What is SolAR?

SolAR is an open-source framework under Apache v2 license dedicated to Augmented Reality.


SolAR is modular and evolutive. It allows, in various contexts of use, the construction of customized computer vision pipelines targeting Augmented Reality applications (e.g. camera pose estimation or 3D mapping).


SolAR contains:

  • interfaces promoting interoperability
  • computer vision components constructed from third-party bricks
  • plugins for third-party applications
