Augmented Reality/Photogrammetry Workshop

Description

This four–hour workshop provides novice users with hands-on, expert introduction to two emerging technologies augmented reality and photogrammetrytechnologies:

Augmented reality can be used to place virtual 3D objects so that appear anchored to a tracking image.

Photogrammetry is a technique that converts sets of photographs into 3D models.

By the end of the workshop, participants will be able to:

  • Create a photogrammetry self portrait avatar
  • Make the avatar viewable as augmented reality
  • Understand how to use mobile augmented reality browsers
  • Test, view and document their work

Participation Requirements:
Participants are encouraged bring a late model mobile device (iPhone, iPad or Android smartphone); however, extra devices will be provided for those who cannot provide such a mobile device. Students will be provided with the necessary access to state-of-the-art computer equipment and Internet connection.


Download the free DAQRI Augmented Reality App to view this image with any late model iPhone, iPad or Android mobile device.
