MANUFACTURE OF BIRD'S EYE VIEW OF REMAINS OR THE LIKE

摘要

PURPOSE: To give a drawing of buried cultural assets, remains, etc., for which a rough drawing is sufficient, within a short working time by setting a mark in the site and video tape photographing the site from just above the site by using a wireless operation aircraft for photographing. ;CONSTITUTION: At first, marks 1, 2 are set in several sites of a working site and at the same time a pole 3 is stood vertically in almost the center position of the working site. Then, using a wireless operation aircraft for photographing, the working site is video tape-photographed from just above the site. That the aircraft is positioned just above the site is confirmed by the fact that only the summit of the pole 3 is seen in the video tape image. Next, the optimum image is selected from the video tape images and printed up by a video printer which is previously brought to the working site. The printed up picture is then brought back to an office and after auxiliary lines 5, etc., are added to the picture, the resulting picture is processed by a digital copying machine and a digital copy 6 expressed by dotts is obtained.;COPYRIGHT: (C)1994,JPO&Japio
