Abstract: The present disclosure discloses a method for multi-view point cloud registration for a whole aircraft based on a spherical harmonic feature (SHF). Gaussian sphere projection is mainly performed on a local point cloud. An SHF of each point is obtained by using a spherical harmonic transform technology. A constraint correspondence between feature points is found based on an SHF of each point in the point cloud. Multi-view point cloud data registration is performed according to an optimization graph method under a constraint of the SHF. A key of multi-view point cloud registration is to search for feature constraint relationships between different observation stations and perform non-linear solution based on these relationships, so as to obtain a pose parameter of a point cloud in each viewing angle.
