Anyway, for the intended purpose, it's more than enough - though I sure would love to see MS someday opt for a true ToF camera.Carlos Martinshttps://www.blogger.com/profile/06977756139964818233noreply@blogger.comtag:blogger.com,1999:blog-506492938749742916.post-80063822809904523942011-08-24T12:39:14.092+01:002011-08-24T12:39:14.092+01:00But this is not true at all... Project Natal is no...But this is not true at all... Project Natal is not a TOF camera and it has nothing in common with RADAR, SONAR or LIDAR which are both based on TOF principles.<br /><br />This system works by projecting a pattern of infrared dots onto the imaging area, using a setup of cameras to detect the distortion of the patterns as it is received from a different angle.<br /><br />"Tricked" 3D image analysis and stereoscopic wizardry is exactly what it is, only well executed and quite fast.<br /><br />It also has no "modulated spectrum" tuning and can definetely be disturbed by other light sources. Flooding the room with infrared light would void the depth detection. Also, remote controls may distort or "blind" the depth perception in affected areas, as will very dark surfaces.Anonymousnoreply@blogger.com
