Abstract
“M-3”is a affin plotter made by K. K. Sokki-Sha for the purpose of teaching stereo-photogrammetry in senior high-school. In M-3 vertical movement of the floating mark relative to a model point is excuted by vertical movement of photographs instead of by that of the floating mark.
However, it is quite doubtful that this construction of M-3 gives better results, since it leads to very complicated model deformation.
In this paper theoretical treatment of this deformation is given, and numerical results will be reported in the following paper.
