Solution Overview

Problem

Conventional devices fail to properly sort and manage position information, leading to inefficiencies in data storage and analysis.

Innovation Solution

An information processing device acquires time-series position information from terminal devices and determines whether the relation between interest position information and prior or posterior information satisfies predetermined criteria, such as time intervals, distances, moving speeds, and angles, to decide whether to hold or discard the position information.

1Measurement precision

If conventional filtering methods are applied to reduce deviation in traveling locus information, then the deviation between traveling locus information and reference locus information is reduced, but the position information cannot be properly sorted

Solution Approach 1:

The patent segments position information processing into distinct stages: acquisition of time-series position information, determination of relationships between interest position information and prior/posterior information, and selective holding based on predetermined criteria. This segmentation enables proper sorting while maintaining accuracy.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary determination of relationships between position information points before final data storage. By evaluating time intervals, distances, and movement patterns in advance, the system sorts position information properly while ensuring accuracy requirements are met.

AI summary

An information processing device according to the present application includes an acquisition unit and a determination unit. The acquisition unit acquires time-series position information acquired by a terminal device. The determination unit determines whether relation between one or more pieces of interest position information included in the time-series position information acquired by the acquisition unit and prior or posterior position information in time series satisfies a predetermined criterion, and determines whether to hold the interest position information based on a determination result.
