[0056] Before describing the embodiments of the present application in detail, some nouns and terms involved in the embodiments of the present application are first described. The nouns and terms involved in the embodiments of the present application are subject to the following interpretations:

[0057] MEMS stands for micro-electromechanical systems, specifically high-tech devices that are a few millimeters or smaller in size.

[0058] Electrostatic force drive is a driving method based on Coulomb force, which is mainly used to accurately control the movement of structures in micro-electromechanical systems (MEMS). For example, in the MEMS-based FP (Fabry-Perot) interferometer cavity, the distance between two parallel plates is adjusted by electrostatic force drive to achieve wavelength selection. It controls the distance between the plates by applying a voltage between two conductive plates to generate an electrostatic force. This electrostatic force is generated by the attraction (Coulomb force) between the two charged plates. When a voltage is applied between two parallel plates, these plates form a capacitor. According to the characteristics of the capacitor, the electrostatic force F between the two plates can be expressed by the following formula:

[0059]

[0060] In the formula, ∈ represents the dielectric constant of the medium between the plates; A represents the effective area of ​​the plates; V represents the applied voltage; and d represents the distance between the plates.

[0061] In related technologies, hyperspectral cameras control the selection of light by controlling the distance (cavity distance) between two plates in MEMS. In hardware circuits, one plate is usually fixed and the other is adjustable; four voltage points are placed at the edge of the fixed plate (the position is not restricted), and then the voltage of these four points is controlled by electrostatic force to control the cavity distance, thereby obtaining a spectral image of a certain wavelength. At present, the voltage values ​​of the four points are gradually explored through experimental data. If a camera wants to provide spectral images of multiple wavelengths, it is necessary to repeat the experiment many times to find the voltage group corresponding to the wavelength. This processing method has a large workload and can only provide users with limited spectral images corresponding to specified wavelengths.

[0062] In view of this, the embodiments of the present application provide a hyperspectral camera band adjustment method and device, electronic device and storage medium. The present application obtains a target wavelength, at least two adjacent wavelengths to be selected of the target wavelength, and several adjacent voltages to be selected corresponding to the adjacent wavelengths to be selected, and then calculates several target voltages according to the target wavelength, the adjacent wavelengths to be selected and the adjacent voltages to be selected, and then sets the control voltage of the hyperspectral camera according to the target voltage, and then controls the output band of the hyperspectral camera according to the control voltage to control the hyperspectral camera to output a spectral image corresponding to the target wavelength, thereby eliminating the need to repeat experiments multiple times to determine the target voltage corresponding to the target wavelength, and can provide users with spectral images corresponding to multiple wavelengths and effectively reduce the workload.

[0063] The hyperspectral camera band adjustment method provided in the embodiment of the present application relates to the field of camera data processing technology. The hyperspectral camera band adjustment method provided in the embodiment of the present application can be applied to a terminal, can also be applied to a server, and can also be software running in a terminal or a server. In some embodiments, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, and a car terminal, etc., but is not limited to this; the server side can be configured as an independent physical server, or it can be configured as a server cluster or distributed system composed of multiple physical servers, and can also be configured as a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The server can also be a node server in a blockchain network; the software can be an application that implements the hyperspectral camera band adjustment method, etc., but is not limited to the above forms.

[0064] The present application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules.

In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0065] Figure 1 is an optional flow chart of the hyperspectral camera band adjustment method provided in the embodiment of the present application. Figure 1 The method may include but is not limited to steps S110 to S150:

[0066] Step S110, obtaining a target wavelength;

[0067] Step S120, obtaining at least two adjacent wavelengths to be selected corresponding to the target wavelength, and a plurality of adjacent voltages to be selected corresponding to the adjacent wavelengths to be selected;

[0068] Step S130, calculating and obtaining a plurality of target voltages according to the target wavelength, the adjacent wavelength to be selected and the adjacent voltage to be selected;

[0069] Step S140, setting the control voltage of the hyperspectral camera according to the target voltage;

[0070] Step S150: controlling the output band of the hyperspectral camera according to the control voltage to control the hyperspectral camera to output a spectral image corresponding to the target wavelength.

[0071] In the embodiment of the present application, at least two adjacent wavelengths to be selected corresponding to the target wavelength and several adjacent voltages to be selected corresponding to the adjacent wavelengths to be selected can be obtained by experimental means. Since the number of adjacent wavelengths to be selected and adjacent voltages to be selected in the present application is limited, the experimental workload in the experimental method is not high, and the present application obtains adjacent information by experimental means, thereby effectively improving the accuracy of the target voltage calculation.

[0072] In the embodiment of the present application, the process of calculating a plurality of target voltages according to the target wavelength, the adjacent wavelength to be selected, and the adjacent voltage to be selected includes but is not limited to the following steps:

[0073] According to the target wavelength, an adjacent wavelength to be selected that meets preset requirements is selected from the adjacent wavelengths to be selected as the target adjacent wavelength;

[0074] Selecting an adjacent voltage to be selected corresponding to the target adjacent wavelength from the adjacent voltages to be selected as the target adjacent voltage;

[0075] A plurality of target voltages are calculated based on the target wavelength, the target adjacent wavelength and the target adjacent voltage.

