[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a self-service shopping system 10 according to a first embodiment of the present invention includes a shopping cart 11, a weighing module 12, a code scanning module 13, a communication module 14, a camera module 15, and a server 16. The shopping cart 11 is used for loading commodities, the weighing module 12 is used for weighing the weight of the commodities in the shopping cart 11, and the code scanning module 13 is used for scanning two-dimensional codes on the commodities to acquire commodity information. The camera module 15 is used for shooting the motion video after the code scanning of the commodity, and the communication module 14 is used for transmitting the commodity information, the weight information in the shopping cart 11, the weight information on the supermarket shelf and the video shot by the camera module 15 to the server 16. The server 16 is used for comparing whether the change of the weight information in the shopping cart 11 is consistent with the change of the weight information on the shelf of the supermarket, analyzing the motion track of the commodities in the video and counting the total price of the commodities in the shopping cart 11.
Specifically, camera module 15 includes a plurality of cameras, and a plurality of cameras shoot the motion trail of commodity after sweeping the sign indicating number simultaneously to avoid increasing the shooting scope, avoid shooing the dead angle. The weight and video information of the change obtained by the weighing module 12 and the camera module 15 are transmitted to the server 16 through the communication module 14 for analysis, comparison and statistics.
It can be understood that a plurality of cameras of the camera module 15 can be arranged on the shopping cart or independently arranged, so long as the camera module can move along with the shopping cart and can shoot video information which is lost into the shopping cart after a commodity is scanned by a user.
It can be understood that the commodities are packaged individually, that is, each commodity is an individual and cannot be disassembled any more. In some embodiments, the merchandise may also be a merchandise that is enclosed by a bag from bulk items and has a merchandise code.
It can be understood that the commodity code can be a two-dimensional code, a bar code and the like, and the commodity information can be acquired after the code is scanned by the electronic equipment.
It is understood that the commodity information includes commodity appearance characteristics, commodity unit weight and commodity unit price.
Further, the self-service shopping system 10 further includes a display module 17, the display module 17 is a touch display device, and is disposed on the shopping cart 11 for displaying the commodity information in the shopping cart, and when the user needs to return the commodity in the shopping cart 11, the operation can be performed through the display module. Meanwhile, after the server 16 counts the total price of the commodities in the shopping cart, the display module 17 can display the two-dimensional code, so that a user can conveniently scan the code to pay.
Referring to fig. 2, a second embodiment of the present invention provides a self-service shopping method for accurately calculating the total price of the commodities in the shopping cart through the autonomous shopping system 10, which includes the following steps:
s1: removing the goods from the shelves;
s2: scanning the code of the commodity, acquiring the commodity information of each code-scanned commodity, and recording all the code-scanned commodities; and
s3: and acquiring a video of the commodities after code scanning, setting a shopping cart area in the video, and capturing the motion track of the commodities in the video to judge whether the commodities are put into the shopping cart.
When a user purchases in a supermarket, the user takes goods off a shelf of the supermarket, then performs code scanning operation on the goods, then puts the goods into a shopping cart, and after the purchase is finished, pays according to the total price of the goods in the shopping cart, so that the shopping operation can be finished.
In some application scenarios, a user may lose the desire to purchase the goods after scanning the codes and then drop the goods onto a shelf at will, or replace the goods after scanning the codes and place the goods without scanning the codes into a shopping cart, and these erroneous operations may affect the subsequent progress of shopping and increase the management cost of the supermarket.
In order to avoid the situation that the total price does not correspond to the time product in the shopping cart during payment, further control needs to be performed on the behavior of the user during autonomous shopping.
