Show & Tell #3

Progress on this has been a little slow lately, but now by defining a few points (0, X,Y and Z axis) in the image that I know match a cube in the real space, I can have the POSIT [0] algorithm generate a virtual camera pose and viewport to match, which I can then fine tune.

After that the 2D position of the tracked object is projected into 3D space, and by combining the two I can get a 3D location.

Since I know the measurements in real space (a 2 metre cube in this case) I can match that to reality. At least this is the idea.

I still need to check if the values make sense as I move across, in the test video I am stopping at 50 cm intervals and lower the orange 1.5 metres.

Accuracy is a big problem of course, so many inaccurate things are building on top of each other, but this will come in handy for other project someday I'm sure.

Thanks to Zach Gage and Memo Akten for the *awesome* class. It was amazingly fun to go from a blank iPhone+oF project all the way through a working Pong implementation!

I've been working a bit on the video tracking part of the project.

The idea is that two cameras are used, one for XY and one for Z.

Here for debugging I'm using the same video on both, a short clip of peach I tied one a piece of string, but I need to set up a small test bed for this soon.

A bit of filtering and you have yourself the blob you are interested in and can transform from the camera positions into virtual space. The exact filtering steps will probably change later, now I get away with just some thresholding and erosion.

On the electronics side I've just taken delivery of one of these motors:

It's pretty powerful, and a lot more directed than the fan I was using.

In association with the first international OpenFrameworks World-Wide Developers Meeting, some of the world’s leading computational artist/developers will discuss their pioneering work at the intersection of arts and computer science.

During the week, the OpenFrameworks core development team is encamped at the STUDIO for Creative Inquiry to advance the next version of OpenFrameworks, a toolkit for new media education and creative coding. Each evening at 5pm, we will feature three or four short presentations by members of this team.

Presenters/Participants Include:

Zachary Lieberman / Theodore Watson / Arturo Castro / Mehmet Akten / Todd Vanderlin / Anton Marini / Damian Stewart / Kyle McDonald / Keith Pasko / Diederick Huijbers / Daito Manabe / Dan Wilcox / Jonathan Brodsky / Zach Gage

OpenFrameworks(OF) is a powerful, open-source toolkit for creative coding in C++.
