摘要：

In this paper, a new method for three-dimensional object envelope construction is proposed using the chaining approach. The object is seen by three cameras placed on an orthonormal basis (OXYZ) axes. From these projections, respective contours are extracted and then transformed into a list of chains presenting contour pixels of each projection. These chains are restructured to be used for arbitrary object shape envelope construction. The constructed 3-D object can be viewed on the screen using perspective or parallel projections under arbitrary viewpoint angles θ and φ. A one-pixel precision is reached for recovered objects.
