[0002] Spectral imaging is a novel, rapid, and real-time monitoring method. Compared to conventional RGB cameras, spectral cameras have more spectral bands, and each pixel carries spectral information, making them more widely applicable. For example, in agricultural monitoring, such as monitoring mulberry tree pests and diseases or detecting crop nutrient deficiencies, it is necessary to acquire spectral image information in multiple bands, including red, green, blue, and near-infrared, to enable analysis of mulberry tree pests and deficiencies in water and fertilizer. To obtain spectral information in different wavelength ranges, filters of different bands are required. Therefore, current lenses typically incorporate a fixed multispectral array, which contains multiple filters of different bands to acquire spectral information in various wavelength ranges.

[0003] However, in practical use, it is necessary to flexibly select the required wavelength filter according to actual needs. Therefore, how to achieve switching between different wavelengths is a problem that this application urgently needs to solve. Utility Model Content

[0004] The purpose of this application is to provide a filter switching structure, lens, and camera device, which aims to solve the problem of how to achieve flexible switching between different wavelengths.

[0005] In a first aspect, embodiments of this application provide a filter switching structure, including a filter, a filter mounting base, and a driving mechanism; The filter mounting base is used to be installed inside the lens housing. The filter is installed on the filter mounting base and the filter has at least two filter areas with different filter bands. The at least two filter areas are arranged sequentially along a direction perpendicular to the optical axis of the lens. The driving mechanism includes a driving component and a transmission component. The driving component is disposed inside the housing, and the transmission component is disposed on the filter mounting base. The driving component includes a driving motor and a gear assembly, and the transmission component includes a transmission rack. The driving motor is in transmission cooperation with the gear assembly, and the gear assembly meshes with the transmission rack, so that when the driving component drives the transmission component to move, it drives the filter mounting base to move, thereby switching any one of the at least two filter areas to move into the optical path of the lens. The filter mounting base is provided with a first movable guide structure, and the housing is provided with a second movable guide structure. The first movable guide structure and the second movable guide structure cooperate to guide the movement of the filter mounting base.

[0006] In some embodiments, there are at least two driving mechanisms, and the at least two driving mechanisms are respectively disposed on both sides of the filter mounting base; The gear assembly includes a master gear and a driven gear. The master gear is rotatably disposed within the housing and engages with the output shaft of the drive motor. The driven gear is rotatably disposed within the housing and meshes with both the master gear and the transmission rack. The radius of the master gear is larger than the radius of the driven gear.

[0007] In some embodiments, one of the first movable guide structure and the second movable guide structure is a guide rod, and the extending direction of the guide rod is parallel to the moving direction of the filter mounting base; the other of the first movable guide structure and the second movable guide structure is a guide hole through which the guide rod can pass.

[0008] In some embodiments, there are at least two guide rods, which are spaced apart along an arrangement direction perpendicular to the filter area, and there are at least two guide holes, which correspond one-to-one with the at least two guide rods.

[0009] In some embodiments, the filter mounting base includes at least four mounting frames connected end to end, all of which together enclose a mounting opening, and the filter is disposed within the mounting opening and bonded to the inner wall of the mounting opening.

[0010] Secondly, embodiments of this application also provide a lens, including a lens element, a housing, a photosensitive element, and a filter switching structure; The lens is disposed inside the housing, the photosensitive element is located outside the housing, and a light-transmitting hole is provided on the housing at a position corresponding to the photosensitive element; the lens, the filter switching structure, and the photosensitive element are arranged sequentially along the optical path of the lens.

[0011] Thirdly, embodiments of this application also provide a camera device, including a filter switching structure or a lens.

[0012] The beneficial effects of this utility model are: This utility model provides a filter switching structure, a lens, and a camera device. The filter switching structure includes a filter, a filter mounting base, and a driving mechanism. The filter mounting base is used to mount the filter inside the lens housing. The filter is mounted on the filter mounting base and has at least two filtering regions with different filtering bands. The at least two filtering regions are arranged sequentially along a direction perpendicular to the optical axis of the lens, so that different spectral information can be obtained by allowing light to pass through different filtering regions according to actual needs, thereby meeting different usage requirements.

[0013] Simultaneously, a drive mechanism, a filter mounting base, a transmission structure, and a guiding mechanism are configured to drive the filter mounting base to move smoothly in a preset direction along the arrangement of the filter areas. Furthermore, the gear and rack mechanism work together to precisely control the movement, thereby achieving smooth and accurate switching of any one of the at least two filter areas onto the lens's optical path. In other words, the lens of this embodiment contains only one filter, and at least two filter areas of different wavelengths are formed on the filter, enabling the separation and detection of light of different wavelengths and the acquisition of corresponding spectral information.

