1、 Purpose:
Used for quick and convenient analysis and measurement of plant leaf area in situ in the field.

2、 Main technical indicators
1. Equipped with a portable power bank auxiliary backlight board, it can provide outdoor backlight illumination for 3 hours. Single shot photographyMaximum measured blade area 520 * 225mmAutomatic calibration and automatic image correction.
2One click operation for photography and analysisIt can analyze parameters such as leaf area, perimeter, aspect ratio, maximum leaf length, maximum leaf width, rectangularity, concavity convexity ratio, sphericity, shape factor, number of wormholes, wormhole area, etc. of multiple leaves, and mark the edges of the leaves for accuracy verification.
3Can analyze blades as small as 1mm ^ 2The measurement and analysis time is less than 5 seconds.
4. Automatically mark each blade independently and save the image, and output the analysis results.
5. It can automatically measure the length, width, and projected area of ordinary seeds such as rice, wheat, and melon seeds that do not collide with each other.
6. The size range and accuracy of measuring blades are as follows:
(1) Measurement range of blade length for a single photo: 0-520mm（Support multiple image stitching）The leaf width is 0-225mm.
(2) The measurement error of blade length and width for a single photo is less than ± 1%, and the measurement error of blade length and width for splicing is less than ± 2%.
(3) The measurement range of the aspect ratio of the blade is not limited. The measurement error of the aspect ratio of the blade taken in a single photo is less than ± 2%, and the measurement error of the aspect ratio of the spliced blade is less than ± 2%.
(4) The measurement range of blade circumference is 0-1200mm; the measurement error of blade circumference for a single photo is less than ± 2%, and the measurement error of blade circumference for splicing is less than ± 3%.
(5) Blade area measurement range: 0-10000000mm ^ 2; The measurement error of blade area for a single photo is less than ± 1%, and the measurement error of blade area for splicing is less than ± 2%.

3、 Standard configuration
1. 1 12V portable power bank
2. 1 set of 12V long backlight panel and blade pressing plate
