Product Details

Product introduction:

The YMJ-P camera leaf area meter (computer version) consists of image acquisition equipment and image processing software. It uses the company's newly developed image recognition software. Based on leaf contour feature extraction, graphic-to-object conversion, edge detection and other technologies, it can visually and quickly obtain the measured leaf area, perimeter, 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.

Main technical parameters:

Measurement parameters: leaf area, perimeter, maximum leaf length, maximum leaf width, rectangularity, concavo-convex ratio, sphericity, shape coefficient, number of wormholes, wormhole area, etc.

Applicable scope: various common leaves with complete or wormholes

Measurement range: 1-600 square centimeters

Maximum leaf length: 0-290mm

Maximum leaf width: 0-210mm

Segmented measurement of large leaves: leaves exceeding the range can be measured in segments, the system will automatically merge two pictures and comprehensively analyze various parameters

Measurable wormhole range: not less than 0.1 square centimeters

Measurement resolution: Area: 0.001cm² Length, width: 0.01cm

Measurement accuracy: 1% (greater than 30cm²), 2% (less than 30cm²)

Host storage capacity: depends on the hard disk space of the host device, 1~3MB per group on average.

Stability: changes <±2% within one year

Average response time: 100ms

Application temperature: -30℃-80℃; relative humidity 0-100%

Cloud platform data transmission: data can be uploaded to the cloud platform, historical data can be retrieved according to any time period and leaf category, and data such as leaf area, circumference, maximum leaf length, maximum leaf width, rectangularity, concave-convex ratio, sphericity, shape coefficient, number of wormholes, wormhole area, etc. can be viewed at the measurement time. Histogram analysis can be performed on different parameters, and data can be exported in the form of EXCEL tables. Data can be displayed according to the selected time period, and data can be analyzed in the form of tables, histograms, etc., and downloaded online.
