The great idea of sensor fusion is to take the inputs of different sensors and sensor types and use the combined information to perceive the environment more accurately. That results in e better and safer decisions than independent systems could do. Radar might not have the resolution of light-based sensors, but it is great for measuring distances and piercing through rain, show and fog. These conditions or the absence of light do not work well for a camera, but it can see color (think street signs and road markings) and has a great resolution. We have one megapixel image sensors on the street today. In the next few years the trend will be two and even four megapixels.
