Stereophotographic process and processing apparatus for producing works of sculpture

摘要

The present invention is related to the provision of an improvement in a process for producing works of sculpture on the basis of a stereophotographic process by arranging a plurality of photogrpahic cameras and a plurality of optical projectors, each being loaded with a transparent screen having a plurality of parallel lines therein, around an object to be photographed at a predetermined object distance, arranging another plurality of projectors operatively around a mass of material to be modeled at such an operative distance of projection that they may be located in a similar position to that of each of the cameras to project the screen therefrom onto the object to take a photographic picture of a striped pattern in the screen projected onto the object, loading the projector with thus-taken picture to be projected onto the mass of material to be modeled, and modeling manually the mass of material to make the projected lines meet and coincide with each other as appeared thereon and to obtain a similar sized sculptural work to the object; a procsss for producing works of sculpture on a reduced scale which comprises the steps of setting to reduce distance of projection and a focal length of each of the lenses of the plurality of projectors directed to the object and loaded with the picture accordingly to the desired scale of reduction with respect to the object to be sculptured, and preparing the picture of striped pattern projected upon the object to be reduced accordingly to the scale of reduction to be loaded onto the projector.
