Offer Description

This position is part of the CNRS "OPEN" valorization project named DOPAMIn. It aims to transfer state‑of‑the‑art 3D reconstruction technology (RNb-NeuS), derived from academic research, into the open‑source industrial software AliceVision/Meshroom, in collaboration with the University of Zurich.

Mission

The researcher will integrate, optimise, and stabilise the RNb‑NeuS neural 3D reconstruction method within the AliceVision software architecture, enabling the creation of high‑precision digital twins.

Activity 1: Integration of Photometric Stereo in Meshroom

• Implement processing nodes for normal field and intrinsic colour estimation.
• Integrate deep learning‑based methods (such as SDM‑UniPS or Uni‑MS‑PS).

Activity 2: Implementation of the RNb‑NeuS Module

• Develop the neural reconstruction node using photometric data as input.
• Ensure interfacing with the AliceVision library.

Activity 3: Critical Code Optimization (C++/CUDA)

• Adapt the code to drastically reduce computation times (target: < 1 h).
• Replace proprietary dependencies (InstantNGP) with a flexible base (such as SuperNormal).

Activity 4: Reliability and Robustness

• Develop mechanisms for outlier rejection.
• Document the code for the open‑source community.

Full‑time work. Position based at the IRIT‑ENSEEIHT campus in Toulouse. Integrated within the REVA team at IRIT. Strong interaction with ALICIA‑Vision LabCom partners (CNRS / Technicolor‑Mikros).

Knowledge

• In‑depth expertise in Computer Vision and Photogrammetry.
• Mastery of state‑of‑the‑art Neural Rendering (NeRF, NeuS, SDF).
• Knowledge of Photometric Stereo methods.

Operational Skills

• Advanced programming in C++ and Python.
• Mandatory mastery of GPU programming (CUDA) for optimisation.
• Experience with Deep Learning frameworks (PyTorch).
• Knowledge of the AliceVision architecture is a major asset.

Soft Skills

• Autonomy and scientific rigour.
• Ability to work collaboratively (mixed academic/industrial context).
• Ability to meet short development deadlines (project mode).
