Abstract

Nowadays, one of the major challenges global society is facing is population aging, which involves an increment of the medical expenses. Since falls are the major cause of injuries for elderly people, the need of a low-cost falling detector has increased rapidly over the years. In this context, we propose a fall-detection system based on 3D Convolutional Neural Networks (3D-CNN). Due to the fact that the system only uses depth information obtained by a RGB-D sensor placed in a overhead position to avoid occlusions, it results in a less invasive and intrusive fall-detection method for users than systems based on wearables. In addition, depth information preserves the privacy of people since they cannot be identified from this information. The 3D-CNN obtains spatial and temporal features from depth data, which allows to classify users’ actions and detect when a fall appears. Since there are no other available datasets for action recognition using only depth data from a top-view camera, the authors have recorded and labeled the GOTPD3, that has been made available to the scientific community. Thus, training and evaluation of the network has been carried out within the GOTPD3 dataset, and the achieved results validate the proposal.
