Abstract

Temporally parsed data regarding at least a first item is captured (101). This temporally parsed data comprises data that corresponds to substantially simultaneous sequential samples of the first item with respect to at least a first and a second different points of view. Conditional probabilistic analysis of at least some of this temporally parsed data is then automatically used (102) to disambiguate state information as pertains to this first item. This conditional probabilistic analysis comprises analysis of at least some of the temporally parsed data as corresponds in a given sample to both the first point of reference and the second point of reference.

Claims

1. A method comprising:

capturing temporally parsed data regarding at least a first item, wherein the temporally parsed data comprises data corresponding to substantially simultaneous samples of the at least first item with respect to at least first and a second different points of reference;

automatically using, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data as corresponds in a given sample to;

the first point of reference; and

the second point of reference;

to disambiguate state information as pertains to the first item.

2. The method of claim 1 wherein capturing temporally parsed data comprises, at least in part, capturing the temporally parsed data using at least two cameras that are positioned to have differing views of the first item.

3. The method of claim 1 wherein automatically using, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data comprises, at least in part, using conditional probabilistic analysis with respect to state information as corresponds to the first item.

4. The method of claim 1 wherein automatically using, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data comprises, at least in part, determining whether to use a joint conditional probabilistic analysis or a non-joint conditional probabilistic analysis.

5. The method of claim 1 wherein automatically using, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data comprises determining whether to use the conditional probabilistic analysis for all of the temporally parsed data as corresponds to the given sample.

6. The method of claim 1 wherein:

capturing temporally parsed data regarding at least a first item, wherein the temporally parsed data comprises data corresponding to substantially simultaneous samples of the at least first item with respect to at least first and a second different points of reference comprises capturing temporally parsed data regarding at least a first item and a second item, wherein the temporally parsed data comprises data corresponding to substantially simultaneous samples of the at least first item and second item with respect to at least first and a second different points of reference; and

automatically using, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data to disambiguate state information as pertains to the first item comprises automatically using, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data to disambiguate state information as pertains to the first item from information as pertains to the second item.

7. The method of claim 6 further comprising:

automatically using, at least in part, disjoint probabilistic analysis of the temporally parsed data to disambiguate state information as pertains to a given one of the points of reference for the first item from information as pertains to the given one of the points of reference for the second item.

8. The method of claim 6 wherein the conditional probabilistic analysis of at least some of the temporally parsed data to disambiguate state information as pertains to the first item from information as pertains to the second item further comprises using epipolar geometry within a sequential Monte Carlo implementation.

9. The method of claim 8 wherein using epipolar geometry within a sequential Monte Carlo implementation further comprises substantially avoiding attempting to match first item features with second item features.

10. An apparatus comprising:

a memory having captured temporally parsed data regarding at least a first item, wherein the temporally parsed data comprises data corresponding to substantially simultaneous samples of the at least first item with respect to at least first and a second different points of reference stored therein;

a processor operably coupled to the memory and being configured and arranged to automatically use, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data as corresponds in a given sample to;

the first point of reference; and

the second point of reference;

to disambiguate state information as pertains to the first item.

11. The apparatus of claim 10 wherein the temporally parsed data comprises temporally parsed data that has been captured using at least two cameras that are positioned to have differing views of the first item.

12. The apparatus of claim 10 wherein the processor is further configured and arranged to automatically use, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data by, at least in part, using conditional probabilistic analysis with respect to state information as corresponds to the first item.

13. The apparatus of claim 10 wherein the processor is further configured and arranged to automatically use, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data by, at least in part, determining whether to use a joint conditional probabilistic analysis or a non-joint conditional probabilistic analysis.

14. The apparatus of claim 10 wherein the processor is further configured and arranged to automatically use, at least in part, conditional probabilistic analysis of at least some of the temporally parsed data by determining whether to use the conditional probabilistic analysis for all of the temporally parsed data as corresponds to the given sample.
