Abstract
A laser scanning system of the present invention includes a first rotation mechanism configured to perform a rotation in a predetermined first rotation axis and at a rotation speed around the first rotation axis as a rotation center; a first rotation speed control unit configured to control the rotation speed of the rotation in the first rotation axis by the first rotation mechanism, and a laser scanner device disposed on the first rotation mechanism, to be rotated together with and by the first rotation mechanism, and the laser scanner device including a laser distance measuring unit configured to emit a leaser and to measure a distance to a detection target, wherein the first rotation speed control unit is configured to make a control to the rotation speed of the rotation in the first rotation axis in a detection rotation angle range corresponding to an area in which the detection target is present and another control to the rotation speed of the rotation in the first rotation axis in a non-detection rotation angle range corresponding to another area in which the detection target is not present.