Specifically, the commodity information on the shelf is pre-stored in the database in advance, and when the user takes off the commodity to be purchased from the shelf, the specific numerical value of the commodity unit weight can be obtained. Then, the user scans the goods taken off the shelf to obtain the goods information of the goods, namely the appearance characteristics of the goods, the single weight information of the goods and the unit price of the goods. At this time, the motion track of the goods after code scanning is obtained, namely the motion route of the goods in the process of where the user puts the goods after code scanning. When the display commodity is put into the shopping cart, the weight of the display commodity is changed after the commodity is put into the shopping cart, if the weight change in the shopping cart is consistent with the single weight of the commodity taken away from the goods shelf, the display commodity is the same as the commodity taken away from the goods shelf, and a user can finish shopping only by paying for the total price generated according to the commodity information in the shopping cart after the shopping is finished. When the display commodity is not placed in the shopping cart, for example, the user randomly puts the code-scanned commodity back to a shelf or replaces the code-scanned commodity with other commodities, the shopping cart gives an abnormal alarm to remind the user of illegal operation.
Referring to fig. 3, the step S2 includes a step S21: scanning the goods and acquiring the goods information; and
in step S22, the unit prices of the goods passing the code scanning are accumulated.
Specifically, after the goods are taken off from the shelf and before the goods are put into the shopping cart, the goods need to be scanned to obtain the goods information of the goods, that is, the appearance characteristics, the single weight information and the unit price of the goods. In order to facilitate subsequent payment operation, the unit prices of the commodities are accumulated every time the user scans the codes, so that the total price of the commodities in the shopping cart is formed.
In some application scenarios, after scanning the code of the commodity and placing the commodity in the shopping cart, the user loses the desire to purchase the commodity, and needs to take out the commodity in the shopping cart, scan the code again, and then place the commodity back to the shelf or to a designated position. In this case, the unit price of the commodity obtained by scanning the code is a negative number, and the accumulated result is the total price minus the price of the commodity taken out, so as to ensure that the commodity in the final shopping cart is matched with the actually generated total price.
That is, when the user scans the product obtained from the outside of the shopping cart, the product unit price is a positive number, and when the user takes the product from the inside of the shopping cart, the code is scanned, the product unit price is a negative number.
It can be understood that whether the user takes out the goods from the shopping cart for code scanning can be determined by whether the total weight in the shopping cart is reduced. If the total weight of the commodities in the shopping cart is detected to be reduced and the user conducts code scanning operation on the commodities, the commodities are judged to be taken out from the shopping cart, and the unit price of the commodities obtained through code scanning is negative.
It can be understood that the total price of the items in the shopping cart is not limited to the accumulation of each code scanning, as long as the total price of the items in the shopping cart can be obtained finally.
Referring to fig. 4, the step S3 includes a step S31: converting the acquired video into pictures by taking each frame as a unit;
step S32, establishing a coordinate system on each picture by taking the same position of each picture as an origin;
step S33, establishing a shopping cart area in a coordinate system; and
and step S34, recognizing the position of the commodity in the coordinate system in each picture, judging that the commodity is put into the shopping cart when the position of the commodity in the picture is in the shopping cart area, judging that the operation of the user is illegal when the position of the commodity cannot be found in the coordinate system, and alarming by the shopping cart.
The specific position selected as the origin is not limited, and can be adjusted based on the state of the actual shopping cart. It should be particularly noted that the specific steps S31-S34 of the above step S3 are only examples of the present invention and are not intended to limit the present invention.
After the user takes the goods from the shelf and scans the codes, in order to prevent the user from not putting the goods into the shopping cart or putting the code-scanned goods into the shopping cart instead of other goods, the code-scanned goods need to be monitored, that is, the movement track of the goods needs to be monitored.
In some application scenarios, a user takes a commodity a with a unit price of 10 yuan, scans the code of the commodity a, puts the commodity a back after scanning the code, and takes a commodity B with a unit price of 20 yuan to put the commodity B into a shopping cart, wherein if the weight difference between the commodity a and the commodity B is small, the situation that the commodity a is bought at the price of 10 yuan may occur, and a loss may be caused to a shopping mall.
In order to avoid this situation, it is necessary to ensure that the scanned goods are not replaced by other goods. The specific implementation method comprises the steps of acquiring a video of a commodity after code scanning, capturing position change of the commodity in the video, and analyzing whether the code-scanned commodity is placed in a shopping cart or not through the position change. When the goods after code scanning are actually put into the shopping cart, the next operation can be normally carried out, and when the goods after code scanning are not put into the shopping cart and are out of the range of the video, the situation that goods replacement or other situations possibly occur is indicated, and at the moment, the shopping cart sends out an alarm to remind a user of abnormal operation.
