  • An on-line integrated industrial inspection system for the lighting industry

    Publication Year: 1991, Page(s):8/1 - 8/4

    Presents a set of knowledge-based algorithms suitable for on-line inspection, with particular reference to lamp inspection problems for the lighting industry. The system was developed to identify not only uncut wires, but also many other faults, such as missing solders on connector pads, insufficient soldering, and solder splashes on the backing disc. The paper describes the problem and identifies... View full abstract»

  • Determining the location of components in an AMP environment

    Publication Year: 1991, Page(s):7/1 - 7/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (200 KB)

    The manipulation of components by a robot in an automatic manufacturing process (AMP) requires knowledge about each component's location and orientation. A 3-D representation of the robot's workspace is thus required. In the work presented the 3-D representation is built up using information obtained from robot mountable CCD cameras positioned around the workspace. Each camera is connected to a tr...

  • An edge detecting image sensor architecture

    Publication Year: 1991, Page(s):4/1 - 4/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (152 KB)

    A programme of work at Brighton Polytechnic has concentrated upon the development of binary sensors featuring low to medium spatial resolution, with a view to their application to flexible industrial automation. The programme began with the in-depth study of the IS32, a member of the family of proprietary Optic DRAM (ODRAM) devices from Micron Technology. This was basically a modified 64 kbit dyna...

  • The binary Hough transform-theory, real time implementation and application to visual inspection

    Publication Year: 1991, Page(s):1/1 - 1/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (204 KB)

    The binary Hough transform (BHT) as well as its implementation and applications to visual inspection have been briefly presented and discussed. It has been verified that it provides some interesting features and could be an effective option for application in visual inspection and to produce the representation of the digital images by endpoints of its straight line segments to be used for posterio...

  • Automated identification of shoe upper components

    Publication Year: 1991, Page(s):10/1 - 10/5
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (176 KB)

    The ultimate application had not been fixed when the project started, but it was considered likely the vision would be used to sort shapes from a random selection into kits for producing batches of, say, two dozen pairs of shoes. For use in control of subsequent processes such as automatic stitchmarking, the vision must determine the position of each point in a shape to within one hundredth of one... View full abstract»

  • High performance character recognition for off-line handwritten British postcodes

    Publication Year: 1991, Page(s):6/1 - 6/5

    Provides details of a dictionary search scheme which efficiently improves the overall postcode recognition rate. The research described has shown that it is possible to extract high word recognition rates from an unoptimised character recognition algorithm, by using contextual knowledge. A basic character recognition rate of 63.1% was achieved for the full alphanumeric character set, as written in... View full abstract»

  • A tracking vision sensor system

    Publication Year: 1991, Page(s):3/1 - 3/5
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (168 KB)

    The initial aim was to develop a nontactile scanner capable of tracking a weld seam during robot welding operations. In addition, it was intended to investigate AGV guidance and surface inspection applications. The scanner is based on the `flying spot' principle as described by Batchelor et al. (1985), with a low power helium-neon laser scanned across the work-piece by means of a mirror rotated at... View full abstract»

  • Use of colour for image segmentation in the graphic arts

    Publication Year: 1991, Page(s):9/1 - 9/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (184 KB)

    It has been shown that colour selective masking can be a powerful technique for constructing masks for segmenting images in graphic arts applications. Perceptual colour coordinates allow a more effective specification of regions of colour space than printing ink densities. The colour selective methods can be provided along with other conventional feature extraction methods as graphical `tools' in ... View full abstract»

  • A low-cost robot guidance vision system

    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (104 KB)

    Describes some of the technology underpinning a new generation of systems. The sensor is attached to the robot, such that it is parallel to the welding torch or other tool, via an additional rotary axis allowing independent control of the sensor viewing direction. Operating on the basis of triangulation with a laser stripe, the sensor returns a standard video signal to the sensor controller. The s... View full abstract»

  • High performance classifier architectures for binary image processing

    Publication Year: 1991, Page(s):2/1 - 2/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (120 KB)

    Adaptability and high performance are prerequisites for cost-effective automatic industrial inspection and other product handling systems. The specification of appropriate systems therefore demands the development both of high performance algorithms and efficient techniques for implementation, together with a means of matching algorithms and implementational infrastructure. Transputer arrays offer... View full abstract»
