Usages for Photogrammetric Data


Georgia O’Keeffe Imaging Project


• Havana is one of the finest historical centers in Latin America.

• Dire need to record, preserve, and monitor historic structures:

• Old Havana is an UNESCO World Heritage site.

• There are 3,000 historic structures in Old Havana alone.

Office of the Historian: Havana, Cuba


- Tremendous reception- Demo of Photogrammetry- Needs Assessment

Knowledge Transfer

- Cuba’s unique situation- Historical significance- Restoration priority- Lack of resources


- There is a tremendous need- Computing limitations- Inherent issues with large-scale structures

What we learned


Hands on examples for kids


Gustave Baumann’s MarionettesNew Mexico Museum of Art


Transforming Gustave Baumann’s Marionettes into a 3D interactive


The KinectA 3D Natural Interface (NI)device.

Made of:l 1 RGB camera (like a webcam)l 2 infrared sensors that use stereoscopic imaging to interpret depth.

l 4 microphone array that can interpret depth and location by sound.

The Kinect is designed for interface development that does not use physical buttons or other mechanical apparatus to interface with a machine.


Depth InformationIt starts with depth.l Kinect projects out a 3x3 infrared grid and calculates depth based on numbers returned.

What happens next depends on software...


Kinect – Skeletal TrackingSkeletal tracking allows the

Kinect to map a person's movements to a skeletal rig in a 3D model. There are different skeletal tracking options.

For this project, we were able to find an open-source solution that used OpenNI, and PrimeSense's NiTE skeletal viewer (with an educational license provided.)

This allowed us to rig up the model's with skeletons.


Model Preparation


Final Gus Model


Rigging Setup


Unity Setupl OpenNI and PrimeSense NiTE installed through premade package

l OpenNI XML and UnityInterface.DLL included at root level

l AvatarController, KinectManager, and KinectWrapper scripts included in Scripts folder in project

l AvatarController added to each Model

l KinectManager added to Camera
