Root system analyzer

I. Product Overview

The HD-GX01S photographic plant root analysis system is used for rapid imaging and multi-parameter, batch-wise automatic analysis of washed root samples with a diameter of 0.5 mm and above. The complete system consists of an overhead imaging device, PC-based analysis software and a computer (supplied by the user). Its imaging speed is about 20 times faster than that of scanner-type systems.

II. Key Performance Specifications

1. Equipped with an autofocus 22-megapixel colour imaging device. The maximum effective analysis area is 297 mm × 420 mm, which makes it particularly suitable for fast automatic measurement and analysis of roots 0.5 mm in diameter and above.

2. Measurable parameters:

(1) Total root length

(2) Branching frequency

(3) Mean root diameter

(4) Median root diameter

(5) Maximum diameter

(6) Total root surface area

(7) Total projected area

(8) Total root volume

(9) Root tip count

(10) Fork count

(11) Overlap count

(12) Root diameter class distribution parameters

(13) User-defined diameter classes at unequal intervals, with automatic measurement of the length, projected area, surface area and volume of each class together with their distribution parameters

(14) Root colour analysis, outputting the diameter, length, projected area, surface area and volume of roots in different colours

(15) Root topology analysis, automatically determining the number of connections and relationship angles; any single root segment can also be analysed separately for length, area and volume, and the parameters of any diameter class of a marked root system can be displayed individually (user-definable at unequal intervals)

(16) Correction of root forks, trimming, merging and connection, with undo support, so that a 100% correct result can be obtained quickly

(17) Automatic determination of the root fractal dimension by the box-counting method; root nodule counting is also available to objectively quantify the contribution of rhizobium

(18) Fully automatic batch root analysis with batch saving: all data can be summarised in one table, or the detailed data of each root system can be saved individually

(19) Gravitropic angle analysis and horizontal angle analysis for extraction of analytical features

(20) All analysed images, distribution maps and result data can be saved and exported to Excel; marked analysis images can also be output

(21) Cloud platform support: analysis data can be stored in the cloud and viewed at any time and anywhere

(22) Built-in bilingual Chinese/English display with one-key switching

III. System Requirements

1. A computer is required. Recommended configuration: a brand-name PC (Intel Core i5 9th generation or above / 16 GB memory / 24-inch colour monitor / wireless network card / at least four USB 2.0 ports, running a full version of Windows 10 Professional or Enterprise).

2. The software is compatible with Windows 10 and above.
