Multi-view Visual Question Answering Dataset for Real Environment Applications

Abstract

In this paper, we propose a novel large scale Visual Question Answering (VQA) dataset, which aims at real environment applications. Existing VQA datasets either require high constructing labor costs or have only limited power for evaluating complicated scene understanding ability involving in VQA tasks. Moreover, most VQA datasets do not tackle scenes containing object occlusion, which could be crucial for real-world applications. In this work, we propose a synthetic multi-view VQA dataset along with a dataset generation process. We build our dataset from three real object model datasets. Each scene is observed from multiple virtual cameras, which often requires a multi-view scene understanding. Our dataset requires relatively low labor cost and in the meantime, have highly complicated visual information. In addition, our dataset can be further adapted to users’ requirements by extending the dataset setup. We evaluated two previous multi-view VQA methods on our datasets. The results show that both 3D understanding and appearance understanding is crucial to achieving high performance in our dataset, and there is still room for future methods to improve. Our dataset provides a possible way for bridging the VQA methods aiming at CG dataset with real-world applications, such as robot picking tasks.
