[0035] It should also be further understood that the term "and/or" used in the description of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations .
[0036] Please refer to the attached figure 1 , with figure 1 It is a flow chart of a method for selecting a commercial location provided by an embodiment of the present invention, and the method for selecting a commercial location includes the following steps:
[0037] Step S101, the computer receives a circled area on the city map input by the user, and the circled area is a reference area for site selection.
[0038] For example: the urban grid similarity algorithm based on digital image recognition technology, relying on the big data platform, images the data with grid attributes, and accurately and efficiently calculates the similarity relationship between grids through image recognition technology. The application scenario of the embodiment of the present invention is that the user circles a plot in the Beijing Guomao area on the electronic map of the computer terminal, and the purpose is to find several other similar plots in the Beijing area for commercial activities. The specified area is the reference area.
[0039] Step S102. Divide the above-mentioned city into several grids, and ensure that the circled area falls into a certain grid.
[0040] In this embodiment, the mature geohash algorithm needs to be used for urban gridding. Divide the entire Beijing map into several grids of standard size. The plots circled by the user can fall into one of the grids, and then other similar grids are recommended to the user through the algorithm of the present invention. Geohash is a mature address encoding method, which can encode two-dimensional spatial longitude and latitude data into a string. The basic principle is to understand the earth as a two-dimensional plane, recursively decompose the plane into smaller sub-blocks, each sub-block has the same code within a certain range of latitude and longitude, this method is simple and easy to use, and can meet the needs of small-scale The data is retrieved by latitude and longitude. It can be found that when the six-digit geohash is used for grid division, the plot circled by the user just falls in the grid with ID WX4g41. Therefore, the entire Beijing map is divided into grids by six-digit geohash, and the size of the six-digit geohash grid is about 1.2Km*0.6Km.
[0041] Step S103 , extract big data of the portrait within a set time, use the big data to make a grid portrait of each grid, and obtain the label value of the grid label of the grid portrait.
[0042] Among them, see figure 2 , figure 2 It is a sub-flow chart of the embodiment of the present invention, the step S103 of extracting the big data of the portrait within the set time, using the big data to make a grid portrait of each grid, and obtaining the grid label value of the grid portrait include:
[0043] Step S103a, selecting the grid label of the grid portrait;
[0044]Step S103b, extracting the big data of the portrait within the set time;
[0045] Step S103c, digitize the grid label according to the big data, so as to obtain the label value of the grid label.
[0046] Specifically: in order to make a 360-degree portrait of the grid divided in the previous step, it is necessary to fully mine the online and offline behavior of the crowd in the grid, the type of grid POI, and the number of visitors. Here are about 300 grid portrait tags, including the total number of resident population, total working population, gender ratio, age distribution of the overall population, education, consumption ability, income ability, consumer product level, values, and different types of POIs in the grid. The total number, the number of visitors, etc., make a multi-grained portrait of the grid. The minimum update period for each label is days. The grid labels are digitized and used as feature variables for the algorithm.
[0047] Step S104, guiding the user to input the weight value of the grid label of the grid portrait;
[0048] All the labels of the grid portrait will be used as feature variables to participate in the model algorithm, but for users in different industries, he focuses on different points, that is, different feature variables contribute differently to the site selection of different industries. The size of the contribution can be adjusted by setting the weight coefficient for the feature variable. For example, if the user chooses a location for a 4S store, then the characteristic variables that have nothing to do with it can be eliminated and will not participate in the calculation of the algorithm; some characteristic variables related to it also have different correlations. Here, the human-computer interaction method is used. Different weights (0.4, 0.3, 0.2, 0.1) are given to each characteristic variable by the user's choice of different degrees of attention (focus attention, attention, general attention, weak attention) to each feature variable.
