Ansys AVxcelerate Sensors — High-Fidelity Physics-Based Sensor Simulation

Ansys AVxcelerate Sensors  — Deterministic Sensor Validation for ADAS & AV

Ansys AVxcelerate Sensors is a high-performance simulation solution dedicated to the physics-based modeling of Lidar, Radar, Camera, and Ultrasonic sensors. It provides the high-fidelity raw data required to train, test, and validate autonomous driving perception algorithms and sensor fusion stacks in a virtual environment.

• Physics-Based Raw Data Generation: Generate deterministic raw sensor outputs, including GPU-accelerated Radar signal processing and high-fidelity Lidar point clouds with accurate material reflectivity.
• Environmental Realism: Simulate complex multispectral light transport and wave propagation, accounting for weather effects like rain, fog, and snow on sensor performance.
• Ground Truth Extraction: Automatically generate pixel-perfect semantic segmentation, instance labeling, and depth maps for automated training of machine learning models.

Technical Performance & Sensor Specifics

• Real-Time GPU Ray Tracing: Utilize advanced ray tracing for Camera and Lidar to capture secondary reflections, lens distortion, and motion blur at high frame rates.
• Advanced Radar Physics: Model multi-bounce reflections, Doppler shifts, and interference from dielectric surfaces, enabling precise validation of Radar perception in dense urban scenes.
• Sensor-Specific Degradation: Account for sensor-level artifacts such as rolling shutter effects, thermal noise, and lens soiling to test the robustness of the AV stack.

Why Engineers Choose AVxcelerate Sensors?

AVxcelerate Sensors bridges the "sim-to-reality" gap by moving beyond simple object-list simulation. By providing raw data injection, it allows engineers to validate the actual signal processing chain of the sensor hardware before physical deployment.

Integration & Scalability

• HIL & SIL Hardware Injection: Supports low-latency RDMA and CSI/GMSL data injection into smart sensor ECUs and high-speed perception hardware.
• Standardized Connectivity: Fully compatible with ASAM OSI (Open Simulation Interface) for standardized data exchange between sensors and driving simulators.
• Cloud & Parallel Execution: Scale sensor simulation across multiple GPUs or cloud nodes to accelerate massive scenario-based NCAP safety testing.

Modular Configuration & Licensing

Ansys AVxcelerate Sensors is available as a standalone module or as part of the complete AVxcelerate Autonomy suite. Flexible licensing options support R&D, enterprise production, and academic research. Contact our sensor specialists for a technical deep-dive.

Frequently Asked Questions

What is Ansys AVxcelerate Sensors?

Ansys AVxcelerate Sensors is a physics-based simulation module generating high-fidelity raw sensor data for Lidar (point cloud), Radar (raw waveform), Camera (photorealistic image), and Ultrasonic sensors enabling ADAS and AV perception teams to validate algorithms in HIL and SIL environments before physical sensor testing.

What sensor types does Ansys AVxcelerate Sensors simulate?

AVxcelerate Sensors simulates Lidar, Radar, Camera, and Ultrasonic sensors with physics-accurate models that include real-world environmental effects such as rain, fog, dust, and direct glare enabling edge-case perception testing that would be difficult or dangerous to replicate physically.

What is the difference between AVxcelerate Sensors and the full AVxcelerate suite?

AVxcelerate Sensors is a focused module for physics-based raw sensor data generation. The full suite adds the Autonomy module (closed-loop AV stack validation) and the Headlamp module (automotive lighting and Adaptive Driving Beam simulation) for a complete virtual validation environment.
