range corresponding to the set of alternative incremental correction parameters includes at least one of the temperatures corresponding to the two radiation intensities, determine the set of alternative incremental correction parameters as the incremental correction parameters corresponding to each preset band.

[0141] The electronic device can obtain multiple different preset temperature ranges. For example, N preset temperatures are selected at equal intervals. For every two adjacent preset temperatures among the N preset temperatures, a preset temperature range with these two preset temperatures as endpoints is determined, and multiple preset temperature ranges can be obtained. For each preset temperature range, the electronic device can obtain a set of alternative incremental correction parameters corresponding to the preset temperature range, and thus multiple sets of alternative incremental correction parameters can be obtained.

[0142] For each set of alternative incremental correction parameters, the ratio between the set of alternative incremental correction parameters is determined based on the ratio of the theoretical radiation increments of the reference object for each preset band within the corresponding preset temperature range and the ratio of the measured radiation increments of the reference object for each preset band when the reference object is detected using a multi-band detector.

[0143] Within the corresponding preset temperature range, the ratio of the theoretical radiation increments of the reference object for each preset band is fixed and unchanging, and the ratio of the measured radiation increments of the reference object for each preset band is also fixed and unchanging. Correspondingly, for each set of alternative incremental correction parameters, within the preset temperature range corresponding to the set of alternative incremental correction parameters, the ratio between the set of alternative incremental correction parameters remains unchanged, and the ratio between the set of alternative incremental correction parameters is different from the ratio between other sets of alternative incremental correction parameters. That is, within one preset temperature range, the ratio of the alternative incremental correction parameters corresponding to each preset band remains unchanged, and within different preset temperature ranges, the ratio of the alternative incremental correction parameters corresponding to each preset band is different.

[0144] For each preset band, the temperatures corresponding to the two radiation intensities of the preset band are: the temperatures when generating the two radiation intensities of the preset band.

[0145] For example, the two radiation intensities include: the first measured radiation intensity of the radiation signal of the object to be measured in the preset band and the second measured radiation intensity of the radiation signal of the background area in the scene where the object to be measured is located when using a multi-band detector to detect the object to be measured at the same time. Correspondingly, the temperatures corresponding to the first measured radiation intensity and the second measured radiation intensity are the temperature of the scene where the object to be measured is located. Since the first measured radiation intensity and the second measured radiation intensity are obtained by using a multi-band detector to detect the object to be measured at the same time, the temperatures corresponding to the first measured radiation intensity and the second measured radiation intensity are the same.

[0146] The two radiation intensities include: when using a multi-band detector to detect a to-be-detected object at different times, a first test radiation intensity and a second test radiation intensity of a specified area in the scene where the to-be-detected object is located. Correspondingly, the temperature corresponding to the first test radiation intensity is the temperature of the specified area in the scene where the to-be-detected object is located at the current moment, and the temperature corresponding to the second test radiation intensity is the temperature of the specified area in the scene where the to-be-detected object was located at the previous moment. Therefore, the temperatures corresponding to the first test radiation intensity and the second test radiation intensity may be different.

[0147] Since the temperature of the to-be-detected object will also affect the radiation intensity of the radiation signal of the to-be-detected object in each preset band, and further affect the radiation increment of the to-be-detected object in each preset band. In order to reduce the influence of temperature on the radiation increment of the to-be-detected object in each preset band, for each group of alternative increment correction parameters, if the preset temperature range corresponding to the group of alternative increment correction parameters includes at least one of the temperatures corresponding to the two radiation intensities, it indicates that the preset temperature range when generating the group of alternative increment correction parameters is relatively close to the temperature when generating the two radiation intensities corresponding to the preset band. The electronic device can determine the group of alternative increment correction parameters as the increment correction parameters corresponding to each preset band. Subsequently, when performing correction based on the increment correction parameters, the influence of the temperature of the to-be-detected object on the radiation intensity of the radiation signal can be reduced, and the accuracy of the determined corrected radiation increment corresponding to each preset band can be further improved.

