Abstract: A map update system includes a map data storage unit storing therein map data. The map update system acquires a position of a road marking painted on a surface of a road. The map update system acquires a determination value to be subjected to determination of blurring of the road marking based on at least either of measurement information on the road marking and analysis information analyzing the measurement information. The map update system compares the determination value to a reference value and acquires blur information indicating a degree of blurring of the road marking. The map update system reflects the blur information in the map data.

Abstract: In a map data generation apparatus, probe map data is generated for each of data management units corresponding to (i) road sections, (ii) road links, or (iii) meshes into which a map is divided, based on a plurality of probe data collected from a plurality of vehicles. Difference data are obtained by comparing basic map data with the probe map data; the basic map data is updated based on a plurality of difference data, for each of the data management units. A transient data is discriminated from data corresponding to the probe data or the difference data; the transient data is excluded from the data.

Abstract: A road map generation system is provided that collects camera image data of road conditions captured during traveling of vehicles on roads and generates road map data based on the camera image data. The system performs image processing on the collected camera image data to convert into orthographic images and to combine the orthographic images to generate a combined image. The system extracts a defective portion of a road marking on a road from the combined image and performs a determination of whether the defective portion of the road marking is due to noise at the image processing of the image processing device or there is a defect in the real world. When the defective portion of the road marking is due to the noise at the image processing, the system performs a correction process of the road marking.

Abstract: A map data storage device, a map data updating method, and a computer program that can shorten the time required for a map data updating process. In the case where map data stored in a navigation-side local DB of a navigation apparatus are to be updated, the navigation apparatus updates the map data stored in the navigation-side local DB on the basis of map updating data received from a map distribution center, and prepares a data reference index that associates a PID (universal identification information) included in the map data with a record number (internal identification information) included in the map data on the basis of the updated map data. After that, in the case where an application is executed by the navigation apparatus, the prepared data reference index is referenced to access the map data stored in the navigation-side local DB.

Abstract: In a probe data evaluation apparatus, probe data are collected from a vehicle. Provisional map data are generated based on the collected probe data. The generated provisional map data are compared with reference map data, to provide a comparison result. Whether or not to adopt the collected probe data is determined based on the comparison result.
