Real-Time 3D Profile Measurement Using Structured Light

Real-Time 3D Profile Measurement Using Structured Light

The paper builds a real-time system of 3D profile measurement using structuredlight imaging. It allows a hand-held object to rotate free in the space-time coded light field, which is projected by the projector. The surface of measured objects with projected coded light is imaged; the system shows surface reconstruction results of objects online. This feedback helps user to adjust object’s pose ...

Accurate 3D measurement using a structured light system

This paper discusses a method for obtaining accurate 3D measurements using a temporally encoded structured light system. An objective of the work was to have a balance in the accuracy of all components in the system. This was achieved by including lens distortion in the models for both the camera and projector which comprise the structured light system. In addition, substripe estimation was use...

White Light Spectral Interferometry for Real-time Surface Profile Measurement

This paper presents a high speed surface profile optical measurement technique based on white light spectral interferometry and parallel signal processing using a general purpose graphic processing unit (GPGPU). A white light source is used to acquire the surface profile of the sample instantly in real time through a cylindrical Michelson interferometer. The interference signals are resolved by...

Virtual Noctiluca: Interaction between Light and Water Using Real-Time Fluid Simulation and 3D Motion Measurement

In recent years, with the rapid improvement of the performance of computers, new possibilities for real-time simulation technologies are emerging. In this study, we simulated the behavior of water in real time and combined this simulation with a measurement of the user’s 3D motion to simulate the interaction between water and light, as observed in Noctiluca. Noctiluca is oceanic plankton that p...
