Non-destructive weld integrity detection using RGB and thermal computer vision
This innovative solution utilizes RGB and thermal imaging combined with deep learning to non-destructively detect weld defects in TPO membranes. It offers real-time, accurate detection for 45, 60, and 80 mil thicknesses, reducing reliance on manual inspection methods.
Overview
This cutting-edge technology employs RGB and thermal imaging paired with deep learning to non-destructively detect defects in thermoplastic polyolefin (TPO) membrane welds. By capturing heat anomalies through thermal imagery and surface defects via RGB, the system ensures accurate, real-time detection. This approach is applicable to TPO membranes of 45, 60, and 80 mil thicknesses, offering a reliable alternative to manual inspection or destructive testing methods.
