Visual Hull

[asda333]

Hi

Anyone have any experience of how to build the visual hull using opencv and c++

I have calibrated the camera and don't know what should be the next step.

Soo many questions? so hopefully one by one.

I know that silhouette carving is where you capture different views of the object and convert them to silhouette, i hope they don't have to be calibrated because i don't how, and then i have to build a bounding box made up of voxels nxnxn, and project each voxel to all silhouettes and if its is in all silhouettes then leave it else carve or if it is partially split it using octrees and then repeat.

first question, how do i build a bounding box made up of voxels and project each voxel on to a silhouette and check if it is in or out.

do i use opengl?

thanks
