First Embodiment

The first embodiment of the present invention discloses a self-service method applicable to a shopping mall provided with a plurality of shelves and a plurality of shopping carts. Specifically, each of the shelves is provided with a camera. The shopping carts are respectively pre-provided with different electronic tags. Different electronic tags correspond to different IDs (Identifications). As shown in FIG. 1, the method includes the following steps.

In step 101, video data associated with the shopping cart is acquired, by the camera, the shopping cart being at a distance from the shelf less than a preset value.

Specifically, the camera provided on the shelf is configured to monitor the surroundings around the shelf over a preset range. The specific preset range may be set according to experience, and may be specifically determined according to a distance between a shelf and a spot where a user fetches an article from the shelf under normal circumstances. It can be well determined from the acquired video data whether an article is being transferred between the shelf and the shopping cart.

In step 102, it is determined whether an article is being placed into the shopping cart, based on identification of the video data.

Specifically, each of the pictures contained in the video data is identified to determine a trajectory of the article and the position of the shopping cart, so as to determine whether an article is being placed into the shopping cart.

In step 103, the ID of the shopping cart is acquired, the placed article is determined and the ID is associated with the article, if it is determined that an article is being placed into the shopping cart.

Specifically, if it is determined that an article is being placed into the shopping cart, the ID of the shopping cart is acquired, the placed article is determined and then the ID and the article will be associated with each other.

Specifically, in a specific embodiment, each of the shelves is further provided with an electronic tag reader. The electronic tag reader is configured to acquire the ID contained in the electronic tag of the shopping cart which is away from the shelf at a distance less than a certain value.

The step of acquiring the ID of the shopping cart, determining the placed article and associating the ID with the article includes:

• • acquiring the ID of the shopping cart by the electronic tag reader, and identifying a picture of article captured by the camera so as to determine the placed article.

Specifically, each of the shopping carts is pre-provided with an electronic tag, and each of the shelves is provided with the electronic tag reader which acquires the ID of the shopping cart by reading the electronic tag. To avoid other electronic tags from being read, it is possible to set that only the electronic tag on a shopping cart which is away from the shelf at a distance less than a certain value can be read. Specifically, the distance may be set according to the distance between the shopping cart and a shelf when a user is fetching an article from the shelf under normal circumstances.

An article may be identified based on an article picture that is taken. In an embodiment, for example, pictures of all articles in the shopping mall are captured in advance; specifically, the pictures may be taken from various angles, so as to form a picture library of articles. Subsequently, the article can be determined by matching the picture of article with the pictures in the picture library.

In another specific embodiment, each of the shelves corresponds to a certain type of article within a preset period of time.

The step of identifying a picture of article captured by the camera so as to determine the placed article includes:

• • shooting the article by the camera to capture a picture of article; and
  • performing a first matching procedure, in which the captured picture of article is matched with each of pre-stored pictures of the articles on the shelf, so as to determine an article corresponding to the captured picture of article.

In another embodiment, if the article corresponding to the captured picture of article cannot be determined through the first matching procedure, a second matching procedure is performed, in which the captured picture of article is matched with pre-stored pictures of all articles in the shopping mall, so as to determine the article corresponding to the picture of article.

Specifically, there are numerous pictures of articles of the entire shopping mall, specific articles are stored on certain shelves and normally fetched therefrom, and each of the shelves corresponds to a certain type of article within a certain period of time. Accordingly, in identifying the article, it is preferable to perform a matching procedure, in which the article picture is matched with the pictures of the articles stored on the shelf where the article is located, and only when the previous match fails, a matching procedure in which the article picture is matched with the pictures of all articles in the shopping mall will be performed. In this way, the efficiency is improved.

In step 104, displaying to a user a total sum of all articles associated with the ID when detecting the shopping cart corresponding to the ID is located in a preset payment area of the shopping mall.

Specifically, there are preset payment areas in the shopping mall. The ID of the shopping cart and all articles associated with the ID may be acquired when the shopping cart is in the payment area. The total sum of all articles will be displayed to the user to facilitate the payment. Specifically, the ID may also be acquired by an electronic tag reader provided in the payment area which may read IDs.

In step 105, a permitting procedure for allowing the shopping cart corresponding to the ID to pass is executed, upon reception of a message fed back from the payment area and indicating that the total sum corresponding to the ID has been cleared.

In a specific embodiment, the method further includes:

• • generating a prompt message if the acquisition of the ID of the shopping cart or the determination of the placed article fails; where the prompt message is configured to inform the user to make payment face to face.

In a specific embodiment, it is contemplated that abnormal conditions e.g. power failure may be occur, which makes it impossible to acquire the ID of the shopping cart, or to determine the placed articles. In such cases, the users may be informed to make the payment face to face by a prompt.
