Egocentric vision has a wide range of applications for human-centric activity recognition. However, the use of the egocentric fisheye camera allows wide angle coverage but image distortion is introduced along with strong human body self-occlusion, which can impose significant challenges in data processing and model reconstruction. Unlike previous work only leveraging synthetic data for model training, this paper first presents a new real-world EgoCentric Human Action (ECHA) dataset. By using the self-supervised learning under multi-view constraints, we propose a simple yet effective framework, namely EgoFish3D, for egocentric 3D pose estimation from a single image in different real-world scenarios.
