First, I will show an imaging technique for imaging automotive tires (even in dusty, debris-prone conditions) at high quality. This has created valuable automotive health sensing infrastructure for use in agricultural, mining and passenger vehicles. Second, I will talk about machine learning based super-resolution, learning from expensive sensors to train compact, cheaper sensors to perceive robustly in harsh conditions. I show how this has enabled a firefighting robot to perform search and rescue operations through camera-denied, smoky environments. Finally, I will introduce neural radiance field techniques to generate realistic, synthetic radio frequency data to further bootstrap large data needed to train these large models.
I will conclude the talk with my future vision on how to push towards camera-quality perception from these devices – from both a computational and hardware perspective. Higher fidelity radio frequency perception and communication will unlock creative exploration of applications, seeing through new scattering and occluded media and solving pressing issues.
