Digital Leaf Area Meter YMJ-C

Digital Leaf Area Meter YMJ-C

The intelligent leaf area measurement system is also called a leaf area scanner. The intelligent leaf area measurement instrument consists of a flat panel with embedded software. Using advanced image processing technology, it is a software designed comprehensively according to leaf feature extraction, space transformation, edge detection principle, morphology and other technologies.

Features:

1、Android system has the characteristics of simple operation, humanised application, intelligent and upgradable.

2, Full-colour touch screen: 11-inch high-definition full-colour touch screen, 13 megapixels, the software automatically calculates the leaf area, perimeter, leaf length, leaf width, number of wormholes and displays the results on the same screen after taking photos.

3, equipped with two shooting background plate: large backlight plate with the pressure plate to use, more accurate analysis; small plate easy to hold, more suitable for outdoor live measurement use.

4, powerful storage function, comes with 128G memory card, can store a large number of pictures and data.

5、Diversified analysis methods: single blade can be analysed, and multiple blades can be analysed at the same time.

6, data view diversification: data can be stored, you can view the report, you can also export Excel tables to the computer or WiFi uploaded to the server. Data statistics, intelligent analysis.

7, with manual correction function, can be cut, repair, automatically cut the petiole, select the colour analysis area and other functions to ensure that the measurement results of high precision.

8, a variety of algorithms can be selected: there are three kinds of algorithms: universal, dark and light, according to the leaf colour to choose the appropriate algorithm, to ensure the accuracy.
