Abstract
Indoor understanding is currently a topic that is widely studied in the field of machine learning. Furniture is the most common object in indoor scenes, just as various vehicles are most commonly seen in street scenes. Any object is made up of a combination of functional components. Functional component dismantling and reassembly is an important development for industrial manufacturing to improve efficiency and reduce costs. In the context of understanding indoor scenes, we focus on building a dataset that uses real-world furniture images as part labels. Building a large-scale furniture dataset is very challenging, first of all, the existing dataset has too few real images of furniture, mostly 3D model images, but the diversity of furniture in the real world far exceeds that of 3D models, and real images help improve the calculation speed of model training. Most of the published furniture data is poorly aligned with the annotation data, and even fewer materials perform component segmentation labeling using real furniture images. MontageNet has become a rich resource for part-level 3D shape analysis, semantic understanding, instance segmentation and 3D reconstruction, and other research. Our accompanying empirical studies provide an in-depth analysis of dataset characteristics and performance evaluation of several state-of-the-art methods against our benchmarks.
