Description

Technical Field

[0001] The invention belongs to the field of macro image equipment, and in particular relates to an assembled macro image acquisition terminal. Background Art

[0002] At present, macro photography is one of the specialties of digital cameras. Using macro photography, you can turn very ordinary scenes into dramatic scenes. Macro is particularly good at expressing small things such as flowers, birds, fish and insects. It can fully display the details and can also observe the organization or texture structure of objects, such as: the texture structure of wood cross-section, gemstone antiques, etc.

[0003] However, when the customs department takes photos on site, at least two workers are needed, one to take photos and the other to compensate for the exposure from one side. Therefore, there are the following defects:

[0004] 1) Due to manual focusing, it is difficult to ensure that the focusing distance is the same each time. As a result, the photos taken have different standards and it is impossible to accurately obtain the texture structure information of the object;

[0005] 2) During the shooting process, it is difficult to obtain satisfactory photos stably because the photographer will inevitably shake the lens;

[0006] 3) When compensating exposure, the exposure effect is affected by the different angles of the light source and the interference of external light. At the same time, the side light will cause shadows on the subject, thus affecting the shooting effect.

[0007] 4) It is expensive and inconvenient to carry. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved assembled macro image acquisition terminal.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] Preferably, the end surface of the acquisition base away from the adapter is arranged parallel to the lens of the macro lens. In this way, after being connected to a shooting device (mobile phone), it can be ensured that the lens of the shooting device is parallel to the end surface of the acquisition base away from the adapter, so as to obtain a magnified picture of the structure of the surface of the sample to be detected at the same focal length.

[0012] According to a specific implementation and preferred aspect of the present invention, the acquisition head further comprises a soft light ring arranged on the end face of the acquisition base away from the adapter, wherein the end face of the soft light ring away from the acquisition base is arranged parallel to the lens of the macro lens.

[0013] Specifically, the interior of the soft light ring is formed with a first annular cavity and a second annular cavity from the inside to the outside, wherein the inner diameter of the second annular cavity is larger than the inner diameter of the first annular cavity, the inner diameter of the first annular cavity is larger than the outer diameter of the lens, and the center lines of the first annular cavity and the second annular cavity coincide with the center line of the lens.

[0014] According to another specific implementation and preferred aspect of the present invention, a third annular cavity is further provided in the soft light ring, wherein the third annular cavity is formed by extending outward from the outer end surface of the second annular cavity, and the soft light ring is set up from the end surface of the third annular cavity to form the surface of the sample to be tested or the platform surface for placing the test sample.

[0015] Preferably, the lamp is ring-shaped and is disposed on the inner wall of the collection base, wherein the light of the lamp is transmitted through the soft light ring to illuminate the image collection area in the form of softened light.

[0016] Specifically, the lamp includes an annular light belt, a plurality of light bodies arranged on the annular light belt, a lithium battery arranged on the annular light belt, a power supply and a control switch, wherein the light body is an LED lamp. Through the rechargeable lithium battery, the lamp can be disconnected from the power supply and used independently, which is more convenient to use.

[0017] Furthermore, the center line of the annular light strip is arranged to coincide with the center line of the lens, so that the annular fill light effect is optimal.

[0018] Preferably, the collection base is also provided with a charging interface connected to a power source.

[0019] In addition, the adapter includes a first connecting portion connected to the macro lens and a second connecting portion detachably connected to the collection base, wherein the first connecting portion and the second connecting portion are internally connected to form a perspective cavity, and an annular groove is formed at the end of the second connecting portion away from the macro lens, and an annular protrusion matching the annular groove is provided on the outer periphery of the collection base.

[0020] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0021] On the one hand, the macro lens and the acquisition head of the present invention can be quickly assembled through an adapter and thus can be conveniently carried. At the same time, they can not only be attached to the surface of an object to photograph the microscopic structure of a plane, but also can photograph tiny objects (such as insects, jewelry, flowers, etc.).

[0032] like Figure 1 As shown, the assembled macro image acquisition terminal of this embodiment includes a macro lens 1, an adapter 2 connected to the outer end of the macro lens 1, and a collection head 3 arranged at the outer end of the adapter 2 and capable of compensating for exposure.

[0033] The collection head 3 includes a collection base 30 formed with an annular cavity, a soft light ring 31 and a lamp 32 arranged on the collection base 30, and the adapter 2, the soft light ring 31, and the surface of the sample to be detected or the adapter 2, the soft light ring 31, and the platform surface where the detection sample is placed form a closed image collection area.

