    The ultimate goal of this research is to design a system to automatically learn a visual domain so that it can subsequently execute a controlled navigation from any location to another when instructed to do so. The required system must have: flexibility, autonomy, scalability and robustness, which is defined for clarity. It must be flexible in order to cope with a broad range of problems, for exam...

    High integrity castings require surfaces free from defects to reduce, if not eliminate, vulnerability to component failure from such as physical or thermal fatigue or corrosion attack. Previous studies have shown that defects on casting surfaces can be optically enhanced from the surrounding randomly textured surface by liquid penetrants, magnetic particle and other methods. However, very little h... View full abstract»

  • 3-D vision systems using rotating 1-D sensors

    Publication Year: 1995, Page(s):6/1 - 6/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (252 KB)

    This paper describes continuing research with both two-dimensional (2D) and three-dimensional (3D) rotating line-scan vision systems in industrial inspection and control automation. Traditionally, two-dimensional line-scan systems have been effectively used in a production line environment where movement is inherent in the application. However, when only using a single sensor, depth or range infor... View full abstract»

  • The application of parallel DSP networks to real time image processing

    Publication Year: 1995, Page(s):11/1 - 11/6

    Image processing, and especially real time image processing, is naturally a very compute intensive task. These tasks can now be tackled very well with the Texas Instruments TMS320C40 DSP processor. This, as well as having a powerful processing architecture well suited to data intensive signal processing tasks such as image processing, also has six high speed communication ports for transferring da...

  • Arc Weld Join Investigator

    Publication Year: 1995, Page(s):7/1 - 7/7
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (276 KB)

    The Are Weld Join Investigator will scan the join between two pieces of piping to produce dimensional data that will aid the welding of the join. The idea for the project came from ISOTEK, a Leeds firm who lay and maintain oil pipes in the North sea. When, for example, a section of piping needs to be replaced a join must be welded to secure the new piping to the old. The welding, using an arc, mus... View full abstract»

    Many materials are manufactured industrially in the form of a continuously moving strip or web; examples include metal strip (cold rolled, plated and stainless steel; aluminium), paper, glass, textile materials (woven, knitted and printed fabric; lace; carpet), etc etc. To ensure high product quality it is necessary to inspect visually,; this inspection can be automated using machine vision.

  • Recovery of the third dimension using a priori geometric knowledge

    Publication Year: 1995, Page(s):8/1 - 8/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (220 KB)

    The implementation of a real-time imaging system to support the robotic transfer of semiconductor wafers within an ion implanter is described. Since the system is to be embedded in a product, it must be economically viable, and therefore capable of being supported by an inexpensive computing platform. In practice, this can be achieved by exploiting the inherent constraints. In this application, a ... View full abstract»

    A general-scene object-oriented image coder is presented which can encode colour TV signals at low bit-rate independent of content, complexity, and temporal behaviour of the TV sequence. This is a novelty compared to object-oriented coders developed by other researchers which are specialised in video-phone scenes. For the realisation of the coder's generality, stereoscopic and motion information h... View full abstract»

    Over the past 20 years machine vision has grown from an infancy of exciting but mostly unrealisable prospects into a mature field in which sophisticated real-time systems can be installed economically in agricultural, industrial, medical, surveillance, transport and many other applications. In these areas it is commonly applied to active control, e.g. of guided vehicles and robots, but there are m... View full abstract»

  • Uncalibrated stereo vision for PCB drilling

    Machine vision systems are often used in conjunction with industrial robots to automate manufacturing operations. However, such automation is limited by the need for accurate calibration of both the robot and the vision system. This paper discusses how the mathematics of projective geometry may be used in conjunction with a model of the workpiece to avoid the need for camera calibration. This in t... View full abstract»

    Rapid advances in the automation of production methods have increased inspection requirements for three main reasons. Firstly, higher production speeds require higher inspection speeds. Secondly, the implicit inspection involved in manual production and assembly is no longer present and must be accommodated elsewhere and lastly, the ever-increasing demand of the customer for higher quality.
