Abstract

In this paper, we study the representation of the shape and pose of objects using their keypoints. We propose an end-to-end method that simultaneously detects 2D keypoints from an image and lifts them to 3D. The proposed method learns both 2D detection and 3D lifting only from 2D keypoint annotations. In addition to being end-to-end from images to 3D keypoints, our method also handles objects from multiple categories using a single neural network. We use a Transformer-based architecture to detect the keypoints, as well as to summarize the visual context of the image. This visual context information is used while lifting the keypoints to 3D, to allow context-based reasoning for better performance. Our method can handle occlusions as well as a wide variety of object classes. Our experiments on three benchmarks show that our method performs better than the state-of-the-art.
