Abstract: The invention provides a three-dimensional surveying instrument, which comprises a light emitter for emitting a distance measuring light, a light projecting optical unit for irradiating a distance measuring light from the light emitter along a distance measuring optical axis, a light receiving optical unit for receiving a reflection light from an object to be measured, a photodetection element for converting the reflection light as focused at the light receiving optical unit to an electric signal, a scanning unit for scanning a distance measuring light with respect to the object to be measured provided on a frame unit, angle detecting units for detecting an irradiating direction of the distance measuring light as scanned by the scanning unit, a vibration detecting unit for detecting vibration amount of the frame unit, and a control arithmetic unit having a storage unit where a threshold value is stored, wherein the control arithmetic unit controls so that the number of rotations of the scanning unit is gradually increased from low rotation number to the maximum rotation number, stores in the storage unit by associating the number of rotations with vibration amount as detected, compares vibration amount corresponding to the number of rotations as calculated based on measurement conditions with the threshold value, and performs measurement on the object to be measured in a case where it is judged that vibration amount corresponding to the number of rotations as calculated is lower than the threshold value.
