  • Publication number: 20230358550
    Abstract: A computer-implemented system and method distilling three-dimensional structure to a two-dimensional raster with multiple discrete planes for purposes of safe and accurate route planning including a map generator, pixel encoder, map transformer, and route generator. The map generator generates a raster map by populating a blank map canvas with raster and vector data on a per-pixel basis and obtains values for pixels from the pixel encoder. The pixel encoder encodes type, plane, and elevator information of features into pixels. The map transformer converts the map produced by the map generator into a weighted graph of nodes and edges suitable for route generation. The route generator generates routes using the graph produced by the map transformer.

  • Patent number: 11105643
    Abstract: A method and system for generating tactical routes includes an intervisibility database pre-populated with pre-computed optical lines of sight between locations or nodes in geographic terrain, an intervisibility analyzer for analyzing propagation of the pre-computed optical lines of sight between the locations or nodes in the geographic terrain, a speed analyzer for analyzing speeds of travelers across the locations or nodes in the geographic terrain, a cost generator for generating a blended cost grid using said intervisibility and speed analyses, and a route generator for generating routes that facilitate tactical movement based on said blended cost grid. The route generator computes intervisibility unions at the locations or nodes in the geographic terrain and minimizing intervisibility unions along the generated route.

  • Patent number: 8818710
    Abstract: The present invention is a computer-implemented system for providing guidance information to aid a user in traveling along an off-road route. This system assumes that the route has already been determined. Also, it is assumed that the user's position and orientation can be determined, for example using existing techniques such as the global positioning system (GPS). The present invention uses a Look-Ahead-Point Finder (100) to find a point, which we refer to as a look-ahead point, located on the route ahead of the user's current location. A Guidance Message Constructor (102) and a Guidance Presenter (106) are used to present the user with guidance information directing him towards the look-ahead point. If the user is already headed towards the look-ahead point, then a Turn Analyzer (108) is used to search the route in order to find the next turn location.
