Trajectory Analysis Datasets

The CVRR Trajectory Analysis Dataset provides data for benchmaking trajectory analysis algorithms. The full dataset contains 4 different scenes - a simulated intersection, a real highway, and an 2 indoor omni directional camera sets. The datasets are intended for unsupervised trajectory-based activity analysis which includes classification, prediction, and abnormality detection. The provided trajectories contain only spatial information (velocity must be inferred). True activity labels are provided as well as full track based abnormality label and frame-by-frame unusual event information.

Description

RawLabeledDescription
CROSS: Simulated four way traffic intersection with various through and turn patterns present. Units are pixels. Full labels are available for training and testing for both offline and online analysis.

19 Activities
I5: Highway trajectories in both direction of I5 outside of UCSD. Trajectories are obtained by a simple visual tracker. Units are pixels. The true cluster labeling considers only the lane. Only trajectory labels are available (no abnormality info).

8 Activities
OMNI1: Trajectories of humans walking through a lab captured using an omni-directional camera. Units are pixels. Natural trajectories collected over 24 hours on a single Saturday without participant knowledge. Full labels available for training and testing for both offline and online analysis.

7 Activities
OMNI2: Trajectories of humans walking through a lab captured using an omni-directional camera. Units are pixels. Choreographed trajectories during a 30 minute collection period.
