Title:
MONITORING SYSTEM AND MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/244752
Kind Code:
A1
Abstract:
A monitoring system (100) comprises: an imaging device (11) that captures image information (31) of a blade (73) constituting a wind turbine (70); and a control device (21) that controls the imaging device (11) to capture the image information (31) and that stores the captured image information (31) in a storage unit (30). The control device (21) instructs the imaging device (11) with imaging parameter information for when the image information (31) of the blade (73) is to be captured, thereby causing the imaging device (11) to capture the image information (31) after moving to an imaging position that matches the imaging parameter information. The imaging parameter information includes a separation distance at which focus is achieved and which is the distance from the imaging device (11), on an R cross-section which is a plane perpendicular to an R-axis that is the longitudinal direction of the blade (73), to the blade (73) on the same R cross-section.
