To provide a three-dimensional surveying device, a three-dimensional surveying method and a three-dimensional surveying program capable of more surely acquiring dimensional data concerning a characteristic part of a measuring object.SOLUTION: A three-dimensional surveying device 2 includes: a collimation distance measuring unit 4, a scanner unit 5, and a control calculation unit 46. A control arithmetic part 46 includes the steps of: acquiring, based on a survey result of the collimation distance measuring unit 4, three-dimensional data related to a characteristic part of a measuring object which exists between a plurality of three-dimensional data included in the point group data acquired by a scanner unit 5 and in which the three-dimensional data is not acquired by the scanner unit 5; and executing the control for adding the three-dimensional data related to the characteristic part of the measuring object acquired on the basis of the survey result of the collimation distance measuring unit 4 to point group data acquired by the scanner unit 5.SELECTED DRAWING: Figure 1 【課題】測定対象物の特徴部分に関する３次元データをより確実に取得することができる３次元測量装置、３次元測量方法および３次元測量プログラムを提供すること。【解決手段】３次元測量装置２は、視準測距ユニット４と、スキャナユニット５と、制御演算部４６と、を備える。制御演算部４６は、スキャナユニット５により取得された点群データに含まれる複数の３次元データの間に存在する測定対象物の特徴部分であって３次元データがスキャナユニット５により取得されていない測定対象物の特徴部分に関する３次元データを視準測距ユニット４の測量結果に基づいて取得し、視準測距ユニット４の測量結果に基づいて取得した測定対象物の特徴部分に関する３次元データをスキャナユニット５により取得された点群データに追加する制御を実行する。【選択図】図１
