Ansys collaborated with Sony Semiconductor Solutions to enhance high-fidelity image sensor simulation and camera-based features in next-generation automotive applications, including AV and ADAS. Now, Ansys Speos can seamlessly integrate with Sony’s sensor models to streamline development and validation with more precise modeling.

Generally, automotive image sensors must continuously evolve to deliver safer, higher-functioning ADAS capabilities. To meet this demand, Ansys developed a novel software interface compatible with Sony’s sensor models. Specifically, these are based on the internal architecture of image sensors used in camera systems. Also, the interface enables high-fidelity virtual camera testing in various scenarios and contexts. Accordingly, this reduces the need for ad-hoc physical camera testing and accelerates verification times.

The users of Sony’s image sensors will now have access to end-to-end automotive-grade simulation fidelity for spectral effects, high dynamic range (HDR), and LED light flicker mitigation. Moreover, they can also reproduce image sensor phenomena, such as motion blur and rolling shutter.

The collaboration between Ansys and Sony will provide an automotive-grade, end-to-end spectral simulation pipeline from lens models to sensor models for the ADAS perception system developers. This is according to Kenji Onishi, deputy senior general manager, automotive business division, Sony Semiconductor Solutions Corporation. “Sony has prepared a sensor model based on the internal architecture of the image sensors used in camera systems to achieve automotive-grade fidelity,” said Onishi.

Physical prototyping and validation are time consuming, costly, and do not offer the bandwidth that simulation and virtual testing provides. Specifically, Pairing Ansys simulation with Sony’s sensor models alleviates these challenges through virtual testing. Particularly, this is beneficial for edge-case scenarios, such as when exiting tunnels.

The Ansys and Sony technology collaboration facilitates rapid development and verification of camera features for AV and ADAS applications. This is according to John Lee, vice president and general manager of the electronics, semiconductor, and optics business unit at Ansys. “As a result, the joint workflow yields more robust simulations, greater predictive accuracy, higher-fidelity images. Ultimately, it produces more reliable AV and ADAS applications.”
