Intelligent testing system

1. Instrument Overview

The intelligent seed testing system consists of three parts: a 16 million high-speed scanner, a backlight device, and a tablet with embedded software. The backlight device uses a high-brightness LED light, and the outer frame is made of aluminum alloy. The software uses advanced image processing technology and is an embedded software designed based on distance transformation principles, morphology, convex hull detection and other technologies. The equipment is mainly used in field crop yield measurement and seed testing in the agricultural field. Through the photos taken by the high-speed scanner, the software automatically calculates the number of seeds, the area, circumference, length, width, aspect ratio and other data of the seeds, and automatically calculates the thousand-grain weight based on the weight obtained by the balance and the number of seeds; the results are output in the form of lists and graphics for users to view and analyze. This product can also manually correct the number of crop seeds to ensure counting accuracy, save data, and view data reports. Finally, the data can be exported in Excel format, or uploaded to the instrument cloud data management system via WiFi data to achieve data statistics and intelligent analysis.

2. Application

The intelligent seed testing system can measure the number, thousand/hundred-grain weight and average grain shape (including length, width, aspect ratio, perimeter and area) of various smooth-surfaced grains, and use image ORC recognition technology, image positioning, space conversion and other technologies to quickly identify the number of seeds and crop trait indicators.

3. Functional characteristics

1. The Android system has the advantages of simple operation, humanized application, intelligence and upgradeability.

2. Imaging characteristics: Equipped with a 16-megapixel resolution color high-speed camera with autofocus and an ultra-thin backlight light source board, it has the characteristics of automatic correction of camera image distortion and backlight uniformity, effectively reducing the size measurement error. The diameter of the grains for photo analysis is 0.5-20mm. The solid grains and barren grains of rice seeds need to be selected by wind, and then counted and analyzed separately to obtain the rice fruiting rate.

3. Grain counting accuracy and target size: 1-2000 grains/time, grain counting error ≤±0.2%, and minimal monitoring and correction can ensure the accuracy of the results. The accuracy error of thousand-grain weight analysis: ≤±1mg;

4. It can automatically measure the shape parameters (length, width, aspect ratio, area, perimeter) of each type of adhered grain. The measurement error of each size of each type of grain is ≤±0.1mm.

5. There is a record of the sample being tested, and the thousand-grain weight is automatically calculated by inputting the sample weight. The analysis process is automatically controlled by a flat panel, which is efficient, accurate, simple and easy to use, and the counting analysis and thousand-grain weight measurement can be operated with one button.

6. Analysis data export: The analysis image results can be saved, and a total report can be automatically generated. The statistical analysis results can be exported to Excel.

7. The seed testing system is supported by the cloud platform. Data can be uploaded to the cloud platform. Historical data can be retrieved according to any time period and seed category. Data such as measurement time, seed quantity, thousand-grain weight, average area, average circumference, average length, average width and seed picture thumbnails can be viewed. Different parameters can be analyzed by bar charts. Data can be exported in the form of EXCEL tables and printed online. Data can be displayed according to the selected time period, and data can be analyzed in the form of tables, bar charts, etc. It supports online download and printing.

8. Backlight device: It uses a high-brightness LED lamp driven by a power supply, under the action of a nano light guide plate and reflective materials, so that the backlight is clear and the seeds have no shadows on it. The aluminum alloy outer frame is beautiful and strong and not easy to deform.

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