Post subject:  Would markers help?

Hi there.

So, I know part of the point of this is to use standard web cams without need for markers. But would markers help the process be more accurate? Would the system be better able to track the small nuances of movement? Or perhaps better track really high speed athletic motions? Just curious.

thanks
David

Our technology is very different from marker-based systems. Adding markers would mean designing a completely different system.

Good marker-based systems like Vicon have very high-res cameras and therefor are capable of tracking small nuances of movements.

For tracking really high speed athletic motions, you just need cameras with good sensors, like Logitech QuickCam Pro 9000, to minimize motion blur. Markersless mocap systems are generally believed to be good at tracking large motions like athletics. See http://en.wikipedia.org/wiki/Motion_capture#Optical:_Markerless
