Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/002320
Kind Code:
A1
Abstract:
According to the present invention, in a display area (D) of a display device of a maneuvering device (30), the image (C) of a power transmission line as a subject is displayed. When the power transmission line is imaged from a position separated from the power transmission line by a predetermined distance, the relationship between the thickness of the image (C) of the power transmission line displayed on the display device of the maneuvering device (30) and the size of the display area D of the display device of the maneuvering device (30) is determined in advance. The interval between broken line guide images (A1), (A2) denotes the thickness of the power transmission line determined on the basis of the relationship. Further, an image corresponding to the power transmission line can be extracted from the captured image by a well-known image analysis method, and a solid line guide image (A3) is displayed at a position corresponding to the center of the power transmission line in the width direction. The operator maneuvers to adjust the distance between a flying object (10) and the transmission line, which is a subject, such that the image C of the power transmission line displayed on the display device of the maneuvering device (30) fits exactly between the guide images (A1), (A2).
