A Tutorial on Single-Shot 3D Surface Imaging Techniques [Lecture Notes]

Abstract

In recent years, noncontact 3D surface imaging techniques have made great progress due to advances in optical devices and image processing. The single-shot technique is essential for 3D surface imaging techniques to accurately calculate the 3D shape information of the irreversible transient surfaces in the high-speed dynamic scene. In this tutorial, we provide a review of recent advances in existing single-shot 3D surface imaging techniques. The recent advances in single-shot 3D surface imaging techniques lie in the abundant emergence of new methods, the increased measurement resolution, and the increased measurement accuracy. We particularly focus on the single-shot 3D surface imaging techniques that are based on structured light (SL) coding.
