YMJ series portable leaf area meter is a newly developed product. It is a portable instrument that is easy to use and can work in the field. It can accurately, quickly and non-destructively measure the leaf area and related parameters of the leaf, and can also measure the area of the picked plant leaves and other sheet-like objects. It is widely used in agriculture, meteorology, forestry and other sectors.
The instrument can directly measure the length, width and area of the leaf, and integrates the GPS positioning system, and adds the RS232 interface, which can import the measurement data and positioning information into the computer at the same time, which is convenient for researchers to further process the data.
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.
YMJ-S leaf image analyzer adopts an open architecture system and can be freely combined into a field portable, laboratory type and other scanning individual area measurement instruments. The instrument uses a calibrated image capture device to obtain high-quality leaf images and uses professional software to accurately analyze and calculate leaf area and related parameters. It is widely used in plant physiology, plant ecology, plant pathology, agronomy, horticulture and forestry, and can be used for morphological and plant pathology research.