[0148] In some embodiments, for each preset temperature range, within the preset temperature range, the ratio of the theoretical radiation increments of the reference object for each preset band is determined based on the theoretical radiation intensities of the reference object for each preset band within the preset temperature range; within the preset temperature range, the ratio of the test radiation increments of the reference object for each preset band is determined based on the test radiation intensities of the reference object for each preset band within the preset temperature range.

[0149] For each preset temperature range, the electronic device can calculate a group of alternative increment correction parameters corresponding to the preset temperature range based on the theoretical radiation intensity and the test radiation intensity of the reference object for each preset band within the preset temperature range in the following manner. Correspondingly, refer to Figure 4 , Figure 4 is a flowchart of a method for determining correction parameters provided by an embodiment of the present application. The method may include the following steps:

[0150] S401: For each preset band of the multi-band detector, calculate the radiation intensity of the radiation signal with the central wavelength of the preset band emitted by the reference object at two preset temperatures respectively, as the two theoretical radiation intensities corresponding to the preset band.

[0151] S402: Calculate the radiation increment between the two theoretical radiation intensities corresponding to the preset band to obtain the theoretical radiation increment of the reference object for the preset band.

[0152] S403: Calculate the ratio of the respective theoretical increments of the reference object for each preset band as the first ratio.

[0153] S404: For each preset band, obtain the radiation intensities of the radiation signals of the reference object in the preset band when the reference object is detected by the multi-band detector at the two preset temperatures, respectively, as the two measured radiation intensities corresponding to the preset band.

[0154] S405: Calculate the radiation increment between the two measured radiation intensities corresponding to the preset band to obtain the measured radiation increment of the reference object for the preset band.

[0155] S406: Calculate the ratio of the respective measured radiation increments of the reference object for each preset band as the second ratio.

[0156] S407: Calculate the correction parameter for correcting the second ratio to the first ratio to obtain the increment correction parameter corresponding to the preset temperature range with the two preset temperatures as endpoints.

[0157] Based on the correction parameter determination method provided in the embodiments of the present application, the increment correction parameter can be determined based on the respective theoretical radiation increments and respective measured radiation increments of the reference object for each preset band. The calculated increment correction parameter is used to correct the radiation increment corresponding to each preset band. The respective theoretical radiation increments of the reference object for each preset band can represent: the radiation increment of the reference object in each preset band when the influence of the response rate of each detection unit is not considered and the influence of the transmittance and bandwidth of the filter is not considered. The respective measured radiation increments of the reference object for each preset band represent: the radiation increment of the reference object in each preset band under the influence of the response rate of each detection unit and under the influence of the transmittance and bandwidth of each filter. Subsequently, based on the increment correction parameter corresponding to each preset band, the radiation increment corresponding to each preset band is corrected, so that the influence of the inconsistent response rate of each detection unit and the inconsistent radiation increment of the transmittance and bandwidth of each filter can be eliminated, the accuracy of the determined radiation increment can be improved, and further the accuracy of the analysis result based on the radiation increment for feature analysis can be improved.

[0158] For step S401, when the reference object is a blackbody, for each preset band, the electronic device can obtain the central wavelength of the preset band, and based on the Planck blackbody radiation formula and the central wavelength of the preset band, calculate the radiation intensities of the radiation signals with the wavelength of the central wavelength of the preset band emitted by the blackbody at two preset temperatures respectively, so as to obtain two theoretical radiation intensities corresponding to the preset band. The Planck blackbody radiation formula is as follows:

[0159]

[0160] I represents the theoretical radiation intensity of the radiation signal with the wavelength of λ emitted by the blackbody when the temperature of the blackbody is T; λ represents the wavelength of the radiation signal emitted by the blackbody; h represents the Planck constant; c represents the speed of light; e represents the natural constant; k represents the Boltzmann constant; T represents the temperature of the blackbody.

[0161] For each preset band, the electronic device takes the central wavelength of the preset band as λ in the above formula (1), and takes one preset temperature as T in the above formula (1), and can calculate the theoretical radiation intensity of the radiation signal with the wavelength of the central wavelength of the preset band emitted by the blackbody at the preset temperature.

