To provide a marking system and a marking method that can perform marking work more easily and improve marking work efficiency.SOLUTION: By specifying a direction of a surveying instrument 3 with respect to a laser marking device 2, an external control unit 54 calculates a first relative angle α which is a relative angle with the surveying instrument 3, calculates a second relative angle β which is a relative angle with a target line Lt, based on design drawing information, calculates a difference angle γ between the first relative angle α and the second relative angle β, and projects marking laser light onto the target line Lt by rotating a marking laser irradiation unit 11 for the difference angle γ.SELECTED DRAWING: Figure 2 【課題】より簡単に墨出し作業を行うことができ、墨出しの作業効率を向上させることができる墨出しシステム及び墨出し方法を提供すること。【解決手段】外部制御部５４が、レーザ墨出し器２に対する測量機３の方向を特定することで測量機３との相対角度である第１相対角度αを算出し、設計図情報に基づき目標ラインＬｔとの相対角度である第２相対角度βを算出し、第１相対角度αと第２相対角度βとの差分角度γを算出して、当該差分角度γ分墨出しレーザ照射部１１を回転させることで、目標ラインＬｔに墨出しレーザ光を投影する。【選択図】図２
