Multimodal fusion system for NDT and Metrology

Abstract

3D scanning and modeling is used in a wide range of applications like manufacturing, aerospace, security, biomedicine, etc. This kind of systems allows the scanning of a 3D point cloud that can be meshed and rendered in order to obtain a complete 3D model. However, 3D vision cannot detect subsurface defects. This later can be achieved using other imaging modalities, like thermal infrared imaging. This modality is very popular in non-destructive testing and visual inspection. In this work, we present a multi-modal fusion framework for combining these two modalities. We present an approach for a robotic inspection system integrating the proposed framework for 3D-NDT multimodal control and analysis.
