    Summary form only given. This paper proposes an approach to path-planning around smooth obstacles that exploits visually derived geometry. A moving robot can scan the silhouette or apparent contour of an obstacle and estimate a minimum length path. This is done by seeking geodesics which can be extrapolated smoothly, around the obstacle and towards the goal. Preliminary implementation of this idea... View full abstract»

    Summary form only given. The ESPRIT project VIEWS (Visual Inspection and Evaluation of Wide-area Scenes) [project 2152] demonstrates computer vision systems for real-time surveillance of outdoor dynamic scenes in constrained situations. Two domains, viz. ground traffic at airports and road traffic have been selected for demonstration. For applications within these domains, inspection refers to a m... View full abstract»

  • Trinocular active range-sensors

    Publication Year: 1991, Page(s):4/1 - 4/4

    The principle of trinocular stereo is well known in the domain of passive devices and also has application in active metrology. Trinocular active devices have the advantage of freedom from mechanical scanning, and rapid image capture compared with more conventional active designs based on scanning laser stripes. Their efficient operation relies, however, on a good solution to the correspondence pr... View full abstract»

  • Recognition of parametrised models from 3D data

    This paper describes work done as part of the Oxford AGV project towards recognition of classes of objects encountered in a factory environment. The authors address the problem of recognising an object from range-data observations as an instance of a parametric model class, and determining the values of the class parameters for that instance of the model, and the pose of the object. They represent... View full abstract»

  • StereoDROID

    Stereo and structure-from-motion processing are combined in an attempt to overcome the disadvantages of each. The absolute base-line provided by the separation of the stereo cameras enables the speed-scale ambiguity to be resolved, and the long base-line resulting from processing a long image sequence enables good long-range accuracy to be obtained. StereoDROID is an approach to stereo structure-f... View full abstract»

  • The growth of modern interferometry for industrial inspection

    Publication Year: 1991, Page(s):3/1 - 3/4

    Two major developments in interferometry are discussed. One is the availability of cheap reliable He-Ne lasers, which have replaced expensive, unreliable and unwieldy sources with a device with is compact and cheap. The most recent product, coherent laser diodes, give extremely robust and reliable sources in a very small semiconductor package. The other development is the growth of computer techno...

  • Active stereo vision and its application to industrial inspection

    The use of active stereo as a means for collecting vision data has many advantages, especially when dealing with a relatively constrained environment found with indoor applications. These environments have several factors that enable simplifications to vision systems to be made. The first is that the lighting can be controlled, or at least is known about and can be reliably predicted. This enables... View full abstract»
