  • Patent number: 11625868
    Abstract: A centerline for generating network data of an indoor space can be generated while limiting the amount of calculation. Points where first straight lines and second straight lines constituting centerlines meet are created using re-entrant vertices (Step 1). The points created in Step 1 are connected by lines (Step 2). Connection lines corresponding to the longest sides are repeatedly deleted from closed polygons defined by the connection lines obtained in Step 2 until no closed polygons are left (Step 3). Each vertex of the connection lines obtained in Step 3 is connected to a farthest center point on the perimeter of the shape of the passage if there is such a farthest center point to which the vertex can be connected without touching the perimeter and without crossing other connection lines (Step 4).

  • Publication number: 20220205801
    Abstract: It is possible to display the state of the current route even with a large change in visual field in an easy-to-understand manner. A grouping unit (102) groups a plurality of nodes included in a route on a map into groups having no change in line-of-sight in an order of travel direction on the route. A point generation unit (103) generates, for each of the groups grouped by the route grouping unit, a plurality of points included in a route of the group so that the route is divided into smaller sections by the points from a start point of the group toward an end point of the group. A viewpoint determination unit (104) determines, for each of the plurality of points, a viewpoint in accordance with a condition of the point. A walk-through display unit (105) performs walk-through display for displaying a scenery corresponding to the determined viewpoint.
