I am a newbie and would like to take your guidance to proceed in my project

A brief description of my project

-An object will be placed on the stage which rotates slowly and every time it rotates an image is taken,image will have only black and white colors that is the background will be white and the object will be black color My task is to get the vertex array and then detect the shape -second task would be to convert all the the 2d vertex array to a 3d object Limitation : Object might not have sharp edges and there might be chances of dust particles stuck to the surface of object

I would like to know how to proceed in my approach -My plan of action as of now is first subtract the stage data to get the object and then apply approx poly to get the vertex array.(My confusion is if i would be able to get edges accurately) -I do not know if this is the right place to ask for the second part of the project that is convert 2d array to 3d model but any guidance would be of great help.

i have attached a sample image for clearer understanding

Look up examples and tutorials on Structure from Motion (SfM), and know that there are two major approaches; one from a fixed camera and moving object, and another from a moving camera imaging fixed objects.

Any progress so far?
