Automotive Sensors: Cameras, Lidar, Radar, Thermal

Yesterday I (Paul McLellan) wrote a sort of overview of the Cadence Automotive Summit that took place in November, in the post Automotive Summit: The Road to an Autonomous Future. Today, the focus in on a key part of automating driving, namely sensors.

One of the first non-Cadence presentations of the day was Manju Hegde, the CEO of Uhnder… (more to this section of the article on the cadence website)
