1、 Purpose:
Used for plant ring analysis, leaf area analysis, lesion area analysis, insect damaged leaf area analysis, leaf color analysis, crop canopy analysis, etc.

2、 Main technical indicators
1. Equipped with a mid-range FileScan 1860XL high-speed scanner with optical resolution of 3600 dpi × 1800dpi and A3 format. A large depth of field 12 million pixel camera with autofocus, a 5V mobile power adjustable ultra-thin backlight board that can provide outdoor backlight illumination for 3 hours (maximum measurement area 380 * 265mm). It has the characteristics of automatic image correction and automatic measurement calibration.
2. Measurement and analysis of plant leaves:
(1) One click photography can be used to measure the area of live leaves in the wild.
(2) It can automatically analyze and calculate leaf area in large quantities. Analyze blades as small as 1mm ^ 2, with an analysis error of less than 0.5% and an analysis time of less than 2 seconds during measurement.
(3) It is possible to simultaneously analyze the leaf area, perimeter, maximum leaf length, maximum leaf width, rectangularity, concavity convexity ratio, sphericity, shape factor, lesion area, wormhole leaf area, number of wormholes, insect damaged leaf area (including analyzing the area of severely insect damaged leaves on more than 2/3 of the leaves), as well as parameters such as leaf holes, shape factor, number of serrations, petiole length and width of a single leaf, and mark the edges of the leaves for accuracy verification.
(4) It can measure the relative chlorophyll content or "greenness" of multiple plants and analyze leaf color (with colorimetric characteristics according to the Royal Society of Gardens RHS color chart 2015 edition).
(5) Can analyze crop canopy.
(6) Interactively measure various dimensions and angles related to plants.
3. Tree ring analysis:
(1) It can automatically read the number of annual rings, average width of each ring, width of early and late wood, tangential angle and area of each ring.
(2) It can automatically divide the boundaries of tree rings, early wood boundaries, late wood boundaries, and identify very narrow tree rings. It can interactively delete fake rings, insert broken rings, and automatically generate an analysis chronology.
(3) With the option of 'Fine' analysis, it can automatically analyze annual rings with a width of ≤ 0.2mm, and the measurement data obtained from the analysis has the ability to further perform cross dating and data analysis processing.
(4) Calculate the total area of the tree disk and analyze the sapwood area of the wood.
