Denso develops new vision and radar sensors for 2018 Lexus LS

The stereo vision sensor uses 3D image processing techniques called “dense stereo matching” to detect obstacles of different shapes, including pedestrians, vehicles, and guardrails, as well as empty road spaces marked by lane lines. This enables autonomous emergency braking and automatic steering control to avoid obstacles. The product’s highly sophisticated cameras can also better detect pedestrians at night.

The new millimetre-wave radar sensor provides higher pedestrian detection performance in a more compact module. More frequent radio waves emission also detects obstacles with higher sensitivity, particularly pedestrians approaching from the sides. Furthermore, the product’s radar beam can be emitted over a wider angular range, without requiring a mechanism to adjust the angle, as with previous versions. This reduces its size by 60 percent compared to conventional radar sensors, thereby allowing for easier installation.
