1. A laser surveying system comprising:
a rotational light emitting unit to rotationally emit a laser beam, comprising a case and a beam emitter supported on the case with an optical axis of the laser beam rotatable relative to the case, and an emit-side controller to acquire a rotational position of the optical axis of the laser beam relative to the case; and a light receiving unit to receive the laser beam from the rotational light emitting unit and perform surveying of a light-receiving position, the light receiving unit comprising a receive-side controller to:
acquire an angle of site of the laser beam relative to a reference plane including the optical axis of the laser beam,acquire a light shielding area in which the laser beam is blocked, wherein the light shielding area is defined by the rotational position and the angle of site, anddetermine whether or not the laser beam received by the light receiving unit has been properly emitted from the rotational light emitting unit on the basis of the rotational position, the angle of site, and the light shielding area. |
