Summary:To provide a vertical measurement system and a reference point tracing method, capable of vertically tracing a reference point with high accuracy.SOLUTION: A vertical measurement system 1 comprises: a surveying device body 7 having a surveying device provided at a reference point P rotatable in a horizontal direction; a target device 3 installed at a site where the reference point P is transferred; a display unit; and a guide terminal 5. The target device 3 has a target 4 that emits target light toward the surveying device body 7. The surveying device body 7 comprises a collimating image light receiving unit that collimates the rotational axis direction of the surveying device body 7 to acquire an image of the target 4, and an arithmetic control unit. The arithmetic control unit is configured to calculate a position of a rotational axis from the trajectory of the image of the target 4 obtained by rotating the surveying device body 7, and transmit position information on the image of the target 4 and position information on the rotational axis to the guide terminal 5. The guide terminal 5 displays a position of the target 4 and a position of a zenith on the basis of the position information on the image of the target 4 and the position information on the rotational axis.SELECTED DRAWING: Figure 1 【課題】基準点の鉛直トレースを高精度に行える鉛直測定システム及び基準点のトレース方法を提供する。【解決手段】水平方向に回転可能な基準点Ｐに設けられる測量装置を有する測量装置本体７と、基準点Ｐが転写される部位に設置されるターゲット装置３と、表示部と誘導端末５とを具備する鉛直測定システム１であって、ターゲット装置３は測量装置本体７に向ってターゲット光を射出するターゲット４を有し、測量装置本体７は、測量装置本体７の回転軸心方向を視準し、ターゲット４の像を取得する視準像受光部と、演算制御部とを具備し、演算制御部は、測量装置本体７を回転して得られるターゲット４像の軌跡から回転軸心の位置を演算し、ターゲット４像の位置情報と回転軸心の位置情報とを誘導端末５に送信する様構成され、誘導端末５はターゲット４像の位置情報と回転軸心の位置情報に基づきターゲット４の位置、天頂の位置を表示する。【選択図】図１
