PD Replica

Overview

PD Replica by Parallel Domain is a simulation-ready, dynamic world reconstruction service. It turns fleet capture data into high-fidelity replicas with physics-aware worlds, multi-sensor simulation (camera, lidar, radar), semantic segmentation, and HD maps. The PD Pose Engine handles messy real-world data (GPS drift, sparse coverage, misalignment). Automated sim-to-real validation provides quantitative quality reports. Replicas cover corridors up to 3 km long, enabling closed-loop testing of full driving scenarios.
