Description

Technical Field

[0001] This utility model relates to the field of tobacco leaf photography technology, and in particular to a box for photographing the front and back of a whole bundle of tobacco leaves. Background Technology

[0002] With the development of image processing technology and neural networks, accurate identification of fresh tobacco leaf quality is a crucial prerequisite for formulating curing processes and ensuring the quality of tobacco leaf curing in the tobacco agriculture field. Accurate and rapid tobacco leaf quality identification ensures the rational classification and curing of tobacco leaves, reduces the technical difficulty of tobacco leaf curing, and achieves the goals of improving quality and efficiency, reducing labor and costs, and increasing tobacco farmers' income. In current actual production, intelligent identification of fresh tobacco leaves mainly focuses on the image acquisition and identification of individual leaves, with less attention paid to whole bundles of tobacco leaves. Furthermore, in the image acquisition and identification of whole bundles of tobacco leaves, since the leaves are arranged in a staggered manner, the quality identification of whole bundles of tobacco leaves should fully consider the differences between the front and back images, and comprehensively judge the quality of tobacco leaves by combining the front and back images of whole bundles of tobacco leaves.

[0003] In the prior art, such as the Chinese utility model patent with announcement number CN221635007U, a tobacco curing barn loading auxiliary device based on tobacco quality identification is disclosed. It can use image processing components and weighing components to take into account the differences in curing characteristics caused by different growth and development of tobacco plants, and provide guidance for accurate tobacco loading. Although it solves the problem of poor loading effect and low curing quality caused by inaccurate tobacco quality identification in the prior art, there are still problems such as the influence of external light on the shooting effect during data collection, resulting in inaccurate shooting sampling, and only one side can be shot during shooting, instead of both sides at the same time, resulting in low efficiency of shooting both sides. Utility Model Content

[0004] The purpose of this utility model is to provide a camera box for photographing the front and back sides of a whole bundle of tobacco leaves, which can solve the problems in the current stage of fresh tobacco leaf quality identification, such as incomplete photography of both sides of the whole bundle of tobacco leaves and increased labor costs when the whole bundle of tobacco leaves needs to be flipped during photography.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a camera for photographing the front and back sides of a whole bundle of tobacco leaves, comprising a host computer, a camera housing, and image acquisition components that cooperate with the host computer. At least two image acquisition components are provided, symmetrically arranged within the camera housing. Each opening of the camera housing is provided with a light-shielding component. A movable tobacco hanging rod for hanging tobacco leaves is slidably arranged within the camera housing, located between the image acquisition components symmetrically arranged within the camera housing. The camera housing is also provided with a supplementary lighting component for supplementing light to the tobacco leaves.

[0006] Furthermore, the movable cigarette holder includes a rectangular frame, and the upper part of the rectangular frame is provided with a plurality of evenly distributed cigarette holders.

[0007] Furthermore, the cigarette holder is an L-shaped rod.

[0008] Furthermore, the shooting box is a frame-shaped frame with openings on both the front and back sides.

[0009] Furthermore, the rectangular frame is provided with two parallel sliding rods, which are respectively connected to the upper and lower sides of the rectangular frame. The shooting box is provided with a guide rail, and the guide rail is provided with grooves that cooperate with the sliding rods.

[0010] Furthermore, the light-shielding assembly includes a light-shielding cloth and a connecting shaft. One end of the light-shielding cloth is connected to the connecting shaft, and both ends of the connecting shaft are connected to light-shielding boxes, which are connected to the shooting box.

[0011] Furthermore, the connecting shaft is movably connected to the sunshade box, and the end of the connecting shaft extends out of the sunshade box and is connected to the circular steering wheel.

[0012] Furthermore, a guide rod is provided on the other end of the light-blocking cloth, and a guide groove is provided on the side of the opening of the shooting box. The end of the guide rod is slidably engaged with the guide groove.

[0013] Furthermore, the supplementary lighting assembly includes at least four symmetrically distributed supplementary lights, which are installed at the corners of the shooting box.

[0014] Furthermore, the image acquisition device is an industrial camera, which is connected to a bracket housed within the imaging chamber.

[0015] The beneficial effects of this utility model are as follows: By hanging whole bundles of tobacco leaves on a movable tobacco hanging rod, placing the movable tobacco hanging rod inside a camera box, and using a light-blocking cloth for light protection, this utility model, through at least two image acquisition units symmetrically distributed between the movable tobacco hanging rods and working in conjunction with a host computer, can photograph the tobacco leaves on the movable tobacco hanging rods and identify the quality of whole bundles of fresh tobacco leaves. This avoids subjective human judgment, improves the accuracy of identification, and enables the simultaneous acquisition of images of both the front and back sides of the whole bundle of tobacco leaves, improving acquisition efficiency and meeting the need for accurate and rapid identification of the quality of fresh tobacco leaves before curing. When acquiring and identifying whole bundles of tobacco leaves, both front and back images can be acquired at once, avoiding the need for manual flipping when acquiring front and back images, thus reducing labor and time costs.
