A brief Comparison Between Xbox360 Vision Cam Vs Philips SPC900NC

Monday, 1 September, 2008 § 2 Comments

On the surface at first the the xbox360 cam looks great and works well in an MT scenario, it by far has the best IR sensitive CCD chip on borad, and performs extremely well in MT scenarios when used at 320×240 resolution, you can easily achieve 50+ fps. However where the camera lacks is in its 640×480 resolution range it barely does 17fps, usually it satys between 11~15fps and with that the cpu usage also skyrockets. « Read the rest of this entry »

BandPass Filter Lens Attachment

Thursday, 3 July, 2008 § 3 Comments

Well recently i’ve had a lot of requests on how i’ve attached my BP filter to my camera… so i thought i might as well post a write up…

Note: in the pitures i’m using the original focus lens that came with the camera but this method could also be employed with a wide angel lens or a fisheye lens. Also it this technique can employed with any camera that has a manual focus lens. For fisheye or wide angle lens your bandpass filter need to be at least 30mm in diameter.

Wide Angle Lens for the Xbox360 Live Vision Cam.

Wednesday, 18 June, 2008 § 2 Comments

Recently i purchased a wideangle (120degree viewing angle) lens for the xbox360 vision cam… from an ebay store the lens came well packed and was delivered to me in 5 days.

At first looks the lens looks perfect, it fits snugly into the xbox360 vision cam holder and is able to focus the picture perfectly. but on closer inspection, as you will see that he holder is not perfectly centered to the ccd chip on the on the camera pcb, as a result the 2 top corners are not fully visible.

New IR Pass lens

Saturday, 14 June, 2008 § 2 Comments

Well in my recent testing i found out the IR bandpass lenses i bought were to narrow for my setup…. so therefore i got a new lens from Omega labs’s ebay store. The lens i got was a 880BP86 it is a much wider frequency pass to allow more of the IR emitters light to pass through at the same time block light from the visual spectrum. however since is a wider BP filter i fear that more noise will be detected by the ccd chip from natural light… but further tests will reveal that.

For the past few weeks i’ve been doing my research into multitouch, and the various types of cameras used by people over at NUIGroup.com, as their IR sensors. I narrowed my choice to 2 the Phillips SPC900-NC and the Xbox360 Live Vision Camera. By seeing a few tests Daddyoli did and and the recommendation of the Xbox360 Vision Cam given to me by both Daddyoli and Fairlane. I went with the Xbox360 Live Vision Camera.

I purchased it for just over $13CAD from an excellent seller at ebay. For $13 the camera proved to be well worth the money. And the IR filter was easily removed. Below are the steps i performed to get the camera to work in an FTIR setup. (Basically its the removal of the IR Filter).
