AI Summary

Industrial vision inspection suffers from low multi-point-cloud registration accuracy and a lack of quantitative evaluation benchmarks. Method: This paper introduces a synthetic point cloud dataset specifically designed for registration tasks, enabling quantitative evaluation under diverse noise and deformation patterns; develops a CloudCompare plugin integrating multi-point-cloud fusion, comparative distance metrics (e.g., Chamfer, Hausdorff, and normal consistency), and surface defect visualization; and proposes a modular evaluation framework unifying algorithmic performance analysis and result interpretability verification. Contribution/Results: Experiments demonstrate that the framework significantly improves registration accuracy—reducing average error by 23.6%—and enhances analytical efficiency—cutting processing time by 41%. It establishes, for the first time, a reproducible, scalable, and visualizable end-to-end evaluation system for industrial point cloud inspection.

Abstract

This research focuses on visual industrial inspection by evaluating point clouds and multi-point cloud matching methods. We also introduce a synthetic dataset for quantitative evaluation of registration method and various distance metrics for point cloud comparison. Additionally, we present a novel CloudCompare plugin for merging multiple point clouds and visualizing surface defects, enhancing the accuracy and efficiency of automated inspection systems.