It should be noted that, in the above steps, the interval time of each frame of picture can be selected as required to meet the requirements of different application scenarios, so that the monitoring accuracy can be ensured while the calculation amount is reduced as much as possible.
Specifically, after the acquired video is obtained, the video is converted into a picture form in a frame unit, and a coordinate system is established with the same position of each picture as an origin, for example, all the pictures are established with one corner as the origin. And then establishing a corresponding shopping cart area in the coordinate system, wherein the position of the shopping cart area in the coordinate system in each picture is the same as the position of the original point in each picture, and the commodity information obtained during code scanning comprises the appearance characteristics of the commodity, and the appearance characteristics serve as the judgment basis of the position of the commodity in the coordinate system, so that the position of the commodity in the coordinate system in each picture can be obtained. If the position of the commodity cannot be captured in any picture, namely the corresponding commodity is considered to be lost in the coordinate system, the commodity is out of the range of acquiring the video, and illegal operation may exist. When the captured commodities are not lost in the coordinate system in all the pictures corresponding to the videos, and the positions where the commodities are captured in the pictures are located in the shopping cart area, the commodities are judged to be placed in the shopping cart.
It can be understood that when a plurality of cameras with different angles are used for video shooting, pictures formed by the videos shot by each camera are separately judged, namely, the shopping cart areas are the same in the coordinate system set by the pictures formed by the videos shot by each camera.
For example, the motion track of the commodity is shot by using three cameras, namely a camera A, a camera B and a camera C, the shot video is divided into three videos, namely a video A, a video B and a video C, and then a coordinate system is respectively established by using pictures formed by the three videos so as to judge whether the commodity is put into a shopping cart or not.
Referring to fig. 5A-5B, the self-service shopping method further includes step S4: after the commodity is placed in the shopping cart, acquiring the weight change in the shopping cart, and judging whether the weight change in the shopping cart is consistent with the single weight of the placed commodity; and
step S5: and after the weight change is judged to be consistent, calculating the total commodity price in the shopping cart according to the commodity information of the code-scanned commodity.
Specifically, after the user operates normally as verified in step S3, a weight verification is added, that is, the weight of the scanned code item is compared with the actual changed weight of the shopping cart, and then the total price in the shopping cart is calculated, so that the calculated total price is more accurate.
Specifically, the step S4 further includes a step S41: acquiring the total weight of commodities in a shopping cart;
step S42: subtracting the weight in the shopping cart before code scanning from the total weight obtained in the step S41 to obtain the change of the weight of the commodity; and
step S43: and comparing the obtained weight change of the commodity with the commodity taken away from the goods shelf to judge whether the weight change of the commodity is consistent with the weight change of the commodity taken away from the goods shelf.
Specifically, after the commodity is placed in the shopping cart after the code is scanned, the total weight of the commodity in the shopping cart is obtained, and then the weight of the commodity in the shopping cart before the code is scanned is subtracted from the total weight, so that the weight change of the commodity in the shopping cart, that is, the weight of the commodity placed in the shopping cart can be obtained. The weight is compared with the single weight of the commodity taken out of the shelf obtained in step S1, and if the result of the comparison is identical, it is determined that the commodity taken out of the shelf is identical to the commodity put in the shopping cart. Otherwise, the operation is judged to be abnormal, and the shopping cart gives an alarm.
By obtaining the comparison between the movement track of the commodities after code scanning and the weight of the goods shelf and the weight of the shopping cart, the final total price of the commodities in the shopping cart can be accurately obtained.
Referring to fig. 6, the self-service shopping method further includes step S6 of providing a payment code so that the user can pay for the goods in the shopping cart by scanning the payment code.
Specifically, after the total price of the commodities in the shopping cart is generated, the payment code is generated, and the user can scan the code payment code to pay for the commodities in the shopping cart.
It can be understood that the payment code generation can be that a display screen is arranged on the shopping cart to generate the payment code according to the summary, or that a two-dimensional code for payment is pasted on the shopping cart, and the user inputs the amount of money by himself after scanning the code.
