To address the issues of high computational cost and complex network models in point cloud classification and segmentation methods, a point cloud classification and segmentation algorithm based on lightweight networks and weighted Random Forest (RF) was proposed. The algorithm achieved efficient classification and segmentation in a hierarchical manner. Firstly, to address the issues of multiple layers and complex computation in traditional neural networks, a lightweight neural network was constructed to extract point cloud features such as global shape, inter-regional relationships, curvature, normal vector, and color, thereby achieving rapid rough classification and segmentation of point clouds. Then, to address data imbalance, an adaptive classification and segmentation strategy was designed. By introducing a weighted RF and combining inconsistency-measurement screening with dynamic-weighting optimization mechanisms, fine classification and segmentation of point clouds were achieved. The algorithm conducted classification experiments on the ModelNet40 dataset and segmentation experiments on the Semantic3D dataset and outdoor-scene point-cloud data. The results showed that compared with Local Geo-Transformer, PointNeXt, and FastPointNet++, classification and segmentation accuracy increased by approximately 1.9%, 1.6%, and 1.7%, respectively, while classification and segmentation time was reduced by approximately 40%, 30%, and 20%, respectively. Thus, the proposed point-cloud classification and segmentation algorithm based on lightweight networks and weighted RF can effectively reduce the training time of the model and improve the efficiency of classification and segmentation while maintaining high accuracy, making it an effective point cloud classification and segmentation algorithm.

针对点云分类分割方法中存在的高计算开销、复杂网络模型等问题,提出一种基于轻量级网络和加权随机森林(RF)的点云分类分割算法。该算法采用层次化的方式实现高效分类分割,首先针对传统神经网络层数多、计算复杂等问题,构造轻量级神经网络,并利用其提取点云的全局形状、区域间关系、曲率、法向量和颜色等特征,实现点云的快速粗分类分割;然后针对数据不平衡的问题,设计自适应分类分割策略,并引入加权RF,结合不一致度量筛选与动态加权优化机制,以实现点云精分类分割。在ModelNet40数据集上进行分类实验,在Semantic3D数据集和室外场景点云数据上进行了分割实验,结果表明,相比Local Geo-Transformer,PointNeXt和FastPointNet++等算法,该算法的分类分割精度分别提高了约1.9%,1.6%和1.7%,分类分割时间分别降低了约40%,30%和20%。由此可见,基于轻量级网络和加权RF的点云分类分割算法在保持较高分类分割精度的同时,可以有效缩短模型的训练时间,提高分类分割效率,是一种有效的点云分类分割算法。
