A wild idea that I don't have the knowledge to pull off...
Has anyone created a pair of cameras whose distance can be varied? (For example, a motor shifts the distance between the two cameras.)
If a computer knows the distance between its two cameras, it might be able to make a 3-d map of the surface of an object. The varying distance between the cameras would help with further objects -- or with closer, small objects.
@Chip_Unicorn Usually 3D camera setups - even if they are not made for human entertainment media consumption - are setup and calinrated for a fixed lens distance.
I've not seen setups that do vary this whilst working and at best you might find some scientific setups aimed at research with like eyetracking and stuff, but those are like custom rigs that cost several thousands if not millions.
Espechally since variance goes against calibration accuracy and usually a higher accuracy is desireable.
@Chip_Unicorn That being said it is possible in theory and I did see some practical applications, like clip-on lenses for #Xbox360#Kinect sensor bars so people can play closer to the sensor and in a tighter playspace than it was designed for.
OFC the opposite is also possible tho optically more challenging - not to mention that artificially increasing the playspace needed for the Kinect doesn't have any advantages except requiring more movement and poorer movement detection...
@Chip_Unicorn But yeah, that "Range Imaging" has been done and in fact I've seen some 3D scanning with Kinect Modules that provided blind people with acoustic heatmaps for rooms and hallways.
Tho having a #Kinect strapped to their face was considered not socially acceptable even before the rise of the #Glasshole|s despite said Kinect sensor not being used to record anything but only scanthe envoirment for obstructions.
