Description

  Embodiments described herein relate generally to a technique for analyzing a flow line indicating a moving locus of a moving object, for example, a person.

  A system for generating a flow line indicating a trajectory of a customer who has moved in a store such as a supermarket or a convenience store is already known. By analyzing the flow lines generated by this system, the customer's purchasing behavior can be confirmed. For example, the movement distance in the store can be known from the total length of the flow line, so-called flow line length. Further, the staying time in the store can be known from the time difference from the start time to the end time of the flow line. If the travel distance and the staying time are long, the customer may have an opportunity to purchase many products. Therefore, from the store side, further improvement in sales can be expected by improving the sales floor.

JP 2003-1000047 A

  However, even if the movement distance and stay time of customers obtained from the flow lines generated by different flow line generation systems are almost the same value, it is the same if the area of the sales floor that is the flow line monitoring area is different. Cannot be evaluated. For example, it is assumed that the movement distance (flow line length) is the same 40 meters in a store with a sales floor area of 1000 square meters and a store with 100 square meters. In this case, it is considered that there are few opportunities to purchase merchandise because it corresponds to the customer passing through the former store. On the other hand, in the latter store, it corresponds to the customer making a round of the store, so it is considered that there are many opportunities to purchase products. Therefore, it can be evaluated that the latter store has higher sales floor productivity than the former store. The same can be said about staying time.

According to one embodiment, the flow line analysis device uses the set values of the items of the outer peripheral length of the sales floor, the total passage length, the number of items, and the total sales amount as parameters for normalization calculation for each store to be monitored. A stored parameter table; means for selecting an arbitrary set value as a parameter for normalization calculation from set values of each item registered in the parameter table; and a store floor of the store registered in the parameter table Obtained as a monitoring area, an analysis flow line acquisition means for acquiring flow line data including information indicating a movement locus of a moving body moving in the monitoring area and time information of the locus, and obtained by the analysis flow line acquisition means. A moving distance calculating means for calculating a moving distance in the monitoring area of the moving body from information indicating the moving locus included in the flow line data, and the moving distance of the monitoring area, A normalization calculation means for dividing the set value determined by the parameter as a calculation parameter and normalizing, and a normalized data output means for outputting the data of the travel distance normalized by the normalization calculation means It is characterized by that .

Hereinafter, embodiments will be described with reference to the drawings.
FIG. 1 is a block diagram of the present embodiment. The present embodiment includes a flow line analyzer 1 realized by a personal computer or the like. The flow line analyzer 1 is connected to flow line generation systems 3A, 3B,..., 3Z respectively constructed in a plurality of stores A, B,.

  The flow line generation systems 3 </ b> A to 3 </ b> Z track customers moving in the store, which is a monitoring area, and generate flow line data D <b> 1 indicating the movement trajectory for each customer. There are a method using, a method using a multi-laser scanner, and the like. This embodiment may employ any method.

  The structure of the flow line data D1 is shown in FIG. As shown in FIG. 2, the flow line data D1 includes a flow line ID and n sets of coordinate i / time i data (n> 1, 1 ≦ i ≦ n). The flow line ID is information generated by each of the flow line generation systems 3A to 3Z in order to individually identify each flow line data. The coordinate i / time i data is the data of each sampling point when sampling the movement trajectory from the point (start point) where the customer, who is a moving object, was first detected to the point (end point) where it was last detected, at unit time intervals. Coordinate and time data. The coordinates are two-dimensional coordinates or three-dimensional coordinates in the world coordinate system with the reference point set in advance for the monitoring area as the origin.

  The flow line generation systems 3 </ b> A to 3 </ b> Z generate a new flow line ID when detecting a customer (moving body) moving in the store that is the monitoring area. Then, the flow line data D1 is generated by attaching the coordinate i / time i data from the start point (i = 1) to the end point (i = n) of the customer in time series to the flow line ID. The flow line generation systems 3A to 3Z store and store the generated flow line data D1 in the respective flow line databases 4A, 4B, ..., 4Z.

