Image processing apparatus, image processing method, system, and non-transitory computer-readable storage medium

An image processing method performed by an image processing apparatus, the method comprising:

• identifying an object on the basis of a predicted position of the object based on a first frame group in a first frame period, and a position of the object in a target frame;
• identifying an object on the basis of a predicted position of the object based on a second frame group in a second frame period, and a position of the object in the target frame;
• and
• in a case where a plurality of objects are detected in the target frame, executing tracking of a tracking target object on the basis of distances between the plurality of objects, and at least one identification result out of a first identification result of the object based on a detected position of the object and the predicted position of the object based on the first frame group, and a second identification result of the object based on the detected position and the predicted position of the object based on the second frame group, and
• wherein the second frame period is longer than the first frame period.

A non-transitory computer-readable storage medium storing a computer program for causing a computer to function as:

• a first identification unit configured to identify an object on the basis of a predicted position of the object based on a first frame group in a first frame period, and a position of the object in a target frame;
• a second identification unit configured to identify an object on the basis of a predicted position of the object based on a second frame group in a second frame period, and a position of the object in the target frame;
• and
• a control unit configured to, in a case where a plurality of objects are detected in the target frame, execute tracking of a tracking target object on the basis of distances between the plurality of objects, and at least one identification result out of a first identification result of the object based on a detected position of the object and the predicted position of the object based on the first frame group, and a second identification result of the object based on the detected position and the predicted position of the object based on the second frame group, and
• wherein the second frame period is longer than the first frame period.

A system comprising a camera and a control apparatus, the camera comprising:

• an image capturing unit;
• one or more processors;
• and
• one or more memories storing executable instructions which, when executed by the one or more processors, cause the camera to function as a control unit configured to control to track a tracking object and capture an image of the tracking object, and
• the control apparatus comprising:
• one or more processors;
• and
• one or more memories storing executable instructions which, when executed by the one or more processors, cause the image processing apparatus to function as:
• a first identification unit configured to identify an object on the basis of a predicted position of the object based on a first frame group in a first frame period, and a position of the object in a target frame;
• a second identification unit configured to identify an object on the basis of a predicted position of the object based on a second frame group in a second frame period, and a position of the object in the target frame;
• and
• a control unit configured to, in a case where a plurality of objects are detected in the target frame, execute tracking of a tracking target object on the basis of distances between the plurality of objects, and at least one identification result out of a first identification result of the object based on a detected position of the object and the predicted position of the object based on the first frame group, and a second identification result of the object based on the detected position and the predicted position of the object based on the second frame group, and
• wherein the second frame period is longer than the first frame period.