[0162] For each preset band, the theoretical radiation intensity of the reference object for the preset band represents: when the influence of the response rate of each detection unit is not considered, and the influence of the transmittance and bandwidth of the filter is not considered, the radiation intensity of the radiation signal of the reference object in the preset band.

[0163] For steps S402 and S403, the electronic device calculates the absolute value of the difference between the two theoretical radiation intensities corresponding to the preset band, obtains the radiation increment between the two theoretical radiation intensities corresponding to the preset band, and takes it as the theoretical radiation increment of the reference object for the preset band. Furthermore, the electronic device calculates the ratio of the theoretical radiation change amounts of the reference object for each preset band as the first ratio.

[0164] Exemplarily, see Figure 5 , Figure 5 is a comparison chart of the theoretical radiation intensities corresponding to each preset band at different preset temperatures. The theoretical radiation intensities corresponding to each preset band at different preset temperatures include: the theoretical radiation intensities of the reference object for each preset band at two preset temperatures. The lower preset temperature of the two preset temperatures is denoted as T low , and the higher preset temperature is denoted as T high . The multi-band detector is a four-band detector, and the four-band detector includes 4 filters. The preset bands corresponding to the 4 filters are: band 1, band 2, band 3, and band 4.

[0165] Figure 5The curve with dots represents T high The corresponding theoretical radiation intensity curve, and the curve with triangles represents T low The corresponding theoretical radiation intensity curve. T low The corresponding theoretical radiation intensity curve is: when the temperature of the reference object is T low The theoretical radiation intensity curve of the reference object for the 4 preset bands. T high The corresponding theoretical radiation intensity curve is: when the temperature of the reference object is T high The theoretical radiation intensity curve of the reference object for the 4 preset bands.

[0166] For each preset band, a straight line between a point on the theoretical radiation intensity curve corresponding to the preset band at T high and a point on the theoretical radiation intensity curve corresponding to the preset band at T low represents the theoretical radiation increment of the reference object for the preset band. Specifically, the theoretical radiation increment of the reference object for band 1 is α1, the theoretical radiation increment of the reference object for band 2 is α2, the theoretical radiation increment of the reference object for band 3 is α3, and the theoretical radiation increment of the reference object for band 4 is α4.

[0167] Correspondingly, the first ratio of the theoretical radiation increments of the reference object for each preset band is: α1∶α2∶α3∶α4.

[0168] For step S404, for each preset band, when the electronic device uses the multi-band detector to detect the reference object at two preset temperatures respectively, the radiation intensity of the radiation signal obtained through the filter corresponding to the preset band is used to obtain the radiation intensity of the radiation signal of the reference object in the preset band, as the two test radiation intensities corresponding to the preset band. Correspondingly, the test radiation intensities of the reference object for each preset band represent: under the influence of the response rate of each detection unit, and under the influence of the transmittance and bandwidth of each filter, the radiation intensity of the radiation signal of the reference object in each preset band.

[0169] For step S405 and step S406, the electronic device calculates the absolute value of the difference between the two test radiation intensities corresponding to the preset band, and obtains the radiation increment between the two test radiation intensities corresponding to the preset band, as the test radiation increment of the reference object for the preset band. Furthermore, the electronic device calculates the ratio of the test radiation increments of the reference object for each preset band, as the second ratio.

[0170] Exemplarily, refer to Figure 6 , Figure 6It is a comparison graph of the test radiation intensities corresponding to each preset band at different preset temperatures. The test radiation intensities corresponding to each preset band at different preset temperatures include: the test radiation intensities of the reference object for each preset band at two preset temperatures. The lower of the two preset temperatures is denoted as T low , and the higher preset temperature is denoted as T high . The multi-band detector is a four-band detector. The four-band detector includes 4 filters. The preset bands corresponding to the 4 filters are respectively: Band 1, Band 2, Band 3, and Band 4.

