Recovering Three-dimensional Structure from
Motion with Surface Reconstruction
ELLEN C. HILDRETH,*t HIROSHI ANDO,:~ RICHARD A. ANDERSEN,§I[ STEFAN TREUE§¶
Received 9 April 1993; in revisedform 3 March 1994
This paper addresses the computational role that the construction of a complete surface representation
may play in the recovery of 3-D structure from motion. We first discuss the need to integrate surface
reconstruction with the structure-from-motion process, both on computational and perceptual grounds.
We then present a model that combines a feature-based structure-from-motion algorithm with a
smooth surface interpolation mechanism. This model allows multiple surfaces to be represented in a
given viewing direction, incorporates constraints on surface structure from object boundaries, and
segregates image features onto multiple surfaces on the basis of their 2-D image motion. We present
the results of computer simulations that relate the qualitative behavior of this model to psychophysical
observations. In a companion paper, we discuss further perceptual observations regarding the possible
role of surface reconstruction in the human recovery of 3-D structure from motion.
