Examples
An image collection box 100 for quantitatively evaluating color and luster of dry tea is disclosed, which is shown in fig. 1 and comprises a housing 110, wherein an image collection cavity 120 is formed inside the housing 110.
In this embodiment, the image capturing box 100 is a rectangular parallelepiped, and has a size of 30cm by 50cm, so that the whole size is small and flexible, and the image capturing box is very convenient to carry. As shown in fig. 1 and 2, a sample groove 121 for placing a dry tea sample is disposed at the bottom of the image collection cavity 120, a camera 111 facing the sample groove 121 and a light source 112 for light supplement are disposed on the top wall of the image collection cavity 120, and a diffuse reflection layer 113 made of white frosted material is covered on the cavity wall of the image collection cavity 120. When the image is collected, the dry tea sample is firstly paved in the sample groove 121, and then the image is shot through the camera 111. The height of the image capturing chamber 100 fixes the distance for capturing images, the relatively sealed capturing environment and the single light source 112 avoid the influence of ambient light on the images, and the diffuse reflection layer 113 further avoids the influence of reflected light on the wall of the image capturing chamber 120 on the captured images.
Further, as shown in fig. 2, the camera 111 is located at the center of the top wall, and the light source 112 is disposed around the light source 112 along the edge of the top wall. Such a distribution of light sources 112 may result in a more uniform illumination of the dry tea sample, such that the level of illumination is substantially the same throughout the dry tea sample. Optionally, the light source 112 is a white soft light source 112. The white soft light source 112 has less influence on the original hue of the image, and can reflect the real color of the dry tea sample.
In addition, the image collection box 100 comprises a drawer 130, the image collection chamber 120 comprises a front wall 1101, a rear wall 1102 and a pair of side walls 1103 positioned between the front wall 1101 and the rear wall 1102, the lower end of the front wall 1101 is provided with an opening 1104 for the drawer 130 to access, the sample slot 121 is positioned in the drawer 130, and the inner wall of the drawer 130 is covered with a diffuse reflection layer 113 made of white frosted material. The design of the drawer 130 type is adopted, so that the dry tea sample can be taken and placed more conveniently. In actual use, the drawer 130 is firstly pulled out, the dry tea sample is added into the sample groove 121 until the dry tea sample is fully paved in the sample groove 121 by a thin layer, and then the drawer 130 is pushed into the image acquisition cavity 120. On the walls of the sample well 121, corresponding graduations may be marked to indicate the thickness of the spread of the dry tea sample, keeping the thickness of the sample substantially uniform for each pattern acquisition.
Further, as shown in fig. 1 and 2, a plurality of anti-slip bumps 131 are convexly disposed at the bottom of the sample groove 121, and the plurality of anti-slip bumps 131 are uniformly distributed at the bottom of the sample groove 121. The anti-slip bumps 131 can increase friction, reduce the slip of the dry tea sample during the drawing process of the drawer 130, and maintain the effect of tiling.
Optionally, the receiving groove 114 is disposed on both the rear wall 1102 and the pair of side walls 1103, and the drawer 130 may be embedded in the receiving groove 114. The drawer 130 is slidably connected to the receiving groove 114, and the receiving groove 114 can limit the sliding direction of the drawer 130. When the drawer 130 slides into position, the inner side walls 1103 of the drawer 130 are flush with the front wall 1101, the rear wall 1102 and the pair of side walls 1103, respectively, so as to avoid blocking and reflecting light.
The handle 132 is disposed on the outside of the drawer 130, and the handle 132 is located on the side of the drawer 130 away from the rear wall 1102. The handle 132 may be held by an operator to pull the drawer 130 out. The top of the image collection box 100 is provided with a handle 115, and the handle 115 can be conveniently carried, thereby increasing the portability of the image collection box 100.
Further, as shown in fig. 1 and 2, the outer wall of the image capturing box 100 is provided with a display 116, and the display 116 is electrically connected to the camera 111. The image collected by the camera 111 can be displayed on the display 116, which is convenient for the operator to view.
In addition, the image capturing box 100 further comprises a storage battery for supplying power to the display 116, the camera 111 and the light source 112, and the storage battery is electrically connected with the display 116, the camera 111 and the light source 112. The image acquisition box 100 can supply power to the external power supply, but the portability of the image acquisition box can be further improved by adding the storage battery, so that the image acquisition box is convenient to sample at any time and any place.
On the basis, the image acquisition box 100 can be additionally provided with a data processing module, image cutting software and operation software which are independently researched and developed by the inventor are input into the data processing module, the acquired image can be cut into sample wafers with uniform resolution, hue, saturation and darkness of each pixel point in the sample wafers are analyzed, a color and luster quantification conclusion of the dry tea sample is obtained, and the conclusion can be directly displayed through the display screen 116 and can be visually seen by an operator.
To sum up, the utility model provides an image acquisition box 100 for dry tea color and luster quantitative evaluation, it includes casing 110, casing 110 is inside to be formed with image acquisition chamber 120, and image acquisition chamber 120's bottom is provided with the sample cell 121 that is used for placing dry tea sample, and image acquisition chamber 120's roof is provided with just to the camera 111 of sample cell 121 and the light source 112 that is used for the light filling, and image acquisition chamber 120's chamber wall covers the diffuse reflection layer 113 that has white dull polish material. When image acquisition is performed, the height of the image acquisition box 100 fixes the image shooting distance, the relatively sealed shooting environment and the single light source 112 avoid the influence of ambient light on the image, and the arrangement of the diffuse reflection layer 113 further avoids the influence of reflected light on the wall of the image acquisition cavity 120 on the shot image. The whole image collection box 100 is simple in structure, convenient to use and carry, can standardize an image collection program of a dry tea sample, and reduces the influence of environmental differences on quantitative evaluation conclusions.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
