Description of simple method in 3D reconstruction in medical imaging

The aim of this study is to present research made in a 3D scanner conception of a human foot. The first step of foot reconstruction is treated. The cloud number points is increased thanks to a combination of several methods. The first method for the first points extraction is explained. The relative length, height and width of the object are obtained in order to construct the parallelepiped including the foot. All parallelepiped points are virtually assigned to foot points. Each image is projected in the volume in the different planes of the views in order to eliminate the exterior points. From the volume of all these points only the points of the surface are retained. The points of the cloud should be located on or outside the surface of the foot. This reconstruction must be ameliorated by an active triangulation. We use the tools of matching points of stereovision in the image profiles.
