Abstract: The present disclosure may provide a method and apparatus for registrating point cloud data sets. The method for registrating point cloud data sets may include extracting at least one plane from a first point cloud data set and a second point cloud data set respectively which are to be registered, performing an initial registration based on an identical plane among the extracted at least one plane, and performing optimization for a size, a location and a direction of the first point cloud data set and the second point cloud data set, and the first point cloud data set and the second point cloud data set may include data obtained through sensors placed in different locations.

Abstract: A method and a device for transmitting and obtaining dynamic 3-dimensional (3D) avatar data are provided. The method for transmitting dynamic 3D avatar data may include generating a plurality of data elements configuring the dynamic 3D avatar data; performing first encoding and transmission for a first data element of the plurality of data elements; and performing second encoding and transmission for a second data element of the plurality of data elements. Each of at least one of the first data element or the second data element may be divided into a plurality of sub-data elements.

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.
