Photographic leaf area meter YMJ-P2

Product Introduction:

The YMJ-P2 photographic leaf area meter (flat version) consists of an image acquisition device and image processing software. It uses our company's newly developed image recognition software to extract leaf contour features, convert graphics to physical objects, and perform edge detection. It can quickly and vividly obtain parameters such as leaf area, circumference, and number of wormholes, and can measure the leaves in sections. The system will automatically merge two images and comprehensively analyze each parameter. 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.

Technical parameters:

Measurement parameters: leaf area, perimeter, maximum leaf length, maximum leaf width, circularity, aspect ratio, sphericity, shape factor, number of wormholes, wormhole area, etc

Scope of application: Various common leaves that are complete or contain wormholes

Measurement range: 1-600 square centimeters

Maximum leaf length: 0-290mm

Maximum leaf width: 0-210mm

Measurable wormhole range: not less than 0.1 square centimeters

Measurement accuracy: 2%

Stability: Change within one year<± 2%

Response time: 50ms

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

Analysis data export: The analysis image results can be saved and automatically generate a total report. The statistical analysis results can be output to an Excel spreadsheet.

Cloud platform data transmission: Data can be uploaded to the cloud platform, and historical data can be retrieved according to any time period and leaf category. The measurement time leaf area, circumference, maximum leaf length, maximum leaf width, roundness, concavity convexity ratio, sphericity, shape coefficient, number of wormholes, wormhole area, and other data can be viewed. Bar chart analysis can be performed on different parameters, and data can be exported in EXCEL spreadsheet format. Data can be displayed according to the selected time period, analyzed in tables, bar charts, and downloaded online.

Automatic update: The software has an online automatic update function, which automatically detects new versions every time it enters the system. Users can choose to update or update the system at other times.
