The keeper's note
Detects free-standing groups of individuals by grouping people who share a transactional segment, for crowd/queue-aware guest sensing (granted).
Abstract
There is provided a system and method for grouping a plurality of individuals, each individual of the plurality of individuals having a corresponding transactional segment, the system comprising a memory storing a group identification application, aprocessor for executing the group identification application to identify an o-space center of a first group, wherein the o-space center is an intersection of a plurality of transactional segments, obtain a non-parametric lower-body orientation probability distribution for each of the plurality of individuals, based on the o-space center, and determine that a first plurality of individuals from the plurality of individuals belong to the first group based on the non-parametric lower-body orientation probability distribution of each individual of the plurality of individuals, wherein each of the first plurality of individuals has a corresponding one of the plurality of transactional segments that intersect with one another.

Claims
1. A system for grouping a plurality of individuals, each individual of the plurality of individuals having a corresponding transactional segment, the systemcomprising: a memory storing a group identification executable code; a camera configured to obtain images of the plurality of individuals; at least one of a display and a speaker configured to communicate with the plurality of individuals; and a processor for executingthe group identification executable code to: identify, using the images, an o-space center of a first group, wherein the o-space center is an intersection of a plurality of transactional segments; obtain a non-parametric lower-body orientation probability distribution for each of the plurality of individuals, based on the o-space center; determine that a first plurality of individuals from the plurality of individuals belong to the first group based on the non-parametric lower-body orientation probability distribution of each individual of the plurality of individuals, wherein each of the first plurality of individuals has a corresponding one of the plurality of transactional segments that intersect with one another; track the non-parametric lower-body orientation probability distribution for a first individual of the determined first plurality of individuals based on at least one of a position of the first individual of the plurality of individuals in the area, a velocity of the first individual of the plurality of individuals in the area, and a head orientationof the first individual of the plurality of individuals in the area; move the o-space more when the first individual moves backwards or forwards than when the first individual moves sideways; and communicate, using the at least one of the display and the speaker, with one or more of the determined first plurality of individuals.
7. A method of identifying free-standing conversational groups among a plurality of individuals in an area, using a system having a memory, at least one of a display and a speaker, a camera and a processor, the method comprising: obtaining, by the camera, images of the plurality of individuals; identifying, by the processor using the images, an o-space center of a first group, wherein the o-space center is an intersection of a plurality of transactional segments; obtaining,by the processor, a non-parametric lower-body orientation probability distribution for each of the plurality of individuals, based on the o-space center; determining, by the processor, that a first plurality of individuals from the plurality of individuals belong to the first group based on the non-parametric lower-body orientation probability distribution of each individual of the plurality of individuals, wherein each of the first plurality ofindividuals has a corresponding one of the plurality of transactional segments that intersect with one another; tracking, by the processor, the non-parametric lower-body orientation probability distribution for a first individual of the determined first plurality of individuals based on at least one of a position of the first individual of the plurality of individuals in the area, a velocity of the first individual of the plurality of individuals in the area, and a head orientation of the first individual of the plurality of individuals in the area; moving, by the processor, the o-space more when the first individual moves backwards or forwards than when the first individual moves sideways; and communicating, by the processor using the at least one of the display and the speaker, with one or more of the determined first plurality of individuals.
12. A robot for interacting with a plurality of individuals, the robot comprising: a memory storing a group identification executable code; a camera configured to obtain images of the plurality of individuals; at least one of a display and a speaker configured to communicate with the plurality of individuals; and a processor for executing the group identification executable code to: identify, usingthe images, an o-space center of a first group of the plurality of individuals each having a corresponding transactional segment, wherein the o-space center is an intersection of a plurality of transactional segments; obtain a non-parametric lower-body orientation probability distribution for each of the plurality of individuals, based on the o-space center; determine that a first plurality of individuals from the plurality of individuals belongto the first group based on the non-parametric lower-body orientation probability distribution of each individual of the plurality of individuals, wherein each of the first plurality of individuals has a corresponding one of the plurality of transactional segments thatintersect with one another; track the non-parametric lower-body orientation probability distribution for a first individual of the determined first plurality of individuals based on at least one of a position of the first individual of the plurality of individuals in the area, a velocity of the first individual of the plurality of individuals in the area, and a head orientation of the first individual of the plurality of individuals in the area;move the o-space more when the first individual moves backwards or forwards than when thefirst individual moves sideways; and communicate, using the at least one of the display and the speaker, with to one or more of the determined first plurality of individuals.
