Claim 0:
1. A point cloud data acquiring method, comprising:
measuring, using a ranging sensor, a plurality of azimuths and distances from the ranging sensor to a plurality of planimetric features configuring a traveling environment of a vehicle of the point cloud data acquiring system, and acquiring point cloud data representing the plurality of azimuths and distances;
detecting, using a magnetic sensor, a plurality of magnetic markers laid in or on a traveling road of the vehicle, each of the plurality of magnetic markers being a magnetism generation source;
reading, using an RFID (Radio Frequency IDentification) tag reader, from a plurality of RFID tags, unique information of each of the plurality of magnetic markers, each of the plurality of RFID tags being attached to each of the plurality of magnetic markers, each of the plurality of RFID tags being configured to provide the unique information of a magnetic marker of the plurality of magnetic markers to which the RFID tag is attached; and
recording, using processing circuitry, in a memory, the point cloud data by linking each data representing azimuth and distance of the plurality of azimuths and distances with (1) marker reference information including the unique information of each of the plurality of magnetic markers, and (2) relative position information representing a relative position of the vehicle with reference to each of the plurality of magnetic markers.
