Photographic leaf area measuring instrument YMJ-P2

Photographic leaf area measuring instrument

Product Description:

YMJ-P2 photographic leaf area meter (plate version) consists of image acquisition equipment and image processing software, using the company's newly developed image recognition software, according to the leaf contour feature extraction, graphic physical conversion, edge detection and other technologies, can image and quickly get the measured leaf area, perimeter, the number of wormholes, and other parameters, and can be measured in sections of the leaf, the system will automatically merge the two pictures and comprehensively The system will automatically merge the two images and analyse the parameters. Compared with the traditional leaf area, it is faster and easier to measure, the result is more objective, the data is diversified and the error brought by human operation is greatly reduced.

Technical parameters:

Measurement parameters: leaf area, perimeter, maximum leaf length, maximum leaf width, roundness, concavity-convexity ratio, sphericity, shape coefficient, number of wormholes, area of wormholes, etc.

Scope of application: all kinds of complete or containing wormholes of common leaves

Measuring range: 1-600cm2

Maximum leaf length: 0-290mm  

Maximum leaf width: 0-210mm

Measurable wormhole area: not less than 0.1cm2

Measurement accuracy: 2%

Stability: <±2% change within one year

Response time: 50ms

Analysis data export: analysis image results can be saved, automatically form a total report, statistical analysis results can be output to Excel table.

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, you can view the measurement time leaf area, perimeter, maximum leaf length, maximum leaf width, roundness, concavity-convexity ratio, sphericity, shape coefficient, the number of wormholes, the area of wormholes, etc., you can do histogram analysis of different parameters, support for the data in the form of EXCEL table export, you can select the time period to display the data, support data in the form of Excel table, you can select the time period to display the data, support data in the form of Excel table. Support data to be exported in the form of EXCEL table, data can be displayed according to the selected time period, support data to be analysed in tables, bar charts, etc. and downloaded online.

Automatic update: The software has online automatic update function, every time you enter the system will automatically detect the new version, the user can choose to update or choose to update the system at other times.
