METHOD GENERATING TERRAIN DATA FOR GLOBAL PATH PLANNING

摘要

The present invention relates to a method for generating topographical analysis information for global path planning for an unmanned vehicle. The present invention includes: a step of dividing a pre-determined region into multiple areas by using multiple virtual grids; a step of generating the topographical analysis information composed of the areas, wherein any one among the areas includes GPS information on the area and a speed range the unmanned vehicle can have in the area; a step of modifying the speed ranges included in the areas based on an aerial photograph taken of the pre-determined region; a step of collecting driving data with respect to at least one among the areas; and a step of modifying the speed ranges included in at least some among the areas based on the collected driving data. According to the present invention, it is capable of generating the accurate topographical analysis information even on an inexperienced region by using an FDB and the aerial photograph. In addition, the present invention can generate the topographical analysis information on an experienced region more accurate than that on the inexperienced region by using the actual driving data.
