  A large field-of-view fisheye camera allows for capturing a large area with
minimal numbers of cameras when they are mounted on a high position facing
downwards. This top-view omnidirectional setup greatly reduces the work and
cost for deployment compared to traditional solutions with multiple perspective
cameras. In recent years, deep learning has been widely employed for vision
related tasks, including for such omnidirectional settings. In this survey, we
look at the application of deep learning in combination with omnidirectional
top-view cameras, including the available datasets, human and object detection,
human pose estimation, activity recognition and other miscellaneous
applications.
