SYSTEM AND METHOD FOR 3D PHOTOGRAPHY AND/OR ANALYSIS OF 3D IMAGES AND/OR DISPLAY OF 3D IMAGES

摘要

When 3D viewing means become much more available and common, it will bevery sad that the many great movies that exist today will be able to be viewedin 3Donly through limited and partial software attempts to recreate the 3D info.Filmstoday are not filmed in 3D due to various problems, and mainly since a normalstereo camera could be very problematic when filming modern films, since forexample it does not behave properly when zooming in or out is used, and it cancause many problems when filming for example smaller scale models for somespecial effects. For example, a larger zoom requires a correspondingly largerdistance between the lenses, so that for example if a car is photographed at azoomfactor of 1:10, the correct right-left disparity will be achieved only if thelensesmove to an inter-ocular distance of for example 65 cm instead of the normal6.5 cm.The present invention tries to solve the above problems by using a 3D camerawhichcan automatically adjust in a way that solves the zoom problem, and provides asolution also for filming smaller models. The angle between the two lenses ispreferably changed according to the distance and position of the object thatis at thecenter of focus, and changing the zoom affects automatically both the distancebetween the lenses and their angle, since changing merely the distance withoutchanging the convergence angle would cause the two cameras to see completelydifferent parts of the image. The patent also shoes that similar methods canbe usedfor example for a much better stereoscopic telescope with or without a varyingzoom factor. In addition, the patent shows various ways to generateefficiently a 3Dknowledge of the surrounding space, which can be used also for example inrobotsfor various purposes, and also describes a few possible improvements in 3dviewing.
