Record Analyzer Tool

Offline Record files analysis

Functions

Record analyzer is a tool for analyzing the .record file created by cyber_recorder tool.

It currently supports statistical analysis for

• Control module latency
• Planning module latency
• End to end system latency

And distribution analysis for

• Control error code
• Control error message
• Planning trajectory type
• Planning estop
• Planning error code
• Planning error message

Usage

python main.py -f record_file

Simulation Score API

Functions

This API is used for simulation to grade planning trajectories.

It currently supports following scores:

• frechet_dist: calculate the frechet_dist for two consecutive planning trajectories
• hard_brake_cycle_num: number of planning cycles that acceleration is less than -2.0 m/s^2
• overall_score: aggregated score for above metrics

Usage

python main.py -f record_file -s
