Overview
Measurement accuracy of plant image analysis using the annual ring analyzer parameters (determined by the scanner and can be partially corrected by software): X direction ≤± 0.5%, Y direction ≤± 0.25%; Reproducibility error in length measurement
Product Details
Performance characteristics of annual ring analyzer
1. Automatic impurity removal: Based on differences in size and other aspects, automatic impurity removal is performed.
2. Manual assisted correction: The image can be zoomed in and out and observed locally, and mouse area selection statistics can be achieved.
3. Auxiliary measurement function:
Size calibration: With built-in calibration function, semi-automatic size calibration can be achieved, and XY directions can be calibrated and corrected separately;
Length measurement: With the function of following the magnifying glass, accurate measurement can be made by dragging with the mouse;
4. Data report export: The analysis results can be exported to an Excel spreadsheet for archiving and statistical purposes. It can also output analysis markers for publication purposes.
1) Automatically read the number of tree rings
2) Average width of each annual ring
3) Width of early and late wood
4) Tangential angle and area of each annual ring
5) It can automatically divide tree ring boundaries, early wood boundaries, late wood boundaries, and identify very narrow tree rings
6) It can interactively delete pseudo annual rings, insert broken annual rings, and automatically generate internationally recognized analysis chronologies. The measurement data obtained through analysis has the ability for further cross dating, data analysis and processing
7) It has the characteristics of temporary storage and loading of annual ring chart data for continuous analysis and comparison in the future. The "software body mirror" feature with precise analysis. There is a path endpoint [adsorption] positioning feature, which allows for the disconnection, deletion, addition, and editing of unsatisfactory analysis paths, as well as the ability to save analysis result graphs. Adjusting the angle on the graph has a following characteristic, and when drawing the path, you can 【 Cancel 】 (right-click menu and click 【 Cancel 】 or directly press 【 Del Delete 】 key)
8) It can directly analyze ultra large format annual ring images with ultra-high precision scanning up to 20000 million pixels (200 million pixels). It has the ability to automatically analyze extremely fine tree rings with a width of less than 0.2mm.
9) Can save or read images in TIFF, BMP, PNG, JPEG standard formats
