Abstract: Highlights•A new network MHIBS-Net for semantic segmentation of indoor building structure point clouds.•Normal vector information of point clouds is added and a relative position encoding unit is designed to enhance feature expression and description.•A multilevel hierarchy feature decoding method to address the shortcomings of traditional feature decoding process.•Local and global multiscale hierarchical features for highly accurate semantic segmentation.
