Product Details

Product introduction:

YMJ-P (computer version) photographic leaf area meter consists of image acquisition equipment and image processing software. It uses the company's newly developed image recognition software. According to leaf contour feature extraction, graphic-to-object conversion, edge detection and other technologies, it can vividly and quickly obtain the measured leaf area, circumference, number of wormholes and other parameters. Compared with traditional leaf area, it has faster and simpler measurement, more vivid and objective results, diverse data and greatly reduces the errors caused by human operation.
