It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be practiced in sequences other than those illustrated or described herein.

Referring to fig. 1, fig. 1 is a flowchart of an information encoding method provided in an embodiment of the present application, where the method is applied to an electronic device, and as shown in fig. 1, the method includes the following steps:
step 101: a target feature of the first object is obtained.
In this embodiment, the first object may be selected from a human, an animal (e.g., a wandering animal, a canine, a feline, etc.), and the like. The target feature may comprise a feature in a plurality of dimensions of the first object, i.e. in each of the plurality of dimensions of the first object.
In one embodiment, the first object is taken as an example, and the plurality of dimensions may include at least two of: the time period when the target position is located, the floor when the target position is located, the number of times the target position is passed within a preset time period, the age, the height, the sex and the like. It is understood that, when the first object is an animal other than a human, the corresponding multiple dimensions may include a time period when the first object is at the target position, a number of times the first object passes through the target position within a preset time period, and the like, and may be preset based on actual requirements, which is not limited herein.
Step 102: and respectively determining a target value corresponding to the feature of the first object in each dimension according to a preset mapping relation between the value in the arithmetic progression in each dimension and different features in each dimension to obtain a plurality of target values.
In this embodiment, in order to implement an encoding process, a plurality of dimensions may be preset based on an actual requirement (for example, a feature of an object to be retrieved), then, for each dimension, an arithmetic progression is constructed based on feature content in the dimension, and a mapping relationship between a value in the arithmetic progression and different features is preset, so that a target value corresponding to the feature in the corresponding dimension is determined according to the mapping relationship in the following.
Step 103: and determining the coding information of the target characteristics according to the plurality of target numerical values.
In this embodiment, when the coding information of the target feature is determined according to the plurality of target values, the plurality of target values may be spliced to obtain the coding information of the target feature, or the plurality of target values may be operated based on a preset algorithm (for example, multiplication, weighted averaging, and the like) to obtain the coding information of the target feature, which is not limited herein.
According to the information coding method, the target characteristics of the first object can be obtained, the target characteristics comprise characteristics of the first object under multiple dimensions, the target values corresponding to the characteristics of the first object under each dimension are respectively determined according to the preset mapping relation between the values in the arithmetic progression under each dimension and different characteristics under each dimension, multiple target values are obtained, and the coding information of the target characteristics is determined according to the multiple target values. Therefore, the target characteristics of the encoding object can be encoded by means of the target numerical values under multiple dimensions, so that encoding information is enriched, and the characteristics of the encoding object are effectively reflected.
In the embodiment of the application, the prime number only has two positive factors, namely 1 and the prime number, and is easy to identify and search, so the arithmetic progression is preferentially the arithmetic progression of the prime number, so that the coding information of the coding object is identified and searched, and the coding performance is ensured.
Optionally, in order to reduce the storage space and support the retrieval of partial information, the process of determining the coding information of the target feature in step 103 may include: and determining the product of the plurality of target values as the coding value of the target characteristic. Therefore, in the subsequent retrieval and analysis process, the multidimensional characteristic information of the corresponding object can be obtained by factorization of the coded value.
Optionally, after step 103, the method further includes:
comparing whether the coding information of the target features is consistent with preset retrieval information or not;
under the condition that the coding information of the target feature is consistent with the preset retrieval information, determining that the first object is a target object meeting a preset condition;
or, in the case that the encoded information of the target feature is inconsistent with the preset retrieval information, determining that the first object is not a target object satisfying a preset condition.
Wherein the preset retrieval information can be preset based on actual requirements. Thus, the target object can be retrieved, and the required information can be obtained.
It can be understood that if the encoded information of the target feature is a value obtained by multiplying a plurality of target values, the corresponding preset retrieval information is a preset retrieval value. In this way, the target object can be retrieved by means of a comparison between the two values, thereby improving the retrieval efficiency.
In one embodiment, taking the first object as an example, the corresponding multiple dimensions include a time period when the first object is located in the mall S, an age, a floor when the first object is located in the mall S, and a height.
For dimension 1 (time period when in mall S), the corresponding arithmetic progression is [1,5,9,13,17,21,25,29,33,37,41,45], which means that 24 hours in a day is split into 12 features, each feature represents 2 hours, wherein the corresponding mapping relationship is: "1" corresponds to 0 to 2 points, "5" corresponds to 2 to 4 points, "9" corresponds to 4 to 6 points, … …, and "45" corresponds to 22 to 24 points.
For dimension 2 (age), the corresponding arithmetic progression is [2,6,10,14,18,22,26,30,34,38,42,46], representing a split of ages 0 to 120 into 12 features, each feature representing 10 years, where the corresponding mapping relationship is: "2" corresponds to the ages of 0 to 10, "6" means the ages of 10 to 20, "10" corresponds to the ages of 20 to 30, … …, "46" corresponds to the ages of 110 to 120.
For dimension 3 (the floor where the mall S (including 12 floors, for example)), the corresponding arithmetic progression is [3,7,11,15,19,23,27,31,35,39,43,47], which indicates splitting the floor 12 into 12 features, each feature representing 1 floor, where the corresponding mapping relationship is: "3" corresponds to 1 layer, "7" corresponds to 2 layers, "11" corresponds to 3 layers, … …, "47" corresponds to 12 layers.
For dimension 4 (height), the corresponding arithmetic progression is [4,8,12,16,20,24,28,32,36,40,44,48], which means splitting height 1.4 to 2 meters into 12 features, each feature representing 0.5 meter, wherein the corresponding mapping relationship is: "4" corresponds to 1.40 to 1.45 meters, "8" corresponds to 1.45 to 1.5 meters, … …, "48" corresponds to 1.95 to 2 meters.
Based on the above, the value obtained from dimension 1 × dimension 2 × dimension 3 × dimension 4 can be determined as the arithmetic series encoding result.
Example 1, assume that the target characteristics of user a are: when the user goes to store S at 8 to 9, the age of 25, and goes to the 3 rd floor of store S, the height is 1.64 m, then the target feature of user a corresponds to the code value: 17 × 10 × 11 × 16, i.e., user a corresponds to the code value 29920.
Example 2, assume that the target characteristics of user B are: when going to store S at 8 to 9, age 35, and going to floors 3 and 4 of store S, height 1.71 m, the target feature of user B has the corresponding code value: 17 × 14 × 11 × 15 × 28, i.e., user a corresponds to the code value 1099560.
It should be noted that the above example of the arithmetic progression is only an illustration, and the embodiment of the present application does not limit this, and may continuously adjust and optimize based on actual requirements to ensure the performance of the final coding result. In practice, the difference array such as prime number is preferred.
