A Storage-Efficient Feature for 3D Concrete Defect Segmentation to Replace Normal Vector
PositiveArtificial Intelligence
- A new study has introduced a storage-efficient feature for 3D concrete defect segmentation, replacing traditional normal vectors with a single-dimensional feature called relative angle. This feature is calculated as the angle between the normal vector of a point and the average normal vector of its parent point cloud, allowing for effective defect characterization while significantly reducing data storage requirements.
- The implementation of relative angle in models trained with PointNet++ has shown comparable performance to those using normal vectors, achieving a notable 27.6% reduction in storage and 83% compression of input channels. This advancement is crucial for industries reliant on precise 3D data analysis, as it enhances efficiency without compromising accuracy.
- This development reflects a broader trend in artificial intelligence and computer vision, where researchers are increasingly focused on optimizing data representation and processing. The introduction of innovative features like relative angle aligns with ongoing efforts to improve the efficiency of machine learning models, particularly in applications involving large-scale 3D data, such as construction, robotics, and autonomous systems.
