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.

On the other hand the SPC 900nc is an amazing camera for its price it performs at its stated specs that is 640×480 at 30fps, but dont be fooled into thinking that the camera actually does 60 or 90fps; anything greater than 30fps is achieved through interpolation, and in an MT scenario this is pretty useless.

In comparison of the 2 the spc900nc isnt as sensitive to IR as the xbox 360 vision cam, but can get the job done nicely. Where it lacks in IR sensitivity it makes up in FPS.

All in all the both cameras are awesome, with the vision camera being just $10 on ebay it cant really be beat for prototyping purposes, and if you only plan to use the cam only at 320×240 then then this camera cant be beat, it does 50+fps without interpollation, and has amazing IR sensitivity, what more do you want really? right? However if you want to use the camera at higher resolution than this, than this camera really isnt designed for it, and as a result isnt well suited for MT applications, it just cant give you the required fps needed. In that case the philips spc900nc would be the better choice.

This is my 2 cents worth of review/comparison of the two, im sure there are ppl out there that have their own opinion on the cameras, this is just mine.

    Hey! I’ve recently been looking into the possibility of building a MT table for personal use. My question is this: is it necessary for your IR camera to have resolution similar to or equal to that of your display, or will a low-res camera still work well enough? Obviously a 320×240 resolution wouldn’t be very accurate when used with a 1920×1080 display, but what about lower resolutions like 1024×768? Thanks!

      actually you’d be surprised at how good it’ll work… truthfully speaking i use 320×240 res for my 1600×1400 display and i can say for sure its more than enough for what you need. obviously if you are planing on using fiducials than they’ll have to larger or you’d need to use a greater resolution, even then you wouldnt need to go above 640x480res. It really all depends on how well you calibrated your screen, and the calibration algorithm being used in the tracker.
