Automatic generation of a road map of a site can be performed. Data records collected by vehicles with a GNSS-positioning system while driving are provided, each data record having a position information representing a two-dimensional or three-dimensional position of the vehicle, an identification reference specific to a corresponding vehicle, a time tag, and a heading information. The data records are assigned to corresponding trips based on the time tag and the identification reference. The trips are mapped within an area and the area is divided into a plurality of uniform tiles. For each tile, a heading information variance of the data records covered by the respective tile is determined. A tile is defined as junction tile, if the tile has a heading information variance higher than a computed threshold variance. An area of interest (AoI) having a perimeter is determined by which a plurality of junction tiles is surrounded.
A method and system for automatically generating a road map of a construction/mining site is provided. Position, vehicle identification, time tag and heading data is collected from vehicles circulating on the site. Trips records are formed according to vehicle identification and time tag data. The trips records are mapped within an area of the site. The area is divided into a plurality of tiles that each have a calculated heading information variance. When a tile has a calculated variance greater than a threshold variance, the tile is defined as a junction tile. Areas of interest having respective perimeters are identified as a function of the number of junction tiles in particular areas of the site. The perimeters have multiple entry and exit boundary points. By clustering the boundary points, entry and exit transition points are identified. A graph of the road map is built by connecting the transition points.
A system for determining an object position on a site with large machinery, particularly a mine site, a construction site, or an agricultural area, based on radio frequency time-of-flight ranging. The system is configured to determine a current position of a reference point indicative of a position of a machine on the site, to access an arrangement dataset indicative of a positional relationship between the reference point and a mounting location on the machine of at least one anchor of a point-to-point radio ranging unit, and to determine a position of the at least one anchor based on the current position of the reference point and the arrangement dataset, wherein the position of the at least one anchor is provided to a position determining unit configured for determining position information of tags based on ranging data of the point-to-point radio ranging unit.
