1. A computer-implemented method for object localization comprising:
- providing a plurality of tags having fixed positions within an environment and known identifications;
providing a reader, for detecting the tags and reading the identifications, wherein the reader detects a plurality of tags within a scanning volume having a known shape, wherein the scanning volume comprises one or more ellipsoid-shaped volumes;
determining a subset of the plurality of tags within the scanning volume; and
determining a position of the reader according to the subset of the plurality of tags within the scanning volume and the known shape of the scanning volume.

Abstract
A computer-implemented method for object localization includes providing a plurality of tags having fixed positions within an environment and known identifications, and providing a reader, for detecting the tags and reading the identifications, wherein the reader detects a plurality of tags within a scanning volume having a known shape. The method further includes determining positions for the plurality of tags within the scanning volume, and determining a position of the reader according to the positions for the plurality of tags within the scanning volume and the known shape of the scanning volume.

9. A system for tracking comprising:
-
a coordinate system of tags within an environment, each tag having a known identification and a known fixed position; and a reader for detecting the identifications, wherein the reader detects tags within a scanning volume having a known shape, the reader determining its position according to the known fixed positions of the tags and the known shape of the scanning volume, wherein the scanning volume comprises one or more ellipsoid-shaped volumes. - View Dependent Claims (10, 11, 12)
