The rapid proliferation of ADAS systems in automobiles is a prime example of embedded vision technology's potential to transform the way we interact with products. ADAS systems take driving responsibilities away from the driver, bringing us one step closer to fully autonomous vehicles.

Some ADAS systems rely on data generated by multiple sensors located throughout the vehicle, but in recent years camera-based ADAS systems are gaining popularity. It's possible that camera-based systems may be the sole approach to ADAS in the future because of their potential to handle even more advanced ADAS functions than are currently possible.

Advances in embedded vision technology, including higher frame rate cameras and more powerful processors at steadily decreasing costs, have been the primary enablers of ADAS features becoming so commonplace in automobiles.

ADAS features in automobiles include interior-facing cameras for monitoring driver drowsiness, distraction, emotional state or for gesture control of vehicle's infotainment system. Forward-facing cameras can assist with lane departure warnings and collision avoidance. Rear-facing cameras contribute to hands-free parallel parking capabilities.

The number of cameras in every car is increasing, and so are the potential ADAS features they can perform. New ADAS systems hope to perform road sign monitoring, adaptive cruise control and even face recognition. Ultimately, the goal of ADAS systems is to enable a fully autonomous vehicle capable of navigating even in unknown territories without compromising safety.

ADAS features are quickly becoming a standard component in automobiles across the world. By sharing certain driving responsibilities, ADAS systems help improve overall driving safety and even enhance the value of the vehicles they're in.

Embedded vision technology and its increasing capabilities and decreasing costs is a major reason why ADAS features have gain popularity so quickly. ADAS in automobiles is a great example of how the disruptive potential of embedded vision systems.
