Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.

FIG. 1 is a schematic diagram of an intelligent sales counter according to an embodiment of the present invention.

As shown in fig. 1, an intelligent sales counter according to an embodiment of the present invention includes a cabinet 101, an article rack 102, a camera 103, a gravity sensor 104, a processing module, and an alarm device 105; wherein:

an article rack 102 is installed in the cabinet 101 for placing a first article;

a photographing device 103 for photographing a first image of a first article placed on the article rack 102 and a second image of a moving object;

a gravity sensor 104 is mounted at the bottom of the article rack 102 for detecting a first weight of the first article; detecting a second weight of a second item when the second item is placed on the item holder 102;

the processing module is used for determining whether foreign matters are placed in the intelligent sales counter or not according to the first image and the second image when the difference value between the first weight and the second weight is smaller than a preset first threshold value; when the foreign matter is determined to be placed in the intelligent sales counter, the alarm device 105 is triggered;

and the alarm device 105 is used for responding to the triggering of the processing module and sending alarm information.

In the embodiment of the present invention, the shooting device 103 may include a first camera, and the first camera is disposed inside the cabinet 101; when a second article is put into the cabinet 101, an image of the moving second article is taken as a second image.

For example, as shown in fig. 2 and fig. 3a, in fig. 2, the first weight detected by the gravity sensor 104 is the weight of the first article on the right side (i.e. the cylinder on the right side in fig. 2), specifically, the first weight is determined by: the gravity sensor 104 detects a third weight of the article rack 102 when the first article is placed in the article rack 102 and a fourth weight of the article rack 102 after the first article is picked up from the article rack 102; the first weight is then determined by the processing module based on the third weight and the fourth weight. Next, as shown in fig. 3a, the first article is taken out, and a second article (i.e. the shaded square in fig. 3 a) is placed on the article rack 102, at this time, the processing module first determines whether a difference between the first weight and the second weight of the second article is smaller than a preset first threshold, and if not, determines that a foreign object is placed in the intelligent sales container; if so, then it is determined whether a foreign object is placed in the intelligent sales counter based on the first image and the second image, obviously the cube in fig. 3a is different from the cylinder in fig. 2, so the processing module determines that a foreign object is placed in the intelligent sales counter at this time and triggers the alarm device 105.

In the embodiment of the present invention, the first camera disposed inside the cabinet 101 may be tilted outward, and has a certain tilt angle, which is related to the size of the cabinet, so that the first camera can shoot an environmental image in a certain area outside the cabinet. In a preferred embodiment of the invention, the angle of inclination is 23 degrees.

In the embodiment of the present invention, the first camera may be disposed on one side of the inside of the cabinet 101 as shown in fig. 3a, may also be disposed in a crossing manner on two sides of the inside of the cabinet 101 as shown in fig. 3b, and may also be disposed inside the cabinet 101 in other manners, which is not limited to this scheme.

In the embodiment of the present invention, the shooting device 103 includes a second camera, and the second camera is disposed outside the cabinet 101; the second camera is used for shooting an environment image containing a moving object outside the cabinet body 101 and transmitting the environment image to the processing module; and the processing module is used for determining whether foreign matters are placed in the intelligent sales counter or not according to the environment image and the first image.

In the embodiment of the present invention, the second camera disposed outside the cabinet 101 may also be used to monitor the environment around the cabinet, and when the alarm device 105 sends out alarm information, the situation can be traced back through the monitoring record of the second camera.

In an embodiment of the present invention, the processing module is configured to determine whether a first item is included in the moving object in the environment image, and if so, determine that a foreign object is placed in the smart sales counter.

For example, as shown in fig. 2 and 4, in fig. 2, the first weight detected by the gravity sensor 104 is the weight of the first item on the right side (i.e., the cylinder on the right side in fig. 2). Next, as shown in fig. 4, the first article is taken out, and a second article (i.e. a cylinder with a shadow in fig. 4) is placed on the article rack 102, at this time, the processing module first determines whether a difference between the first weight and the second weight of the second article is smaller than a preset first threshold, and if not, determines that a foreign object is placed in the intelligent sales container; if so, it is determined again whether the first item is included in the moving object in the environment image, as can be seen from fig. 4, the first item is included in the moving object (i.e., the black hand) in the environment image, so the processing module determines that a foreign object is placed in the smart sales counter at this time, and triggers the alarm device 105.

In an embodiment of the present invention, the processing module may determine whether the first item is included in the moving object in the environment image by using an edge algorithm.

In an embodiment of the invention, the alarm device 105 may be a display screen comprising a speaker, in which case the image of the environment determined by the processing module may be displayed on the display screen. And after receiving the trigger of the processing module, the alarm information containing sound and characters can be sent out through the loudspeaker and the display screen.

In an embodiment of the present invention, the display screen may be further configured to display a door opening two-dimensional code, a payment two-dimensional code, and a list of first items taken out by the user.

In the embodiment of the invention, when the user uses the intelligent terminal to scan the door-opening two-dimensional code to open the cabinet door, a shopping page can be displayed on the intelligent terminal, and when the user takes out one or more first articles, a list of the first articles taken out by the user is displayed on the shopping page.

In the embodiment of the invention, when the processing module determines that the second article put in the intelligent sales counter is not the foreign matter, the second article is a certain first article taken out before, so that the corresponding first article can be deleted from the list of the first articles displayed on the display screen and/or the list of the first articles displayed on the user intelligent terminal according to the recognition result of the put-back second article.

In an embodiment of the present invention, the processing module is configured to determine whether a similarity between the first image and the second image is greater than a preset second threshold, and if so, determine that the moving object in the environment image is the first item.

In an embodiment of the present invention, the processing module is configured to determine that a foreign object is placed in the intelligent sales counter when it is determined that the difference between the first weight and the second weight is not less than the first threshold.

In an embodiment of the present invention, the gravity sensor 104 is configured to detect a third weight of the article rack 102 when the first article is placed on the article rack 102 and a fourth weight of the article rack 102 after the first article is picked up from the article rack 102; a processing module for determining a first weight from the third weight and the fourth weight.

In an embodiment of the present invention, the processing module is configured to determine that a foreign object is placed in the intelligent sales counter when it is determined that a difference between the second weight and the third weight is greater than a preset third threshold.

In a preferred embodiment of the present invention, the preset third threshold is 0. For example, as shown in fig. 2 and 5, in fig. 2, the third weight detected by the gravity sensor 104 is the weight of two first articles in the figure (i.e. two cylinders in fig. 2), and in case that no first article is taken out, as shown in fig. 5, the gravity sensor 104 detects the second weight of a second article (i.e. a shaded square in fig. 5), so the processing module determines that a foreign object is put into the intelligent sales counter at this time and triggers the alarm device 105.

In the embodiment of the invention, the intelligent sales counter can further comprise an electronic lock, the electronic lock comprises an electromagnetic generator and an iron block, and the electromagnetic generator and the iron block are respectively arranged on the cabinet body and the cabinet door and are used for controlling the opening and closing of the cabinet door.

In the embodiment of the invention, the intelligent sales counter can further comprise a compressor for refrigerating the intelligent sales counter.

According to the intelligent sales counter disclosed by the embodiment of the invention, whether foreign matters are placed in the intelligent sales counter can be determined through the information acquired by the shooting device and the gravity sensor, and when the foreign matters are determined to be placed in the intelligent sales counter, the alarm device can be triggered to send alarm information, so that the intelligent sales counter can detect the foreign matters and send the alarm information, further, other articles in the intelligent sales counter are prevented from being damaged, and the normal use experience of a user is ensured.
