Automatic checkout system, method for controlling automatic checkout system and storage medium storing instructions to perform method for controlling automatic checkout system

A method of controlling an automatic checkout system including a storage medium and a processor, the method comprising:

• preparing a product detection model trained based on training images in which a degree of overlap between products is placed within a predetermined cluster ratio range;
• sequentially loading a plurality of frame images according to a predetermined batch size and an asynchronization method and storing the plurality of frame images in an input queue;
• inputting the plurality of frame images sequentially stored in the input queue into the product detection model to detect at least one product according to the predetermined batch size and sequentially storing detection results in a detection queue;
• tracking the detected at least one product by sequentially storing the detection results in the detection queue;
• and
• counting the detected at least one product by sequentially storing tracking results in a counting queue,
• wherein at least two of the loading, the detecting, the tracking, and the counting are performed by independent threads via the input queue, the detection queue, and the counting queue.

A non-transitory computer readable storage medium storing computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a method comprising:

• preparing a product detection model trained based on training images in which a degree of overlap between products is placed within a predetermined cluster ratio range;
• sequentially loading a plurality of frame images according to a predetermined batch size and an asynchronization method and storing the plurality of frame images in an input queue;
• detecting at least one product from each frame images by inputting the plurality of frame images into the product detection model according to the predetermined batch size and sequentially storing detection results in a detection queue;
• tracking the detected at least one product by sequentially storing the detection results in the detection queue;
• and
• counting the detected at least one product by sequentially storing tracking results in a counting queue,
• wherein at least two of the loading, the detecting, the tracking, and the counting are performed by independent threads via the input queue, the detection queue, and the counting queue.
