My perspective Part I What is computer vision? What is 3D reconstruction? From pixels to 3D points Structure from motion A quasi-dense approach From 3D points to objects Small-scale objects Smooth surfaces. Hairs. Trees Large-scale buildings Facade, Buildings, Cities Part ll Large-scale automatic 3D mapping ConclusionsMy perspective • Part I – What is computer vision? – What is 3D reconstruction? – From pixels to 3D points • Structure from motion • A quasi-dense approach – From 3D points to objects • Small-scale objects – Smooth surfaces, Hairs, Trees • Large-scale buildings – Façade, Buildings, Cities • Part II – Large-scale automatic 3D mapping • Conclusions
