Photographic leaf area meter (YMJ-P2)

Product Introduction

Photographic leaf area meter

The intelligent photo taking leaf area measurement system consists of an image acquisition instrument and a flat panel loaded 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, and edge detection, it can vividly and quickly obtain parameters such as the measured leaf area, perimeter, and number of wormholes. Compared to traditional leaf area, it has the advantages of faster and simpler measurement, more vivid and objective results, diverse data, and greatly reduces errors caused by human operations.