[0014] Compared to the related technologies that use multiple filters of different wavelengths to separate and detect light of different wavelengths, the lens of this utility model embodiment has fewer filters, which facilitates miniaturization and reduces component costs.

[0015] When it is necessary to allow light to pass through a filter area of ​​a certain wavelength, simply drive the filter mounting base to move via the drive mechanism to move the filter, thereby moving the filter area of ​​the required wavelength onto the optical path. The entire switching operation is simple and quick. Attached Figure Description

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0021] Reference Figures 1 to 5 As shown in the figure, this application embodiment provides a filter switching structure, including a filter 100, a filter mounting base 200, and a driving mechanism 300.

[0022] The filter mounting base 200 is used to be disposed inside the housing 410 of the lens 400. The filter 100 is disposed on the filter mounting base 200, and the filter 100 is provided with at least two filter areas 110 with different filter bands. The at least two filter areas 110 are arranged sequentially along a direction perpendicular to the optical axis of the lens 400.

[0023] The drive mechanism 300 is disposed within the housing 410 and is in drive cooperation with the filter mounting base 200 to drive the filter mounting base 200 to move along the arrangement direction of the filter areas 110, so as to switch any one of the at least two filter areas 110 to move into the optical path of the lens 400.

[0024] In a specific implementation, the filter mounting base 200 is movably disposed within the housing 410 of the lens 400. The filter 100 is fixed on the filter mounting base 200 and can move with the movement of the filter mounting base 200. At least two filtering regions 110 with different filtering bands can be formed on the filter 100. For example, the filter 100 can be a square sheet, which can be divided into at least two regions along a direction perpendicular to the optical axis. Each region forms a filtering region 110 with a different wavelength. Different wavelengths of light can be separated and analyzed through the different filtering regions 110, which can be used for the analysis and detection of material components.

[0025] For example, in order to detect the health status of vegetation, light can be separated and detected through at least two filter areas 110 with different filter bands. When light passes through different filter areas 110, it will form images with different gray levels on the photosensitive element 500 of the lens 400. That is, after the photosensitive element 500 receives the light passing through the corresponding filter area 110, it will generate an image corresponding to the filter band of the filter area 110. Then, by comparing the images with different gray levels, the health status of vegetation can be analyzed.

[0026] For example, two filtering regions 110 can be formed on the filter 100, or they can be formed as shown in the figure. Figure 4 The three filter regions 110 shown can be used, or four or more filter regions 110 can be formed.

[0027] For example, the method of forming filter regions 110 with different filter bands on the filter 100 can be to form the filter regions 110 on the substrate of the filter 100 by coating technology, or by photolithography, dyeing or coloring technology, or inkjet printing, laser processing and micro-nano processing to form the filter regions 110 of the corresponding bands on the substrate.

[0028] Furthermore, a drive mechanism 300 is also provided inside the housing 410. The drive mechanism 300 is in transmission cooperation with the filter mounting base 200, thereby driving the filter mounting base 200 to move along the arrangement direction of the filter area 110, so that a certain filter area 110 can be moved into the optical path to realize band switching.

[0029] In practice, at least two filter areas 110 are arranged sequentially along a direction perpendicular to the optical axis. For example, they can be arranged along the height direction of the lens 400, that is, at least two filter areas 110 are arranged along a direction perpendicular to the optical axis. Figure 5 As shown, the filters are arranged sequentially in the vertical direction. Therefore, when it is necessary to switch different filter areas 110 to be located on the optical path, the filter mounting base 200 can be moved up and down by the drive mechanism 300 to move the required filter area 110 to be located on the optical path.

[0030] Alternatively, in other implementations, at least two filter areas 110 can be arranged sequentially along a direction perpendicular to the optical axis. For example, they can be arranged along the width of the lens 400, i.e., at least two filter areas 110 are arranged along a direction perpendicular to the optical axis. Figure 5 As shown, the filters are arranged sequentially in the left and right directions. Therefore, when it is necessary to switch different filter areas 110 to be located on the optical path, the filter mounting base 200 can be moved left and right by the drive mechanism 300 to move the required filter area 110 to be located on the optical path.

