Food comparison photo taking device

Abstract

A photographic device for comparing food ingredients is characterized by comprising a housing, a light-diffusing plate, a light source box, and a camera gimbal. The inner cavity of the housing forms a photographic platform, the bottom wall and side walls connected to the bottom wall of which are coated with a reflective coating. The light-diffusing plate is located within the photographic platform and close to it. The light source box is located on the light-diffusing plate and emits light to the photographic platform. The camera gimbal is mounted on the housing and positioned at the port of the photographic platform. The determination of the photographic platform, combined with the light-diffusing plate, ensures that light is evenly projected onto the photographic platform (i.e., the shooting area). The reflective coating inside the photographic platform ensures consistent internal reflection of the light source. When the light source box illuminates the area, the brightness of the light source is much higher than that of the ambient light, so the photographing process is not affected by ambient light.

Description

Technical Field

[0001] This utility model relates to a photographing device, and more particularly to a photographing device for comparing food ingredients before and after. Background Technology

[0002] Currently, when taking before-and-after photos of food ingredients to perform comparative analysis, the method typically involves direct shooting in a standard light source colorimetric light box, without a dedicated photographic device. This has the following drawbacks:

[0003] First, when taking photos of food, changes in ambient light can cause the same food to appear completely different in photos taken at different times.

[0004] Secondly, the shooting position and angle may change. The first shooting position and the second shooting position are different, making it impossible to see the difference between the two.

[0005] Third, application scenarios: It can be used to photograph the differences between food and fruit before and after storage in a refrigerator or similar container, such as the changes that occur when an apple is stored in the refrigerator for seven days. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a food comparison photo taking device with high consistency in the shooting scene, in view of the above-mentioned technical status.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problem is a food comparison photo taking device, characterized by comprising:

[0008] The box has an inner cavity area that forms a photographing platform. The bottom wall and the side wall connected to the bottom wall of the photographing platform are both coated with a reflective coating.

[0009] A light-diffusing plate is installed on the top wall of the aforementioned photography platform.

[0010] The light source box is located within the photographing platform and near the aforementioned light-diffusing plate; and

[0011] The camera gimbal is mounted on the aforementioned housing and located at the port of the photography platform.

[0012] Furthermore, the light source box is equipped with a D65 standard colorimetric light source module, a D50 standard colorimetric light source module, and a TL84 standard colorimetric light source module.

[0013] Preferably, the reflective coating is a warm white coating.

[0014] Furthermore, the camera gimbal is mounted on a mobile platform, which can move laterally and move up and down relative to the camera platform.

[0015] The preferred configuration of the lateral translation structure is as follows: a first guide rail is provided horizontally on the port of the camera platform, a first locking mechanism is movably mounted on the first guide rail, and the moving platform is mounted on the first locking mechanism.

[0016] The first locking mechanism may include a first locking block and a first locking member disposed on the first locking block, wherein the first locking member can lock the first locking block onto the first guide rail.

[0017] The preferred configuration of the lifting structure is as follows: a second guide rail is provided on the first locking block, and a second locking mechanism is provided on the moving platform. The second locking mechanism can lift the second guide rail.

[0018] The second locking mechanism may include a second locking block and a second locking member disposed on the second locking block, the second locking member being able to lock the second locking block onto the second guide rail.

[0019] Preferably, there are two second guide rails arranged in parallel and spaced apart, and a second locking mechanism is provided at both ends of the moving platform. The camera gimbal is located in the middle of the moving platform.

[0020] Compared with existing technologies, the advantages of this invention are as follows: the precise positioning of the shooting platform, combined with a light diffusion plate, ensures uniform light projection onto the shooting platform (i.e., the shooting area). The interior of the shooting platform uses a reflective coating to guarantee consistent internal reflection of the light source. The brightness of the light source is significantly higher than the ambient light when illuminated by the light box, thus preventing interference from ambient light during shooting. With a consistent and defined shooting scene and lighting, the influencing factors on the food's appearance before and after shooting are reduced, facilitating a clear comparison of the changes in the food.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-4As shown, the food comparison photo taking device in this embodiment includes a box 1, a light diffusion plate 21, a light source box 2, and a camera gimbal 5.

[0028] The inner cavity of the housing 1 forms a photographic platform 11. The bottom wall and the side wall connected to the bottom wall of the photographic platform 11 are both covered with a reflective coating 12. In this embodiment, the reflective coating 12 is a warm white coating. A light diffusion plate 21 is disposed on the top wall of the photographic platform 11.

[0029] The light source box 2 is located inside the photography platform 11 and close to the light diffusion plate 21; the light source box 2 contains three standard colorimetric light source modules: D65, D50, and TL84.

[0030] The camera gimbal 5 is mounted on the housing 1 and located at the port of the photography platform 11. Specifically, in this embodiment, the camera gimbal 5 is mounted on the moving platform 4, which can move laterally and move up and down relative to the photography platform 11.

[0031] The housing 1 is provided with a first guide rail 31 in the horizontal direction at the port of the photo booth 11. The first locking mechanism 6 is provided on the first guide rail 31 and can move laterally. The moving platform 4 is provided on the first locking mechanism 6.

[0032] Combination Figure 3 and Figure 4 As shown, the first locking mechanism 6 includes a first locking block 61 and a first locking member 62 disposed on the first locking block 61. The first locking member 62 can lock the first locking block 61 onto the first guide rail 31. The first locking block 61 is provided with a second guide rail 32, and the moving platform 4 is provided with a second locking mechanism 7. The second locking mechanism 7 can move up and down on the second guide rail 32. The second locking mechanism 7 includes a second locking block 71 and a second locking member 72 disposed on the second locking block 71. The second locking member 72 can lock the second locking block 71 onto the second guide rail 32.

[0033] In this embodiment, both the first locking member 62 and the second locking member 72 are locking screws, and the first locking block 61 and the second locking block 71 respectively have locking holes through which the first guide rail 31 and the second guide rail 32 pass.

[0034] In this embodiment, the first guide rail 31 consists of two parallel rails arranged at intervals, and the second guide rail 32 also consists of two parallel rails arranged at intervals. The two ends of the moving platform 4 are provided with a second locking mechanism 7, and the camera gimbal 5 is located in the middle of the moving platform 4.

[0035] like Figure 5 As shown, in the working state, the camera 10 is mounted on the camera gimbal 5 and can take pictures at any time. The camera 10 can take pictures at fixed points in the up, down, left and right directions along with the camera gimbal 5.

[0036] When taking photos, the brightness of the light source box is far higher than that of the ambient light, so the shooting will not be affected by ambient light. This eliminates the shortcomings of existing systems where the light from above, below, left, right, and rear is blocked by the shooting platform structure, and the external light source can only enter from the front. The first and second locking mechanisms of the camera are fixed at one point, so the camera position is fixed before and after taking photos, allowing for comparison before and after shooting.
