Aircraft Wing Deformation Measurement Method Based on Three-dimensional Speckle Image

Wing deformation has a direct impact on aircraft performance and personnel safety, so it is of great significance to test the deformation law. Traditional methods of wing deformation measurement generally have some shortcomings, such as fewer measuring points and poor real-time performance. In recent years, the developed three-dimensional speckle correlation vision measurement technology has many advantages, such as high accuracy, strong real-time performance, small environmental impact and non-contact full-field measurement. It can overcome the traditional methods in wing deformation measurement. The deficiency of law. Therefore, the method of wing deformation measurement based on three-dimensional speckle correlation method is studied in this paper.
