SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Measures and interprets path-tracking performance for navigation systems, enabling quantitative evaluation of cross-track error, heading alignment, and path efficiency.

Core Features & Use Cases

Compute cross-track error, heading error, and path length ratio from /odom and /plan data.
Provide an analysis script to output mean, max, and statistics for these metrics, plus guidance for tuning controllers.
Use in offline troubleshooting, patrol planning, and continuous monitoring to detect drift or degradation.

Quick Start

Run the path-tracking-metrics analysis script on a rosbag containing /odom and /plan data to output the metrics.

FAQPage Schema

How do I calculate cross-track error and heading error from ROS 2 bag data?▼

To calculate cross-track error and heading error from ROS 2 bag data, run an offline analysis script on rosbag files containing /odom and /plan data streams to quantify navigation path-tracking fidelity.

What metrics are needed to evaluate ROS 2 navigation path-tracking quality?▼

Evaluating ROS 2 navigation path-tracking quality requires metrics like cross-track error, heading error, path length ratio, and velocity statistics computed from odometry, plan, local_plan, cmd_vel, and tf data streams.

Can I use path-tracking analysis scripts for outdoor ROS 2 patrols and simulated scenarios?▼

Yes, path-tracking analysis scripts apply to offline analysis for indoor and outdoor ROS 2 patrols, vehicle datasets, and simulated scenarios where path following is critical.

How do I troubleshoot ROS 2 navigation drift using rosbag2 recordings?▼

To troubleshoot ROS 2 navigation drift using rosbag2, analyze recorded odometry and plan data to compute mean, max, and statistics for tracking metrics, detecting degradation and guiding controller tuning.

Do I need local_plan and cmd_vel topics to measure path length ratio in ROS 2?▼

Yes, measuring path length ratio and velocity statistics requires local_plan and cmd_vel topics alongside odometry, plan, and tf data streams recorded in your ROS 2 bag.
