Advancing Internal Defect Detection using Image Segmentation

Based on Patent Research | US-2024133848-A1 (2024)

Detecting internal defects in wood members is a persistent challenge for structural reliability. Current imprecise methods often compromise wood quality, risking construction failures. Image segmentation, which identifies and outlines defective areas within converted ultrasonic images, offers a precise solution. This enables automated, reliable defect detection, ensuring superior wood quality and enhancing structural integrity.

SOLUTION OVERVIEW

Manual to Automated Detection Shift

For the Forestry and Logging industry, Image Segmentation technology offers a precise solution to the challenge of detecting internal wood defects. This process begins by converting ultrasonic scan data from timber into detailed 2D or 3D images. AI-powered segmentation algorithms then meticulously analyze these visuals, automatically identifying and outlining specific defective regions. This allows for clear visualization of internal issues, moving beyond imprecise visual inspections to provide reliable defect mapping.

Such automated defect analysis integrates seamlessly into existing timber processing lines, enhancing efficiency and consistency. It reduces the need for manual, subjective assessments, thereby improving overall wood quality control. Consider it like a highly skilled timber grader who can see inside every log, precisely marking out internal flaws that would otherwise remain hidden. This capability provides a foundation for optimizing resource utilization and elevating the structural integrity of wood products, driving significant operational improvements across the industry.

HOW IT WORKS

From Wood Scans to Defects

Capturing Ultrasonic Timber Data

High-frequency ultrasonic waves are directed through wood members, penetrating their internal structure. This process gathers raw wave data, providing crucial insights into the timber's composition and potential hidden anomalies without causing damage.

Converting Data into Visuals

The collected raw ultrasonic data undergoes advanced correction and precise visualization. It is then transformed into detailed 2D or 3D images, represented with RGB to clearly highlight internal structural variations and prepare for analysis.

Segmenting Internal Wood Defects

AI-powered image segmentation algorithms meticulously analyze these generated visual representations of the wood. The system automatically identifies and precisely outlines specific defective regions, such as internal cracks, knots, or decay, enhancing detection accuracy.

Mapping and Visualizing Flaws

The precisely outlined defective areas are compiled into comprehensive, easy-to-understand internal defect maps. This provides clear, actionable visualizations of internal issues, enabling reliable quality control and informed decisions for timber processing lines.

Potential Benefits
