Hi folks,

I am a bit out of my element in this newsgroup, since my background is 
graphics, but you have the collective knowledge I need.

I want to build an augmented reality system that integrates computer graphics 
with real-life video.  To integrate the two convincingly I need depth 
information for the video.  As far as I can tell I have two options:

1. Infer depth via stereo matching. 

2. Measure depth with a Laser Range Finder.

Constraints are as follows.  Resolution of the depth map should be about 
500 by 500 pixels, but can probably drop to 100 by 100.  Depth range is
ohh say from .2m to 10m with accuracy of +-0.01m.  Depth measurements per
frame cannot take longer than 100 milliseconds on a Sparc10 type machine.

Would a Laser Range Finder solve my problems?  Do you have pointers to 
literature describing such beasts. 

What are good journals/conferences etc to look at for fast stereo vision 
algorithms that solve my problems? 

Please email or post responses as appropriate.
Thanks,
Matthias
