Title:
浮子軌跡取得システム
Document Type and Number:
Japanese Patent JP6670111
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To measure a trajectory of a float, a flow velocity, a distance of movement or a water level.SOLUTION: A float trajectory acquisition system comprises: an imaging apparatus for imaging a float to generate imaging angle information indicating an imaging angle and image data; an imaging control device for controlling the imaging angle in such a manner that an image of the float is positioned within a predetermined region in the image data; a distance measurement device which transmits an electromagnetic wave, generates distance information by measuring a linear distance to the float by receiving a reflection wave from the float, and changes a direction of an electromagnetic wave to be transmitted in accordance with the imaging angle of the imaging apparatus; and a processor which receives the distance information generated by the distance measurement device at multiple time points, receives the imaging angle information generated by the imaging apparatus at the multiple time points, and acquires trajectory data indicating a trajectory of movements of the float during the multiple time points based on the received distance information and imaging angle information.SELECTED DRAWING: Figure 1
