Model-Free 3D Reconstruction of Weld Joint Using Laser Scanning [PDF]
arXiv, 2014 This article presents a novel utilization of the concept of entropy in information theory to model-free 3D reconstruction of weld joint in presence of noise. We show that our formulation attains its global minimum at the upper edge of this joint. This property significantly simplifies the extraction of this welding joint.

An Adaptive Sampling Approach to 3D Reconstruction of Weld Joint [PDF]
arXiv, 2015 We present an adaptive sampling approach to 3D reconstruction of the welding joint using the point cloud that is generated by a laser sensor. We start with a randomized strategy to approximate the surface of the volume of interest through selection of a number of pivotal candidates.
