FIELD: measurement equipment.
SUBSTANCE: group of inventions relates to a method of optic investigation of a wind-driven power plant or its part, namely a screw blade, and to an investigation device for implementation of the above method. The method involves levelling of a chamber for the investigated area and photographing of the investigated area by the chamber. Then, recording of the position of the photographic area and comparison of the detected position to the photographic area is performed.
EFFECT: reduction of time consumption and costs for performance of an investigation, as well as automation of the investigation and exclusion of risk of elevated jobs.
