Accuware Dragonfly Preview

Accurate 3D positioning using SLAM

INTRODUCTION

The Dragonfly application is meant to be a preview app to test Accuware Dragonfly SLAM capability. This is our latest product: a computer vision-based indoor positioning system (IPS) capable of delivering a mobile device’s location with centimeter accuracy, without any dedicated hardware or infrastructure.

===========

GET STARTED

The orientation is fixed to landscape only.

After first start the app will ask you for your permissions to use the camera. You need to grant that, otherwise it will not work.

To start the positioning press the Dragonfly at the center of the screen.

The app enters the positioning mode using a default camera calibration set or - if available - a device specific calibration set.

However, it is recommended to perform a local camera calibration in order to obtain the optimal positioning results. Please refer to the calibration tutorial and the inbuilt documentation for details. We encourage you to do a calibration.

Since there is no geo-referencing of the internal 3D model, all positions are just plotted as raw, unit-less X, Y and Z coordinates.

TECHNOLOGY

Accuware Dragonfly is a visual SLAM-based system. Dragonfly uses a camera video stream to perform Simultaneous Localization And Mapping (SLAM), a technique described as “the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of a device's location within it “. The device in question is a device equipped with a camera, in this case your Android device.

Dragonfly uses the device’s camera to analyze its surroundings, map the environment around it, and determine its location in reference to its physical context.

The app provides a built-in 3D viewer to see your location in real time.

No site setup is required.
