rmographic flow visualization and optical 3D geometry measurement

Topic

Have you ever wondered why wind turbines sometimes don't turn even though it's windy? The answer could depend on the flow conditions at the rotor blades. This flow can be made visible continuously using thermography from a great distance and without stopping the wind turbine. For this purpose, an innovative synchronous measurement principle (Figure 1) was developed at our institute.

In order to assign the detectable flow phenomena to rotor blade areas, the rotor blade geometry is to be recorded in parallel with a laser scanner from the ground (>100 m). By merging both data sets, the 2D thermographic images are to be applied to the 3D rotor blade surface.

Possible Tasks

- Parallel laser scans and thermography on wind turbines

- Conducting measurement campaigns in the field

- Evaluating laser data

Requirements:

- Knowledge of Python programming

- Experience in image processing

- Basic understanding of coordinate transformations
