| description | The invention provides a method and system for measuring the rotation angle of an aircraft. The method comprises: attaching a coded mark point paster on a to-be-measured aircraft control plane; calibrating a collection device; collecting an image of a coded mark point of the coded mark point paster by using a calibrated collection device and reconstructing a three-dimensional point cloud model ofthe coded mark point, and calculating a rotation angle of the aircraft control plane; respectively collecting images of the coded mark point of the coded mark point paster at a starting point and an end point position after rotation and reconstructing three-dimensional point cloud models respectively, and establishing a target coordinate system by combining the two three-dimensional point cloud models with the rotation shaft; and in the target coordinate system, calculating included angles between all same coded mark points in the three-dimensional point cloud model at the starting point and the three-dimensional poin |
