Abstract
The present invention provides a moving body map information display system that is capable of extracting and displaying the desired map information correctly and easily without changing the transition point and the route that have been set by an operator. A limited region map information generation device, that is provided for extracting the map information of only the limited region based on the route point coordinate information of a map that is stored in a memory medium. The device includes the road information to thereby generate the limited region map information, includes a route generation capability for generating a moving body route based on the route point coordinate information, the road information, and various display parameters.
Claims14
A moving body map information display system comprising:
- means for generating a set of route point coordinate information for indicating points on a transition route and a scheduled route of a moving body;
- means for generating and extracting a plurality of limited region map information, said limited region map information based on said route point coordinate information that is stored in a memory medium and includes a plurality of road information to thereby generate the limited region map information;
- means for storing said limited region map information;
- and
- means for displaying said stored limited region map information,
- wherein said means for generating said limited region map information further includes
- means for generating a moving body route based on said route point coordinate information and said road information,
- means for setting map scale, wherein scale magnitudes of a plurality of strip-like regions of map information located along said moving body route varies along said moving body route, and
- means for extracting said strip-like regions based on said scale magnitudes.
A moving body map information display apparatus for a vehicle comprising:
- a display unit;
- an input unit;
- a global positioning system for providing a plurality of coordinate data for said vehicle;
- a plurality of memory units for accomodating a required system memory;
- a central processing unit for generating a moving body route and extracting a plurality of limited region map information based on route coordinate points of said vehicle, wherein said limited region map information includes strip-like regions of map information based upon said moving body route, said strip-like regions having scale magnitudes set in order to limit said required system memory below a memory capacity of said memory units;
- an interface circuit;
- an input/output bus;
- and
- a map information supply apparatus for providing a plurality of map information for the moving body route for said vehicle, said map information supply apparatus connected through said interface circuit to said input/output bus.
