i am looking for references that discuss digitizing
3d objects. ideally if one knows of an article, or
articles, that describe the construction of a 3d
digitizer i would like to hear about it.
thanks in advance

Here are a couple of survey papers on 3D sensing (often called range sensing). Range sensors produce a `depth map' rather than in `intensity map'; I assume that's what Vince is after. Besl, P., ``Active Optical Range Imaging Sensors'', in Advances in Machine Vision, J. Sanz (ed.), Springer-Verlag, 1989. Besl's article is an overview of the different range sensing techniques (time-of-flight, AM, FM, triangulation, Moire techniques, shape-from-focus, etc.), and contains an extensive bibliography. Here are two more surveys: Jarvis, R., ``A Perspective on Range Finding Techniques for Computer Vision'', IEEE Trans. PAMI, v5, n5, 9/83, 505-512. Nitzan, D., ``Three-dimensional Vision Structure for Robot Applications'', IEEE Trans. PAMI, v10, n3, 5/88, 291-309. Also, there was a workshop on range image understanding here at MSU last spring. The proceedings will be published by Springer-Verlag later this year. A summary of the workshop appears in the journal Machine Vision and Applications, pp. 45-60, 1989. ------------------------------------------------------------------------------ Pat Flynn, CS, Mich.
