Image analysis system, image analysis method, and storage medium
First Claim
1. An image analysis system comprising:
- a memory storing instructions;
a central processing unit (CPU) connected to the memory that, based on the instructions, performs operations comprising;
generating an appearance record of an object, the appearance record representing a time when the object appeared in a camera captured image and a location of the object when the object appeared in the camera captured image, the appearance record including appearance time information and location information of the object specified by the camera captured image, wherein generating the appearance record comprises determining that a continuous appearance of the object in one or more camera captured images during a predetermined period constitutes one appearance;
specifying the object as a monitored object when botha time interval is within a predetermined time interval, the time interval being calculated using the time information in the appearance record, andan appearance pattern in the time interval is a predetermined pattern, the appearance pattern being specified based on the location information in the appearance record; and
providing output identifying the monitored object.

Abstract
A monitor target shooting information generation unit extracts, from each of a plurality of images, as information to be used for estimating the identify of a monitor target, monitor target identification information that is identification information of the monitor target, and the monitor target shooting information generation unit then generates multiple pieces of monitor target shooting information each including both the extracted monitor target identification information and a shooting time at which the monitor target was shot. An appearance history generation unit generates, from the generated multiple pieces of monitor target shooting information, an appearance history of the monitor target that has been estimated to be identical. A determination unit determines the monitor target the appearance history of which matches a specified rule.

5. A non-transitory storage medium storing an analysis program including a processor causing a computer to execute:
-
generating an appearance record of an object, the appearance record representing a time that the object appeared in a camera captured image and a location of the object when the object appeared in the camera captured image, the appearance record including appearance time information and location information of the object specified by the camera captured image, wherein generating the appearance record comprises determining that a continuous appearance of the object in one or more camera captured images during a predetermined period constitutes one appearance; specifying the object as a monitored object when both a time interval is within a predetermined time interval, the time interval being calculated using the time information in the appearance record, and an appearance pattern in the time interval is a predetermined pattern, the appearance pattern being specified based on the location information in the appearance record; and providing output identifying the monitored object.
