Point cloud registration is important for the processing of 3D model reconstruction, but with the challenge of low registration accuracy. In order to overcome this obstacle, this paper proposed a dual attention mechanism registration (DAMR) method for the point cloud registration. Firstly, the dual attention mechanism is utilized to extract key point features with different dimensions via assigning weights to the input point clouds. Secondly, the matching parameters are obtained by estimating the position correspondence between feature points and gaussian mixture model. Finally, the parameter unit blocks of two models are applied to recover the optimal transformation by matching parameters. In order to test the performance of our method, four groups of datasets include public data models and cultural relic models are adopted, respectively. Compared with traditional methods, our method has shown better performance to effectively ensured the registration accuracy of 3D point cloud models.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
