matlab - 3D reconstruction with only stereo pair of images and no calibrated camera -
i have 2 spatial images have no camera calibration input. how can develop 3d model reading both images using imread? tried follow code needs camera parameters too.

i tried come 3d sparse modelling doesn't work.
http://in.mathworks.com/help/vision/examples/sparse-3-d-reconstruction-from-two-views.html
can use gaussian filters or input image data stereo pairs , match them dept estimation. if depth can make 3d model.
please suggest can done fast running out of time.
firstly, don't need in terms of 3d model. need euclidean model (i.e. know lengths of sides? ) or scale (metric reconstruction)?
secondly know images ? taken same camera @ different time points ? different cameras ? how cameras arranged ? there special cases may make 3d recovery easier in general case not able metric reconstruction without camera calibration.
having said try reading this paper on calibration vanishing points or this one
it's possible, if know type of cameras, has got calibration parameters enough - defending on quality of cameras.
the geometry behind not trivial , need know more before recommending solution.
