Abstract
Description
Technical Field
[0001] This utility model relates to the field of physical detection technology in flue-cured tobacco production, and in particular to a device for assisting in the acquisition and measurement of tobacco leaf images in the field. Background Technology
[0002] The maturity of tobacco leaves at field harvest is closely related to the appearance, chemical quality, smoking quality, and safety of cured tobacco leaves. Accurately determining the maturity of tobacco leaves at field harvest guides timely harvesting, significantly improving tobacco quality and industrial usability. Currently, Henan Tobacco has developed intelligent field maturity recognition technology for tobacco leaves. By capturing images using mobile software, the system can accurately determine the maturity of tobacco leaves at field harvest, guiding farmers to harvest and cure them at the appropriate time, thereby improving the quality of cured tobacco leaves.
[0003] The tobacco plants in the field are large, with leaves arranged in whorls along the axis. Currently, when using mobile phone software to identify the maturity of tobacco leaves in the field, other leaves are often captured in the photo while one leaf is being photographed, causing interference. To reduce errors, one person needs to push aside the leaves other than the one being photographed while another takes the picture. Furthermore, cluttered backgrounds such as soil can also affect the software's judgment, hindering accurate determination of the maturity of tobacco leaves in the field. Measuring the length and width of the tobacco leaves requires a separate measuring tape, reducing data collection efficiency.
[0004] Therefore, there is an urgent need for a device that can be operated by a single person, reduces background interference, and integrates measurement functions. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a device for assisting in the acquisition and measurement of tobacco leaf images in the field, which solves the problems of background interference, complex operation and low measurement efficiency, and allows a single person to independently complete the shooting and identification of tobacco leaves in the field.
