  • Publication number: 20220275260
    Abstract: The present disclosure provides a surface protective film which is used in a process of fabricating an encapsulation layer for an organic light-emitting diode, and makes it possible to prevent bubbles from being generated in the protective film or the surface smoothness of the protective film from being degraded, due to solvent volatilization from the protective film. Specifically, the present disclosure provides a surface protective film including an adhesive layer provided on one surface of a substrate layer, wherein the adhesive layer includes a cured product of an adhesive composition including: a urethane-based resin having a photoreactive group at the end or side chain thereof; a monofunctional (meth)acrylate monomer; a crosslinking agent having two or more photoreactive groups at the end thereof; a photoinitiator; and a photoreactive siloxane additive, the adhesive composition being solvent-free.

  • Publication number: 20220254095
    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: 11354854
    Abstract: Disclosed herein a method of removing a point cloud outlier and an apparatus implementing the method. The method includes: arranging a point cloud obtained from a laser scanner along at least a first direction; selecting, neighboring first-axis points, between which a separation degree satisfies an inspection start threshold condition, as a first leading-side representative point and a first trailing-side representative point; selecting a first leading-side outlier candidate and a first trailing-side outlier candidate based on a first leading-side separation degree and a first trailing-side separation degree; and determining the first leading-side outlier candidate and the first trailing-side outlier candidate as a first outlier point, when the number of the outlier candidates satisfies an allowable threshold condition.
