optimises mapping with pre-drawn path

By on 16 February, 2016 have launched SLAM Engine 4.0, which optimises the process of indoor mapping by mobile phone or tablet. With the latest release, introduces an intelligent feature called the ‘pre-drawn path’, to further enhance the user experience.

When doing SLAM recordings in the Mobile Toolkit, which is utilised for mapping a building to enable indoor localisation and navigation, users can now apply this new feature to draw the path they need to walk for the recording later. By sketching your paths, it is possible to plan your routes and make sure that every area is mapped. In the ensuing recording process, users just need to walk along the route at a steady pace and make a recording/ground truth at every planned turn.

The new feature means users no longer have second guess their navigation when doing the recording, they can just calmly walk the pre drawn path and make the ground truth, or control point, where it says. Now when ground truth observations are made, the phone vibrates so you know the ground truth has been established. And in case there have been any mistakes during recording, each single step can now easily be corrected and the recording process doesn’t have to be completely restarted.


Besides several bug fixes and stability improvements, the 4.0 release also includes a new Kalman filter, which helps improve the accuracy by 15% on already existing maps. is focused on developing, optimising and distributing indoor localisation for mobile devices for various use-cases like airport navigation, shopping mall navigation, location-based marketing, meeting room finder and navigation for visually impaired. They are based in Brunn am Gebirge, Austria, has a developer’s hub in Vienna, Austria and an international branch in the Palo Alto, CA, USA.
