Uses the target for photogrammetry and the target for this photogrammetry the photogrammetry

摘要

PROBLEM TO BE SOLVED: To obtain a photogrammetry target whereby an inclination amount to a horizontal face can be measured when the target is set. ;SOLUTION: Three point power sources 16, 18, 20 are set at an equilateral triangular target 10, defining a reference plane. The target 10 is provided with an X-axis directional inclination sensor 22 and a Y-axis directional inclination sensor 24 for measuring inclination angles of two axes orthogonal to each other to a horizontal plane. Moreover, a geomagnetic direction instrument 26 is provided for measuring an azimuth. Measured inclination amounts and the azimuth are displayed at a display panel 28.;COPYRIGHT: (C)1998,JPO