  The flow line analyzer 1 includes an input unit 11, a display unit 12, a communication unit 13, a program storage unit 14, a data storage unit 15, a file storage unit 16, and a control unit 17. The input unit 11 includes input devices such as a keyboard and a mouse. The display unit 12 includes a display device such as a liquid crystal display or a CRT display. By using a display with a touch panel, the input unit and the display unit may be combined. The communication unit 13 performs data communication with each of the flow line generation systems 3A to 3Z via the communication network 2, and reads the flow line data from the flow line databases 4A to 4Z.

  For example, the program storage unit 14 configured by a ROM (Read Only Memory) stores a flow line analysis program for controlling the processing operation of the flow line analysis apparatus 1. For example, the data storage unit 15 configured by a RAM (Random Access Memory) temporarily stores the flow line data D1 read as analysis targets from the flow line generation systems 3A to 3Z.

  For example, the file storage unit 16 composed of an HDD (Hard Disk Drive) stores flow line analysis files 16A, 16B,. FIG. 3 is a diagram showing a data structure of the flow line analysis data D2 described in the flow line analysis files 16A, 16B,..., 16Z. As shown in FIG. 3, the flow line analysis data D2 includes item data such as a store code, a flow line ID, a travel distance, a stay time, a standardized travel distance, and a standardized stay time. The store code is a unique code set in advance for each store in order to identify each store AZ. The travel distance, stay time, standardized travel distance, and standardized stay time will be described later.

  For example, the control unit 17 configured by a CPU (Central Processing Unit) realizes at least the following functions 1 to 5 according to the flow line analysis program.

1. A function of acquiring the flow line data D1 stored in the flow line databases 4A to 4Z of the flow line generation systems 3A to 3Z (analysis flow line acquisition means).

2. A function (movement distance calculation means) for calculating a movement distance within a monitoring area of a customer as a moving body from information indicating a movement locus included in the flow line data D1.

3. A function for calculating the staying time in the monitoring area of the customer as a moving object (staying time calculating means) from the time information included in the flow line data D1.

4). A function of normalizing by dividing the calculated travel distance and stay time by a predetermined parameter related to the monitoring area (standardization computing means).

5. A function (standardized data output means) for outputting standardized travel distance and dwell time data.

  In particular, the flow line analyzer 1 stores the parameter setting table (parameter storage means) 5 having the data structure shown in FIG. As shown in FIG. 4, the parameter setting table 5 includes numerical values related to the items of the outer peripheral length, the total passage length, the number of items, and the total sales amount for each store A to Z in which the flow line generation systems 3A to 3Z are constructed. Save settings.

  The outer peripheral lengths a1, b1, c1,..., Z1 are distances on the outer periphery of the sales floor (monitoring area) monitored by the flow line generation systems 3A to 3Z of the corresponding stores A to Z. The total passage lengths a2, b2, c2,..., Z2 are total distances of customer passages formed in the sales floor. The product scores a3, b3, c3,..., Z3 are the total scores of products displayed on the sales floor. The total amounts a4, b4, c4,..., Z4 are total amounts of commodities sold on the sales floor. In addition, as for the product score and the total sales amount, data of a preset reference date (for example, the first day of every month) is stored in the parameter setting table 5.

  The flow line analysis apparatus 1 uses, as parameters, setting values of items arbitrarily designated by the user from among the items set in the parameter setting table 5 (peripheral length, total passage length, product points, total sales amount). Use to normalize travel distance and stay time between stores AZ. For this reason, the flow line analyzer 1 includes a standardized item selection job as one of the job menus.

  When the start of the standardized item selection job is commanded by the input of the input unit 11, the control unit 17 starts the standardized item setting process of the procedure shown in the flowchart of FIG. First, the control unit 17 causes the display unit 12 to display a list screen of each item set in the parameter setting table 5 (ST1). Then, it waits for any one item to be selected (ST2). When any item is selected by the input of the input unit 11 (YES in ST2), the control unit 17 uses a code for identifying the selected item (hereinafter referred to as a normalization code) as a data storage unit. 15 (ST3). Thus, the control unit 17 ends the standardized item setting process.

