Sampling Density Criterion for Circular Structured Light 3D Imaging

Lee, D., & Krim, H. (2017, January 1). PROCEEDINGS OF THE 12TH INTERNATIONAL JOINT CONFERENCE ON COMPUTER VISION, IMAGING AND COMPUTER GRAPHICS THEORY AND APPLICATIONS (VISIGRAPP 2017), VOL 6, pp. 478–483.

By: D. Lee* & H. Krim n 

author keywords: 3D Reconstruction; Structured Light Pattern; Sampling Theorem; Geometry
topics (OpenAlex): Advanced Optical Sensing Technologies; Surface Roughness and Optical Measurements; Industrial Vision Systems and Defect Detection
TL;DR: An approach to sampling rate (lower / upper b ound) determination to recover 3D objects represented by a set of circular light patterns, where the criterion for a sampling rate is formulated using geometric characteristics of the light patterns over laid on the surface.

A Sampling Theorem for a 2D Surface

Lee, D., & Krim, H. (2012, January 1). Lecture Notes in Computer Science, Vol. 6667, pp. 556–567.

By: D. Lee n & H. Krim n 

topics (OpenAlex): Optical measurement and interference techniques; Digital Image Processing Techniques; Medical Image Segmentation Techniques
TL;DR: A new approach to determining an optimal sampling rate for a 2D-surface reconstruction using the so-called Two-Thirds Power Law is proposed, which is of interest in a number of applications such as 3D face recognition and development of new efficient 3D cameras. (via Semantic Scholar)

3D Surface Reconstruction Using Structured Circular Light Patterns

Lee, D., & Krim, H. (2010, January 1). Lecture Notes in Computer Science, Vol. 6474, pp. 279–289.

By: D. Lee n & H. Krim n 

topics (OpenAlex): 3D Surveying and Cultural Heritage; Optical measurement and interference techniques; Remote Sensing and LiDAR Applications
TL;DR: A novel approach to reconstructing 3D coordinates of a surface from a 2D image taken by a camera using projected circular light patterns based on a geometrical relationship between a given pattern projected onto a 3D surface and a pattern captured in a2D image plane from a viewpoint is proposed.
