Format Advantages Disadvantages
Multi-View (RGB-D)
  • Render 2.5D images from real views
  • Uses CNN for 3D analysis
  • Self-occlusion
  • Large view computation
  • Not sufficient for complete geometry
Voxels
  • Describes spatial topological relationship
  • Huge memory requirement
  • Large amount of invalid 3D data generated
Point Cloud (X,Y,Z,rgbC)
  • Represents accurate characteristics
  • End-to-end information transmission
  • Directly exportable from 3D models
  • Disordered and unstructured, difficult for direct deep learning without specific models like PointNet
600+ Original Data Samples Enhanced

Data augmentation using 'provider.py' effectively solves insufficient original data, improving generalization ability with random rotation, scale scaling, and position migration.

Case Study: Training Convergence Success

Scenario: PointNet++ training for subway station spatial segmentation achieved rapid convergence.

Challenge: Ensuring high data quality and model robustness.

Solution: 137 rounds of training led to a peak accuracy of 0.765708, with average loss stabilizing at 0.428847. This demonstrates excellent training effect.

Results: The model quickly converged, with both training mean loss and accuracy curves stabilizing, indicating high data quality and robust learning. Complex stations like sample 1 (exchange station with multiple lines) showed high prediction quality.

0.80+ Eval Avg Class Accuracy Achieved

The model demonstrated strong predictive capabilities, with Eval Avg Class Accuracy exceeding 80% and overall Eval Accuracy at 75% for the test set.

Space Type IoU Performance Reasoning
Entrance & Exit, Track Area Higher
  • Relatively stable spatial form and position, easier for model to learn.
Paid Area, Non-Paid Area, Platform Floor Middle
  • Relatively stable locations but varied morphology, requires more training.
Barrier-free Elevator, Escalator, Stair Area Lowest
  • Complex spatial intersections and characteristics, requiring further research.

Case Study: Model's Self-Optimization Capability

Scenario: During prediction, the model demonstrated the ability to optimize spatial layouts beyond just replication.

Challenge: Moving from mere recognition to intelligent design adaptation.

Solution: Prediction results for Sample 2 and Sample 4 showed enlarged traffic spaces compared to ground truth, indicating the model's self-learning and optimization capability based on extensive training data.

Results: The model can reasonably optimize spaces, reflecting a strong self-learning ability rather than just matching, demonstrating its potential for architectural scheme generation.
