Model-based object recognition is typically addressed by first deriving structure from images, and then matching that structure with stored objects. While recognition should be facilitated through the derivar tion of as much structure as possible, most researchers have found that a compromise is necessary, as the processes for deriving that structure are not sufficiently robust. We present a technique for the extraction, and subsequent recognition, of 3-D object models from passively sensed images. Model extraction is performed using a depth from camera motion technique, followed by simple interpolation between the determined depth values. The resultant models are recognised using a new technique, implicit model matching, which was originally developed for use with models derived from actively sensed range data [1]. The technique performs object recognition using secondary representations of the 3-D models, hence overcoming the problems frequently associated with deriving stable model primitives. This paper, then, describes a technique for deriving 3-D structure from passively sensed images, introduces a new approach to object recognition, tests the approach robustness of the approach, and hence demonstrates the potential for object recognition using 3-D structure derived from passively sensed data.
