Stereo-vision

Hello,
i saw examples about pluging a camera to the beagle board
is it possible to plug 2 cameras ? and use opencv

i also want to use speech recognition like cmusphinx

is it feasible ?
can the beagle board handle all this ?

thx

Any possibility that you could let everyone know which BeagleBoard you have? There are four different boards.

Hi,

is it possible to plug 2 cameras ? and use opencv

In our project [1] we were able to encode two 320x240 frames sticked
together side by side from two USB cameras on BBxM (using DSP encoder)
and send encoded frames to PC. On PC two frames were decoded and used
to create anaglyph image as described here [2] (using OpenCV). So in
general it is doable but the frame-rate we achieved was about 15FPS
and depending on the stars constellation in the sky :slight_smile: the USB
subsystem might work or might crash under rather heavy load from two
USB cameras plus network traffic.

Hi,

You may be able to, but depending on framerate and other operations it could cause issues with usability.

Other solutions on similar platforms like this one and this one have dedicated boards to handle the image processing and synchronization (if you’re doing stereo vision).

I wish you luck with your project!
