Parallel Domain vs StreamGen

Parallel Domain turns drive or flight logs into simulation-ready scenes for validating autonomous systems. PD Replica reconstructs static environments and moving actors, allowing users to resimulate, modify, remove, or recompose actors and actions. It provides physics-aware collision layers, semantic and instance segmentation labels, and an annotated HD map containing lane geometry, traffic rules, and routing information. Automated reports measure geometric fidelity, appearance fidelity, and annotation accuracy against source data. PD Sim configures deterministic scenarios and simulates camera, lidar, and radar, including multi-sensor rigs. Scenario parameters can vary, tests can run in parallel, and APIs support open-loop or closed-loop testing with CI/CD pipelines. A Python SDK enables programmatic control and closed-loop autonomy-stack connections. Drive or flight logs are inputs; lidar can improve fidelity but is not required. The company says continuous corridors up to 3 km can be reconstructed. Pricing is on request, and prospective customers are invited to book a demo. Industries listed include automotive, trucking, drones, robotics, agriculture, and defense.
