Abstract
We leverage the classic compressed sensing concept of the Single Pixel Camera to build an imaging system for objects in scattering media, such as fog. With the DMD and ultra-fast FPGA-based signal sampling as the enabling technologies, we can combine compressed sensing, advanced image reconstruction algorithms and Time-of-Flight detection to achieve video-level frame rates. We discuss the benefits of our approach compared to established techniques in the context of autonomous vehicles in particular, and imaging in harsh conditions in general.
