PeTrack#
PeTrack (Pedestrian Tracking) is a software to extract the trajectories of pedestrians from videos. It encompasses the entire workflow from calibration, recognition, tracking and manual correction.
The software supports various types of data input (image sequences, videos, stereo videos) and can even handle visibly distorted videos correctly. PeTrack utilizes different kinds of markers (e.g. with height information, head direction, individual code). When using a marker with an individual code trajectories from PeTrack can be connected to other data sources, such as questionnaires.
An executable of PeTrack is available here.
