Information processing device, information processing method, and non-transitory computer readable storage medium

An information processing method causing a computer to perform steps comprising:

• acquiring, by the computer, time-series position information obtained by a terminal device;
• determining, by the computer, whether relation between one or more pieces of interest position information included in the acquired time-series position information and prior or posterior position information in time series satisfy a predetermined criterion, the predetermined criterion indicating that no deviation is generated between the interest position information and the prior or posterior position information;
• and
• determining, by the computer, whether to hold the interest position information based on a determination result, wherein:
• upon determining that the predetermined criterion is unsatisfied, the computer does not hold the interest position information.

A non-transitory computer readable storage medium having stored therein a computer program that causes a processor to perform steps comprising:

• acquiring, by the processor, time-series position information obtained by a terminal device;
• determining, by the processor, whether relation between one or more pieces of interest position information included in the acquired time-series position information and prior or posterior position information in time series satisfy a predetermined criterion, the predetermined criterion indicating that no deviation is generated between the interest position information and the prior or posterior position information;
• and
• determining, by the processor, whether to hold the interest position information based on a determination result, wherein:
• upon determining that the predetermined criterion is unsatisfied, the processor does not hold the interest position information.

An information processing device, comprising:

• a processor programmed to:
• acquire time-series position information acquired by a terminal device;
• determine whether relation between one or more pieces of interest position information included in the acquired time-series position information and prior or posterior position information in time series satisfy a predetermined criterion;
• and
• determine whether to hold the interest position information based on a determination result, wherein:
• the processor determines whether a time interval between the interest position information and position information temporally posterior to the interest position information is less than a first time, and when determining that the time interval is less than the first time, determines not to hold the interest position information,
• the processor determines whether the time interval between the interest position information and the position information temporally posterior to the interest position information is a second time that is longer than the first time or more, and when determining that the time interval is the second time or more, determines to hold the interest position information, and
• when determining that the time interval between the interest position information and the position information temporally posterior to the interest position information is less than the second time that is longer than the first time, the processor determines whether the time interval between the interest position information and position information temporally prior to the interest position information is a third time or more, and when determining that the time interval is the third time or more, determines to hold the interest position information.
