DRIVE Chauffeur, built on NVIDIA DRIVE AV software, relies on a combination of DNNs to detect and classify scene semantics, such as traffic signs and lights, to chart your path ahead. Specifically, it uses our WaitNet DNN for intersection detection, traffic light detection, and traffic sign detection. The LightNet DNN then classifies traffic light shape (solid versus arrow) and state (color: red, yellow, green), while the SignNet DNN identifies traffic sign type. Collectively, these three DNNs form the core of NVIDIA’s wait conditions perception software, designed to detect traffic conditions in which an AV needs to slow to an intersection and wait before proceeding.
