This paper provides an overview of 3D scanning methodologies and technologies proposed
in the existing scientific and industrial literature. Throughout the paper, various types of the …

In panoramic three-dimensional (3D) shape measurement based on a turntable, the point
cloud registration accuracy is greatly affected by the calibration of the rotating axis. To …

In industrial measurement and laboratory research, many measured objects are placed on
the three-axis turntable. In this paper, we propose a fast and practical method to determine …

Thin-walled turbine blades with complex features are a critical part of an aviation engine,
and a small change in their geometric shape can erode the performance of the aviation …

Registration of 3D point clouds is an important issue in 3D scanning domain. In this work, we
developed a turntable-base structured light system for the automatically 3ED scanning …

The iterative closest point (ICP) algorithm is one of the most widely used methods for point
sets' registration. However, ICP is very sensitive to the selection of initial points and is easy …

This paper proposes a novel method for calibrating the relative orientation of a camera fixed
on a rotation axis using the constrained global optimization algorithm. Because the camera …

Calibration is a critical step for the projector-camera-based structured light system (SLS).
Conventional SLS calibration means usually use the calibrated camera to calibrate the …

Abstract High-precision three-dimensional (3D) measurement techniques commonly
perform 3D point cloud data stitching using pasted marked points. However, pasted marked …

Industrial measurements increasingly employ a redundant robotic system with an external
turntable due to its efficiency, flexibility, and automation advantages. However, the actual …
