Episode notes
3D Maps Are The Gateway To Accurate AR
- 3D maps are the critical infrastructure to anchor AR content with centimeter precision rather than relying on GPS.
- Visual positioning systems (VPS) use camera streams to achieve accurate localization for AR and smart glasses.
Founders Met Through Mining And AR Work
- Diego met his co-founder Davide during a university startup presentation and initially sold him GPUs for mining.
- They combined Davide's decade of AR experience with crypto interest to start Over.
Hardware + Algorithms Made Scale Possible
- Advances in GPUs and reconstruction algorithms reduced map processing time from 24 hours to about 35 minutes.
- These hardware and algorithmic gains made large-scale 3D mapping practically and economically viable.
