Abstract
A map information processing device according to the present disclosure comprises: a point cloud map acquisition unit that acquires a point cloud map; a survey map acquisition unit that acquires a survey map including the contour of a structure; a boundary contour extraction unit that creates a closed curve of the boundary of the structure from the survey map; and a structure point cloud extraction unit that extracts, as a structure point cloud, a remaining point cloud obtained by removing a point cloud within the closed curve of the boundary of the structure from the point cloud map.
Claims9
A map information processing apparatus comprising:
- a point cloud map acquisition unit configured to acquire a point cloud map;
- a survey map acquisition unit configured to acquire a survey map including boundary information on a structure;
- a boundary contour extraction unit configured to create a structure boundary closed curve from the survey map;
- and
- a structure point cloud extraction unit configured to extract a point cloud by an inside/outside determination as to whether the point cloud included in the point cloud map exists either inside or outside the structure boundary closed curve, and classify the extracted point cloud into a structure point cloud.