When the standardized item setting process is completed, the flow line analysis apparatus 1 can execute the flow line analysis work. The flow line analysis work is performed for each store.
When the start of the flow line analysis work is instructed by the input of the input unit 11, the control unit 17 starts the flow line analysis process of the procedure shown in the flowchart of FIG. First, the control part 17 displays the list screen of each shop AZ on the display part 12 (ST11). And it waits for any one store to be selected (ST12).

  When one of the stores X is selected by the input of the input unit 11 (YES in ST12), the control unit 17 accesses the flow line generation system 3X of the selected store X via the communication unit 13 to generate a flow line. Request data download. In response to this request, the flow line generation system 3X downloads the flow line data group stored in the flow line database 4X to the flow line analyzer 1, so that the control unit 17 stores the downloaded flow line data group. The data storage unit 15 temporarily stores it (ST13).

  The control unit 17 acquires the standardized code from the data storage unit 15. And the setting value with respect to the selection store X of the item identified by the said normalization code is read from the parameter setting table 5 as a normalization parameter (ST14: parameter reading means).

  The control unit 17 creates a new flow line analysis file 16X for the selected store X. This file 16X is distinguished from the past file for the same store by including the date of the day in the file name, for example (ST15).

  The control unit 17 reads out the flow line data to be analyzed from the downloaded flow line data group (ST16: analysis flow line acquisition means). First, among the n sets of coordinate / time data included in the flow line data, the distance d1 between the coordinates 1 and 2 is calculated from the coordinates 1 of the head data and the coordinates 2 of the second data. Next, a distance d2 between the coordinates 2 and 3 is calculated from the coordinates 2 of the second data and the coordinates 3 of the third data. Thereafter, similarly, the distance from the coordinates of the next data is calculated sequentially. When the distance d (n−1) between the coordinate (n−1) of the (n−1) th data and the coordinate n of the nth data is calculated in this way, the control unit 17 determines each distance d1, d2,. , D (n−1) are added together to calculate the movement line length, that is, the movement distance of the customer specified by the movement line ID of the movement line data (ST17: movement distance calculation means).

  The control unit 17 calculates the normalized movement distance by dividing the movement distance calculated in the process of step ST17 by the normalization parameter acquired in the process of step ST14 (ST18: normalization calculation means).

  Further, the control unit 17 among the n sets of coordinate / time data included in the flow line data to be analyzed, the time difference between the time 1 of the first data and the time n of the nth data, that is, the flow line of the flow line data. The stay time of the customer specified by the ID is calculated (ST19: stay time calculation means). Then, the stay time is similarly divided by the normalization parameter to calculate the normalized stay time (ST20: normalization calculation means).

  The control unit 17 stores the store code selected in the process in step ST11, the flow line ID included in the flow line data to be analyzed, and the movement calculated in each process in steps ST17, 18, 19, and 20, respectively. The distance, the standardized travel distance, the stay time, and the standardized stay time are described in the flow line analysis file 16X generated by the process of step ST15 (ST21: standardized data output means).

  Thereafter, the control unit 17 determines whether or not the flow line data to be analyzed remains in the downloaded flow line data group (ST22). When remaining (NO in ST22), the control unit 17 reads the flow line data (ST16). And the process of said step ST17-ST21 is performed with respect to this flow line data.

  On the other hand, when no flow line data to be analyzed remains in the downloaded flow line data group (YES in ST22), the control unit 17 stores the flow line analysis file 16X in the file storage unit 16. (ST23).