[0171] Figure 6 The dotted line corresponding to each preset band in high indicates: when the temperature of the reference object is T Figure 6 , the test radiation intensity of the reference object for this preset band. low The triangular line corresponding to each preset band in Figure 6 indicates: when the temperature of the reference object is T high , the test radiation intensity of the reference object for this preset band. The test radiation intensity of the reference object for a preset band is: the gray scale value corresponding to the radiation signal of the reference object in this preset band. low The fact that the dotted lines corresponding to each preset band in

[0172] Figure 6 are not on the same horizontal line indicates: when the temperature of the reference object is T high , the test radiation intensities of the reference object for each preset band are different; the fact that the triangular lines corresponding to each preset band are not on the same horizontal line indicates: when the temperature of the reference object is T low , the test radiation intensities of the reference object for each preset band are also different.

[0173] Correspondingly, the second ratio of the test radiation increments of the reference object for each preset band is: β1∶β2∶β3∶β4.

[0174] For step S407, the electronic device calculates the correction parameter for correcting the second ratio to the first ratio, and obtains the increment correction parameter corresponding to the preset temperature range with these two preset temperatures as endpoints.

[0175] For Figure 5 and Figure 6In the illustrated embodiment, in an ideal situation, the response rates of the respective detection units are consistent, and the transmittance and bandwidth of each filter are exactly the same. Then, the first ratio of each test radiation increment is the same as the second ratio of the theoretical radiation increment, that is, the test radiation increment and the theoretical radiation increment satisfy the following formula (2).

[0176] α1∶α2∶α3∶α4=β1∶β2∶β3∶β4 (2)

[0177] However, in actual situations, the response rates of the respective detection units are not consistent, and the transmittance and bandwidth of each filter may also be inconsistent, resulting in a difference between the test radiation increment and the theoretical radiation increment. Therefore, as shown in the following formula (3), the increment correction parameters k1 to k4 are introduced to correct the test radiation increment, so that the ratio of each test radiation increment is the same as the ratio of each theoretical radiation increment.

[0178] α1∶α2∶α3∶α4=(k1×β1)∶(k2×β2)∶(k3×β3)∶(k4×β4) (3)

[0179] Based on the above formula (3), the ratio between the increment correction parameters k1 to k4 can be calculated. Correspondingly, if any one of the increment correction parameters from k1 to k4 is set to a fixed value (for example, 1), a set of alternative increment correction parameters corresponding to the preset temperature range can be obtained. Correspondingly, each increment correction parameter can represent the conversion relationship between the ratio of the theoretical radiation increments of the reference object for multiple filters and the ratio of each test radiation increment.

[0180] In some embodiments, the electronic device can obtain multiple different preset temperature ranges. For each preset temperature range, a set of alternative increment correction parameters corresponding to the preset temperature range is determined in the above manner, and then multiple sets of alternative increment correction parameters can be obtained. Subsequently, after the electronic device obtains multiple sets of alternative increment correction parameters corresponding to each preset temperature range, based on the temperature corresponding to each preset band, the increment correction parameter corresponding to each preset band can be determined from each set of alternative increment correction parameters.

[0181] In some embodiments, after step S203, the method may further include the following steps: determining the pseudo-color image information of the object to be measured based on the corrected radiation increments corresponding to each preset band.

[0182] The electronic device determines the pseudo-color image information of the object to be measured according to the corrected radiation increment of the object to be measured in each preset band. For example, based on the magnitudes of the corrected radiation increments of different regions in the object to be measured in each preset band, the colors of different regions in the object to be measured in the pseudo-color image are determined. Subsequently, the electronic device can display the pseudo-color image of the object to be measured according to the pseudo-color image information of the object to be measured for the user to view. Correspondingly, the user can determine the category of the object to be measured according to the pseudo-color image of the object to be measured.

[0183] See Figure 7 , Figure 7 is a flowchart of an increment determination method provided by an embodiment of the present application. The method may include the following steps:

[0184] S701: For each preset band of the multi-band detector, obtain the reference radiation intensity, the first test radiation intensity, and the second test radiation intensity corresponding to the preset band.

[0185] S702: Calculate the radiation increment between the first test radiation intensity and the reference radiation intensity as the first radiation increment, and calculate the radiation increment between the second test radiation intensity and the reference radiation intensity as the second radiation increment.

[0186] S703: According to the increment correction parameter corresponding to the preset band, correct the first radiation increment and the second radiation increment respectively to obtain a first correction result and a second correction result.

