This invention describes a system for autonomous vehicles that uses machine learning to understand its surroundings by combining information from various sensors over time. It first processes images from different sensors into a "fused feature map" for a specific moment. Then, it combines this current map with previously generated fused maps, which are adjusted for temporal changes, to create a comprehensive understanding of the environment. This combined, time-aware information helps the vehicle make decisions.
Why it matters: Filed before the widespread adoption of advanced multi-modal foundation models. The ability of machine learning models to intrinsically fuse diverse sensor data and perform sophisticated temporal transformations has significantly matured since 2023.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