[0034] The end surface of the collection base 30 away from the adapter 2 is arranged parallel to the lens 10 of the macro lens 1. After being connected to the shooting device (mobile phone), it can ensure that the lens of the shooting device is parallel to the end surface of the collection base away from the adapter, so as to obtain a structural enlarged picture of the surface of the sample to be detected at the same focal length.

[0035] The soft light ring 31 is arranged at the end of the collection base 30 away from the adapter 2, and the end surface of the soft light ring 31 away from the collection base 30 is arranged parallel to the lens 10 of the macro lens 1. In this way, when taking photos with a fixed focus, it is ensured that the lens is parallel to the surface of the sample to be tested, thereby providing the necessary conditions for obtaining satisfactory photos.

[0036] In this example, the interior of the soft light ring 31 is formed with a first annular cavity a1, a second annular cavity a2, and a third annular cavity a3 formed by the second annular cavity a2 extending outward from the outer end surface in sequence from the inside to the outside.

[0037] The first annular cavity a1 has a rectangular cross section, the second annular cavity a2 and the third annular cavity a3 have isosceles trapezoidal cross sections, and the soft light ring 31 is set up from the end surface of the third annular cavity a3 on the surface of the sample to be tested or the surface of the platform where the test sample is placed. This arrangement creates better lighting conditions and makes the focus of the macro lens more accurate when taking pictures.

[0038] In this example, the center lines of the first annular cavity a1 , the second annular cavity a2 , and the third annular cavity a3 coincide with the center line of the lens 10 .

[0039] Meanwhile, in this example, the inner diameter of the first annular cavity a1 is larger than the outer diameter of the lens 10, and the inner diameter of the inner end of the second annular cavity a2 is larger than the inner diameter of the first annular cavity a1. At this time, the exposure effect is the best.

[0040] The lamp 32 includes an annular light belt arranged along the circumference of the collection base 30, a plurality of LED lights arranged on the annular light belt, a power source and a switch, wherein the power source is a rechargeable lithium battery. By setting the annular light belt, the light can be compensated in all directions to the collection area, thereby facilitating taking pictures; and the lamp 32 is equipped with a lithium battery, so that the lithium battery can also be directly powered by the lamp 32, making it more convenient to use.

[0041] At the same time, it should be particularly noted that the center line of the annular light strip is arranged to coincide with the center line of the lens 10. In this way, the effect of the annular fill light is best.

[0042] In addition, a charging interface c connected to a power source is also provided on the acquisition base 30. In this way, the bright body can be directly powered by the mobile phone, further increasing the practicality of the macro image acquisition terminal.

[0043] Combination Figure 2As shown, the adapter 2 includes a first connecting portion 21 connected to the macro lens 1 and a second connecting portion 22 detachably connected to the collection base 30, wherein the first connecting portion 21 and the second connecting portion 22 are connected to form a perspective cavity q, and an annular groove b1 is formed at the end of the second connecting portion 22 away from the macro lens 1, and an annular protrusion b2 matching the annular groove b1 is provided on the outer periphery of the collection base 30.

[0044] Therefore, this embodiment has the following advantages:

[0045] (1) The ring light around the camera can provide accurate ring fill light centered on the object being photographed (currently there is no ring fill light centered on the mobile phone camera), which can greatly eliminate the shadow of the object being photographed compared to other side lights;

[0046] (2) With a variety of fixing clips, the fill light camera can be flexibly replaced for multi-camera mobile phones;

[0047] (3) The size is very small, which can meet the high flexibility requirements of macro photography and is highly portable;

[0048] (4) Power supply is easy to obtain and the mobile phone can be powered directly;

[0049] (5) The macro lens and acquisition head can be quickly assembled through the adapter and are easy to carry. At the same time, they can not only be attached to the surface of an object to shoot the microscopic structure of the plane, but also can shoot tiny objects (such as insects, jewelry, flowers, etc.);

[0050] (6) The macro image acquisition terminal and macro shooting equipment are used together, and the lighting is used to fill in the image acquisition area. This not only shortens the focus distance under the macro lens, but also provides a stable and shadow-free fill-in lighting condition for the lens during shooting, thereby enabling fast and accurate acquisition of photos with good effects (such as high clarity). At the same time, it can be operated by one person, which is very convenient.

[0051] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
