Electronic systems for locating objects

摘要

A database for a set of orientation-matched road (OMR) sections is searched according to a calculated orientation of an object and orientations of road sections stored in the database. The OMR sections are searched for a position-matched road (PMR) set according to a calculated position of the object and positions of the OMR sections. The PMR set includes one or more PMR sections. The object is located using the PMR set.

主权项

1. A computer-implemented method for locating an object, said method comprising:
searching a database for a first plurality of orientation-matched road (OMR) sections according to a calculated orientation of said object and orientations of road sections stored in said database; searching said first plurality of OMR sections for a first position-matched road (PMR) set according to a calculated position of said object and positions of said OMR sections, said first PMR set comprising at least one PMR section; locating said object using said first PMR set; and performing operations if the number of PMR sections in said first PMR set is greater than two, said operations comprising:
discarding information for said first PMR set;searching said database for a second plurality of OMR sections;searching said second plurality of OMR sections for a second PMR set; andlocating said object using said second PMR set.
