Abstract

A map generation apparatus includes a memory, and a processor configured to execute a procedure, the procedure including obtaining position data indicating positions of the terminal device during moving of the terminal device, and read-position data indicating a position at which the terminal device has read data from a recording medium during the moving of the terminal device, storing the position data and the read-position data in the memory, generating a map including the positions indicated by the position data, and displaying that an area on a side of the read-position data among areas set based on a path of the positions indicated by the position data is an area of disposition target of the recording medium, on the generated map.

Claims

1. A non-transitory computer-readable recording medium storing a map generation program that causes a computer to execute a procedure, the procedure comprising:

obtaining position data indicating positions of a terminal device during moving of the terminal device, and obtaining read-position data indicating positions at which the terminal device has read data from one or more recording mediums by scanning the one or more recording mediums during the moving of the terminal device;

generating a map including one or more paths that are defined based on the positions indicated by the position data; and

displaying, on the generated map, a disposition area of a target to which one of the recording mediums is attached on a side of one of the paths based on the read-position data, the side at which the disposition area is to be displayed being determined based on at least one of a side that includes a position corresponding to a regression line obtained by analyzing the read-position data.

2. The non-transitory recording medium according to claim 1, wherein the one or more paths are approximate lines acquired based on the position data.

3. The non-transitory recording medium according to claim 1, wherein the position data includes the read-position data.

4. The non-transitory recording medium according to claim 1, the procedure further comprising:

dividing the positions indicated by the position data into a plurality group of positions; and

determining the disposition area of the target to which each recording medium is attached in accordance with a positional relationship between paths indicated by positions included in each of the plurality groups and the position indicated by the read-position data.

5. The non-transitory recording medium according to claim 1, wherein the regression line is obtained by performing regression analysis on the read-position data.

6. The non-transitory recording medium according to claim 5, wherein the regression analysis is performed by using the least squares method on the read-position data.

7. The non-transitory recording medium according to claim 5, wherein the regression analysis is performed by one of a simple regression analysis to obtain a linear functional regression line and a multiple regression analysis to obtain one of a quadratic functional and a cubic functional regression line.

8. A map generation apparatus comprising:

a memory; and

a processor configured to execute a procedure, the procedure including;

obtaining position data indicating positions of a terminal device during moving of the terminal device, and obtaining read-position data indicating positions at which the terminal device has read data from one or more recording mediums by scanning the one or more recording mediums during the moving of the terminal device;

storing the position data and the read-position data in the memory;

generating a map including one or more paths that are defined based on the positions indicated by the position data; and

displaying, on the generated map, a disposition area of a target to which one of the recording mediums is attached on a side of one of the paths based on the read-position data, the side at which the disposition area is to be displayed being determined based on at least one of a side that includes a position corresponding to a regression line obtained by analyzing the read-position data.

9. The map generation apparatus according to claim 8, wherein the one or more paths are approximate lines acquired based on the position data.

10. The map generation apparatus according to claim 8, wherein the position data includes the read-position data.

11. The map generation apparatus according to claim 8, wherein the procedure further comprises:

dividing the positions indicated by the position data into a plurality groups of positions, and

determining the disposition area of the target to which each recording medium is attached in accordance with a positional relationship between paths indicated by positions included in each of the plurality groups and the position indicated by the read-position data.

12. A map generation method comprising:

obtaining position data indicating positions of a terminal device during moving of the terminal device, and obtaining read-position data indicating positions at which the terminal device has read data from one or more recording mediums by scanning the one or more recording mediums during the moving of the terminal device;

generating a map including one or more paths that are defined based on the positions indicated by the position data; and

displaying, on the generated map, a disposition area of a target to which one of the recording mediums is attached on a side of one of the paths based on the read-position data, the side at which the disposition area is to be displayed being determined based on at least one of a side that includes a position corresponding to a regression line obtained by analyzing the read-position data, using a processor.

13. The map generation method according to claim 12, wherein the one or more paths are approximate lines acquired based on the position data.

14. The map generation method according to claim 12, wherein the position data includes the read-position data.

15. The map generation method of displaying a map, according to claim 12 further comprising:

dividing the positions indicated by the position data into a plurality groups of positions, and

determining the disposition area of the target to which each recording medium is attached in accordance with a positional relationship between paths indicated by positions included in each of the plurality groups and the position indicated by the read-position data.

16. A map generation system comprising:

a terminal device including;

a first communication interface device; and

a first processor configured to execute a first procedure, the first procedure including;

reading out data from one or more recording mediums;

identifying positions of the terminal device periodically during moving of the terminal device, and positions at which the terminal device has read data from the one or more recording mediums by scanning the one or more recording mediums during the moving of the terminal device; and

generating position data indicating the positions of the terminal device, and read-position data indicating the position at which the terminal device has read data from the one or more recording mediums during the moving of the terminal device; and

a map generation apparatus including

a second communication interface device; and

a second processor configured to execute a second procedure, the second procedure including;

obtaining the group of position data and the read-position data from the terminal device via the first communication interface device and second communication interface device; and

generating a map including one or more paths that are defined based on the positions indicated by the position data; and

displaying, on the generated map, a disposition area of a target to which one of the recording mediums is attached on a side defined based on the read-position data, the side at which the disposition area is to be displayed being determined based on at least one of a side that includes a position corresponding to a regression line obtained by analyzing the read-position data.
