The LabVIEW Kinect code keeps rolling in. I am happy to share yet another example that is available for free download.
This one is very similar to John Wu’s LabVIEW + Kinect example I shared awhile back. Karl Muecke, NI R&D engineer, shares his 6D visualization example on the NI Robotics Code Exchange.
You can view a video screen capture of the demo and download his open source code here:

If you haven’t seen this already, you need to. The Xbox Kinect is not only revolutionizing gaming, it will revolutionize the way humans interact with machines, including robots (think: robots can now more easily interpret human gestures).
Ryan Gordon, from http://ryangordon.net/, got things started by building and sharing a LabVIEW wrapper for the OpenKinect library. Then John Wu, another LabVIEW programmer, took things one step further building an example VI for 3D scene construction using the Kinect sensor and point clouds.
Download John’s example on his blog post: LabVIEW, Xbox Kinect, and 3D point cloud visualization
Thank you John and Ryan! This is the beginning of some incredible and exciting work!
Open Source LabVIEW Code: LIDAR Example featuring Radiohead September 15, 2009

This one is compliments of Alessandro Ricco, a LabVIEW Champion in Italy who had some free time on his hands. He was inspired by Radiohead’s music video for House of Cards. Some of you may recall, this is the music video that was created without any filming, whatsoever. Rather, the producers recorded 3D images of Thom Yorke singing the lyrics with a Velodyne LIDAR sensor and then played back the data, in sync with the song.
I mentioned LIDAR technology before when describing the Blind Driver Car from Virginia Tech. There’s a ton of other robots that I’ve come across that use LIDAR for sensing and perception, so I figured you robot builders out there might be interested in getting your hands on some code to do this yourself.
Start by downloading Alessandro’s example here. You’ll need LabVIEW 8.5 or newer. If you don’t have LabVIEW, you can download free evaluation software here (be warned, it might take some time to download).
You’ll also need to find yourself some LIDAR data. If you don’t have a $20,000 LIDAR sensor lying around the lab, you can simply download the LIDAR data from the Radiohead music video from Google Code.
On the other hand, if you do have a LIDAR lying around and let’s say you want to create your own music video (or perhaps more likely, if you just want to create a video recording of the 3D data your mobile robot just acquired), Alessandro also includes a VI that saves each 3D plot as a .jpeg and then strings them all together to create an .avi. Here’s where you can find the necessary IMAQ driver VIs to do this part (be sure to download NI-IMAQ 4.1, I don’t think you’ll need the other stuff).
Big thanks to Alessandro. His instructions, documented in his VIs, are exceptional.
