Problems solved by technology

[0002] One of the main functions of the supermarket smart shopping cart is to be able to recognize the customer's hand and whether it has goods in it. The existing skin color detection method is mainly based on the detection method of the face. In order to ensure that the face is detected as much as possible Included in the metering area, the size of the face frame must be increased, so that the data of the background and hair are more or less included in the metering area of ​​the face, because the brightness information of the background varies greatly under different scenes and lighting conditions Large, and combined with the influence of hair and eye color, the metering based on the face is very unstable, which greatly affects the effect of metering

Embodiment 1

[0047] A recognition system based on a supermarket shopping cart hand recognition method, comprising:

[0048] The hand segmentation calculation module, according to the hand movement trend, judges and obtains the picture of the product that the hand may hold;

[0049] Skin color calculation module, it is impossible for the opponent to hold the pictures of the product for skin color segmentation processing;

[0050] Hand-held product judgment module to judge whether the hand really holds the product;

[0051] The statistics module judges whether the user has violated the regulations through the statistics of the results of the hand-held commodity judgment module.

[0052] A supermarket shopping cart hand recognition method, according to the following steps:

[0053] (1) Determine the position of the hand, take the opening of the shopping cart as the reference plane H1, monitor whether there is a target above the reference plane, and save the picture if there is;

Abstract

The invention discloses a supermarket shopping cart hand identification method. The method comprises the following steps of (1) determining a hand position, taking a shopping cart opening as a reference surface H1, monitoring whether an object is located above the reference surface, and storing an image if the object is located above the reference surface; (2) carrying out image processing, and through establishing a skin color model, processing the image acquired from the step1; and (3) determining an object holding state, and carrying out secondary determination on the image acquired from the step2. In the invention, through steps of motion detection, skin color detection and hand and commodity determination, whether a hand holds a commodity can be accurately determined. By using the method, extra burdens and requirements to a user are not generated, and a whole determination process is automatically performed, which is very simple and convenient.

Description

technical field [0001] The invention relates to an image recognition method, in particular to a hand recognition method of a shopping cart in a supermarket.
