The invention discloses a one-dimensional non-uniform gear morphology
point cloud precise registration method, and relates to the field of
data processing. The one-dimensional non-uniform gear morphology
point cloud precise registration method is used for solving the problem that a discrete sequence registration error is large because sample intervals of corresponding points are different when an ICP registration
algorithm is adopted to carry out registration on the corresponding points of an actually-measured gear sequence and a virtual gear sequence. The method comprises the steps that first, quantity registration is carried out on the actually-measured gear sequence and the virtual gear sequence; second,
initial phase registration is carried out on the actually-measured sequence and the virtual gear sequence; third, corresponding-
point registration is carried out on the actually-measured sequence and the virtual gear sequence. The one-dimensional non-uniform gear morphology
point cloud precise registration method is based on the actually-measured gear sequence, regenerates virtual gear sequence with the same sample intervals of the corresponding points as the actually-measured gear sequence, and further improves the accuracy of the gear one-dimensional non-uniform point
cloud data registration. The one-dimensional non-uniform gear morphology point cloud precise registration method can achieve one-dimensional non-uniform gear morphology point cloud precise registration, and is high in registration accuracy, simple to calculate and reliable.
