DETAILED DESCRIPTION

[0028] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0029] The following describes the implementation methods of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0030] It should be noted that various aspects of the embodiments within the scope of the appended claims are described below. It should be apparent that the aspects described herein can be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on the present application, it should be understood by those skilled in the art that an aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number and aspect described herein can be used to implement the device and / or practice the method. In addition, other structures and / or functionalities other than one or more of the aspects described herein can be used to implement this device and / or practice this method.

[0031] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0032] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0033] Currently, the shooting angle of industrial food sorting machines is limited to a single screen, which can only cover a 180-degree field of view at most. It is unable to capture the full picture of the material, which limits the comprehensive identification of materials such as salad vegetables.

[0034] Existing sorting machines use non-transparent conveyor belts made of PE material, which means that the mainstream machines are limited to single-sided shooting from top to bottom, which limits the camera's shooting coverage and recognition area. The maximum shooting angle does not exceed 180 degrees, which can only reach half of the material.

[0035] In view of this, in the analysis and improvement exploration of the device, it was found that: two sorting machines are used, and a flip structure is installed between them to achieve double-sided shooting of the material to obtain a larger recognition angle, but there are the following problems in the actual operation process:

[0036] First, more space is needed to accommodate the additional machines, causing costs to soar.

[0037] Second, during the flipping process, not only is it difficult to ensure that the material can be completely turned over, but it is also easy to damage the material, thus affecting the quality of the shooting.

[0038] Based on this, the embodiment of this specification proposes a vegetable sorting panoramic shooting device: Figure 1 As shown, a transparent conveying device is used, and shooting modules are installed above and below the food-grade transparent conveyor belt respectively. The vegetables are photographed in all directions through the upper and lower shooting modules, realizing panoramic material identification without blind spots, thereby ensuring product quality during the vegetable sorting process and improving the accuracy and efficiency of sorting.

[0039] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, the embodiment of this specification provides a vegetable sorting panoramic photography device, comprising:

[0041] A transparent conveying device, including a food-grade transparent conveyor belt, for conveying vegetables to be sorted;

[0042] An upper shooting module and a lower shooting module are arranged above and below the food-grade transparent conveyor belt, wherein the upper shooting module is used to obtain the front image of the vegetables to be sorted; and the lower shooting module is used to obtain the back image of the vegetables to be sorted.

[0043] During implementation, the food-grade transparent conveyor belt smoothly transfers the materials (vegetables to be sorted) to the designated shooting area. The upper shooting module located above the food-grade transparent conveyor belt is responsible for shooting the vegetables to be sorted from above and capturing the front image of the vegetables to be sorted.

[0044] The lower shooting module located below the food-grade transparent conveyor belt works in conjunction with the upper shooting module to shoot the vegetables to be sorted from below and capture images of the back of the vegetables.

[0045] It should be emphasized that the food-grade transparent conveyor belt in the transparent conveying device can not only transport materials to the designated shooting area, but also provide the required light transmittance and perspective effects for the lower shooting module below, so that the lower shooting module can clearly obtain the back image of the vegetables to be sorted, ensuring the shooting quality.

[0046] In summary, the vegetable sorting panoramic shooting device composed of a shooting module and a transparent conveying device has a simple overall structure, can realize all-round shooting of vegetables of different types and shapes, provides 360-degree visual coverage without blind spots, and the vegetables will not be contaminated or damaged during the shooting process. Compared with the traditional method that requires multiple machines and complex flipping structures, it occupies less space, has low cost, and can be expanded according to actual needs.

[0047] In one embodiment, the upper shooting module and the lower shooting module are staggeredly arranged above and below the food-grade transparent conveyor belt.

[0048] Specifically, Figure 1 As shown, the distance of the left and right misalignment is L. The distance between the two shooting modules is adjusted according to actual needs to ensure that every side of the vegetable can be photographed, covering the front and back of the vegetable, thereby achieving panoramic recognition without blind spots.

[0049] The staggered design of the upper and lower modules needs to take into account the field of view of the camera 26 and the moving speed of the vegetables on the conveyor belt to ensure the continuity and integrity of the image.

[0050] During implementation, when vegetables pass through the conveyor belt, the upper module and the lower module can capture the front and back of the vegetables respectively, and the overlapping area can provide more image information, which helps to improve the accuracy and robustness of the recognition algorithm.