[0187] Among them, the ratio between the increment correction parameters corresponding to different preset bands remains unchanged.

[0188] S704: Calculate the difference between the first correction result and the second correction result to obtain the corrected radiation increment between the first test radiation intensity and the second test radiation intensity corresponding to the preset band.

[0189] Based on the radiation increment determination method provided by the embodiment of the present application, for each preset band of the multi-band detector, based on the increment correction parameter corresponding to the preset band, correct the radiation increment corresponding to the preset band to obtain the corrected radiation increment corresponding to the preset band, which can eliminate the influence of the inconsistent response rates of each detection unit and the inconsistent transmittance and bandwidth of each filter on the determined radiation increment, improve the accuracy of the determined radiation increment, and further improve the accuracy of the analysis result based on the radiation increment for feature analysis.

[0190] Regarding steps S701 and S702, for each preset band of the multi-band detector, the reference radiation intensity corresponding to the preset band is: when the multi-band detector detects a reference object, the radiation intensity of the radiation signal of the reference object in the preset band.

[0191] The first test radiation intensity and the second test radiation intensity corresponding to the preset band are: the radiation intensity of the radiation signal of the preset band obtained by detecting the object to be measured using a multi-band detector. The first test radiation intensity and the second test radiation intensity may refer to the relevant introductions in the foregoing embodiments.

[0192] Then, the electronic device can calculate the absolute value of the difference between the first test radiation intensity and the reference radiation intensity to obtain the radiation increment (i.e., the first radiation increment) between the first test radiation intensity and the reference radiation intensity. Moreover, the electronic device can also calculate the absolute value of the difference between the second test radiation intensity and the reference radiation intensity to obtain the radiation increment (i.e., the second radiation increment) between the second test radiation intensity and the reference radiation intensity.

[0193] The first test radiation intensity is: the radiation intensity of the radiation signal of the preset band of the object to be measured when using a multi-band detector to detect the object to be measured; the second test radiation intensity is: the radiation intensity of the radiation signal of the preset band of the background area in the scene where the object to be measured is located when using a multi-band detector to detect the object to be measured at the same time. Correspondingly, the first radiation increment represents: the difference between the radiation intensity of the radiation signal of the preset band of the reference object and the radiation intensity of the radiation signal of the preset band of the object to be measured; the second radiation increment represents: the difference between the radiation intensity of the radiation signal of the preset band of the reference object and the radiation intensity of the radiation signal of the preset band of the background area in the scene where the object to be measured is located.

[0194] The first test radiation intensity is: the radiation intensity of the radiation signal of the preset band of the specified area in the scene where the object to be measured is located at the current moment when using a multi-band detector to detect the object to be measured; the second test radiation intensity may be: the radiation intensity of the radiation signal of the preset band of the specified area at the previous moment when using a multi-band detector to detect the object to be measured. Correspondingly, the first radiation increment represents: the difference between the radiation intensity of the radiation signal of the preset band of the reference object and the radiation intensity of the radiation signal of the preset band of the specified area in the scene where the object to be measured is located at the current moment; the second radiation increment represents: the difference between the radiation intensity of the radiation signal of the preset band of the reference object and the radiation intensity of the radiation signal of the preset band of the specified area in the scene where the object to be measured is located at the previous moment.

[0195] Regarding step S703, in order to determine the radiation increment that can accurately represent the characteristics of the object to be measured in each preset band and improve the accuracy of the determined radiation increment, the electronic device can obtain each increment correction parameter corresponding to each preset band of the multi-band detector. The ratio between the increment correction parameters corresponding to different preset bands remains unchanged.

[0196] In some embodiments, on the basis of Figure 7 refer toFigure 8 , before step S703, the method may further include the following steps:

[0197] S705: Obtain multiple groups of alternative incremental correction parameters.

[0198] Wherein, each group of alternative incremental correction parameters corresponds to a preset temperature range.

[0199] S706: For each group of alternative incremental correction parameters, if the preset temperature range corresponding to the group of alternative incremental correction parameters includes at least one of the temperatures corresponding to the first test radiation intensity and the second test radiation intensity, determine that the group of alternative incremental correction parameters is the incremental correction parameter corresponding to each preset band.

