Bonn Activity Maps: Dataset Description
This dataset addresses the need for comprehensive data in multi-person activity analysis, but it is incremental as it builds on existing datasets by combining elements like 3D scenes and multi-person tracking.
The authors introduced Bonn Activity Maps, a large-scale dataset for human tracking, activity recognition, and anticipation of multiple persons, comprising four scenes with synchronized cameras, 3D models, motion trajectories, and activity annotations, which they used to generate activity likelihoods on 3D models.
The key prerequisite for accessing the huge potential of current machine learning techniques is the availability of large databases that capture the complex relations of interest. Previous datasets are focused on either 3D scene representations with semantic information, tracking of multiple persons and recognition of their actions, or activity recognition of a single person in captured 3D environments. We present Bonn Activity Maps, a large-scale dataset for human tracking, activity recognition and anticipation of multiple persons. Our dataset comprises four different scenes that have been recorded by time-synchronized cameras each only capturing the scene partially, the reconstructed 3D models with semantic annotations, motion trajectories for individual people including 3D human poses as well as human activity annotations. We utilize the annotations to generate activity likelihoods on the 3D models called activity maps.
