Open AccessLearning-based active 3D measurement technique using light field created by video projectors
The combination of a pattern projector and a camera is widely used for 3D measurement. To recover shape from a captured image, various kinds of depth cues are extracted from projected patterns in the image, su...

Robust Structured Light System Against Subsurface Scattering Effects Achieved by CNN-Based Pattern Detection and Decoding Algorithm
To reconstruct 3D shapes of real objects, a structured-light technique has been commonly used especially for practical purposes, such as inspection, industrial modeling, medical diagnosis, etc., because of sim...

Wide-Area Shape Reconstruction by 3D Endoscopic System Based on CNN Decoding, Shape Registration and Fusion
For effective in situ endoscopic diagnosis and treatment, dense and large areal shape reconstruction is important. For this purpose, we develop 3D endoscopic systems based on active stereo, which projects a grid ...

Auto-calibration Method for Active 3D Endoscope System Using Silhouette of Pattern Projector
In this paper, we develop an active stereo system for endoscope which requires auto-calibration, because a micro pattern projector is inserted through the instrument channel during an operation and cannot be f...

Two Plane Volumetric Display for Simultaneous Independent Images at Multiple Depths
We propose a new projection system to visualise different independent images simultaneously on planes placed at different depths within a volume using multiple projectors. This is currently not possible with t...

Shape Acquisition and Registration for 3D Endoscope Based on Grid Pattern Projection
For effective endoscopic diagnosis and treatment, size measurement and shape characterization of lesions, such as tumors, is important. For this purpose, 3D endoscopic systems based on active stereo to measure...

Single Color One-Shot Scan Using Topology Information
In this paper, we propose a new technique to achieve one-shot scan using single color and static pattern projector; such a method is ideal for acquisition of a moving object. Since a projector-camera systems g...
