AR camera compass

with one comment

I added a simple compass  that I think will be helpful in our AR preview.

No changes in our previous code though. I still have to consider changes in the roll and pitch values.

and altitude as well..

Augmented Reality x-position

leave a comment »

Just updated our code for our camera mode. Our application can now identify POI’s within a 500 m radius. It will position our markers depending on the POI’s angle with the current Bearing. I just need to port this into an actual device to see if the markers match the building in the camera preview. By the way, the camera  preview is turned off in the preview above cause the moving checkered board annoys me.

Use Case Diagram

leave a comment »

This is the Use Case Diagram for my Augmented Reality Game. I am trying to scale it down as much as possible since we’ve only got less than 7 weeks before the semester ends. I’ve yet to find a name that fits my AR game’s description. 🙂

Sleepless Nights, Software Options and Project Demo

leave a comment »

Since Parallels Desktop is proprietary and I only have 13 days left before the trial key expires, I decided to switch back to VMWare. After all, VMWare’s much more stable in terms of hardware support than in VirtualBox.(Although, in Ubuntu, there exists a bug wherein you won’t be able to access the Mac folders) Also, I haven’t tested the iSight Driver on Windows XP using VMWare yet so I might as well try it.

JMF and NyARToolkit and Mac OSx

with 5 comments

After iSight worked on Parallels, I started installing Netbeans, JMF, and Java3D on Windows XP. Then I tried running NyARtoolkit for Java with the libraries I gathered earlier. However, the project always catches the exception ArrayIndexOutOfBoundsException 0>=0. It was pointing to the JMFCaptureDevice class. I figured that I should know the List of Capture Devices supported by JMF. So I stumbled upon this website where you could get all the list of supported captured devices by JMF on your laptop. So I compiled it, ran it, and it detected two audio devices.

Patay.

It was unable to detect the video capture.

I checked the JMFRegistry and looked for detected devices. Fortunately, a video capture device was detected. I rebuilt the project and… voila! NyARtoolkit worked.

Hardware Issues

with one comment

I think I may have been spending too much time focusing on my virtualization of Ubuntu that I’ve used up all my time reconfiguring and not doing my supposed tasks this vacation.

So far. These are the things that I’ve done with my Macbook.

  • Reinstalled Ubuntu thrice on my Virtualbox. (Problems found : (a.) uvcvideo was already installed but it still can’t detect iSight Camera; modprobe -r uvcvideo returned pipeline null. no camera found. (b) Installed isight-firmware-tools, copied AppleVideoUSBSupport on /lib/firmware, typed ift-extract /lib/firmware/AppleVideoSupport in terminal then rebooted; no camera found; (c) tried to let Ubuntu automatically detect iSight and reinstalled cheese, camorama, and Ekiga; Returned errors: No camera found and cannot find device on /dev/video0)
  • Installed iSight driver on Windows XP but
  • Downloaded and Installed VMWare on Laptop, installed Ubuntu twice on it. Downloaded and installed all Package updates. Same procedures done with Virtualbox. (Problems found : (a.) uvcvideo was already installed but it still can’t detect iSight Camera; modprobe -r uvcvideo returned pipeline null. no camera found. (b) Installed isight-firmware-tools, copied AppleVideoUSBSupport on /lib/firmware, typed ift-extract /lib/firmware/AppleVideoSupport in terminal then rebooted; no camera found; (c) tried to let Ubuntu automatically detect iSight and reinstalled cheese, camorama, and Ekiga; Returned errors: No camera found and cannot find device on /dev/video0)

My other options include using my old Acer 4520 machine(which I’ve already tested on Windows and NyARtoolkit worked) and to reformat my Macbook and dual-boot with Ubuntu and MacOSx. I think it has virtualization issues that’s why I can’t connect with VMWare or Virtualbox.

I’ll be reformatting my laptop a little later so I’d be able to start my 3D modelling afterwards.

*edit*

Another option that I can do is to buy another webcam. Actually it’s the most feasible option I can think of right now. Costly yet might be effective. I’m still on the process of designing and finalizing my game board, however, my main priority is getting my hardware working..
