Automatic grain assesment

The system operates using a two-stage mechanism designed for isolating, transporting, and imaging individual grains.

First, the grains are placed into a small funnel that uses a combination of circular motion and vibration. This controlled movement helps guide the grains into a single-file flow, ensuring that only one grain at a time passes through the aligned holes.

After passing through the funnel, each grain is transferred onto a rotating disk-like structure (V-shaped groove) that is divided into four functional sections:

• 1. Collection Section
  Receives the grain from the funnel and positions it for further processing.
• 2. Sensing Section
  Uses optical or infrared sensors to confirm the presence of a single grain and verify proper alignment before imaging.
• 3. Imaging Section
  Moves the grain into a dedicated imaging zone where cameras and controlled lighting capture high-quality images.
• 4. Drop/Disposal Section
  After imaging, the grain is released through an opening so the disk can rotate and prepare for the next cycle.

This four-section disk design ensures an efficient, step-by-step workflow for each grain, improving reliability, throughput, and automation of the imaging process.
