  4. Art and Engineering Purely creative

  5. Art and Engineering Entertainment

  6. Art and Engineering Practical and profitable

  7. Art and Engineering Educational

  8. CFL Lab Artist Visions Film Festival • Visual Treasure Hunt • Visitors given clues about the town of Lambertville NJ • They explore the town to find QR codes • Scan QR codes and attach their own message • Visitors’ input becomes collaborative story

  9. Art and Engineering These projects bring engineers close to artists and act as a bridge between the disciplines Each having a goal to relieve the apprehension laymen have to technology Develop tools for creative people, rather than develop creative works

  10. Motivation Create a medium for rich creative works Inspire ideas from artists and engineers alike Enhance education and increase outreach Establish framework for fundamental research

  11. Project Goal Enhance visual experience of a live performance with AR • Visually enhance storytelling • Engage and involve audience • Convey complex ideas • Reduce production costs • Unbind creative limitations

  12. What Is AR ? Display Techniques Head Mounted Displays Handheld Display Spatial Displays

  13. Dance and Engineering in Augmented Reality Camera/Projector Installation Augmented Stage • Marker less stationary objects • IR led marked moving objects • Volumetric objects • Dynamic lighting • Floor projection • High frame rate digital capture • High lumen projector with wide focal range • PC with accelerated graphics

  14. 2D/3D Projector-Camera Calibration

  15. 2D/3D Projector-Camera Calibration Homography(perspective transformation) Stereo Calibration

  16. Kinect “Hacks”

  17. RGBD Sensor Based Calibration • Calibrate RGBD sensor Depth and Image camera separated physically so images do not match Uncalibrated overlay Two different approaches to create image overlay - Homography - Stereo Calibration

  18. Projector – Sensor Extrinsics Real Scene Projection Sensor Capture

  19. Determining Projection Matrix • Determining the projection matrix

  20. Determining Projection Matrix

  21. Displaying the scene

  22. Displaying the Scene
