This paper presents a new tool for external quality control in welds using close-range photogrammetry. The tool allows for automatic assessment of welds based on 3D photogrammetric models, providing objective and accurate analyses. The tool was validated in both laboratory tests and real scenarios.
This paper presents a new tool for external quality control in welds using close-range photogrammetry. The main contribution of the developed approach is the automatic assessment of welds based on 3D photogrammetric models, enabling objective and accurate analyses through an in-house tool that was developed, WELDMAP. As a result, inspectors can perform external quality control of welds in a simple and efficient way without requiring visual inspections or external tools, and thus avoiding the subjectivity and imprecisions of the classical protocol. The tool was validated with a large dataset in laboratory tests as well as in real scenarios.