[0200] In some embodiments, for each group of alternative incremental correction parameters, within the preset temperature range corresponding to the group of alternative incremental correction parameters, the ratio between the group of alternative incremental correction parameters remains unchanged, and the ratio between the group of alternative incremental correction parameters is different from the ratio between other groups of alternative incremental correction parameters.

[0201] In some embodiments, the ratio between each group of alternative incremental correction parameters is determined based on the ratio of the theoretical radiation increments of the reference object for each preset band within the corresponding preset temperature range, and the ratio of the measured radiation increments of the reference object for each preset band when the reference object is detected by a multi-band detector.

[0202] The manner in which the electronic device obtains the incremental correction parameters corresponding to each preset band may refer to the relevant introduction in the foregoing embodiments.

[0203] Then, for each preset band, the electronic device may calculate a first correction result and a second correction result corresponding to the preset band based on the incremental correction parameter corresponding to the preset band.

[0204] The first test radiation intensity is: the radiation intensity of the radiation signal of the object to be measured in the preset band when the object to be measured is detected by a multi-band detector; the second test radiation intensity is: the radiation intensity of the radiation signal of the background region in the scene where the object to be measured is located in the preset band during the same detection of the object to be measured by the multi-band detector. Correspondingly, the first correction result represents: the corrected radiation intensity of the radiation signal of the object to be measured in the preset band; the second correction result represents: the corrected radiation intensity of the radiation signal of the background region in the scene where the object to be measured is located in the preset band.

[0205] The first measured radiation intensity is the radiation intensity of the radiation signal in the specified band in the scene where the object to be measured is located at the current moment when using a multi-band detector to detect the object to be measured; the second measured radiation intensity is the radiation intensity of the radiation signal in the specified band in the specified area at the previous moment when using a multi-band detector to detect the object to be measured. Correspondingly, the first correction result represents the corrected radiation intensity of the radiation signal in the specified band in the scene where the object to be measured is located at the current moment; the second correction result represents the corrected radiation intensity of the radiation signal in the specified band in the scene where the object to be measured is located at the previous moment.

[0206] In some embodiments, on the basis of Figure 7 , referring to Figure 9 , step S703 may include the following steps:

[0207] S7031: Correct the reference radiation intensity according to the intensity correction parameter corresponding to the preset band to obtain the corrected reference radiation intensity corresponding to the preset band.

[0208] S7032: Correct the first radiation increment according to the increment correction parameter corresponding to the preset band, and calculate the sum value of the corrected first radiation increment and the corrected reference radiation intensity to obtain the first correction result.

[0209] S7033: Correct the second radiation increment according to the increment correction parameter corresponding to the preset band, and calculate the sum value of the corrected second radiation increment and the corrected reference radiation intensity to obtain the second correction result.

[0210] In some embodiments, the ratio between the intensity correction parameters corresponding to each preset band is determined based on the ratio of the theoretical radiation intensities of the reference object for each preset band and the ratio of the measured radiation intensities of the reference object for each preset band when using a multi-band detector to detect the reference object. The manner in which the electronic device obtains the theoretical radiation intensity and the measured radiation intensity of the reference object for each preset band may refer to the relevant introduction in the foregoing embodiments.

[0211] The electronic device calculates the ratio of the theoretical radiation intensities of the reference object for each preset band (which may be referred to as the third ratio), and calculates the ratio of the measured radiation intensities of the reference object for each preset band (which may be referred to as the fourth ratio). Furthermore, the electronic device calculates the correction parameter for correcting the fourth ratio to the third ratio to obtain the intensity correction parameter corresponding to each preset band.