[0031] The filter switching structure of this embodiment includes a filter 100, a filter mounting base 200, and a driving mechanism 300. The filter mounting base 200 is disposed within the housing 410 of the lens 400. The filter 100 is mounted on the filter mounting base 200, and the filter 100 has at least two filter regions 110 with different filter bands. These at least two filter regions 110 are arranged sequentially along a direction perpendicular to the optical axis of the lens 400, allowing light to pass through different filter regions 110 to obtain corresponding spectral information according to actual needs, thereby meeting different usage requirements. Simultaneously, the driving mechanism 300 is configured to drive the filter mounting base 200 to move along the arrangement direction of the filter regions 110, thereby switching either of the at least two filter regions 110 onto the optical path of the lens 400. In other words, the filter switching structure of this embodiment only has one filter 100, and at least two filter regions 110 of different wavelengths are formed on the filter 100 to achieve the separation and detection of light of different wavelengths and obtain the corresponding spectral information. Compared with the related technology that sets multiple filters 100 of different wavelengths to achieve the separation and detection of light of different wavelengths, the filter switching structure of this embodiment and the number of filters 100 of the lens 400 and the camera device adapted to it are small, thus facilitating miniaturization and reducing component costs. In addition, when it is necessary for light to pass through the filter region 110 of a certain wavelength, it is only necessary to drive the filter mounting base 200 to move by the drive mechanism 300 to move the filter 100, so as to move the filter region 110 of the required wavelength to the optical path. The entire switching operation is simple and quick.

[0032] Reference Figure 4 , Figure 5 As shown, in some embodiments, the drive mechanism 300 includes a drive component 310 and a transmission component 320. The drive component 310 is disposed in the housing 410 and is in transmission cooperation with the transmission component 320. The transmission component 320 is disposed on the filter mounting base 200 so that when the drive component 310 drives the transmission component 320 to move, it drives the filter mounting base 200 to move.

[0033] In a specific implementation, to facilitate the movement and switching of the filter area 110, the drive component 310 and the transmission component 320 can be configured to cooperate in transmission. The transmission component 320 is located on the filter mounting base 200. Therefore, when the drive component 310 drives the transmission component 320 to move, it can drive the filter mounting base 200 to move, which in turn drives the filter 100 to move, so that different filter areas 110 on the filter 100 can be moved to the optical path to realize the corresponding filtering operation.

[0034] Reference Figure 4 , Figure 5 As shown, in some embodiments, the drive assembly 310 includes a drive motor 311 and a gear assembly 312, and the transmission component 320 includes a transmission rack. The drive motor 311 and the gear assembly 312 are in transmission cooperation, and the gear assembly 312 meshes with the transmission rack.

[0035] In practice, when it is necessary to switch the position of the filter area 110, the drive motor 311 can be started. The drive motor 311 drives the gear assembly 312 to rotate. The gear assembly 312 rotates and meshes with the transmission rack to drive the transmission rack to move, which in turn drives the filter mounting base 200 connected to the transmission rack to move. The entire drive mechanism 300 is not only simple in structure but also easy to operate.

[0036] In practice, the drive rack can be snapped into the filter mounting base 200 or connected via fasteners, or the drive rack can be integrally formed on the filter mounting base 200. Furthermore, the extension direction of the drive rack is parallel to the arrangement direction of at least two filter areas 110 to ensure that the filter mounting base 200 can smoothly move the filter areas 110 so that the corresponding filter areas 110 can be moved into the optical path when the filter mounting base 200 moves.

[0037] Alternatively, in other implementations, the transmission component 320 can also be a worm gear, and the drive assembly 310 includes a drive motor 311 and a turbine. The drive motor 311 drives the turbine to rotate, and the turbine and worm gear mesh, thereby driving the worm gear to move when the turbine gear rotates. The worm gear is connected to the filter mounting base 200, and then ultimately drives the filter mounting base 200 to move.

[0038] In addition, an opening may be provided on the outer wall of the housing 410 to expose part of the drive motor 311, which not only facilitates heat dissipation but also makes it easy to start and stop the drive motor 311.

[0039] In some embodiments, there are at least two drive mechanisms 300, which are respectively disposed on both sides of the filter mounting base 200.

[0040] In a specific implementation, there can be two drive mechanisms 300, which are respectively located on both sides of the filter mounting base 200. Thus, the filter mounting base 200 can be moved synchronously by the two drive mechanisms 300, so that the movement of the filter mounting base 200 is more stable and there will be no problem of misalignment that would prevent the filter area 110 from being moved accurately into the optical path, thus affecting stable imaging.

[0041] Reference Figure 4 , Figure 5 As shown, the gear assembly 312 includes a master gear 313 and a driven gear 314. The master gear 313 is rotatably disposed within the housing 410 and is in transmission engagement with the output shaft of the drive motor 311. The driven gear 314 is rotatably disposed within the housing 410 and meshes with the master gear 313 and the transmission rack, respectively. The radius of the master gear 313 is larger than the radius of the driven gear 314.