[0049] Step S105, according to the label value and weight value of the grid portrait, using digital image processing technology to convert each grid portrait into a grid picture;
[0050] Among them, see image 3 , image 3 It is a sub-flowchart of this embodiment, and the step S105 of converting each grid image into a grid image using digital image processing technology according to the label value and weight value of the grid image includes:
[0051] Step S105a, performing weighted multiplication of the label value and weight value of the grid image to generate a numerical matrix;
[0052] Step S105b, converting into a grid image according to the numerical matrix, where the numerical values ​​of the numerical matrix are the pixels of the image.
[0053] Specifically: extract the portraits of each grid for a continuous period of time (this embodiment chooses half a year), and after digitization, filter valid labels as feature variables according to user needs, and multiply each feature variable by its respective weight to generate a new value matrix. Treat these processed values ​​as the pixels of the image, and use digital image processing technology to convert them into grid pictures with industry attributes. In this example, the feature image corresponding to the grid where the area circled by the user belongs.
[0054] Step S106 , using an image similarity algorithm to find other grids whose similarity between the area circled by the user and the grid picture exceeds a preset value.
[0055] Among them, see Figure 4 , Figure 4 It is a sub-flow chart of the embodiment of the present invention, and the step S106 of using the image similarity algorithm to find other grids whose similarity between the area circled by the user and the grid picture exceeds a preset value includes:
[0056] Step S106a, scaling the grid pictures so that all the grid pictures have the same size;
[0057] Step S106b, performing grayscale processing on the scaled grid image;
[0058] Step S106c, calculating the average value of pixels in each row of the grid picture to obtain the feature value of each row;
[0059] Step S106d, calculating the variance of the eigenvalues ​​of each row in the grid picture to obtain the eigenvalues ​​of the grid picture; and
[0060] Step S106e, comparing the feature value of the grid picture with the feature value of a circled area, and the grid picture whose approximation degree exceeds the preset value is the recommended location area.
[0061] Specifically: After converting all the grids in the Beijing area into the feature pictures shown in the above figure in the previous step, in this step we will use the picture WX4g41.jpg to perform similarity calculations with other pictures to find out the ones with high similarity picture.
[0062] Image scaling, all images involved in the calculation must be scaled to the same size, which is agreed to be 256*256 in this embodiment. The size of the zoomed image is determined by the amount of information and complexity of the original image. If the amount of information is small and the complexity is low, it needs to be scaled smaller. If the amount of information is large and the complexity is high, it cannot be zoomed too small, and important information is easily lost. . Therefore, it is necessary to flexibly define and scale the size according to specific needs, and maintain a balance between efficiency and accuracy.
[0063] Grayscale processing. Under normal circumstances, the calculation of image similarity has nothing to do with color. In order to ensure the efficiency of the algorithm, it is uniformly processed as a grayscale image to reduce the complexity of later calculations.
[0064] Calculate the average value. The average value here refers to calculating the average value of pixels in each row of the image. Thus each average represents the characteristics of the row.
[0065] Calculate the variance, calculate the variance of all the average values ​​in a picture, and the resulting variance is the feature value of the picture. The variance can well reflect the fluctuation of the pixel features of each row and record the main information of the picture.
[0066] Variance comparison, after the above calculation, each picture will generate a feature value (variance). The comparison of image similarity is to compare the closeness of image variance. The variance of a set of data can judge the stability of the array, and the closeness of the variance of multiple sets of data can reflect the closeness of the fluctuation of each set of data. Here we don't pay too much attention to the size of the variance, but only to the difference between the variances of the two pictures. The smaller the variance, the more similar the images are.
[0067] In another embodiment, another method of commercial site selection is also disclosed, which is the same as the method of site selection in the above-mentioned embodiment, the only difference is: the use of the image similarity algorithm to find the location selected by the user After the step S106 of other grids whose similarity between a region and the grid picture exceeds the preset value, it also includes:
[0068] Output other networks that exceed the preset value in order according to the degree of approximation;
[0069] According to the order of the degree of approximation, the color from dark to light is displayed on the map for the recommended site selection area.
