To provide a surveying device and a surveying device system with which it is possible to locate a measurement object at high speed.SOLUTION: The surveying device comprises: a distance measuring light emission unit for emitting distance measuring light; a light-receiving unit 22 for receiving reflected distance measuring light that is the distance measuring light retroreflected by a measurement object and background light that enters coaxially with the reflected distance measuring light; a distance measurement unit for receiving the reflected distance measuring light and measuring the distance; an image capturing unit for receiving background light separated from the distance measuring light and capturing a background image; an optical axis deflection unit 37 for deflecting the optical axis of the distance measuring light and the optical axis of the background light integrally; and an arithmetic control unit for controlling the optical axis deflection unit. The optical axis deflection unit includes a pair of disc prisms in which a plurality of prism columns are arrayed in parallel, a rotation drive unit for rotating the disc prisms individually, and an emission direction detection unit for detecting the angle of rotation of each disc prism.SELECTED DRAWING: Figure 2 【課題】高速度で測定対象を視準可能な測量装置及び測量装置システムを提供する。【解決手段】測距光を射出する測距光射出部と、前記測距光が測定対象で再帰反射された反射測距光と、該反射測距光と同軸で入射する背景光とを受光する受光部２２と、前記反射測距光を受光し測距を行う測距部と、前記反射測距光から分離された背景光を受光し、背景画像を取得する画像撮像部と、前記測距光の光軸と前記背景光の光軸を一体に偏向させる光軸偏向部３７と、該光軸偏向部を制御する演算制御部とを有し、前記光軸偏向部は複数のプリズム柱を平行に配列した一対のディスクプリズムと、該ディスクプリズムを個別に回転させる回転駆動部と、前記各ディスクプリズムの回転角度を検出する射出方向検出部を有する。【選択図】図２
