Title: (EN) Resource estimation system and resource estimation method
(ZH) 资源推定系统以及资源推定方法
Abstract: front page image
(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) isprovided 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 apredetermined 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 the 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.
(ZH) 本发明高精度地根据自然电位来探索海底等水底的资源。资源推定系统(1)的计算机(70)具备:推定用信息取得部(71),取得表示在水中的多个位置计测出的、具有规定的位置关系的多个电位电极(21)的电位的电位信息;噪声去除部(73),使用该电位进行主成分分析或者独立成分分析,去除所计测出的电位中包含的噪声;以及资源推定部(74),根据去除了噪声的电位,对水底资源的存在进行推定。
