Re-simulate and analyze AV software issues discovered in field testing

Logstream allows teams to reproduce realistic situations using drive data. Test new versions of your AV stack against existing logs. Generate scenarios from logs to build robust test suites.

Reproduce AV software behavior from events of interest 

Re-run interesting scenarios encountered in the field to verify and improve your system’s performance on past events.

Determine what would have happened if the operator had not intervened through automatic re-simulation
Manually review and confirm issues in a web-based visualizer and share with your team
Run a batch of re-simulations programmatically; add re-simulation tests to continuous integration

Find root causes of bugs and fix stack issues

Analyze inputs, outputs, and powerful metrics to deeply understand stack behavior. Ensure software updates address events of interest found in field testing.

Add, remove, and modify actor behavior to test how motion planning performs in related scenarios
Analyze perception and localization performance using metrics based on ground truth data
Explore how tuning software parameters changes performance

Ensure software updates resolve issues found in the field

Test new versions of your systems against recorded logs to make sure they can safely navigate issues found in field testing.

Re-simulate drive logs with the improved stack to compare with previous behavior
Automatically find failing tests using comprehensive pass/fail metrics
Scalably create comprehensive test suites by augmenting drive logs with synthetic data
