Abstract
(EN) In the present invention: horizontal plane position data that is more accurate than horizontal plane position data indicating the position of a moving body on a horizontal plane obtained at each observation time is acquired, or vertical plane position data indicating the position of the moving body on a vertical plane is acquired; movement trajectory data indicating the movement trajectory of the moving body is generated on the basis of the acquired highly accurate horizontal plane position data or the acquired vertical plane position data; the movement trajectory data is analyzed and the position and the movement state of the moving body for each measurement time is estimated; measurement condition data indicating the measurement condition for a laser radar device for each of the measurement times is generated on the basis of the position and the movement state of the moving body for each of the measurement times; and collected data is corrected on the basis of the measurement condition data.
(FR) Dans la présente invention : des données de position de plan horizontal plus précises que des données de position de plan horizontal indiquant la position d'un corps mobile sur un plan horizontal obtenu à chaque instant d'observation sont acquises, ou des données de position de plan vertical indiquant la position du corps mobile sur un plan vertical sont acquises ; des données de trajectoire de mouvement indiquant la trajectoire de mouvement du corps mobile sont générées en fonction des données de position de plan horizontal hautement précises acquises ou des données de position de plan vertical acquises ; les données de trajectoire de mouvement sont analysées et la position et l'état de mouvement du corps mobile à chaque instant de mesure sont estimés ; des données d'état de mesure indiquant l'état de mesure d'un dispositif radar laser à chacun des instants de mesure sont générées en fonction de la position et de l'état de mouvement du corps mobile à chacun des instants de mesure ; et des données collectées sont corrigées en fonction des données d'état de mesure.
(JA) 観測時刻ごとに得られる移動体の水平面上での位置を示す水平面位置データよりも高精度の水平面位置データを取得するか、または、移動体の鉛直面上での位置を示す鉛直面位置データを取得し、取得した高精度の水平面位置データ、または、取得した鉛直面位置データに基づいて、移動体の移動軌跡を示す移動軌跡データを生成し、移動軌跡データを解析して、測定時刻ごとの移動体の位置及び移動状態を推定し、測定時刻ごとの移動体の位置及び移動状態に基づいて、測定時刻ごとのレーザレーダ装置の測定条件を示す測定条件データを生成し、測定条件データに基づいて収集データを補正する。
