Abstract
A device for modeling blades comprises a data collection module configured to receive sensing data of a drone for a reference blade included in a wind turbine, and a modeling module configured to generate a blade model by performing modeling on the wind turbine based on the sensing data, wherein the modeling module comprises: a reference blade model generation unit configured to generate a reference blade model by performing modeling on the reference blade, and an other blade model generation unit configured to generate an other blade model for at least one other blade included in the wind turbine based on the reference blade model.
Claims12
A device for modeling blades comprising:
- a processor configured to:
- receive sensing data of a drone for a reference blade included in a wind turbine;
- and
- generate a blade model by performing modeling on the wind turbine based on the sensing data,
- wherein when generating the blade model, the processor is further configured to:
- generate a reference blade model by performing modeling on the reference blade, and
- generate another blade model for at least one other blade included in the wind turbine based on the reference blade model, and
- wherein the blade model comprises at least one of virtual straight line set along each of a plurality of surfaces included in the blade and a virtual coordinate system for each of the plurality of surfaces determined based on the virtual straight line,
- wherein the sensing data comprises photographing data captured by a camera included in the drone, and
- wherein the processor is further configured to:
- measure location data on a first measurement surface included in the reference blade using the photographing data, and
- set a virtual straight line for the first measurement surface based on the measured location data on the first measurement surface,
- wherein the processor is further configured to:
- based on a first time point of the photographing data,
- recognize a blade box from the photographing data,
- determine a center point of the recognized blade box,
- measure first location data, which is location data of the determined center point, and
- set a center line, which is a virtual straight line for the first measurement surface, based on the first location data.
A method of modeling a blade of a wind turbine, comprising:
- obtaining photographing data on a first surface of the blade at a plurality of time points;
- modeling the first surface as a virtual straight line for the first surface;
- and
- modeling a second surface using at least one of a parallel translation technique and an orthogonal projection technique based on a virtual straight line for the first surface,
- wherein the virtual straight line for the first surface comprises at least one of a left line, a center line, and a right line for the first surface, and
- wherein the modeling the second surface models the second surface by correcting a position of a preliminary virtual straight line for the second surface generated based on location data on the second surface so as to be parallel to any one of the left line, the center line, and the right line for the first surface or by orthogonally projecting the preliminary virtual straight line for the second surface generated based on the location data on the second surface onto a surface that includes the left line or the right line for the first surface and is perpendicular to the first surface.