[0042] In a specific implementation, an output gear 315 can be set on the output shaft of the drive motor 311 to mesh with the main gear 313, the main gear 313 to mesh with the driven gear 314, and the driven gear 314 to mesh with the transmission rack, so as to transmit the power of the output shaft of the drive motor 311 to the transmission rack, so that the transmission rack moves to drive the filter mounting base 200 to move.

[0043] In addition, the radius of the main gear 313 is set to be larger than that of the driven gear 314. This allows the transmission rack to move faster and more precisely, provided that the maximum speed of the drive motor 311 is constant.

[0044] Reference Figure 4 , Figure 5 As shown, in some embodiments, a first moving guide structure 210 is provided on the filter mounting base 200, and a second moving guide structure 411 is provided inside the housing 410. The first moving guide structure 210 and the second moving guide structure 411 cooperate to guide the movement of the filter mounting base 200.

[0045] In specific implementation, by setting the first moving guide structure 210 and the second moving guide structure 411 to cooperate, when the driving mechanism 300 drives the filter mounting base 200 to move along the arrangement direction of the filter area 110, the movement of the filter mounting base 200 can be more stable and will not be tilted. This can avoid the problem of the filter 100 being tilted, which would prevent the filter area 110 from being moved accurately into the optical path and thus affect stable imaging.

[0046] Reference Figure 4 , Figure 5As shown, in some embodiments, one of the first movable guide structure 210 and the second movable guide structure 411 is a guide rod 412, the extension direction of the guide rod 412 is parallel to the moving direction of the filter mounting base 200, and the other of the first movable guide structure 210 and the second movable guide structure 411 is a guide hole 211 through which the guide rod 412 can pass.

[0047] In a specific implementation, a guide rod 412 can be provided inside the housing 410, and a guide hole 211 can be provided on the filter mounting base 200. The guide rod 412 is located inside the guide hole 211, so that the filter mounting base 200 can move smoothly along the guide rod 412.

[0048] Alternatively, in other implementations, a guide post can be provided inside the housing 410, with a guide hole 211 inside the guide post, and a guide rod 412 can be provided on the filter mounting base 200, which can also guide the movement of the filter mounting base 200.

[0049] In addition, a lubricating material, such as lubricating oil, can be provided between the guide rod 412 and the guide hole 211 to make the movement of the filter mounting base 200 smoother.

[0050] Reference Figure 4 , Figure 5 As shown, in some embodiments, there are at least two guide rods 412, which are spaced apart along an arrangement direction perpendicular to the filter area 110, and there are at least two guide holes 211, which correspond one-to-one with the at least two guide rods 412.

[0051] This configuration allows the movement of the filter mounting base 200 to be guided by the cooperation of at least two guide rods 412 and at least two guide holes 211, thereby further improving the stability of the movement of the filter mounting base 200.

[0052] For example, there may be two guide rods 412 and two guide holes 211. Alternatively, in other implementations, there may be three or more guide rods 412 and three or more guide holes 211.

[0053] Reference Figures 3 to 5 As shown, in some embodiments, the filter mounting base 200 includes at least four mounting frames 220 connected end to end. All mounting frames 220 together enclose a mounting opening 230. The filter 100 is disposed within the mounting opening 230 and is bonded to the inner wall of the mounting opening 230, thereby achieving a reliable connection between the filter 100 and the filter mounting base 200. The filter 100 is located within the mounting opening 230, which can prevent the filter mounting base 200 from blocking light and affecting the filtering operation of the filtering area 110.

[0054] Reference Figures 1 to 5 As shown, this application embodiment also provides a lens 400, including a lens, a housing 410, a photosensitive element 500, and a filter switching structure.

[0055] The lens is located inside the housing 410, the photosensitive element 500 is located outside the housing 410, and a light-transmitting hole 413 is provided on the housing 410 at a position corresponding to the photosensitive element 500; the lens, the filter switching structure and the photosensitive element 500 are arranged sequentially along the optical path direction of the lens 400.

[0056] Specifically, after the light enters through the housing 410, it is focused by the lens. The focused light is then filtered by different filter areas 110, forming images of different grayscale on the photosensitive element 500. Thus, the corresponding detection results can be obtained based on the analysis of different images.

[0057] In a specific implementation, the housing 410 may include a main housing 414 and a base plate 415 located on the side of the main housing 414 near the photosensitive element 500. The filter switching structure is located inside the main housing 414 and is set near the base plate 415. The base plate 415 is provided with a light-transmitting hole 413 so that the light filtered by the filter area 110 can pass through and be projected onto the photosensitive element 500 to generate a grayscale image.

[0058] The photosensitive element 500 can be fixed to the base plate 415 by screws or other fasteners.

[0059] For example, the photosensitive element 500 may be an image sensor.
