Trajectory Annotation & Reconstruction
Research Platform
A two-phase research platform for pedestrian trajectory annotation and reconstruction analysis
Trajectory Annotation
Place strategic knots on pedestrian trajectories to mark significant movement points
Real-time Annotation
Annotate pedestrian trajectories with precision using our intuitive tools
Pattern Analysis
Compare and analyze trajectory patterns across different scenarios
Knot Placement
Place strategic knots to mark significant trajectory points
Trajectory Reconstruction
Reconstruct trajectories by placing anchor points and drawing curves through them
Anchor Point Selection
Select anchor points from Phase 1 annotations to guide your reconstruction
Curve Drawing
Draw smooth curves through anchor points to reconstruct the trajectory path
Trajectory Validation
Help validate if knot placements capture essential trajectory information
Phase 2 Demo Coming Soon
Research Purpose
A two-phase approach to understanding trajectory perception and reconstruction
The Challenge
Autonomous vehicle safety relies on testing against diverse pedestrian behaviors. Current methods miss subtle variations and lack benchmarks for evaluating trajectory quality.
Phase 1: Annotation
Gather human annotations by placing knots on trajectories, capturing how people naturally perceive significant movement points and patterns.
Phase 2: Reconstruction
Validate annotation quality by reconstructing trajectories from anchor points, revealing if knot placements capture essential trajectory information.
The Impact
Comparing reconstructed trajectories with originals helps improve annotation guidelines and simulation accuracy for autonomous vehicle safety.
