Assignee: AMAZON TECHNOLOGIES, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 3:
4. A method comprising:
receiving a first plurality of records from a first imaging device having a first field of view, wherein each of the first plurality of records relates to one of a first plurality of images captured by the first imaging device and comprises:
locations of at least one body part depicted in each of the first plurality of images; and
information associating portions of each of the first plurality of images with the locations of the at least one body part;

receiving, from a second imaging device having a second field of view that includes at least a portion of the first inventory area, a second plurality of records, wherein each of the second plurality of records relates to one of a second plurality of images captured by the second imaging device and comprises:
locations of at least one body part depicted in each of the second plurality of images; and
information associating portions of each of the second plurality of images with the locations of the at least one body part;

receiving, from at least one sensor, an indication that an event has occurred at an event location for a duration;
determining that the event location is within the first field of view and the second field of view during at least a portion of the duration; and
in response to determining that the event location is within the first field of view and the second field of view during at least the portion of the duration,
determining a first regression vector based at least in part on at least a first record of the first plurality of records, wherein the first regression vector extends from a first portion of a first image of the first plurality of images corresponding to a first body part of a first actor and a second portion of the first image corresponding to the event location;
determining a second regression vector based at least in part on at least a second record of the second plurality of records, wherein the second regression vector extends from a first portion of a second image of the second plurality of images corresponding to the first body part and a second portion of the second image corresponding to the event location;
determining a first confidence score that the first actor is associated with the event based at least in part on the first regression vector;
determining a second confidence score that the first actor is associated with the event based at least in part on the second regression vector;
determining a first factor based at least in part on a first subset of the first plurality of records;
determining a second factor based at least in part on a second subset of the second plurality of records; and
determining that the first actor is associated with the event based at least in part on the first confidence score and the first factor.
