Enhancing Automated Meat Grading with Depth Estimation

Based on Patent Research | US-2020074613-A1 (2020)

Automating meat grading presents difficulties due to inconsistent cut surface positions. This variability hinders acquiring high-quality images needed for accurate grading. Such issues cause inefficiencies and potential inaccuracies. Depth estimation, a computer vision task, precisely determines the cut surface's 3D position. This allows optimal 2D image capture. It enhances grading accuracy and overall process efficiency.

SOLUTION OVERVIEW

Manual Grading to Automated Depth Analysis

Depth estimation technology offers a precise solution for challenges in food manufacturing, particularly for automated meat grading. This computer vision task directly addresses the difficulty of inconsistent meat cut positioning. It operates by capturing detailed 3D spatial information of the meat, creating a comprehensive depth map. This map allows systems to accurately pinpoint the exact location and orientation of the cut surface. Consequently, it enables optimal adjustment of camera perspectives for capturing high-quality 2D images, crucial for reliable grading.

This capability significantly enhances the efficiency and accuracy of quality control processes. By automating the optimal image acquisition, depth estimation reduces reliance on manual adjustments and minimizes potential human error in meat processing. It seamlessly integrates with existing production lines, allowing for continuous, high-throughput operations. Consider it like a sophisticated robotic arm in a packaging plant, precisely adjusting its grip based on the exact dimensions of each item to ensure perfect placement every time. This leads to more consistent product quality and streamlined operational workflows across the entire food manufacturing operation.

HOW IT WORKS

Reading Depth in Meat Scans

Capturing 3D Meat Data

Specialized sensors rapidly acquire detailed three-dimensional data of each meat cut on the production line. This process captures the precise spatial arrangement and contours of the product. The result is a rich dataset forming the basis for subsequent analysis.

Generating Depth Maps

The captured 3D data is then fed into advanced computer vision algorithms. These algorithms process the information to construct a comprehensive depth map, which visually represents the exact distance of every point on the meat's surface. This map provides a precise spatial understanding of the product.

Pinpointing Cut Surface Position

The system analyzes the generated depth map to accurately identify and isolate the specific cut surface of the meat. It precisely determines the 3D coordinates and orientation of this critical area. This step ensures that inconsistencies in meat positioning, common in food manufacturing, are effectively overcome.

Optimizing Image Capture

Based on the precise 3D position and orientation of the cut surface, the system automatically directs and adjusts the imaging equipment. This enables the capture of high-quality, perfectly framed 2D images. These optimized images are then ready for accurate automated meat grading.

Potential Benefits

Improved Grading Accuracy

Depth estimation ensures optimal image capture by precisely locating meat cut surfaces. This significantly enhances the reliability of automated meat grading, leading to more consistent product quality.

Boosted Operational Efficiency

By automating precise camera adjustments, the system reduces manual intervention and speeds up the grading process. This allows for continuous, high-throughput operations in food manufacturing.

Minimized Human Error
