Charles Woodward (VTT) AR and Social Media for Industry Applications

220 views

Published on

I will present our latest applications on applying AR with Social Media, "Making things Twitter", and explain how to take this further to industrial applications, for example capturing tacit knowledge among maintenance workers. Technical topics include 3D tracking in wide area indoor applications, enabling facility asset management and interaction with BIM and further links to enterprise systems.

Augmented World Expo (AWE) is back for its seventh year in our largest conference and expo featuring technologies giving us superpowers: augmented reality (AR), virtual reality (VR) and wearable tech. Join over 4,000 attendees from all over the world including a mix of CEOs, CTOs, designers, developers, creative agencies, futurists, analysts, investors, and top press in a fantastic opportunity to learn, inspire, partner, and experience first hand the most exciting industry of our times.

Charles Woodward (VTT) AR and Social Media for Industry Applications

  1. 1. Augmented Reality at VTT AR and 3D Tracking research at VTT  VTT is the 3rd largest research institute in Europe with 2,300 employees  AR / 3D Tracking team established in 2001, today 15 people in Espoo  Leading edge tracking technology: ALVAR SDK Application focus  Industrial Maintenance, Assembly, Training  Architecture, Engineering & Construction (AEC)  Facility Asset Management, other wide area applications
  2. 2. Markerless 3D Tracking Point cloud based tracking  Point clouds created from photos  Enabling fast, accurate, robust tracking  Automatic initialization without user interaction  Sensor fusion, extended tracking Tracking targets  Unity based AR authoring: tracking targets and content  Several optimizations, number of points, outliers, lighting etc.  Updating of point clouds: based on user taken photos, robots, drones  Wide areas: dynamic loading of point clouds, edge cloud servers
  3. 3. Wide Area Applications Facility asset management  Building life cycle services: maintenance, operation & repair  Mobile AR interaction with facility’s digital information systems Example: Building maintenance  Building Information Model (BIM) as framework to digital systems  E.g. Facility Maintenance System, Building Automation, IoT Example: Lean construction / renovation  Mobile AR view and interaction with BIM based production plans  Checking for daily work tasks, resources, schedules, etc.
  4. 4. Augmented Social Media Linking real world objects to Social Media  Attach social media posts to real-world objects and view them in mobile AR  Objects are associated with unique hashtags to be used in existing social media platforms  Create new target objects by taking one or more reference image(s)  Objects are recognized visually, no position information required Industrial applications  Collecting maintenance history and commentary  Tweets may be moderated, analyzed and further processed  Tacit knowledge, by maintenance people around the world
  5. 5. ALVAR Tracking SDK ”A Library for Virtual and Augmented Reality”  Computer vision based 3D tracking for AR  World leading performance, accuracy, robustness, speed Modules  ALVAR 2D: marker, multimarker and template based tracking  ALVAR 3D: point cloud based tracking, extended tracking, sensor fusion  ALVAR Studio: Unity based content authoring, point cloud optimization Platforms  iOS, Android, Windows Phone, Windows, Mac, Flash, Silverlight
