Abstract

The invention provides a data collecting method and device. The data collecting method includes: collecting first and second sensor data respectively through a first and a second sensors while a datacollecting apparatus moves within a target area, and tagging a first and a second timestamp values respectively to the first and the second sensor data; generating map data of the target area and location data at a point of time corresponding to the first timestamp value, based on the first sensor data; generating map information of the target area based on the map data, and generating moving pathinformation on the map based on the location data; and estimating a sensing location at a point of time corresponding to the second timestamp value based on the moving path information, and tagging the sensing location to the second sensor data.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2018-0116177 filed with the Korean Intellectual Property Office on September 28, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] One or more embodiments relate to a method and system for collecting data, and more particularly, to a method and system for collecting sensor data tagged with an indoor location. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] In order to provide location-based services to users, it is necessary to obtain accurate location information of users or target objects. Such location information is typically obtained based on Global Positioning System (GPS) signals. However, it is difficult to measure the position of a user or a target object in a GPS signal gray area such as ...
