Laser Scanner System And Registration Method Of Point Cloud Data

A laser scanner system comprising:

• a laser scanner which includes a distance measuring unit for emitting a distance measuring light, receiving a reflected light from an object to be measured, and performing a distance measurement, a scanning unit for rotatably irradiating said distance measuring light, a directional angle detecting unit for detecting an irradiating direction of said distance measuring light, a GNSS device and a control arithmetic unit, and a target which sets a back sight point, wherein said control arithmetic unit has a target scanning mode in which a target scanning is performed over a range including said target and a point cloud data measurement mode in which said distance measuring light is scanned to a measurement range and point cloud data is acquired, and is configured to calculate point cloud data with a global coordinate value and a global coordinate value of said target based on said global coordinate value obtained by said GNSS device, a measurement result obtained by executing said point cloud data measurement mode and a measurement result obtained by executing said target scanning mode.