[0212] For example, the multi-band detector is a four-band detector. The four-band detector includes 4 filters. The 4 preset bands corresponding to the 4 filters. The theoretical radiation intensities of the reference object for each preset band are denoted as: a1, a2, a3, a4. The measured radiation intensities of the reference object for each preset band are denoted as: b1, b2, b3, b4. In an ideal situation, the response rates of each detection unit in the multi-band detector are consistent, and the transmittance and bandwidth of each filter are exactly the same. Then the measured radiation intensity of the reference object for each preset band is consistent with the theoretical radiation intensity. Then the ratio of the theoretical radiation intensities of the reference object for each preset band is the same as the ratio of the measured radiation intensities of the reference object for each preset band. Correspondingly, each measured radiation intensity and each theoretical radiation intensity satisfy the following formula (4).

[0213] a1∶a2∶a3∶a4=b1∶b2∶b3∶b4 (4)

[0214] However, in actual situations, the response rates of each detection unit in the multi-band detector are not consistent, and the transmittance and bandwidth of each filter are also not the same, resulting in a difference between each measured radiation intensity and each theoretical radiation intensity. Therefore, intensity correction parameters m1 to m4 are introduced to correct the measured radiation intensity, so that the ratio of each measured radiation intensity is the same as the ratio of each theoretical radiation intensity, as shown in the following formula (5):

[0215] a1∶a2∶a3∶a4=(m1+b1)∶(m2+b2)∶(m3+b3)∶(m4+b4) (5)

[0216] Based on the above formula (5), the proportional relationship between the intensity correction parameters m1 to m4 can be calculated. If any one of the intensity correction parameters m1 to m4 is set to a fixed value (for example, 0), then the other intensity correction parameters can be obtained, and thus the intensity correction parameters corresponding to each preset band can be obtained. Correspondingly, each intensity correction parameter can represent the conversion relationship between the ratio of the theoretical radiation intensities of the reference object for multiple filters and the ratio of the measured radiation intensities.

[0217] For each preset band, the electronic device can correct the reference radiation intensity according to the intensity correction parameter corresponding to the preset band. For example, the electronic device calculates the sum of the intensity correction parameter corresponding to the preset band and the reference radiation intensity to obtain the corrected reference radiation intensity corresponding to the preset band.

[0218] The electronic device corrects the first radiation increment according to the increment correction parameter corresponding to the preset band to obtain the corrected first radiation increment. For example, the electronic device calculates the product of the increment correction parameter corresponding to the preset band and the first radiation increment to obtain the corrected first radiation increment. Then, the electronic device calculates the sum of the corrected first radiation increment and the corrected reference radiation intensity corresponding to the preset band to obtain the first correction result.

[0219] Exemplarily, for each preset band, the electronic device calculates the first correction result corresponding to the preset band based on the increment correction parameter, intensity correction parameter corresponding to the preset band, and the following formula (6).

[0220] Ai=(mi+bi)+ki×(I1i-bi) (6)

[0221] Ai represents the first correction result corresponding to the i-th preset band; mi represents the intensity correction parameter corresponding to the i-th preset band; bi represents the reference radiation intensity corresponding to the i-th preset band, that is, when using a multi-band detector to detect a reference object, the radiation intensity of the radiation signal of the reference object in the i-th preset band; (mi + bi) represents the corrected reference radiation intensity corresponding to the i-th preset band; ki represents the increment correction parameter corresponding to the i-th preset band; I1i represents the first test radiation intensity corresponding to the i-th preset band; (I1i - bi) represents the first radiation increment corresponding to the i-th preset band.

[0222] For each preset band, the electronic device can also correct the second radiation increment according to the increment correction parameter corresponding to the preset band to obtain the corrected second radiation increment. For example, the electronic device calculates the product of the increment correction parameter corresponding to the preset band and the second radiation increment to obtain the corrected second radiation increment. Then, the electronic device calculates the sum of the corrected second radiation increment and the corrected reference radiation intensity corresponding to the preset band to obtain the second correction result.

[0223] Based on the above processing, the first correction result and the second correction result corresponding to each preset band can be obtained, that is, the corrected radiation intensity of the radiation signal of the object to be measured in each preset band can be obtained. Subsequently, feature analysis can be performed based on the corrected radiation intensity of the radiation signal of the object to be measured in each preset band to improve the accuracy of the feature analysis result.

