Abstract
(EN) In order to accurately estimate the body weight of a person walking, this body weight estimation device is provided with a data receiving unit which receives gait data including walking characteristics of the person walking, a first measurement unit which, from the gait data, extracts feature values based on the walking characteristics of the person walking, a second measurement unit which uses the gait data as sample data to generate a learning model by learning the correlation between the feature values extracted by the first calculation unit and body weight information of the person walking, and an estimation unit which inputs gait data of the estimation target into the learning model to estimate body weight information corresponding to the gait data of the estimation target.
(FR) Afin d'estimer avec précision le poids corporel d'une personne marchant, ce dispositif d'estimation de poids corporel est pourvu d'une unité de réception de données qui reçoit des données de démarche comprenant des caractéristiques de marche de la personne marchant, une première unité de mesure qui, à partir des données de démarche, extrait des valeurs de caractéristiques sur la base des caractéristiques de marche de la personne marchant, une seconde unité de mesure qui utilise les données de démarche comme données d'échantillon pour générer un modèle d'apprentissage par apprentissage de la corrélation entre les valeurs de caractéristiques extraites par la première unité de calcul et des informations de poids corporel de la personne marchant, et une unité d'estimation qui entre des données de démarche de la cible d'estimation dans le modèle d'apprentissage pour estimer des informations de poids corporel correspondant aux données de démarche de la cible d'estimation.
(JA) 歩行者の体重を高精度に推定するために、歩行者の歩行特性を含む歩容データを受信するデータ受信部と、歩容データから歩行者の歩行特性に基づいた特徴量を抽出する第1計算部と、歩容データをサンプルデータに用いて、第1計算部によって抽出された特徴量と歩行者の体重情報との相関関係を学習して学習モデルを生成する第2計算部と、推定対象の歩容データを学習モデルに入力して推定対象の歩容データに対応する体重情報を推定する推定部とを備える体重推定装置とする。
