    Abstract: Disclosed herein are an apparatus and method for searching for a global minimum of a point cloud registration error. The apparatus includes memory in which at least one program is recorded and a processor for executing the program. The program performs collecting multiple registration results in which the registration error between a source point cloud and a target point cloud is a local minimum as candidates and selecting the registration result in which the registration error between the source point cloud and the target point cloud is a global minimum, among the candidates. Collecting the multiple registration results may comprise repeatedly randomly initializing the source point cloud and the target point cloud and registering the initialized source point cloud to the initialized target point cloud to thereby search for a registration result in which the registration error therebetween is a local minimum.

  • Patent number: 11865211
    Abstract: The present disclosure relates to a nanoparticle complex that is taken into cells to be used for the treatment of diseases, and a method of manufacturing the same using a top-down process. In the top-down process, surfaces of nanoparticles are modified with a lipid-based material having high stability and excellent biocompatibility, thereby improving endocytosis efficiency. A lipid structure having a tube shape is bonded to a portion of the surface of the nanoparticle, so that the nanoparticle complex undergoes endocytosis, directly penetrates a cell membrane, and is effectively taken into spheroid-type tumor cells. The lipid structure is not directly attached to the nanoparticles, lipid-based lipidomes (such as bubbles and liposomes) are bonded to the nanoparticles, and mechanical force is applied thereto to thus crush the lipidomes, so that the lipid structure is formed on the surface of the nanoparticle.
