  • Patent number: 9098745
    Abstract: In the case of collecting samples, it is difficult to select a representative point of a target area. Thus, the samples are collected from certain positions, resulting in generation of variations of data. The target area is specified on an image to extract features from the target area. Further, clustering is performed for the features on a feature space to obtain representative features, and the obtained representative features are extracted as sampling points.

  • Patent number: 7930100
    Abstract: In order to quickly update map data in region units without generation of contradiction to adjacent non-updated regions after the updating, under map data updating, time and date of updating of update region of a terminal is obtained with designation of a region as the update object used as a trigger, a mesh ID on the external boundary of the partial update region is obtained, and the differential updating data ID of the updated differential updating data is also obtained from the terminal. The partial updating data and differential updating data required for updating of the designated region of the terminal are selected from the information obtained above and these selected data are applied to the map data of terminal. When updating is conducted using the partial updating data and differential updating data, the time and date of updating of the relevant partial update region ID are changed and the differential updating data ID is registered to the differential management data.

  • Patent number: 7839306
    Abstract: A map display method whereby the contents of a road map displayed can be easily and clearly grasped regardless of the running conditions of a vehicle. In a summarized map displayed on a display screen 10, an area including a vehicle position 11, a destination 13 and a guide route 12 between them is displayed in simplified fashion. At a position far from the destination, as shown in FIG. 2A, a summarized map of a wide area is displayed and objects including a road 14 and a facility 15 are limited to a greater degree. With the approach of the vehicle position 11 to the destination 13, as shown in FIG. 2B, the contraction scale is decreased and a summarized map of a middle area is displayed, while at the same time increasing the objects displayed. With a further approach of the vehicle position 11 to the destination 13, as shown in FIG.
