This site describes our experience and results on how to assemble
a device to do wireless local network stereoscopic mobile video acquisition,
transmission and display. It includes software and hardware description
as well as a prototype.
Currently we are able to capture a stereo par with resolution of 640x480
per frame and transmit it over wireless networking with up to 22 frames
per second. The system is assembled in a backpack weighing about 3Kg
and there is also a helmet where the cameras are mounted. The prototype
can be carried around, acquiring and transmitting stereo video. The
data is compressed using JPEG algorithm, transmitted over Wi-fi using
IEEE 802.11 wireless protocols and then received in a client node,
where the stereo video can be visualized.
Future developments include MPEG compression protocol, increased frame-rate
and higher resolution for the system.
Stereoscopic video has been widely studied over the past years.
But only recently stereoscopic digital video acquisition has become
less complex to implement. With the advent of wireless network devices
with bandwidth capabilities of supporting video data, it is now
possible to implement real time stereoscopic video acquisition and
transmission over local wireless network.
Mobile wireless stereoscopic video transmission in WLANs has not
been studied in enough depth as far as the researchers are aware
of. Because of the lack of these types of experiments, this work
in intended as a report of our experiments, problems encountered
and solutions to some of the problems.
