Product details

Product Introduction:

The photographic leaf area meter (computer version) consists of image acquisition equipment and image processing software, using our company's newly developed image recognition software. Based on technologies such as leaf contour feature extraction, graphic object conversion, edge detection, etc., it can vividly and quickly obtain parameters such as measured leaf area, circumference, and number of wormholes. 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.

Main 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

Segmented measurement of large blades: It is possible to measure blades that exceed the range in segments, and the system will automatically merge two images and comprehensively analyze various parameters

Measurable wormhole range: not less than 0.1 square centimeters

Measurement resolution: Area: 0.001cm ² Length and width: 0.01cm

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

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

Stability: Change within one year<± 2%

Average response time: 100ms

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

The software is only compatible with Windows 7 and above systems. It is recommended to use Windows 10 system

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, perimeter, maximum leaf length, maximum leaf width, rectangularity, concavity convexity ratio, sphericity, shape coefficient, number of wormholes, wormhole area, and other data can be viewed. Line chart analysis can be performed on different parameters, and data can be exported in Excel format. Data can be displayed according to the selected time period, analyzed in tables, line charts, and downloaded online.
