  • Three-dimensional measurement method and system for key morphological feature on aircraft surface, and method for using system
    Patent number: 12586227
    Abstract: Disclosed are a three-dimensional measurement method for the key morphological features on an aircraft surface, a three-dimensional measurement system for the key morphological features on the aircraft surface, and a method for using the three-dimensional measurement system. In this method, the distribution characteristics of point clouds are fully utilized, and an angle is formed between a direction vector of the measurement point and a seam direction, which ensures that the point clouds can gradually approach the actual edge of the seam, and eliminates the impact of randomness. The point nearest to the seam in the point clouds on both sides of the seam is selected as the nearest point, which overcomes the limitation of the density of the point cloud, so that the distance between the selected nearest point and the actual edge of the seam is greatly reduced.
