with the development of adas and automatic driving, sensor fusion has become absolutely necessary. especially the fusion of microwave radar and camera has not only enhanced the precision and accuracy of the target detection, but also reduced the false warning rate. in this way, it is able to greatly enhance the practicability of the fcw (forward collusion warning), aeb (automatic emergency braking) and acc (adaptive cruise control) as well as other applications.
in the evolution from adas to automatic driving, the overlapping and fusion among several sensors contribute to guarantee the safety of system performance and functions. different sensors have different advantages and disadvantages. currently, not yet a kind of sensor could apply to the entire using environment. so only through the fusion of sensors, can the "robustness" or diversification of functions be more appropriately realized.