[0224] For step S704, for each preset band, the electronic device calculates the difference between the first correction result and the second correction result corresponding to the preset band to obtain the corrected radiation increment between the first test radiation intensity and the second test radiation intensity corresponding to the preset band.

[0225] Based on the above processing, the electronic device calculates the first correction result and the second correction result corresponding to each preset band, then the ratio of the test radiation intensities corresponding to each preset band can be adjusted to be the same as the ratio of the theoretical radiation intensities, that is, the test radiation intensities corresponding to each preset band can be made to maintain the same proportional relationship with the theoretical radiation intensities, so that the inconsistent response rates of each detection unit and the inconsistent transmittance and bandwidth of each filter can be eliminated from affecting the test radiation intensities corresponding to each preset band. Furthermore, the electronic device calculates the difference between the first correction result and the second correction result corresponding to each preset band to obtain the corrected radiation increment corresponding to each preset band, so that the inconsistent response rates of each detection unit and the inconsistent transmittance and bandwidth of each filter can be eliminated from affecting the determined radiation increment, and the corrected radiation increment corresponding to each preset band can then represent the characteristics of the object to be measured in each preset band.

[0226] Exemplarily, the reference radiation intensities corresponding to each preset band are denoted as: b1, b2, b3, b4. The multi-band detector is a four-band detector, and the four-band detector includes 4 filters. These 4 filters correspond to 4 preset bands. The first test radiation intensities corresponding to these 4 preset bands are respectively: I11, I12, I13, and I14; the second test radiation intensities corresponding to these 4 preset bands are respectively: I21, I22, I23, and I24. The increment correction parameters corresponding to each preset band are: k1, k2, k3, and k4. The intensity correction parameters corresponding to each preset band are: m1, m2, m3, and m4.

[0227] The electronic device calculates the first correction results corresponding to each preset band in the above manner as follows: (m1 + b1) + k1×(I11 - b1), (m2 + b2) + k2×(I12 - b2), (m3 + b3) + k3×(I13 - b3), (m4 + b4) + k4×(I14 - b4). The electronic device calculates the second correction results corresponding to each preset band in the above manner as follows: (m1 + b1) + k1×(I21 - b1), (m2 + b2) + k2×(I22 - b2), (m3 + b3) + k3×(I23 - b3), (m4 + b4) + k4×(I24 - b4).

[0228] The electronic device calculates the difference between the first correction result and the second correction result corresponding to each preset band respectively, and obtains the corrected radiation increment of the object to be measured in each preset band as follows:

[0229] [(m1 + b1) + k1×(I21 - b1)] - [(m1 + b1) + k1×(I11 - b1)]

[0230] [(m2 + b2) + k2×(I22 - b2)] - [(m2 + b2) + k2×(I12 - b2)]

[0231] [(m3 + b3) + k3×(I23 - b3)] - [(m3 + b3) + k3×(I13 - b3)]

[0232] [(m4 + b4) + k4×(I24 - b4)] - [(m4 + b4) + k4×(I14 - b4)]

[0233] In some embodiments, after step S704, the method may further include the following steps: determining pseudo-color image information of the object to be measured based on the corrected radiation increment corresponding to each preset band.

[0234] The manner in which the electronic device determines the pseudo-color image information of the object to be measured based on the corrected radiation increment corresponding to each preset band may refer to the relevant descriptions in the foregoing embodiments.

[0235] In some embodiments, after step S703, the method may further include the following steps: determining pseudo-color image information of the object to be measured based on the first correction result and the second correction result corresponding to each preset band.

[0236] The first correction result and the second correction result corresponding to each preset band indicate: the radiation intensity after correction of the radiation signal of the object to be measured in each preset band. The electronic device determines the pseudo-color image information of the object to be measured according to the radiation intensity after correction of the radiation signal in each preset band. For example, based on the magnitude of the radiation intensity after correction of the radiation signal in each preset band of different regions in the object to be measured, the color of different regions in the object to be measured in the pseudo-color image is determined. Subsequently, the electronic device may display the pseudo-color image of the object to be measured according to the pseudo-color image information of the object to be measured for the user to view. Correspondingly, the user may determine the category of the object to be measured according to the pseudo-color image of the object to be measured.
