Point cloud data processing method and point cloud data processing device
Abstract:
A trajectory of a measuring device is calculated based on measurement data acquired by the measuring device that is moving along a measurement route, and on a vertical plane orthogonal to the trajectory, a two-dimensional figure is identified by designating an extraction angle range around an intersection of the trajectory and the vertical plane based on a perpendicular drawn down to a horizontal plane from the intersection and an extraction distance range based on the intersection on the vertical plane, and a region obtained by extending the two-dimensional figure along the trajectory is set as an extraction region, and point cloud data in a region including a specific analysis target is extracted as extracted point cloud data from entire circumference point cloud data acquired by scanning the circumference of the measuring device and included in the measurement data.
