Title:
INFORMATION PROCESSING DEVICE, ANALYSIS SYSTEM, DATA AGGREGATION METHOD, AND COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/194421
Kind Code:
A1
Abstract:
An information processing device (100) that comprises an acquisition unit (110) that acquires first time series data that includes presence area information for a target space for at least one subject that is included in a plurality of images that are captured from the target space during a prescribed period, a data set generation unit (120) that, from the presence area information in the first time series data for a specific subject, generates a plurality of data sets for a plurality of different durations from the start time of the prescribed period, an estimation unit (130) that, on the basis of the presence area information included in each of the plurality of data sets, estimates, for each of the plurality of durations, the analytical precision of a distribution for the subject within the target space were aggregation onto representative data performed from the respective data set, a determination unit (140) that, on the basis of the analytical precisions and the degrees of data reduction that would result from aggregation from the data sets, determines a duration to be aggregated, and an aggregation unit (150) that aggregates the data set that corresponds to the determined duration onto the representative data.
