Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. An object recognition device comprising:
a camera configured to capture an image of a shooting location where an object is to be placed; and
a processor configured to recognize an object included in an image of the shooting location, utilizing a machine learning model for object recognition;
wherein the machine learning model for object recognition is constructed based on trained model data generated by a training operation using a composite image of a backgroundless object image and a background image for training acquired by capturing an image of the shooting location where no object is placed, and
wherein the processor is configured to:
determine necessity of an update operation on the machine learning model for object recognition at a predetermined time;
when determining that the update operation is necessary, cause 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
cause 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 processor determines that the update operation is 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.
