Parking lot management system, parking lot management method, and recording medium
A parking lot management system according to an aspect of the present disclosure includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: determine, based on a predetermined condition, whether a person who has been detected from an image in which a parking lot is imaged is a parking lot user who has come in by vehicle; determine, based on an appearance of the person who has been determined to be the parking lot user, and an appearance of a person who has been detected from an image in which a store area is imaged, whether the parking lot user was detected in the store area; and output information about the parking lot user based on a result of the determination regarding whether the parking lot user was detected in the store area.
1 . A parking lot management system comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
determine, based on a predetermined condition, whether a person who has been detected from an image in which a parking lot is imaged is a parking lot user who has come in by vehicle;
determine, based on a matching degree between an appearance of the person who has been determined to be the parking lot user, and an appearance of a person who has been detected from an image in which a store area is imaged, that the parking lot user was detected in the store area when the matching degree exceeds a threshold;
lower the threshold for the matching degree for a predetermined time after the parking lot user is no longer detected in the parking lot; and
output information about the parking lot user based on a result of the determination regarding whether the parking lot user was detected in the store area.
2 . The parking lot management system according to claim 1 , wherein
the information about the parking lot user is information indicating that a parking lot user not detected in the store area is present.
3 . The parking lot management system according to claim 2 , wherein
the information about the parking lot user is information for identifying the parking lot user not detected in the store area.
4 . The parking lot management system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
output information indicating that the person detected in the store area is a parking lot user as the information about the parking lot user to a store clerk.
5 . The parking lot management system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
determine whether the parking lot user who was no longer detected in the parking lot was detected in a store area.
6 . The parking lot management system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
in a case where a vehicle is detected within a predetermined range from a position where the person is detected in the parking lot, determine that the person is a parking lot user.
7 . The parking lot management system according to claim 6 , wherein the at least one processor is further configured to execute the instructions to:
in a case where the vehicle is detected from an image in which the parking lot is imagined within a predetermined time from a time when the person is detected in the parking lot, determine that the person is a parking lot user.
8 . The parking lot management system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
determine that a vehicle on which the parking lot user has ridden is parked, and
in a case where the vehicle is parked, determine whether the parking lot user was detected in the store area.
9 . The parking lot management system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
determine whether the person outside the vehicle is a parking lot user.
10 . The parking lot management system according to claim 9 , wherein the at least one processor is further configured to execute the instructions to:
determine whether the person outside the vehicle is a parking lot user based on a position first detected in the parking lot.
11 . The parking lot management system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
determine, based on a walking direction of the person in the parking lot, whether the person is a parking lot user who has come in by vehicle.
12 . A parking lot management method comprising:
determining, based on a predetermined condition, whether a person who has been detected from an image in which a parking lot is imaged is a parking lot user who has come in by vehicle;
determining, based on a matching degree between an appearance of the person who has been determined to be the parking lot user, and an appearance of a person who has been detected from an image in which a store area is imaged, that the parking lot user was detected in the store area when the matching degree exceeds a threshold;
lowering the threshold for the matching degree for a predetermined time after the parking lot user is no longer detected in the parking lot; and
outputting information about the parking lot user based on a result of the determination regarding whether the parking lot user was detected in the store area.
13 . A non-transitory recording medium that records a program for causing a computer to execute the steps of:
determining, based on a predetermined condition, whether a person who has been detected from an image in which a parking lot is imaged is a parking lot user who has come in by vehicle;
determining, based on a matching degree between an appearance of the person who has been determined to be the parking lot user, and an appearance of a person who has been detected from an image in which a store area is imaged, that the parking lot user was detected in the store area when the matching degree exceeds a threshold;
lowering the threshold for the matching degree for a predetermined time after the parking lot user is no longer detected in the parking lot; and
outputting information about the parking lot user based on a result of the determination regarding whether the parking lot user was detected in the store area.
14 . The parking lot management system according to claim 1 , wherein
the parking lot and the store area have different lighting conditions.
15 . The parking lot management system according to claim 14 , wherein
the parking lot is located outdoors, and the store area is located inside a building.
