Time-lapse Videos of Assembling a Motion Capture System

The following videos show the process of assembling a 12 camera Optitrack Flex 13 system. We originally got the system little over a year ago at which time I created a number of videos showing the process, see the following blog post.

This blog post follows on from my previous post which included quite a number of photographs showing the process of assembly.

The first video below was recorded at 1fps, hence is running at 25x real-time speed. It shows the mounting of the cameras, the wiring of the up to the capture workstation and their repositioning with respect to the capture volume. You may also spot the setting up of a 5.1 Speaker System (Logitech Z906), that can output 500 watts of auditory bliss.

Two days later I got around to tidying some things up and calibration of the system. With the system fully operation and tested out all that was remaining was to tidy up the cables and make everything good and neat.

If you want to see a faster version of the first video above then this one below run at about 60x real-time and is a little under 3.5 minutes in length.

This very first assembly video created in September 2012 has received 1812 views to-date. As you can see it was setup in a much smaller room than in the videos above. Consequently the effective capture volume was limited to a cylinder of just a feet. If you like a spot of Vivaldi with your time-lapse videos this you may enjoy taking a look.

The following playlist includes over 40 videos documenting the process of setting up the MoCap system.


Computing Open Day RGU Summarised in Video

The following video will give you some small sense of what it was like today during our Open Day at the School of Computing Science and Digital Media, Robert Gordon University, Aberdeen, Scotland. It was held from about ten o’clock in the morning until three in the afternoon. After a half-hour registration period, visitors were treated to a welcome talk and a short series of lectures. Following on from this a number of hour long workshops were held on such topics as iPhone programming, cryptography and wireless networks. Their was also time to have a chat with Academics and see some of the demonstrations we had running throughout the day, most of which may be seen in this video. As you can see in some segments we were piping a video feed of the demonstrations happening in other rooms into one of our PC labs and projecting them for all to see.

Demonstrations included the use of an Eye Tracker to identify the area on screen a person was focusing on. A full body Motion Capture System comprising of a twelve camera Flex 13 system from Optitrack was also available to see in action. In concert with this we also had a motion tracking demo running on a Microsoft Kinect for windows, though the students who were doing the video recording didn’t get any footage of this. Also demonstrated was the Microsoft Surface (Samsung SUR40) which supports up to 52 points of interaction concurrently. If you watch all the video you may see that we certainly came close to this maximum value. All in all everybody seemed to enjoy the day visitors, staff and student helpers alike. Our next open day will be in a months time, at which point we hope to have a far larger and wider set of demonstrations to show the visitors to the school. See my YouTube Channel for further videos of some of the equipment seen here in this video.

Chris Young another member of staff at the School also grabbed hold of a camera and quickly recorded some of footage from of the Motion Capture System in operation. For more videos from Chris take a look at his Vimeo Channel.
