What is it about?
This study provides a novel framework for 3D point cloud instance segmentation, which uses Transformer and contrained spatial information from bounding boxes to improve object recognition in 3D space. Research on 3D instance segmentation is widely applied in practice in autonomous driving, VR/AR, indoor scanning, construction,...

Why is it important?
This study porpose a twin-attention mechanism for superpoints with diverse scales, which helps accurately identify objects with different sizes. In addition, it also uses boundary constraints to refine objects, thereby making recognition more accurate as well as eliminating noise in complex 3D space.
Perspectives
A 3D object recognition model will be an important part of autonomous vehicle technology, VR/AR/XR, construction, medicine,... We improve the model performance by using a dual attention mechanism that captures multiple scales of different objects in space. And locates objects more accurately with spatial constraints of bounding boxes.
