Photogrammetry for videomapping and VR

One Sentence: Whats happening in your workshop?
Photogrammetry is a method of reconstructing 3D geometry and texture of an arbitrary object using photo camera.

We will introduce basics of photogrammery in the context of VVVV. We will use software tool Reality Capture mainly because its unprecedented reconstruction and alignment speed . Focus will be given on scenarios such as videomapping, virtual reality and Kinect depth camera alignment.

In the introduction part, we will explain the process of photogrammetry, briefly mention tools alternative to Reality Capture ranging from 123D Catch to Photoscan.

In second part we will go through the process of object reconstruction from the photo shooting to import into VVVV.

While in VVVV we can easily preview the reconstructed model view VR headset.

Finally we will align projection of our 3D scan back to the original object or its 3D printed scale model.

If there will be time left, we can cover alternative techniques of Kinect sensor alignment using photogrammetry.

We will not cover non-realtime rendering or model cleanup techniques.

What 3 tags describe your workshop?
Photogrammetry, videomapping, VR

In which of the three categories does your workshop fall: beginner, intermediate, advanced
Intermediate, but we believe our workshop will be informative and inspiring even for an advanced users.

How long will your workshop be?
2x 3h

Who is the target audience of your workshop?
VVVV users creating video mapping projects and virtual reality experiences.

What knowledge do you presume your participants have?
VVVV, DX11, basics of 3D modeling. Eventual workshop on Transformations and Camera Calibration techniques is a good prerequisite. We recommend you take Pointclouds afterwards.

What will attendees of your workshop learn?
How to apply photogrammetry using in the context of videomapping to reconstruct geometry of object to project onto, preview the content, speedup the warping process, plan the location setup, projector placement and other site specific requirements.

What technical requirements does your workshop have (apart from internet and a projector)?
We are able to bring desktop machine (i7-6700+GTX1070) and HTC Vive headset.

Developer of Reality Capture is willing to support us with licenses for workshop participants.

We will bring 3D printed architectural model to project on.

Additional projector(s) would be helpful.

It would help to have access to an additional headset.

For participants it is recommended to bring DSLR camera, although recent smartphones will do.

Who would be the two hosts?
Andrej Boleslavsk√Ĺ aka id144
Chris Plant aka catweasel

How would the hosts qualify for the topic? (Describe and add links to portfolio website, github, vimeo,… accounts)
