In order to meet the demand of aeronautical component remanufacturing design, it is proposed to use the high precision laser tracker to control the wing trailing edge structural components and obtain the point cloud data by means of industrial photographic scanning measurements. Finally, by using the obtained point cloud data to make the reverse modeling task, the results of surveying and modeling ar e evaluated by Geomagic and Control. The experimental results show that the method has high accuracy, fast efficiency and satisfies the remanufacturing design requirements, which provides a new measurement idea and method for reverse modeling technology.
