Kinect OpenCL 3D Scan

Posted in experimental with tags , , on July 11, 2012 by Francois Wunschel

I gave a shot at scanning my friend using a Kinect-based openCL scanner,
which was also a good opportunity to test our new PC laptop (wtf?!) sporting a roaring Nvidia GeForce GTX 670M 3 Go GDDR5.
This gfx card simply buries my macbook’s AMD Radeon HD 6750M …

AAPL: it’s about time to bundle some serious gear in your laptops.

Here’s the resulting meshed point cloud, at 250K+ vertices :

MAD_KinectMasker tutorial

Posted in MadMapper with tags , , on August 8, 2011 by Francois Wunschel

EDIT: this tutorial is now depreciated, as MadMapper supports QuartzComposer files natively.
We offer the original QC patch for free to anyone, get it from
MadMapper forum

In this tutorial, will use the newly released MAD_Lab applications
to plug a Kinect to your Mac and do so realtime masking… !

So first, launch MAD_KinectMasker application.
This app. uses the v002 OpenKinect plugin (bundled into the app) kindly provided by v002 team and the Syphon plugin.

MadMapping Workshop #1

Posted in experimental, MadMapper with tags , , on May 25, 2011 by Francois Wunschel

Day 01.
All participants arrived.
Mini-face-mapping unit deployed.
Faces scanned and mapped.
Using a Kinect to extract faces from background, pictures sent back to Modul8, mapped with MadMapper.

Make The Line Dance / Video

Posted in experimental, MadMapper, video mapping with tags , , , on March 21, 2011 by Francois Wunschel

Video report of an Augmented Dance session test.
I finally managed to reduce the latency a bit, perceptually at least.
Using a Kinect for skeleton tracking,
QC to render the lines (+1024_ParticleWarfare + 1024_Rope + 1024_Skeleton),
MadMapper (+Syphon) to match video and real action,
MaxForLive for the randomly generated piano sounds.
And a Canon 5D SLR for the shooting.



Hardware latency

Posted in experimental with tags , , on March 10, 2011 by Francois Wunschel

As kindly pointed by master Memo, I tested my hardware latency.

First photo is the projector latency: displaying the same timecode on both computer screen and the projector, in this case an Optoma EP759.
On top the proector timecode, bottom the computer timecode:

Result is a 16ms latency. 1 frame at 60FPS.

Now testing the Kinect unit. Same procedure. Note that I’m using v002_OpenKinect QC plugin by Vade to display the Kinect Color Image.
On top the computer timecode, on the bottom the Kinect grabbed timecode:

Result is an amazing 80ms latency !

Each test was repeated 3 times in order to have consistent results.
So with this setup I have an overall 6 frame delay (roughly).
I guess you can’t expect more from a 150euros plastic consumer product.
And it also confirms my gaming impressions on the Xbox.

Since the Kinect is grabbing frames -apparently- at 30FPS, I’ll lock my output to 30FPS as well, and hopefully reduce the latency to 3 frames…
I’d be happy if anyone can confirm these tests.

Make the line dance

Posted in experimental with tags , , , on March 9, 2011 by Francois Wunschel

Yet another experimentation with a Kinect unit, Skeleton recognition and video mapping.
The system is working so far, but there’s an annoying one frame delay that forces to move slowly. Video in the making.
