Summary

The InterDigital Immersive Video Lab is dedicated to advancing avatar-based communication. In this context, this internship aims to transform an existing photography setup comprising 14 DSLR cameras into a multi-view video capture rig. The primary objective is to develop a complete acquisition pipeline for synchronized recordings of facial expressions and head movements. The work will begin by assessing the cameras’ video capabilities, synchronization options, and data transfer constraints. It will include camera calibration, lighting configuration, and the development of tools to control and monitor recording sessions. Particular attention will be given to temporal alignment, consistent exposure, and image quality across viewpoints. A facial capture protocol will define the expressions, speech sequences, and head movements required for avatar reconstruction and animation. The second objective is to produce a structured multi-view video dataset for real-time avatar calls using 3D Gaussian Splatting. The dataset will include recordings from multiple participants, calibration data, capture metadata, and predefined training and evaluation sequences. The expected outcomes are an operational video capture rig, a documented acquisition workflow, and a quality-checked dataset collected with participant consent.
