INFORMATION COLLABORATION SYSTEM

WIPO Patent Application WO/2019/142820

A1

A sensor device (11) for a mounted device (1) detects sensor detection values. Sensor information includes sensor detection values and the detection time. A mobile terminal (2) receives sensor information and positioning information from the mounted device (1). An information synchronization unit (252) for the mobile terminal (2) synchronizes the positioning information and the sensor information if the time difference between the detection time and an acquisition time included in the positioning information is a prescribed value or less than the prescribed value. The positioning information includes a position obtained by positioning information acquisition units (12), (21) and the acquisition time at which the position was obtained. A traveling body position estimation unit (253) estimates a traveling body position from the positioning information and sensor information synchronized by the information synchronization unit (252).
