Plenoptic Stages (Light Stages) in Deemos Technologies and ShanghaiTech MARS lab

Introduction

Systems that can generate self-defined gradient illumination patterns and synchronize with camera systems to acquire visual data sequences of objects, which can be used to generate pore-level facial models for relighting use in the film industry, game industry, or light commercial use like video meetings. These systems can work at high-speed rate up to 100hz, which is top-tier performance in the world. Many Commercial Products and Paper have been developed based on the systems we developed.

Contribution

Worked as a 2 people team, developed and produced 2 generations of light stages.

• Design and Engineering of the PCB, code, and structure of the Embedded light systems.
• Design and Engineering of the physical structures and nodes boards of the frame.
• Engineering of the data acquisition system.
