obtaining the identification information and the appearance attribute of the article for each article that is about to enter the article conveying queue; and

associating the obtained appearance attribute with the identification information of the corresponding article;

the step of identifying an appearance attribute of the article through the monitoring camera to determine the identification information of the article comprises:

identifying the appearance attribute of the article through the monitoring camera; and

determining the identification information of the article according to the identified appearance attribute and an incidence relation between the appearance attribute and the identification information.

3 . The article positioning method according to claim 1 , wherein the method further comprises:

identifying the appearance attributes of the articles in sequence through sequence maintenance cameras in a conveying process of the articles in the conveying queue;

comparing the identified appearance attributes with the appearance attributes of the corresponding articles in the article sequence in sequence to determine whether the current conveying sequence is consistent with the article sequence; and

if the current conveying sequence is inconsistent with the article sequence, updating the article sequence according to the current conveying sequence.

4 . The article positioning method according to claim 3 , wherein the sequence maintenance cameras are distributed at corners of an article conveying area.

5 . The article positioning method according to claim 2 , wherein the appearance attribute comprises at least one of a category attribute, a color attribute, a size attribute, a shape attribute and a material attribute, and the step of identifying an appearance attribute of the article through a monitoring camera to determine the identification information of the article comprises:

respectively identifying the article under each appearance attribute dimension through the monitoring camera, and determining a confidence coefficient of the identification result; and

performing a similarity comparison on the identification result and the confidence coefficient under each appearance attribute dimension with the appearance attributes in the incidence relation to determine the identification information of the article.

6 . The article positioning method according to claim 1 , wherein the conveying queue comprises a target article to be positioned, and the step of positioning the target article through the appearance attribute of each article and the article sequence comprises:

comparing the appearance attributes of the target article, at least one article located in front of the target article and at least one article located behind the target article with the appearance attributes corresponding to the article sequence to determine the identification information and the current location of the target article.

7 . The article positioning method according to claim 1 , wherein the step of when each article enters the conveying queue, identifying the appearance attribute of the article through the monitoring camera to determine the identification information of the article comprises:

identifying the appearance attribute of the article through the monitoring camera when each article enters the conveying queue; and

determining the identification information of the article according to the appearance attribute of the article and the sequence of the article entering the article positioning system.

8 . An article positioning system, comprising:

at least one camera, configured to identify an appearance attribute of an article; and

a processor, connected with the at least one camera and configured to: when each article enters a conveying queue, identifying the appearance attribute of the article through the at least one camera to determine identification information of the article; determine an article sequence of the conveying queue after the article is added according to a location of the article entering the conveying queue and the identification information of the article; and position the article in the conveying queue through the appearance attribute of each article and the article sequence.

9 . The article positioning system according to claim 8 , wherein the processor is further configured to:

obtain the identification information and the appearance attribute of the article for each article that is about to enter the article conveying queue;

associate the obtained appearance attribute with the identification information of the corresponding article;

identify the appearance attribute of the article through the at least one camera; and

determine the identification information of the article according to the identified appearance attribute and an incidence relation between the appearance attribute and the identification information.

10 . The article positioning system according to claim 8 , wherein the at least one camera comprises sequence maintenance cameras, and the processor is further configured to:

identify the appearance attributes of the articles in sequence through the sequence maintenance cameras in a conveying process of the articles in the conveying queue;

compare the identified appearance attributes with the appearance attributes of the corresponding articles in the article sequence in sequence to determine whether the current conveying sequence is consistent with the article sequence; and

if the current conveying sequence is inconsistent with the article sequence, update the article sequence according to the current conveying sequence.

11 . The article positioning system according to claim 10 , wherein the sequence maintenance cameras are distributed at corners of an article conveying area.

12 . The article positioning system according to claim 9 , wherein the appearance attribute comprises at least one of a category attribute, a color attribute, a size attribute, a shape attribute and a material attribute, and the processor is configured to:

respectively identify the article under each appearance attribute dimension through the at least one camera, and determine a confidence coefficient of the identification result; and

perform a similarity comparison on the identification result and the confidence coefficient under each appearance attribute dimension with the appearance attributes in the incidence relation to determine the identification information of the article.

13 . The article positioning system according to claim 8 , wherein the conveying queue comprises a target article to be positioned, and the processor is configured to:

compare the appearance attributes obtained by the at least one camera of the target article, at least one article located in front of the target article and at least one article located behind the target article with the appearance attributes corresponding to the article sequence to determine the identification information and the current location of the target article.

14 . The article positioning system according to claim 8 , wherein the processor is configured to:

identify the appearance attribute of the article through the at least one camera when each article enters the conveying queue; and

obtain the identification information of the article according to the appearance attribute of the article and the sequence of the article entering the article positioning system.

15 . A computer program product, wherein the computer program product comprises a computer program executable by a programmable apparatus, and the computer program has a code part for executing the method in claim 1 when being executed by the programmable apparatus.
