Embodiment 1

[0025] (1) Select 2 pieces of orange-yellow grade 2 tobacco leaves from Zunyi City and Tongren City, Guizhou Province in 2019, and balance them for 3-4 days under the conditions of temperature (22±1)°C and relative humidity (60±3)%. content to 16%-18%.

[0026] (2) Open the cover of the scanner, place the blade on the platen glass with the front facing up and the back facing down, and close the cover; start the scanner, and make relevant settings in the scanning parameter setting dialog box, such as output type color, The resolution is 300dpi, the scan size is the entire scan area, the image format is JPEG, the file save path and file name, click the "Scan" button, after the scan is completed, the image file will be automatically saved to the specified folder. In this embodiment, the scanner may be a commercially available flatbed scanner with a maximum format of A3.

[0027] (3) Open the image with Photoshop software, execute the "file" - "open" command, pop up the open dial...

Abstract

The invention discloses a method for measuring tobacco leaf residual injury based on Photoshop software. The method comprises steps of S1, tobacco leaf pretreatment, pretreating to-be-detected tobaccoleaves to enable the moisture content of the tobacco leaves to be in a set period; S2, image acquisition, acquiring an image of the to-be-detected tobacco leaves; S3, acquiring a total pixel value ofthe to-be-detected tobacco leaves, acquiring a total pixel value of the to-be-detected tobacco leaves by utilizing a Photoshop software magnetic lasso tool, and recording a total pixel value as X; S4, acquiring a pixel value of a residual wound part, accurately selecting disease spots, withered parts or damaged parts on the to-be-detected tobacco leaves by utilizing a Photoshop software magneticlasso tool and a magic wand tool, reading a pixel value by utilizing a histogram, calculating a pixel value of the residual wound parts on the to-be-detected tobacco leaves, and recording the pixel value as Y; and S5, calculating the residual injury of the to-be-detected tobacco leaves, wherein the residual injury is equal to (Y/X)*100%. The method is advantaged in that the method is simple to operate, convenient and fast, has no influence on the tobacco leaves, can accurately and quantitatively determine a residual injury ratio of the tobacco leaves, and fills the blank of a tobacco leaf residual injury determination method.

Description

technical field [0001] The invention relates to a method for measuring tobacco leaf damage based on Photoshop software, and belongs to the technical field of tobacco leaf damage detection. Background technique [0002] The procurement of flue-cured tobacco is divided into grades according to seven appearance grade factors such as maturity, leaf structure, identity, oil content, color, length, and disability. Damage means that the tissue of the tobacco leaf is damaged (lesions, scorch), loses the strength and firmness of the silk, or the variegated color penetrates the back of the leaf, causing the tissue to be damaged and basically useless, including the appearance of tobacco leaves due to the increase of maturity. Lesions, focal edges and focal tips, expressed in percentage (%). The use of damage in tobacco leaf grading is based on the level of the grade. The percentage of the damage area to the total leaf area is used to control the damage of the grade. The damage cannot ...
