An important computer vision task in robotics is modeling of 3D objects in a robot's
workspace. This paper presents a method for generating octree models of 3D solid objects
from their silhouettes obtained in a sequence of images. The silhouettes of objects which are
projected into an image and the center of projection of the image generate 3D conic
volumes. A 3D model of the objects is iteratively constructed by intersecting such conic
volumes obtained from a sequence of images. Hierarchical octree structures are used to …
