US 12,755,543 B2 · Systems and methods for object detection in an environment

Abstract

Disclosed herein are apparatuses and methods for object detection in an environment. An implementation may comprise detecting, using at least one sensor, persons that entered and exited the environment during a first period of time and determining an entry count and an exit count accordingly. The implementation may comprise retrieving, from a database, historical ingress and egress data comprising entry and exit counts of the environment for a second period of time. The implementation may comprise determining an amount of expected exit counts for the first period of time based on the historical ingress and egress data of the second period of time by fitting the historical ingress and egress data to a first probability distribution. The implementation may comprise updating the exit count for the first period of time to the amount of expected exit counts and storing the updated exit count in the database.

Dependent claims

A vision system for detecting objects in an environment, comprising:

at least one sensor;
a memory;
and
a processor communicatively coupled with the memory and the at least one sensor and configured to:
detect, using the at least one sensor, persons that entered and exited the environment during a first period of time;
determine an entry count and an exit count for the first period of time;
retrieve, for a second period of time from a database, historical ingress and egress data comprising historic entry and exit counts of the environment and a missed exit percentage (MEP) indicating a percentage of exits missed in the historic entry and exit counts, wherein the first period of time and the second period of time are at a same time of day across different days;
fit the historical ingress and egress data to a first probability distribution to determine an exit ratio;
update the exit count for the first period of time to an amount of expected exit counts by multiplying the exit ratio with the exit count;
and
store the updated exit count in the database.

A method for use by a vision system for detecting objects in an environment, comprising:

detecting, using at least one sensor, persons that entered and exited the environment during a first period of time;
determining, by a processor, an entry count and an exit count for the first period of time;
retrieving, for a second period of time from a database by the processor, historical ingress and egress data comprising historic entry and exit counts of the environment and a missed exit percentage (MEP) indicating a percentage of exits missed in the historic entry and exit counts, wherein the first period of time and the second period of time are at a same time of day across different days for a second period of time;
fitting, by the processor, the historical ingress and egress data to a first probability distribution to determine an exit ratio;
updating, by the processor, the exit count for the first period of time to an amount of expected exit counts by multiplying the exit ratio with the exit count;
and
storing, by the processor, the updated exit count in the database.

A non-transitory computer-readable medium storing instructions, for use by a vision system for detecting objects in an environment, executable by a processor to perform a method for use by a vision system for detecting objects in an environment, comprising:

detecting, using at least one sensor, persons that entered and exited the environment during a first period of time;
determining an entry count and an exit count for the first period of time;
retrieving, for a second period of time from a database, historical ingress and egress data comprising historic entry and exit counts of the environment and a missed exit percentage (MEP) indicating a percentage of exits missed in the historic entry and exit counts;
fitting the historical ingress and egress data to a first probability distribution to determine an exit ratio;
updating the exit count for the first period of time to an amount of expected exit counts by multiplying the exit ratio with the exit count;
and
storing the updated exit count in the database.