  As described above, the flow line analysis apparatus 1 according to the present embodiment, for example, uses the movement line data for each customer generated by the flow line generation system 3A of the store A, so that the moving distance and stay of the customer moving in the monitoring area of the store A Time is calculated for each customer. Further, the travel distance and the stay time are normalized by dividing by the standardization parameters set in the store A, respectively. Then, the standardized travel distance and stay time are output to the flow line analysis file 16A of the store A as the flow line analysis data together with the travel distance and stay time before normalization.

  Similarly, the flow line analyzer 1 uses the flow line data for each customer generated by the flow line generation system 3B of the store B to determine the movement distance and stay time of the customers moving in the monitoring area of the store B for each customer. To calculate. Further, the travel distance and the stay time are normalized by dividing by the standardization parameters set in the store B, respectively. Then, the standardized travel distance and stay time are output to the flow line analysis file 16B of the store B as flow line analysis data together with the travel distance and stay time before normalization.

  The standardization parameters include an outer peripheral length, a total passage length, a product score, and a total sales amount, and can be arbitrarily selected by the user. The outer peripheral length usually has a larger value when the monitoring area of the flow line generation system, that is, the sales floor area is wider.

  For example, it is assumed that the outer peripheral length a1 of the store A is 100 meters and the outer peripheral length b1 of the store B is 50 meters. Each flow line length of the flow line data generated by the flow line generation system 3A of the store A and the flow line data generated by the flow line generation system 3B of the store B, that is, the moving distance of the customer is 50 meters. Suppose there was. Then, the standardized travel distance obtained by analyzing the flow line data of the store A is “0.5”, and the standardized travel distance obtained by analyzing the flow line data of the store B is “1”. . Therefore, it can be evaluated that the store B has more opportunities to purchase products than the store A.

  In addition, it is assumed that the stay time of each customer obtained from each flow line data is 25 minutes. In this case, the standardized stay time obtained by analyzing the flow line data of the store A is “0.25”, and the standardized stay time obtained by analyzing the flow line data of the store B is “0.5”. " Therefore, it can be evaluated that the store B has more opportunities to purchase products than the store A.

  As for other standardized parameters, that is, the total passage lengths a2 and b2, the product points a3 and b3, and the total sales amounts a4 and b4, the larger sales area usually has a larger value. Therefore, even if an item other than the total passage length is selected as the standardization parameter, the sales floor productivity of each store can be properly evaluated.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above-described embodiment, the items of the normalization parameter are exemplified by the outer peripheral length, the total passage length, the number of products, and the total sales amount, and can be arbitrarily selected by the user. However, you may design the flow line analyzer 1 so that any one item may be used fixedly. In this case, the parameter setting table 5 shown in FIG. 4 can be dispensed with. Also, the standardized item setting process of the procedure shown in the flowchart of FIG. 5 is not necessary. Therefore, the flow line analysis work of the procedure shown in the flowchart of FIG. 6 can be executed at any time.

  Note that the processing procedure of the flow line analysis work is not limited to the procedure shown in the flowchart of FIG. For example, if the flow line data to be analyzed is read (ST16), the stay time is calculated from this flow line data (ST19), and the stay time is normalized (ST20). Next, the movement distance is calculated from the flow line data (ST17), and the movement distance is normalized (ST18). Alternatively, the travel distance and stay time are calculated from the flow line data (ST17, 19), and then the travel distance and stay time are normalized (ST18, 20).

  Moreover, although the said embodiment demonstrated the normalized data output means as an output means to the flow line analysis files 16A-16Z, it is not limited to this. For example, a display output unit for the display unit 12 or a print output unit for a printing unit (not shown) may be used.

  Moreover, in the said embodiment, although the case where the program which is a function which implements invention was recorded beforehand was demonstrated in the said apparatus, the same program may be downloaded from a network to an apparatus not only this, A program in which a similar program is stored in a recording medium may be installed in the apparatus. The recording medium may be any form as long as the recording medium can store the program and can be read by the apparatus, such as a CD-ROM. In addition, the function obtained by installing or downloading in advance may be realized in cooperation with an OS (operating system) inside the apparatus.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, the constituent elements over different embodiments may be combined.