[0051] In practice, the offset distance L is designed to be half of the field of view of the camera 26. When the vegetables pass through the conveyor belt, the upper module and the lower module can capture the front and back of the vegetables respectively, that is, the entire surface of the vegetables is covered without overlapping or missing in the image, thereby improving the accuracy and efficiency of vegetable sorting.

[0052] Specifically, the offset distance can be adjusted according to actual needs to adapt to different shooting scenes and materials.

[0053] In one embodiment, the upper shooting module and the upper shooting module are installed perpendicular to the direction of the food-grade transparent conveyor belt.

[0054] Specifically, the upper shooting module and the lower shooting module capture images of vegetables from two vertical directions respectively, which helps to reduce shadows and reflections during the shooting process, thereby improving the quality and clarity of the image and providing high-quality visual data for subsequent image processing and analysis.

[0055] In one embodiment, if Figure 3 and Figure 4 As shown, the upper shooting module and / or the lower shooting module includes a fill light unit, and the fill light unit includes a light source and an angle adjustment plate;

[0056] The light source is a high brightness light source 46, which is used to irradiate light to the vegetables to be sorted;

[0057] The angle adjustment plate is used to adjust the irradiation angle of the light source so that the light irradiated according to the irradiation angle covers the vegetables to be sorted.

[0058] Specifically, the light source is installed on the light source mounting plate 32 through the light source connecting plate 29 to ensure the stability of the light source. The high-brightness light source is responsible for providing sufficient brightness so that it can evenly and clearly illuminate the vegetables to be sorted under various lighting conditions, thereby enhancing the clarity and detail of the image, especially in the identification of vegetable surface features.

[0059] During implementation, in order to adapt to vegetables of various shapes and sizes to be sorted, the irradiation angle of the light source is finely adjusted through the light source angle adjustment plate 28, so as to control the direction and coverage of the light, reduce the shadow and reflection problems caused by the surface of the vegetables, and thus improve the visibility of the vegetable features, ensure the quality of image acquisition, and provide accurate data support for subsequent image processing and vegetable sorting.

[0060] In one embodiment, the upper shooting module and / or the lower shooting module further includes a handle, which is disposed on the shooting module and is used to carry the shooting module;

[0061] And / or, the upper shooting module and / or the lower shooting module further includes a protective cover, and the protective cover is detachably arranged on the shooting module.

[0062] Specifically, Figure 3 As described above, the handles 43 can be installed on both sides of the shooting module to facilitate the operator to lift, move and adjust the shooting module from the side.

[0063] The handle 43 can also be installed on the top of the shooting module to facilitate the operator to lift it from above.

[0064] The installation position of the handle can be set according to the size, shape, overall layout of the shooting module and the actual usage requirements of the operator.

[0065] In one embodiment, if Figure 3 As described above, the protective cover 44 is disposed on the shooting module to protect the entire shooting module from dust, moisture or other potential damages.

[0066] In one embodiment, the handle is detachably connected to the shooting module.

[0067] Specifically, it can be removed when it is not needed for transportation or adjustment, thus saving space.

[0068] In one embodiment, the transparent conveying device further comprises: a motor anti-rotation structure;

[0069] The motor anti-rotation structure cooperates with the reduction motor to accurately control the vegetables to be sorted to reach a preset shooting area.

[0070] like Figure 5 As shown, the motor anti-rotation structure 36 fixes the reduction motor 37 and drives the motor to center, thereby preventing the motor from rotating or shifting during operation, and accurately controlling the vegetables to be sorted to reach the preset shooting area.

[0071] In one embodiment, the food-grade transparent conveyor belt 91 is supported by the left bearing seat 51, the right bearing seat 58 and the left bearing 48, the right bearing 55, thereby ensuring that the food-grade transparent conveyor belt 91 runs smoothly under the drive of the main roller 23.

[0072] Preferably, sealing grooves are provided on the left bearing seat 51 and the right bearing seat 58 for installing a seal 62 to achieve dustproof and waterproof functions and protect the left bearing 48 and the right bearing 55 from the influence of the external environment.

[0074] Use a transparent conveyor device to transport the vegetables to be sorted;

[0075] The front image data of the vegetables to be sorted are obtained by an upper shooting module arranged above the food-grade transparent conveyor belt;
