[0113] Figure 12 A schematic diagram of the aircraft joystick handle model and feature points in Example 1 is shown, Figure 13 A schematic diagram of the characteristic lines of the joystick handle of the aircraft in Example 1 is shown. Figure 12 The circled points in represent the feature points extracted by using the point cloud feature point extraction method of the present invention.
[0114] like Figure 12 As shown, in the characteristic line connection experiment, a smooth special-shaped surface is selected, and the joystick handle of the aircraft is composed of a cylinder, four blind holes and a special-shaped surface. Figure 12 Figure (a) shows the aircraft joystick handle model, the model has a total of 5006 data points, and the threshold coefficient λ=5.0, Figure 12 (b) shows the aircraft joystick handle model and feature points. A total of 619 feature points were extracted to form 10 feature lines. The results are as follows Figure 13 The model and charac...
