Claim 11:
12. An object recognition method comprising:
capturing an image of a shooting location where an object is to be placed with a camera; and
recognizing an object included in an image of the shooting location, utilizing a machine learning model for object recognition,
wherein the object recognition method further comprises:
determining necessity of an update operation on the machine learning model for object recognition at a predetermined time;
when the update operation is necessary, causing the camera to capture an image of the shooting location where no object is placed to thereby re-acquire a background image for training; and
causing the machine learning model to be trained using a composite image of a backgroundless object image and the re-acquired background image for training as training data,
wherein the camera captures a current image of the shooting location where no object is placed, to thereby acquire a background image for determination, and
wherein the update operation is determined to be necessary when the background image for determination is different from the background image for training to an amount equal to or greater than a predetermined level.
