Abstract: A point cloud descriptor matching method based on complex vector angle characteristics is provided. Dimensionality reduction is performed on an original complex descriptor to obtain a complex descriptor derivative. Rapid retrieval and filtering are performed by using the complex descriptor derivative in a database to obtain filtered complex descriptors. Similarity comparison is performed on the filtered complex descriptors by utilizing multiple angle characteristics of complex vectors to obtain a complex descriptor with a preset accuracy among the filtered complex descriptors. Possible complex descriptors are rapidly retrieved and filtered out by virtue of the constructed derivative respectively, and the accurate matching of the same position is ultimately completed by utilizing the multiple angle characteristics of complex vectors. A point cloud descriptor matching method based on complex vector angle characteristics is also provided.
