Yes its possible, you need software to compute depth from stereo images. Ive searched furiously and found only the SVS software from Videre design.

They want $600 and the examples look decent, Im just itching to buy it once I get $600 lying around. If you got plenty cash then use The Foundrys Furnace plugin called zdepth $4400.
If anyone knows other alternatives please let us know.
