Description du poste

**Domaine**:

- Sciences pour l'ingénieur

**Contrat**:

- Stage

**Intitulé de l'offre**:

- Accurate 3D scene reconstruction from images with neural Method H/F

**Sujet de stage**:

- Stage

However, those techniques have limitations in terms of robustness and accuracy when it comes to large environments and specular objects such as metallic surfaces in an industrial environment.

**Durée du contrat (en mois)**:

- 6

**Description de l'offre**:
**Missions**:

- During this internship, you will explore the state of the art techniques for 3D scene reconstruction from 2D image using Neural Fields. With a focus on the accuracy of reconstructed geometry, you will design and develop a method of 3D surface reconstruction, which will be applied to industrial environment.

The internship will notably include:

- Reviewing existing literature on the topic
- Selecting and implementing an existing approaches in the Neural Fields framework NeRFStudio
- Benchmarking the new method using images capturing an industrial environment

**Job-related benefits**
- Joining the CEA List and the LVML as an intern means:

- Working in one of the most innovative research organizations in the world, addressing societal challenges to build the world of tomorrow
- Discovering a rich ecosystem: privileged connections between the industrial and academic sectors
- Conducting research autonomously and creatively: encouragement to publish results (scientific articles, patents, open-source codes...)
- Join a young and dynamic team
- Benefit from an internal computing infrastructure with more than 300 state-of-the-art GPUs
- Receive a stipend between €1300 and €1400 per month
- Have the opportunity to continue with a PhD or as a research engineer after the internship
- Receive a 75% reimbursement on public transportation costs, and benefit from the “mobili-jeune” aid to reduce rent costs
