Technical Field
[0001] The utility model relates to the field of digital cameras, in particular to a fusion photography digital camera. Background Art
[0002] When a camera takes a photo, according to the types and specifications of the set filters, the image sensor can obtain light within a corresponding wavelength range.
[0003] Currently, although the front end of the lens of a traditional camera can replace corresponding optical lenses according to user needs, only a single filter can be set, and it is impossible to obtain light images of certain specific areas by setting multiple wavelength filters, so the applicability is poor. For example, when conducting sewage detection records, some components of the sewage can reflect light within a specific wavelength range, and by setting a single filter, the image sensor can only obtain the image within this wavelength range, which cannot prove the specific environmental scene of the sewage, and its evidentiary effect in forensic science is not obvious. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a fusion photography digital camera, which can set two sets of brackets and combine filters with different bandwidths according to needs to obtain images with more wavelength combinations.
[0005] To achieve the above purpose, the utility model provides a fusion photography digital camera, which includes a camera body provided with an image sensor, and the camera body is connected with a lens mount; an ultraviolet lens assembly is provided on the lens mount, and at least two brackets are movably connected to the lens mount. Each bracket is located in front of and / or behind the ultraviolet lens assembly, and each bracket, the ultraviolet lens assembly and the image sensor are arranged on the same straight line. At least two juxtaposed empty frames are provided on each bracket, and filters are provided in at least one empty frame of each bracket.
[0006] As a further improvement of the utility model, a sliding groove is provided on the lens mount, and the bracket is slidably connected with the sliding groove.
[0007] As a further improvement of the utility model, a sliding positioning structure is provided between the bracket and the sliding groove.
[0008] As a further improvement of the utility model, the sliding positioning structure includes a clamping block and a positioning groove that are clamped and matched with each other. One of the clamping block and the positioning groove is provided on the inner side wall of the sliding groove, and the other is provided on the bracket.
[0009] As a further improvement of the utility model, a driving mechanism is connected between each bracket and the lens mount.
[0010] As a further improvement of the present utility model, the driving mechanism includes a rack and a gear that mesh with each other. The rack is arranged on the bracket, and the gear is rotatably connected to the lens mount and linked with the motor.
[0011] As a further improvement of the present utility model, the bracket includes a first bracket and a second bracket, and the first bracket, the ultraviolet lens assembly, the second bracket, and the image sensor are arranged in sequence.
[0012] Beneficial effects
[0013] Compared with the prior art, the advantages of the fusion photography digital camera of the present utility model are as follows:
[0014] 1. At least two juxtaposed empty frames are provided on both the first bracket and the second bracket, and at least one empty frame of each of the first bracket and the second bracket is provided with a filter. When taking long-exposure photos, by using the first bracket and the second bracket to switch filters with different bandwidths during the long exposure process, the image sensor of the camera can record images of different wavelength combinations, that is, fusion photography, which has a wide range of applications. For example, it can be used in fields such as sewage detection records. Different substances' pollution states can be recorded with different wavelengths, and it can overcome the problem that sewage detection only detects the sewage phenomenon and cannot prove the specific environmental scene of the sewage.

[0022] Embodiments of the present utility model will now be described with reference to the accompanying drawings.
[0023] Embodiment 1
[0024] A fusion photography digital camera of the present solution includes a camera body 1 provided with an image sensor 3, and the camera body 1 is connected to a lens mount 2. An ultraviolet lens assembly 4 is provided on the lens mount 2, and at least two brackets are movably connected to the lens mount 2. Each bracket is located in front of and / or behind the ultraviolet lens assembly 4. Each bracket, the ultraviolet lens assembly 4, and the image sensor 3 are arranged on the same straight line. At least two juxtaposed empty frames are provided on each bracket, and a filter is provided in at least one empty frame of each bracket.
[0025] The detailed implementation manners of the present utility model are as Figures 1 to 2 shown. The fusion photography digital camera includes a camera body 1 provided with an image sensor 3, and the camera body 1 is connected to a lens mount 2. An ultraviolet lens assembly 4 is provided on the lens mount 2, and a first bracket 5 and a second bracket 6 are movably connected to the lens mount 2. The first bracket 5, the ultraviolet lens assembly 4, the second bracket 6, and the image sensor 3 are arranged in sequence. At least two juxtaposed empty frames are provided on both the first bracket 5 and the second bracket 6, and a filter is provided in at least one empty frame of each of the first bracket 5 and the second bracket 6.
