Online ConsultationProduct Introduction
The Photographic Leaf Area Meter (PC Version) consists of an image acquisition device and image processing software. Utilizing our newly developed image recognition software, it employs techniques such as leaf contour feature extraction, graphic-to-physical conversion, and edge detection to visually and rapidly obtain measured parameters including leaf area, perimeter, and insect damage counts. Compared to traditional leaf area measurement methods, it offers faster and simpler measurement, more vivid and objective results, diverse data, and significantly reduces errors caused by human operation.
Product Features
Cloud Platform Data Transfer: Data can be uploaded to the cloud platform, supporting export in Excel spreadsheet format. Data can be displayed for selected time periods and analyzed in tables, bar charts, etc., with online download capability.
View measurement data including leaf area, perimeter, maximum leaf length, maximum leaf width, rectangularity, concavity ratio, sphericity, shape coefficient, number of insect holes, and insect hole area. Perform bar chart analysis on various parameters.
Historical data can be retrieved by any time period and leaf category with simple operations.
Offers advantages including faster and simpler measurement, more vivid and objective results, diverse data types, while significantly reducing human operational errors.
