Nowadays, with the development of 3D filtering information processing by data algorithms, people have deeply studied processing. A series issues were found in research process. Moreover, current on point cloud use lidar is not comprehensive. Its focuses noise reduction and block segmentation cloud-filtered data. Based above background, this paper analyzes bilateral characteristics detail. It im...

In this paper, a new dynamic self-adaptive multi-objective particle swarm optimization (DSAMOPSO) method is proposed to solve binary-state multi-objective reliability redundancy allocation problems (MORAPs). A combination of penalty function and modification strategies is used to handle the constraints in the MORAPs. A dynamic self-adaptive penalty function strategy is utilized to handle the co...
