Leaf area meter

Instrument Introduction:

The BK-YMJ1 intelligent photographic leaf area measurement system consists of an image acquisition instrument and a tablet equipped with self-developed software. It adopts the area measurement algorithm accumulated by our company for many years, and based on technologies such as leaf contour feature extraction, graphic object conversion, edge detection, etc., it can quickly and vividly obtain parameters such as the measured leaf area, circumference, and number of wormholes. Compared to traditional leaf area, it has the advantages of faster and more convenient measurement, more vivid and objective results, diverse data, and greatly reduces errors caused by human operation.

instrumentFeatures:

The host is7Inch tablet, using Android system, with simple operation and easy application upgrade.

Diversified data viewing: data can be stored, viewed in reports, and exported to computers orWiFiUpload to the server.

Equipped with manual correction function, It can be cut, repaired, or trimmed according to the blade contour to ensure high measurement accuracy.

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

The acquisition device comes with a controllableLEDAnd equipped with customized transparent anti reflective pressure plates, the leaves can be measured flat and without shadows.

The data is saved in the form of images and can be used forexcelForm upload.

After taking photos, the results are automatically measured, avoiding the errors caused by traditional manual operation of leaf area and making the measurement more intelligent.

Fast measurement speed, area measurement time less than1In seconds.
