TESTOMETRIC METHOD FOR OBJECT COORDINATE DETERMINATION Russian patent published in 1998 - IPC

Abstract RU 2115888 C1

FIELD: digital photogrammetry. SUBSTANCE: method includes alternate photographing on one stationary light-sensitive material positioned in left- and right-hand photographic cameras, object test with known coordinates of its nodes in system of coordinates of test and object to be examined. Method also consists in determination of space coordinates by interpolation relative to the nearest nodes of recovered test and object model. Test is colored dull black. Test nodes with light-pulse marks operating from one power supply source. Test is photographed against black background. Left- and right-hand combined pictures obtained are transformed into equivalent digital images which are introduced into computer alternately. Display screen shows volumetric stereoscopic model of test and object being examined. In case of stereoscopic examination only those nodes are considered on display screen which limit elementary link within range of which determined point is positioned. EFFECT: higher efficiency and accuracy.
