[0084] (1) Selection of data sets
[0085] In order to verify the performance of the semantic split network model of the present embodiment, the three-dimensional point cloud data of the present embodiment is derived from a large-scale Semantickitti data set and a small-scale SemanticPoss dataset. The SemantickItti dataset is built in a manner that provides a dense point semantic labeling for a 360-degree scanned Kitti Odometry Benchmark. This data set contains 21 sequences of 43,000 scan data. The 21000 scan data of the No. 00 and 10 sequence is used for training, and the 08 sequence is used to verify, and the 11 to 21 sequence is used to test. SemanticPoss data is a small-scale dataset created by Peking University, which contains 2988 complex scenes with high quality dynamic goals. It follows the same data format specification as Semantickitti. This data set has 6 parts, where 2nd and third parts are used for testing, and the remainder is used for training.
