The first one, having a working distance of 15 cm to 100 cm, with a field of view of approx. 45 deg. and weighing 1.2 Kg, is intended to be mounted on a PUMA-760 robot for telerobotics research applied to live line maintenance and repair. The other one, more compact and with a much smaller work distance, will be mounted on a custom designed 6 dof robot which itself is mounted on a rail for turbine blade repair. I am looking for information and/or references on: 1) Sensor positioning and mounting on the robot. I expect difficulties with the sensor and wires causing limited robot movements, etc. 2) Hand-Eye calibration algorithms for this type of sensor. Are there any techniques developed to accurately link the sensor reference frame to the robot reference frame? Any good practical algorithms would be welcome.

Here at Essex we do a lot of work on coding moving sequences, packet video and the like, and we have recently looked at similar equipment. Our choice came down to two: 1. the Abekas A60 (which we eventually chose and with which we're very satisfied). This is based on two parallel transfer discs and holds 30 seconds worth of digital video as luminance/chrominance (the latter sampled at half the rate, as you'd expect). There's also a four-disc system which holds 60 seconds. The A60 expects to input CCIR601-format video, but Abekas sell the A20, which converts RGB to CCIR601 in real time. Just plug them together and you're away. The A60 outputs CCIR601, RGB or lum/chrom. In terms of display, the system is limited to the size of a standard TV frame (575x768), though you can load and read smaller frames if you want. The A60 is hosted off Ethernet and supports rcp, rsh, etc, which makes it easy to transfer image data to/from it. The main disadvantage is that it's very noisy -- keep it in a soundproofed room or invest in some ear plugs at the same time. In the UK, Abekas is at Portman House, 12 Portman Road, Reading, Berks, RG3 1EA. Tel: +44 734-585421. Fax: +44 734-597267. They don't do educational discounts (boo, hiss). 2. DVS of Hannover (Abekas is US/UK, incidentally) sell a RAM-based system which is more flexible (in terms of image sizes) than the A60. However, when I looked at them, they couldn't hold anything like as much as the A60 and were somewhat more expensive. I don't have any info to hand, not even an address, but I believe their systems came in VME cages, so you stand a chance of interfacing one to a SparcStation. Dunno about drivers, though. If interested parties want to contact DVS, mail me and I'll have a look for their address. Adrian F.

AAAI-90 WORKSHOP ON QUALITATIVE VISION July 29, 1990 Boston, MA Qualitative descriptions of the visual environment are receiving greater interest in the computer vision community. This recent increase in interest is partly due to the difficulties that often arise in the practical application of more quantitative methods. These quantitative approaches tend to be computationally expensive, complex and brittle. They require constraints which limit generality. Moreover inaccuracies in the input data do not often justify such precise methods. Alternatively, physical constraints imposed by application domains such as mobile robotics and real-time visual perception have prompted the exploration of qualitative mechanisms which require less computation, have better response time, focus on salient and relevant aspects of the environment, and use enviromental constraints more effectively. The one-day AAAI-90 Workshop on Qualitative Vision seeks to bring together researchers from different disciplines for the active discussion of the technical issues and problems related to the development of qualitative vision techniques to support robust intelligent systems. The Workshop examines aspects of the methodology, the description of qualitative vision techniques, the application of qualitative techniques to visual domains and the role of qualitative vision in the building of robust intelligent systems. ------------------------------ Date: Tue, 14 Aug 90 07:41:38 bst From: eba@computing-maths.cardiff.ac.uk Subject: NEW JOURNAL -SYSTEMS ENGINEERING- SPRINGER VERLAG Organization: Univ. of Wales Coll. of Cardiff, Dept. of Electronic & Systems Engineering **** NEW JOURNAL *** NEW JOURNAL *** NEW JOURNAL *** NEW JOURNAL **** ----------------------------------------- [ JOURNAL OF SYSTEMS ENGINEERING ] [ SPRINGER - VERLAG - INTERNATIONAL ] ----------------------------------------- AIMS AND SCOPE The Journal of Systems Engineering will be a refereed academic journal which publishes both fundamental and applied work in the field of systems engineering.
