Document Type and Number:
Japanese Patent JP7335780
Kind Code:
B2
Abstract:
Provided is a laser scanner combined with an electronic level without a reduction in effective irradiation range. A laser scanner S includes an electronic level unit 8 including a telescope and a level housing 20, being configured to acquire an image of an leveling staff LS collimated with the telescope and to measure a height of and a distance to the leveling staff, a distance measuring unit 36 for performing distance measurement by emitting distance-measuring light and receiving reflected light from a measurement target, a turning mirror 35 for rotating and irradiating the distance-measuring light in a vertical direction, a vertical rotation driving unit 33 for rotating and driving the turning mirror 35, and a horizontal rotation driving unit 15 for integrally rotating and driving the electronic level unit 8 and the scanner unit 9 in a horizontal direction. The scanner unit 9 configured to acquire an instrument height by irradiating a ground surface with the distance-measuring light while acquiring point cloud data by scanning the distance-measuring light in a measurement range. The turning mirror 35 has a rotation axis arranged parallel to a collimation optical axis A of the telescope.
