python 2.7 - convert depth map (resulting from photometric stereo) to 3d mesh -

i'm woking on project regarding 3d reconstruction. obtained depth map photometric stereo method. now, want do, convert depth map 3d mesh can visualise on meshlab example. can tell me how can ? ps : i'm working python ! thanks

this not trivial exercise doable. basic steps are:

• use dense depth map generate voxel representation
• construct isosurface voxel model using e.g. marching cubes algorithm

take @ paper 1 possible approach though it's far best way this: https://www.academia.edu/6148442/3d_reconstruction_on_a_mobile_device in particular pp43-45 onwards

(disclosure: it's mres thesis).
