Estimating the 6D pose of rigid objects is a critical upstream task in many robotics applications. Most existing methods rely on RGB or RGB-D sensing modalities, which suffer from limitations under challenging lighting conditions and high-speed motion. In contrast, event-based cameras offer unique advantages such as high temporal resolution and high dynamic range, making them well-suited for such scenarios. However, current event-based pose estimation methods are typically optimization-based, designed for relatively simple objects, and require hand-crafted parameters. In this work, we introduce the first learning-based approach for 6D object pose estimation using event cameras, employing an Augmented Event Encoder (AEE) trained entirely only on synthetic data and validated on the E-POSE dataset. Our model leverages an augmented autoencoder with domain randomization to map synthetic templates into a latent space, enabling accurate matching with real event query images. The method demonstrates robust performance across various scenarios, including changes in illumination and camera speeds, and achieves strong results on the ADD-S (Rotation) metric.