[0070] For example: after obtaining the similarity between the grid selected by the user and the portrait features of all the grids in the Beijing area, output the top N grids and the similarity size (percentage system) according to the user's needs,
[0071] According to the specific geohash ID (that is, the picture name after removing .jpg), the specific grid position can be retrieved on the map. The similarity is the recommendation degree of the algorithm. Users can select the corresponding area according to their needs for the next step Business marketing and other activities. The figure below is the recommendation effect diagram of the front-end page of the algorithm of the present invention. The red rectangle is the reference area circled by the user, and the other blue rectangles are the areas recommended by the algorithm of the present invention. The color from dark to light represents the degree of recommendation from strong to weak , 1/2/3/4/5 are recommended rankings.
[0072] see Figure 5 , Figure 5 It is a schematic diagram of a commercial site selection device disclosed in an embodiment of the present invention. The commercial site selection device includes:
[0073] The receiving unit 101 receives an area circled on the city map input by the user, and the circled area is a reference area for site selection;
[0074] The grid division unit 102 divides the above-mentioned city into several grids, wherein it is ensured that the circled area falls into a certain grid;
[0075] The grid portrait unit 103 extracts the big data of the portrait within the set time, uses the big data to perform grid portraits on each grid, and obtains the tag value of the grid label of the grid portrait;

[0081] The grid image generation unit 105 converts each grid image into a grid image using digital image processing technology according to the label value and weight value of the grid image; and
[0082] The selection unit 106 uses an image similarity algorithm to find other grids whose similarity between the area circled by the user and the grid picture exceeds a preset value.
[0083] Wherein, in another embodiment, as in this embodiment, the selection unit 106 includes:

[0095] The internal memory 504 provides an environment for the operation of the computer program 5032 in the non-volatile storage medium 503. When the computer program 5032 is executed by the processor 502, the processor 502 can be executed to perform the following steps: An area circled above, the area selected by the circle is the reference area for site selection; the above-mentioned city is divided into several grids, wherein, it is ensured that the area selected by the circle falls into a certain grid; the extraction design The big data of the portrait within a certain period of time, use the big data to make a grid portrait of each grid, and get the label value of the grid label of the grid portrait; guide the user to input the weight value of the grid label of the grid portrait; according to the The tag value and weight value of the grid portrait, using digital image processing technology to convert each grid portrait into a grid picture; and using the image similarity algorithm to find the area circled by the user and the grid picture Other meshes whose approximation exceeds the preset value.
[0096] The specific implementation process is as follows:
[0097] Please refer to the attached figure 1 , with figure 1 It is a flow chart of a method for selecting a commercial location provided by an embodiment of the present invention, and the method for selecting a commercial location includes the following steps:
[0098] Step S101, the computer receives a circled area on the city map input by the user, and the circled area is a reference area for site selection.
[0099] For example: the urban grid similarity algorithm based on digital image recognition technology, relying on the big data platform, images the data with grid attributes, and accurately and efficiently calculates the similarity relationship between grids through image recognition technology. The application scenario of the embodiment of the present invention is that the user circles a plot in the Beijing Guomao area on the electronic map of the computer terminal, and the purpose is to find several other similar plots in the Beijing area for commercial activities. The specified area is the reference area.
[0100] Step S102. Divide the above-mentioned city into several grids, and ensure that the circled area falls into a certain grid.
[0101] In this embodiment, the mature geohash algorithm needs to be used for urban gridding. Divide the entire Beijing map into several grids of standard size. The plots circled by the user can fall into one of the grids, and then other similar grids are recommended to the user through the algorithm of the present invention.
[0102] Step S103 , extract big data of the portrait within a set time, use the big data to make a grid portrait of each grid, and obtain the label value of the grid label of the grid portrait.
[0103] Among them, see figure 2 , figure 2 It is a sub-flow chart of the embodiment of the present invention, the step S103 of extracting the big data of the portrait within the set time, using the big data to make a grid portrait of each grid, and obtaining the grid label value of the grid portrait include:
[0104] Step S103a, selecting the grid label of the grid portrait;
[0105] Step S103b, extracting the big data of the portrait within the set time;
[0106] Step S103c, digitize the grid label according to the big data, so as to obtain the label value of the grid label.
