To provide a survey system which can obtain a product of a three-dimensional survey with higher accuracy.SOLUTION: A survey system (1,1',1") comprises: a movable body (2); a scanner (3) having: an emission section (3a) which emits distance measurement light (3h'); a light receiving section (3b) which receives the reflected distance measurement light (3l'); a distance measurement section (3c) which performs distance measurement on the basis of an output of the light receiving section; a first optical axis deflection section (3f,3 g) which is disposed on an optical axis (3h) of the distance measurement light and deflects the distance measurement light; a second optical axis deflection section (3j,3k) which is disposed on a light receiving optical axis (3l) of the reflected distance measurement light and deflects the reflected distance measurement light at the same deflection angle and in the same direction as in the first optical axis deflection section; and an emission direction detection section (3 m) which detects the deflection angle and direction of the first optical axis deflection section and the second optical axis deflection section; a posture detector (5,13) which detects a posture of the scanner; and a position measurement device (4,20) which measures a position of the scanner.SELECTED DRAWING: Figure 8
