Aoda YMJ-C Android system Ingelligent leaf area meter

YMJ-CHA3 intelligent leaf area meter adopts advanced image processing technology. By taking photos of plant leaves to obtain leaf images, the software can automatically calculate leaf area, circumference, leaf length, leaf width, number of wormholes, etc., and display them on the same screen. It has the characteristics of high intelligence and simple operation. The intelligent leaf area measuring instrument can be widely used in field crop leaf area measurement in the agricultural field.

Functional features

1. The Android system has the characteristics of simple operation, humanized application, intelligence and upgradeability.

2. Full-color touch screen: 11-inch high-definition full-color touch screen, 13 million pixels. After taking photos, the software automatically calculates leaf area, circumference, leaf length, leaf width, number of wormholes and displays the results on the same screen.

3. The intelligent leaf area meter is equipped with two shooting background boards: the large backlight board is used with the pressure plate for more accurate analysis; the small board is easy to hold and is more suitable for outdoor live measurement.

4. Powerful storage function, with a built-in 128G memory card, which can store a large number of pictures and data.

5. Various analysis methods: single leaf can be analyzed, or multiple leaves can be analyzed at the same time

6. Diversified data viewing: data can be stored, reports can be viewed, and Excel tables can be exported to computers or uploaded to servers via WiFi. Data statistics and intelligent analysis.

7. With manual correction function, it can perform cutting, repairing, automatic petiole cutting, color analysis area selection and other functions to ensure high accuracy of measurement results.

8. Multiple algorithms are optional: there are three algorithms: general, dark, and light. You can choose the appropriate algorithm according to the color of the leaf to ensure accuracy.
