TL;DR: Simulations and experiments show that the proposed closed-form iteration combined weighting method can improve the registration accuracy, and the proposed GPR-based volumetric error prediction and compensation method can achieve high accuracy with a simple measurement process.

TL;DR: In this article, the projected centerline of each pipe is split into several NURBS curves, and these curves are taken as the primitives of matching to be reconstructed and registered precisely.

TL;DR: The proposed pattern encoding strategy makes the range of unique phase distribution up to 10 pi, which is 5 times as large as 2 pi of conventional four-step phase shifting encoding approach, which enables the structured light-based measurement system to measure complicated objects without ambiguity.

TL;DR: The proposed automatic multiple-needle surgical planning of optimal insertion trajectories to the targets, based on a mathematical description of all relevant structure surfaces, can improve the efficiency and safety of robot-assisted large liver tumor therapy, significantly reduce the surgeon's workload, and is especially helpful for an inexperienced surgeon.

TL;DR: A stereo vision based method that can measure the bend radius automatically without artificial operations and show good performance in terms of precision and reliability, even when lacking corresponding points or with incomplete edges.
