Visual Positioning Systems: what they are, best use cases, and how they technically work
- Visual Positioning Systems (VPS) are a cloud service enabling applications to localize a user’s device at real-world locations to interact with persistent AR content
- VPS detects the exact position and rotation of a device to correctly interact with AR content in physical places
- VPS is superior to GPS for AR placement and is useful in indoor navigation, industrial work, marketing, entertainment, and metaverse development
- VPS uses feature detection for localization and mapping that are essential VPS operations, with reliable corner features for reconstruction of the whole place using overlapping features from different images
- VPS SDKs provide flexibility to the developers to import maps and place virtual objects, while immersal SDKs offer preview features of these maps before localization
- VPS Systems have different compatibility options, device compatibility, available for on-cloud and on-device localization, work better in either indoor or outdoor environments, have different map scale targets, are either closed or open systems, and have varying price ranges
- Immersal is one of the companies that create VPS services and maps using mobile devices, 360 cameras, Matterport scanners, LiDAR scanners, and drones.
- Immersal can be used on various AR capable devices, both mobile and AR glasses, offers customizable map feature editing, combines SDKs with AR Foundation to make a lightweight AR application that still relays accurate VPS tracking.
- Comparing Immersal and other VPS systems, Google Geospatial’s free VPS service offers high accuracy for outdoors while Immersal’s paid service offers better performances for outdoor locations and indoor applications.
- Niantic Lightship is suitable for gaming and expanding 3D maps while industrial clients may appreciate Immersal’s data safety features for customized 3D maps.
