Title (EN) RESOURCE ESTIMATION SYSTEM AND RESOURCE ESTIMATION METHOD
(FR) SYSTÈME D'ESTIMATION DE RESSOURCES ET PROCÉDÉ D'ESTIMATION DE RESSOURCES
(JA) 資源推定システム及び資源推定方法
Abstract:
(EN) The present invention precisely searches for resources at the bottom of water such as the seafloor, on the basis of natural electric potentials. A computer 70 of a resource estimation system 1 is provided with: an information-for-estimation acquisition unit 71 that acquires electric potential information indicating the electric potentials of a plurality of potential electrodes 21 having a predetermined positional relationship thereamong, the electric potentials being measured at a plurality of underwater positions; a noise removal unit 73 that removes noise included in the measured electric potentials by conducting principal component analysis or independent component analysis using said electric potentials; and a resource estimation unit 74 that estimates the presence of a resource at the bottom of water on the basis of the denoised electric potentials.
(FR) L'invention concerne précisément des recherches de ressources au fond de l'eau, tel que le plancher sous-marin, sur la base de potentiels électriques naturels. Un ordinateur 70 d'un système d'estimation de ressources 1 comprend : une unité d'acquisition d'informations pour estimation 71 qui acquiert des informations de potentiel électrique indiquant les potentiels électriques d'une pluralité d'électrodes de potentiel 21 ayant une relation de position prédéterminée entre elles, les potentiels électriques étant mesurées au niveau d'une pluralité de positions sous-marines ; une unité d'élimination de bruit 73 qui élimine le bruit inclus dans les potentiels électriques mesurés par réalisation d'une analyse de composante principale ou d'une analyse de composante indépendante à l'aide desdits potentiels électriques ; et une unité d'estimation de ressources 74 qui estime la présence d'une ressource au fond de l'eau sur la base des potentiels électriques débruités.
(JA) 自然電位に基づく海底等の水底の資源の探索を精度よく行う。 資源推定システム1のコンピュータ70は、水中における複数の位置で計測された、所定の位置関係を有する複数の電位電極21の電位を示す電位情報を取得する推定用情報取得部71と、当該電位を用いて、主成分分析又は独立成分分析を行って、計測された電位に含まれるノイズを除去するノイズ除去部73と、ノイズが除去された電位に基づいて、水底における資源の存在を推定する資源推定部74とを備える。
