Seed Analysis Instrument

The Seed Grading Analyzer consists of three components: a 16-megapixel high-resolution scanner, a backlighting unit, and a tablet equipped with embedded software. The backlighting unit utilizes high-brightness LED lamps, with its outer frame constructed from aluminum alloy.

The software employs advanced image processing techniques, incorporating distance transformation principles, morphology, convex hull detection, and other technologies to create a comprehensive embedded solution.

Primarily applied in agricultural fields for crop yield estimation and seed grading, the device captures images via the high-resolution scanner. The software automatically calculates seed count, area, perimeter, length, width, aspect ratio, and other metrics. It then automatically determines the thousand-seed weight based on the scale's recorded weight and seed count. Results are output in both tabular and graphical formats for easy user review and analysis.

Users can manually adjust seed counts to ensure accuracy, save data, review reports, and export data in Excel format. Alternatively, data can be uploaded via WiFi to the instrument's cloud-based data management system for intelligent statistical analysis.

The Seed Analyzer measures the quantity, thousand/hundred-seed weight, and average seed morphology (including length, width, aspect ratio, circumference, and area) of various smooth-surfaced grains. It employs image OCR recognition technology, image positioning, and spatial transformation techniques to rapidly identify seed counts and crop trait metrics.

• The Android system offers advantages such as simplified operation, user-friendly and intelligent applications, and upgradability.

• Built-in bilingual Chinese-English display with one-touch switching for seamless integration.

• Imaging Features: Equipped with a 16-megapixel color high-resolution scanner featuring auto-focus and an ultra-thin backlight panel. It automatically corrects camera image distortion and ensures uniform backlight distribution, effectively minimizing dimensional measurement errors.

• Backlighting System: Utilizes high-brightness LEDs driven by a power supply. Nano-optical light guides and reflective materials ensure clear illumination with no shadows on seeds. The aluminum alloy outer frame offers an aesthetically pleasing, durable, and distortion-resistant design.

• Seed analysis covers diameters from 0.5 to 20 mm. For rice seeds, viable grains and empty grains must undergo air-classification before separate counting and analysis to determine grain setting rate.

• Automatically measures individual shape parameters (length, width, aspect ratio, area, perimeter) for all types of adhered seeds. Measurement error for all seed dimensions ≤ ±0.1mm.

• Counting accuracy and target size: 1–2000 seeds/batch, counting error ≤ ±0.2%. Minimal manual monitoring ensures result accuracy. Thousand-grain weight analysis accuracy error: ≤±1mg.

• Includes sample record functionality; automatically calculates thousand-grain weight upon sample weight input. Analysis process features automated flat-plate control, delivering efficient, accurate, and user-friendly operation with one-button counting analysis and thousand-grain weight measurement.

• Data Export: Analysis images are savable, with automatic generation of summary reports. Statistical results export to Excel format. Supports online printing, data display by selected time periods, and analysis via tables/bar charts. Enables online download and printing.

• The seed grading system is supported by a cloud platform. Data can be uploaded to the cloud platform, allowing retrieval of historical data by any time period and seed category. Users can view measurement time, seed count, thousand-seed weight, average area, average perimeter, average length, average width, and seed image thumbnails. Bar chart analysis can be performed for different parameters.

• Automatic Updates: The software features an online automatic update function. Each time the system is accessed, it automatically checks for new versions. Users can choose to update immediately or schedule the update for a later time.
