Embodiment Construction
[0023] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.
[0024] The present invention is mainly based on multi-WSVM integration to classify full-waveform LiDAR point clouds. The feature is that the commonly used SVM kernel function is not capable of distinguishing similar features, and the wavelet kernel function is used to enlarge the gap between samples. Sometimes a single classifier If the ideal and stable classification effect cannot be obtained, ensemble learning is used to improve the generalization ability and classification accuracy, and the PSO algorithm is used to optimize the parameters of each WSVM class...
