The FineView Dataset: A 3D Scanned Multi-View Object Dataset of Fine-Grained Category Instances

In the past decade state-of-the-art deep learning mod-els have shown impressive performance in many computer vision tasks by learning from large and diverse image datasets. Most of these datasets consist of web-scraped image collections. This approach, however, makes it very challenging to obtain desirable data such as multiple views of the same object, 3D geometric information, or camera parameters for a large-scale image dataset. In this paper, we propose a 3D-scanned multi-view 2D image dataset of fine-grained category instances with accurate camera cali-bration parameters. We describe our bi-directional, multi-camera and 3D scanning system and the data collection pipeline. Our target objects are relatively small, highly-detailed fine-grained category instances, such as insects. We present this dataset as a contribution to fine-grained vi-sual categorization, 3D representation learning, and for use in other computer vision tasks.
