These are electric arc furnaces that produce couple of hundred tons of molten steel (3000 F) every few hours and the people concerned want to move their sensors as far away as they possibly can. I would appreciate any views/advice/warnings/EXPERIENCE that anyone on the net has to offer. Pointers to relevant references or equipment will also be welcome. The following is a summary of the application and problems we foresee, o We want to sense the position of large (10 ft), slow moving objects (~ 1 ft/sec) with reasonable accuracy (~1 inch). These items are, the roof of a furnace, the tilt angle of the furnace etc. o Light conditions are extremely variable. There is an order of magnitude change (at least) when the furnace lid is opened. Lots of shadows etc. o Lots of dust, vibration and sparks flying about are to be expected. o The temperatures may be rather high (100+ F). This requires that cameras be decently far off. o Processing should be completed in less than 5 seconds. Thanks a lot, Rajan p.s.: If you need further details to answer anything PLEASE contact me. -- "Until the philosophy of one race superior, and another, inferior, is finally and permanently discredited and abandoned, it's WAR.

The Solid Modeller represents curve surface as a set of facets which can be displayed on the screen or printed. What I am trying to do is to write a translator to transform the output data into the real from, e.g. cyclinder. Could anybody give me some pointers about the existing work or any publications ? Thanks in advance. guanghua [ I believe the work on Acronym and Successor by Binford and his students at Stanford has addressed this? phil... ] ------------------------------ End of VISION-LIST ********************