[0076] It can be understood that since there can be countless adjacent wavelengths of the target wavelength, this embodiment selects the target adjacent wavelength by the difference between the target wavelength and the adjacent wavelength, that is, two adjacent wavelengths to be selected with the smallest difference between the adjacent wavelength to be selected and the target wavelength are selected as the target adjacent wavelengths, and the target wavelength is located between the two target adjacent wavelengths. Then, the adjacent voltage to be selected corresponding to the target adjacent wavelength is selected as the target adjacent voltage, thereby effectively improving the calculation accuracy of the target voltage.

[0077] It is understandable that, in this embodiment, several target voltages can be calculated by interpolation calculation formula according to the target wavelength, target adjacent wavelength and target adjacent voltage. Specifically, the process of calculating several target voltages by interpolation formula includes but is not limited to the following steps:

[0078] A first target voltage is calculated according to the target wavelength, the first adjacent wavelength, the second adjacent wavelength, the first adjacent voltage and the fifth adjacent voltage;

[0079] A second target voltage is calculated according to the target wavelength, the first adjacent wavelength, the second adjacent wavelength, the second adjacent voltage and the sixth adjacent voltage;

[0080] A third target voltage is calculated according to the target wavelength, the first adjacent wavelength, the second adjacent wavelength, the third adjacent voltage and the seventh adjacent voltage;

[0081] A fourth target voltage is calculated according to the target wavelength, the first adjacent wavelength, the second adjacent wavelength, the fourth adjacent voltage and the eighth adjacent voltage;

[0082] Among them, the target voltages include a first target voltage, a second target voltage, a third target voltage and a fourth target voltage; the target adjacent wavelengths include a first adjacent wavelength and a second adjacent wavelength; the target adjacent voltages corresponding to the first adjacent wavelength include a first adjacent voltage, a second adjacent voltage, a third adjacent voltage and a fourth adjacent voltage; the target adjacent voltages corresponding to the second adjacent wavelength include a fifth adjacent voltage, a sixth adjacent voltage, a seventh adjacent voltage and an eighth adjacent voltage.

[0083] For example, four target voltages y corresponding to the target wavelength x are required. a1 ,y a2 ,y a3 and a4 , it is known that the target adjacent voltages corresponding to the first adjacent wavelength x1 include y1 a1 ,y1 a2 ,y1 a3 and y1 a4 , the target adjacent voltage corresponding to the second adjacent wavelength x2 includes y2 a1 ,y2 a2 ,y2 a3 and y2 a4 , and if Figure 2 As shown, the target wavelength x is located between the first adjacent wavelength x1 and the second adjacent wavelength x2, and the target adjacent voltage y1 corresponding to the first adjacent wavelength x1 is a1 , the target adjacent voltage y2 corresponding to the second adjacent wavelength x2 a1 For example, based on Figure 2 The target voltage y corresponding to the target wavelength x can be obtained a1 The calculation formula is as follows:

[0084]

[0085] The calculation formula for the target voltage corresponding to the target wavelength x is the same as above and will not be repeated here.

[0086] By calculating respectively in the above manner, the four voltages corresponding to any target wavelength x can be quickly obtained, and then the four target voltages are set in the MEMS of the hyperspectral camera, so that the hyperspectral camera can be controlled to output the corresponding spectral image. Specifically, after obtaining the four target voltages, the voltage control point of the target voltage in the hyperspectral camera is obtained, and then the control voltage corresponding to the control point is set according to the target voltage.

[0087] It can be understood that after obtaining the control voltage, this embodiment inputs the control voltage into the control point corresponding to the hyperspectral camera to control the conductive plate in the hyperspectral camera to generate electrostatic force, and then obtains the cavity distance obtained by the electrostatic force driving the conductive plate, and then determines the output band of the hyperspectral camera according to the cavity distance, so that the hyperspectral camera can output a spectral image corresponding to the target wavelength.

[0088] In the embodiment of the present application, taking the application to monarch NIR spectral camera as an example, the wavelength range of the camera is between 713 nanometers and 920 nanometers. The 4 voltage data corresponding to 10 uniformly distributed wavelengths obtained through experiments are shown in Table 1:

[0089] Table 1

[0090]

[0091]

[0092] Assume that a spectral image with a target wavelength of 810 nanometers is required. It is known that 810 nanometers falls between the 805 nanometer and 828 nanometer bands of the existing voltage data. Therefore, 805 nanometers and 828 nanometers are used as target adjacent wavelengths, and their corresponding voltages are used as target adjacent voltages. Then, the interpolation formula is used to calculate the four target voltages (a1, a2, a3, and a4) corresponding to the target wavelengths:

[0093]

[0094] Then the target voltage group [24.7521, 31.4035, 35.4114, 28.7601] corresponding to 810 nanometers calculated above is set in the MEMS, and a monochromator is used to generate 810 nanometers of light. Then a spectral camera is used to obtain a spectral image at this wavelength. The spectral response curve is shown in the figure. Figure 3 As shown. Due to the characteristics of the FP cavity spectral camera technology principle, there will be a certain error in the center wavelength. The error of monarch NIR spectral camera is ±5 nanometers. Figure 3 From the experimental results shown, the central wavelength of the actual spectrum image and the central wavelength of the light generated by the monochromator have an error of only 2 nanometers, which is acceptable. Therefore, this experiment also fully illustrates the reliability of the method of the present application.

[0095] In summary, the method of the present application can obtain data of any wavelength and corresponding voltage with a small number of anchor point data, thus eliminating the need for a large number of experiments and the need to add additional hardware equipment, effectively reducing workload and equipment costs, and providing users with spectral images corresponding to multiple wavelengths.