[0026] In this embodiment, three first empty frames 51 are provided on the first bracket 5, and three second empty frames 61 are provided on the second bracket 6. Two of the first empty frames 51 are provided with first filters 52, and the wavelength ranges that the two first filters 52 can pass through are different. The third first empty frame 51 is not provided with a filter. Two of the second empty frames 61 are provided with second filters 62, and the wavelength ranges that the two second filters 62 can pass through are different. The third second filter 62 is not provided with a filter.
[0027] The ultraviolet lens assembly 4 can adopt a single lens or multiple lenses arranged in sequence along the optical path. The wavelength range of the light that the lens can pass through is 200 - 2000 nm, and the induction wavelength range of the image sensor 3 is 200 - 1100 nm.
[0028] The lens mount 2 is provided with a first sliding groove and a second sliding groove. The first bracket 5 is slidably connected to the first sliding groove, and the second bracket 6 is slidably connected to the second sliding groove. A sliding positioning structure is provided between the first bracket 5 and the first sliding groove and between the second bracket 6 and the second sliding groove. The first sliding groove and the second sliding groove can be linear sliding grooves or arc sliding grooves. When the first sliding groove and the second sliding groove are linear sliding grooves, the first bracket 5 and the second bracket 6 are in a straight plate shape, and each empty frame is arranged in a straight line; when the first sliding groove and the second sliding groove are arc sliding grooves, the first bracket 5 and the second bracket 6 are in a circular ring shape, and each empty frame is arranged around the rotation axis of the bracket. In this embodiment, the first sliding groove and the second sliding groove are linear sliding grooves, and the first bracket 5 and the second bracket 6 are in a straight plate shape.
[0029] The sliding positioning structure includes a clamping block 71 and a positioning groove 72 that are clamped and matched with each other. One of the clamping block 71 and the positioning groove 72 is arranged on the inner side wall of the first sliding groove and the second sliding groove, and the other is arranged on the first bracket 5 and the second bracket 6. In this embodiment, the clamping block 71 is arranged on the inner side wall of the first sliding groove and the second sliding groove, and the positioning groove 72 is arranged on the first bracket 5 and the second bracket 6.
[0030] Taking the first bracket 5 as an example, after a person manually or electrically pushes the first bracket 5 to slide it along the first sliding groove for a certain distance, the clamping block 71 is clamped and matched with the corresponding positioning groove 72. At this time, the corresponding first empty frame 51 (with or without a filter)、the ultraviolet lens assembly 4、and the image sensor 3 are in the same straight line. Pushing the first bracket 5 again can disengage the clamping block 71 from the positioning groove 72, allowing the first bracket 5 to continue sliding along the first sliding groove, thereby switching to other filters. The switching and positioning methods of the second bracket 6 are the same.
[0031] Before performing long exposure with this fusion photography digital camera, the first bracket 5 and the second bracket 6 can be operated first to align one of the first filters 52 with the ultraviolet lens assembly 4 and the image sensor 3 in the same straight line, and then long exposure is performed. During this process, the light passing through the first filter 52 is imaged on the image sensor 3; during the long exposure process, the first filter 52 is quickly moved away through the first bracket 5, and at the same time, by operating the second bracket 6, the ultraviolet lens assembly 4、one of the second filters 62、and the image sensor 3 are arranged in the same straight line, and long exposure continues. The light passing through the second filter 62 is imaged on the image sensor 3. After the long exposure is completed, an image formed by the fusion of two wavelengths of the first filter 52 and the second filter 62 can be obtained. In addition, according to needs, switching of three or more different band-pass filters can also be performed during the long exposure process to achieve an image fused by more wavelength ranges.
[0032] Embodiment 2
[0033] As Figure 3As shown, the difference from Embodiment 1 is that drive mechanisms are connected between the first bracket 5 and the lens mount 2, and between the second bracket 6 and the lens mount 2. The drive mechanism includes a rack 81 and a gear 82 that mesh with each other. The rack 81 is arranged on the first bracket 5 and the second bracket 6, and the gear 82 is rotatably connected to the lens mount 2 and linked with the motor. Each drive mechanism can drive the corresponding bracket to move along the chute. Taking the first bracket 5 as an example, when the motor drives the gear 13 to rotate, the first bracket 5 can be driven to slide along the first chute.
[0034] In addition, the drive mechanism can also adopt structures such as linear motors or hydraulic cylinders.
[0035] In addition to the above embodiments, the first bracket 5 and the second bracket 6 can also be arranged in front of or behind the ultraviolet lens assembly 4 at the same time, and the number of brackets can also be three or more. The specific number and position of the brackets are selected according to user requirements.
[0036] The present invention has been described above in conjunction with the best embodiments, but the present invention is not limited to the disclosed embodiments above, and should cover various modifications and equivalent combinations made according to the essence of the present invention.
