APPARATUS AND METHOD FOR MEASURING RADIUS OF CURVATURE BY USING GYRO/ACCELERATION SENSOR TO SECURE THREE-DIMENSIONAL CONTINUITY TEST/UNDERGROUND GEOGRAPHIC INFORMATION

摘要

According to the present invention, an apparatus for measuring a radius of curvature by using a gyro/acceleration sensor, which is an apparatus for measuring a radius of curvature of an underground conduit, comprises a casing (120), a gyro sensor (130), an acceleration sensor (140) and a calculation part (150). The casing (120) is in contact with the inner wall of an underground conduit (300) and has at least two pairs of guide ski plates (110) approaching/spaced in a central axial direction. The gyro sensor (130) includes an X-directional gyro sensor (Gyro_X), a Y-directional gyro sensor (Gyro_Y) and a Z-directional gyro sensor (Gyro_Z), which are positioned inside the casing (120). The acceleration sensor (140) includes an X-directional acceleration sensor (Acc_X), a Y-directional acceleration sensor (Acc_Y) and a Z-directional acceleration sensor (Acc_Z). The calculation part (150) receives an input of detection data on the gyro sensor (130) and the acceleration sensor (140) to calculate the radius of curvature of the underground conduit (300). Therefore, according to the present invention, when a radius curvature of an underground conduit is measured, the underground conduit can be three-dimensionally measured based on X, Y and Z axes by using a gyro/acceleration sensor, and an underground geographic information system can be easily constructed.;COPYRIGHT KIPO 2017
