To enhance tlie applicability of the approach, we have developed a generalization of t.lie analysis that a) enables varying view direction, b) operates sequeiitially, while the sensor is in motion. and c) provides spatiallycoherent descriptions of observed ohjects. To achieve this grneralization it was necessary to develop an explicit. description of the evolution of images over time. This evolution produces two-dimensional manifolds in space-time - these represent explicitly both the spatial and temporal structure of the temporally-evolving imagery, and we term them spaliot~mporul surfaces. A battery ol hear sequential filters operates on these surfaces, tracking and estimating paramet.ers of features in the scene. The product of the analysis is a set of evolving three-dimensional contours describing the tliree-dimensional contours in the scene.

With the increasing demand for 3-D spatial information for tasks of passive navigation Generrgy 1980, Moravec 1980, automatic surveillance Henderson 1979, aerial cartography Kelly 1977, Panton 1978, and inspection in industrial automation, the importance of effective stereo analysis has been made quite clear. A particular challenge is to provide reliable and accurate depth data for input to object or terrain modelling systems (such as Brooks 1981b). This paper describes an algorithm for such stereo sensing. It uses an edge-based line-by-line stereo correspondence scheme, and appears to be fast, robust, and parallel implementable. The processing consists of extracting edge descriptions for a stereo pair of images, linking these edges to their nearest neighbors to obtain the edges to their nearest neighbors to obtain the edge connectivity structure, correlating the edge descriptions on the basis of local edge properties, then cooperatively removing those edge correspondences determined to be in error-those which violate the connectivity structure of the two images. A futher correspondence process, using a technique similar to that used for the edges, is applied to the image intensity values over intervals defined by the edge correspondence. The result of the processing is a full image array disparity map of the scene viewed. (Author)