[0107] Specifically: in order to make a 360-degree portrait of the grid divided in the previous step, it is necessary to fully mine the online and offline behavior of the crowd in the grid, the type of grid POI, and the number of visitors. Here are about 300 grid portrait tags, including the total number of resident population, total working population, gender ratio, age distribution of the overall population, education, consumption ability, income ability, consumer product level, values, and different types of POIs in the grid. The total number, the number of visitors, etc., make a multi-grained portrait of the grid. The minimum update period for each label is days. The grid labels are digitized and used as feature variables for the algorithm.
[0108] Step S104, guiding the user to input the weight value of the grid label of the grid portrait;
[0109] All the labels of the grid portrait will be used as feature variables to participate in the model algorithm, but for users in different industries, he focuses on different points, that is, different feature variables contribute differently to the site selection of different industries. The size of the contribution can be adjusted by setting the weight coefficient for the feature variable. Here, the human-computer interaction method is adopted, and different weights (0.4, 0.3, 0.2, 0.1) are given to each feature variable by the user's choice of different degrees of attention (focused attention, attention, general attention, and weak attention).
[0110] Step S105, according to the label value and weight value of the grid portrait, using digital image processing technology to convert each grid portrait into a grid picture;
[0111] Among them, see image 3 , image 3 It is a sub-flowchart of this embodiment, and the step S105 of converting each grid image into a grid image using digital image processing technology according to the label value and weight value of the grid image includes:
[0112] Step S105a, performing weighted multiplication of the label value and weight value of the grid image to generate a numerical matrix;
[0113] Step S105b, converting into a grid image according to the numerical matrix, where the numerical values ​​of the numerical matrix are the pixels of the image.
[0114] Step S106 , using an image similarity algorithm to find other grids whose similarity between the area circled by the user and the grid picture exceeds a preset value.

[0120] Step S106e, comparing the feature value of the grid picture with the feature value of a circled area, and the grid picture whose approximation degree exceeds the preset value is the recommended location area.
[0121] Specifically: After converting all the grids in the Beijing area into the feature pictures shown in the above figure in the previous step, in this step we will use the picture WX4g41.jpg to perform similarity calculations with other pictures to find out the ones with high similarity picture.
[0122] Image scaling, all images involved in the calculation must be scaled to the same size, which is agreed to be 256*256 in this embodiment. The size of the zoomed image is determined by the amount of information and complexity of the original image. If the amount of information is small and the complexity is low, it needs to be scaled smaller. If the amount of information is large and the complexity is high, it cannot be zoomed too small, and important information is easily lost. . Therefore, it is necessary to flexibly define and scale the size according to specific needs, and maintain a balance between efficiency and accuracy.
[0123] Grayscale processing. Under normal circumstances, the calculation of image similarity has nothing to do with color. In order to ensure the efficiency of the algorithm, it is uniformly processed as a grayscale image to reduce the complexity of later calculations.
[0124] Calculate the average value. The average value here refers to calculating the average value of pixels in each row of the image. Thus each average represents the characteristics of the row.
[0125] Calculate the variance, calculate the variance of all the average values ​​in a picture, and the resulting variance is the feature value of the picture. The variance can well reflect the fluctuation of the pixel features of each row and record the main information of the picture.
[0126] Variance comparison, after the above calculation, each picture will generate a feature value (variance). The comparison of image similarity is to compare the closeness of image variance. The variance of a set of data can judge the stability of the array, and the closeness of the variance of multiple sets of data can reflect the closeness of the fluctuation of each set of data. Here we don't pay too much attention to the size of the variance, but only to the difference between the variances of the two pictures. The smaller the variance, the more similar the images are.
[0127] In another embodiment, another method of commercial site selection is also disclosed, which is the same as the method of site selection in the above-mentioned embodiment, the only difference is: the use of the image similarity algorithm to find the location selected by the user After the step S106 of other grids whose similarity between a region and the grid picture exceeds the preset value, it also includes:
