- W4385784890 abstract "As one of the main components of the urban interior, buildings play a pivotal role in the construction of smart cities. In order to segment the structural characteristics contained in building facades more accurately and efficiently and intelligently, this paper constructs a small building facade dataset based on on-board LiDAR point clouds, and improves it based on the original PointNet++ network by adding a multi-headed attention mechanism module in model feature extraction; in model training, an extraction function is introduced after the training function for unlabelled In terms of model training, an extraction function is introduced after the training function to extract features from the unlabelled building façade data, and the extraction results are finally given labels and saved to the training data set, so as to achieve the effect of enhancing the training sample data, and by improving the model structure and model training method, the effective extraction of building façade features is achieved. The final accuracy of the proposed method is 88.2% and the average intersection-to-merge ratio (mIoU) is 77.1%, which is 1% and 3.3% higher than the original PointNet++ network respectively." @default.
