Lightweight, system agnostic
Running on a standard Linux hardware and utilising a standard low cost unstabilised RGB camera input. Odigia's ALaN system is both low cost and small.
- Low cost, mobile consumer processing power.
- Linux-based, enabling rapid system integration.
- Built with unstabilised RGB cameras - minimising system cost and guaranteeing system integration.
Cold-start localisation
ALaN does not require an accurate known location to begin localisation. This makes it significantly more capable than an IMU.
- Localise from unknown locations
- Relocate after sensor occlusion.
- IMU location verification
