Geometric Inlier Selection for Robust Rigid Registration With Application to Blade Surfaces

Robotic 3-D measurement for evaluating the final shape of blades can improve product quality and reduce fabrication costs. However, large or complex objects require multiple scans from different viewpoints to capture the entire object. They must then be registered to a common frame. Errors in registration artificially introduce defects and surface discontinuities in the reconstructed object model....
