While there are numerous functions of lidar inside a vehicle, the primary use currently is in the automotive driver assistance systems (ADAS) sector — where the technology is used to help a vehicle navigate around other vehicles and pedestrians while parking and lane assistance and more.
Eventually, lidar will be one of the critical technologies used to enable full autonomous driving — Level 4 or Level 5 — sensing the world around it to allow the vehicle to make decisions.
Lidar is increasingly being incorporated into new car designs to enable or enhance many of these ADAS functions. Zvision’s ML-30s lidar is a short-range lidar that includes enhanced imaging effects, ultra-wide field of view and it is engineered for autonomous driving.
The following is a partial deep dive into the lidar conducted by TechInsights.
