Embodiment 1
[0084] (1) Selection of data set
[0085] In order to verify the performance of the semantic segmentation network model of this embodiment, the 3D point cloud data of this embodiment comes from a large-scale SemanticKITTI dataset and a small-scale SemanticPOSS dataset. The SemanticKITTI dataset is constructed by providing dense point semantic annotations for the full 360-degree scanned KITTI Odometry Benchmark. This dataset contains a total of 43,000 scans from 21 sequences. Among them, the 21000 scan data of the 00th to 10th sequences are used for training, the 08th sequence is used for verification, and the 11th to 21st sequences are used for testing. The SemanticPOSS data is a small-scale dataset created by Peking University, which contains 2988 complex scenes with high-quality dynamic objects. It follows the same data format specification as SemanticKITTI. There are 6 parts in this dataset, the 2nd and 3rd parts are used for testing, and the rest are used for training. ...
