[0015] S1 one-dimensional range image data preprocessing:
[0016] Calculate the kurtosis matrix K of the one-dimensional range image, find the maximum element max(K) of the kurtosis matrix and its corresponding one-dimensional range image, and count the remaining one-dimensional range image set {x i} and outlier kurtosis set {k i}:
[0017]
[0018] where N is the number of one-dimensional range images, X i is the remaining ith one-dimensional range image sample data, μ i is the sample mean, σ i is the sample standard deviation, E(X i -μ i ) 4 is the fourth-order center-to-center distance of the i-th one-dimensional distance image sample data. if k i If it is not positive, the i-th one-dimensional range image is considered to be an abnormal one-dimensional range image and discarded. The one-dimensional range image corresponding to the largest element of the kurtosis matrix is used as the base image, and the minimum entropy spectrum estimation criterion is used f...
