The european DMA machine, provides at more than 1 Hz stereo and 3D-reconstruction from 3 cameras for an indoor scene from 0.5 to about 5 meters. With temporal data fusion, and sensor precise calibration the precision is better than 1%. A few prototypes are now under final check.

Phone: (415)328-8886 Us-Mail: Teleos Research, 576 Middlefield Road, Palo Alto, CA 94301 Date: 23 Apr 91 16:28:51 GMT From: tnaka@ius3.ius.cs.cmu.edu (Tomoharu Nakahara) Does anyone know the high-performance, practical, realtime stereo system which uses only cameras? And I want to know the processing time and the range resolution of the system. Thanks in advance. You might be interested in the PRISM-3 system that we have developed at Teleos Research. It implements the sign-correlation algorithm I developed at MIT some years ago for doing binocular stereo and optical flow measurement. It is a self contained system composed of an active stereo camera head with pan, tilt, and vergence control and a desktop VME box. The box includes digitizers, video rate Laplacian of Gaussian convolvers (with kernel sizes up to 60 by 60 pixels), a high speed correlator (36 parallel correlation measurements in 100 microseconds with thousand point windows), a motor controller board, and a dedicated 68030 control processor. The box can operate on its own or as a measurement server via ethernet to a workstation. We recently completed the first prototype system and it performs at a rate of about 100 range or velocity meaurements per video frame time (30ms). We expect this to improve substantially as we get the control software tuned. We have been getting disparity resolutions between 1/3 and 1/10 pixel depending on noise levels. I can send you more details if this is of interest to you.

We will be grateful of your information. My research interest is object recognition. I developed a method to match general 3D free form surfaces (Stein & Medioni IUW90, Stein & Medioni CVPR91). We have quite a few models (also different views). Most of them are busts of composers. We obtained them with a liquid crystal range finder.

We will be grateful of your information. Try using a ray-tracer to produce an image of a 3D environment, then work backwards. Advantages: * Complete control of 3D environment (and ACCURATE knowledge of object positions. * Complete knowledge of the 3D/2D conversion matrices. * An ability to model your detection system ruggedness amidst a variety of noise models (which can be applied to ANY stage of the 3D/2D conversion). Disadvantages: * Reflection models (Lambertian, Phong, etc.) are empirically applied in most of the ray tracers I know about -- they may not be sufficiently accurate for your needs. * The noise/sampling models used are again empirically applied with the criteria for correctness being "If it look more 'REAL', its better". Again, this may not be acceptable to you. An excellent book on reflection models is by Roy Hall, and was published last year (I think, I can't remember the title, but its in the FAQ in comp.graphics). Of course, I haven't really answered your question, since in the end your system still has to work in the real world, but its enough to get 3/4 of the bugs etc. out of the way - and in a completely controlled environment. PS. There was a discussion on this subject a week or two ago in comp.graphics.

Arps, IBM Almaden Research Center; William K. Pratt, Sun Microsystems, Inc. Cochairs: Myron D. Flickner, IBM Almaden Research Center; Robert M. Haralick, University of Washington During the past few years there have emerged two important trends in the implementation of image processing systems. First, is the creation of a new generation of image processing chips, which offer an astonishing degree of capability in small packages at relatively low cost. Second, is the development of standards for image processing and interchange. These implementation trends are likely to profoundly affect the design of the next generation of image processing systems. This conference will seek to cover both hardware and software. In the hardware area, surveys will be given on the capabilities and functionalities of programmable and fixed function, VLSI image processing chips that have recently been introduced. The theme of this area will be exploration of how the availability of such chips will affect the design of future image processing systems. In the software area, surveys will be presented on the emerging dejure software standards being developed by the International Standards Organization and the X Consortium, as well as defacto standards such as TIFF for image transport. The theme of this area will be how these software standards will affect the design of image processing systems, with emphasis on the development of associated software development tools and graphical user interfaces. The conference will bring together individuals who are concerned with the implementation of image processing and interchange systems from both hardware and software perspectives. Papers are solicited on the following and related topics: * programmable and fixed function image processing and interchange chips * image processing hardware architectures and systems * image processing and interchange standards * image processing software architectures and systems * image processing software tools and utilities (including compilers, graphical user interfaces, and image data base systems) ------------------------------ Date: Mon, 29 Apr 91 00:55:46 EDT From: Dr Kevin Bowyer <kwb@midgit.csee.usf.edu> Subject: IEEE Workshop on Directions in Automated CAD-Based Vision IEEE WORKSHOP ON DIRECTIONS IN AUTOMATED CAD-BASED VISION Sunday-Monday, June 2-3 Maui Marriot (location of CVPR '91) Revised Preliminary Program General Chairman Program Chairman Linda Shapiro, Univ. of Washington Kevin Bowyer, Univ. of South Florida Program Committee Avi Kak, Purdue University Joe Mundy, General Electric C.R.&D.

Spatial Vision has been in existence for six years, and is publishing its fifth volume. I have decided it's time for a new Editor-in-Chief for the Americas, and will resign at the end of this year. David Foster is still Editor-in Chief for Europe etc., so continuity will be maintained. I am happy to report that our recommendation to the Board and the Publisher for a replacement has been accepted with enthusiasm. The new Editor for the Americas will be Adam Reeves, of Northeastern University. Formally his appointment will start with Volume six, but he will be ready to accept papers for review from June 1st 1991. Let me urge you to support Adam, and the Journal; the best way of doing so is to submit papers at your earliest opportunity! Peter Dodwell Co-Editor-in-Chief Spatial Vision PS. If you want more information about Spatial Vision, let me know. I have some informative brochures for distribution.
