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. |
