摘要

A method for determining the shape and the dimensions of a two-dimensional, a perspective view of distorted image (1) of a three-dimensionally firmly defined origin element (2), the standing upright and of a frame forming the basis of calculation of a predetermined width a and a predetermined height h is limited, starting from a fixed observation point (k), characterized by the steps of:Positioning of two measuring rods (5, 6) at the location of the vertically extending sides of the rectangular frame and marking (a, b) of the height h of this frame on the measuring rods (5, 6),Measuring of the horizontal angle α from the observation point (k) for marking (a) on the observation point near measurement bar (6),Measuring of the horizontal angle β from the observation point (k) for marking (b) on the observation point remote measurement bar (5),Measuring of the vertical angle k ∠ {right arrow a from the observation point (k) for marking (a) on the observation point near measurement bar (6),Measuring of the vertical angle k b from the observation point (k) for marking (b) on the observation point remote measurement bar (5),Calculating the..
