LAM-C camera type leaf area meter

Introduction:

Plant leaves are important organs for plants to synthesize organic matter for photosynthesis. The size of the leaf area directly affects the yield of crops to a certain extent. Therefore, it is convenient and accurate to establish a method for measuring leaf area. It is necessary to guide the research on crop physiological mechanism, agricultural production practice and formulating high-yield, high-quality and high-efficiency cultivation techniques. Positive meaning.

The LAM-C photo-type leaf area meter is composed of an image acquisition instrument and a flat plate loaded with self-developed software. It adopts the area measurement algorithm accumulated by the company for many years, and can image according to the features of blade contour feature extraction, graphic object transformation and edge detection. Quickly obtain parameters such as the measured leaf area, perimeter, and number of wormholes. Compared with the traditional leaf area, it has faster and easier measurement, more objective results, more diverse data and greatly reduced errors caused by human operation.

Features:

1. The host is a 7-inch tablet with Android system, which is easy to operate and easy to upgrade.

2. Data viewing diversification: data can be stored, reports can be viewed, and data can be exported to a computer or WiFi to be uploaded to a server.

3. With manual correction function, it can cut, repair and cut the blade handle according to the contour of the blade to ensure high precision.

4. After taking a picture, the system can automatically calculate the area, perimeter, leaf length, leaf width, shape factor, number of wormholes and display on the same screen.

The collector comes with controllable LEDs and a custom transparent, anti-reflective platen that allows the leaves to be measured in a flat, unshaded condition.

5. The data is saved as a picture, and the data can be uploaded in excel form.

6. Automatically measure the result after taking pictures, avoiding the error caused by the artificial operation of the traditional leaf area, and the measurement is more intelligent.

7. The measuring speed is fast, and the area measuring time is less than 1 second.
