Title:
SPEED CALCULATION DEVICE, SPEED CALCULATION METHOD, AND SPEED CALCULATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/153248
Kind Code:
A1
Abstract:
The present disclosure provides a speed calculation device with which it is possible to accurately calculate speed corresponding to the movement of an electronic device. The speed calculation device (100) according to the present disclosure comprises a sensor information acquisition unit (111), a speed estimation unit (112), an average speed calculation unit (113), a relationship information calculation unit (114), and a speed-determining unit (115). The sensor information acquisition unit (111) acquires, from an acceleration sensor, sensor information relating to acceleration regarding an electronic device. The speed estimation unit (112) calculates, on the basis of the sensor information, an estimated speed estimated with respect to the movement of the electronic device. The average speed calculation unit (113) performs filtering and integration on the sensor information and calculates an average speed corresponding to the movement of the electronic device. The relationship information calculation unit (114) calculates relationship information indicating the correspondence relationship between the estimated speed and the average speed. The speed-determining unit (115) determines the speed corresponding to the current movement of the electronic device on the basis of the relationship information and the current estimated speed calculated by the speed estimation unit.
