Livox lidar sensors designed for L3/L4 autonomous driving

Livox Technology Company has introduced two high-performance, mass-produced lidar sensors, the Horizon and Tele-15, which feature a new scanning method that offers improved sensing performance at a low cost.

The lidar sensors are aimed at L3/L4 autonomous driving, smart cities, mapping, mobile robotics and more.

“The growth potential of the lidar industry has been hindered for too long by ultra-high costs and slow manufacturing rates,” said Henri Deng, global marketing director at Livox. “Livox seeks to change this by providing access to high-quality lidar systems that are easily integrated into a wide array of different use applications. Through our technology, we hope to be the catalyst for the rapid adoption of lidar in the quickly growing industries of autonomous driving, mobile robotics, mapping, surveying and more.”

The environment scanned by a Livox sensor increases with longer integration time as the laser explores new spaces within its field of view (FOV). A Livox Mid-40 or Mid-100 sensor generates a unique flower-like scanning pattern to create a 3D image of the surrounding environment.

Image fidelity increases rapidly over time. In comparison, conventional lidar sensors use horizontal linear scanning methods that run the risk of blind spots, causing some objects in their FOV to remain undetected regardless of how long the scan lasts.

The non-repetitive scanning method of the Livox lidar sensors enables nearly 100% FOV coverage with longer integration time.

The Horizon and Tele-15 are high-performance lidar sensors designed for L3/L4 autonomous driving applications. The Horizon has a detection range of up to 260 meters with a horizontal FOV (HFOV) of 81.7° which can cover four road lanes at a distance of 10 meters. Its FOV coverage ratio is comparable with a 64-line mechanical lidar at the integration time of 0.1 sec. Using five Horizon units enable full 360° coverage.

Made for advanced long-distance detection, the Livox Tele-15 offers the compact size, high-precision and durability while vastly extending the real-time mapping range. The Tele-15 can scan 99.8% area within its 15° circular FOV at 0.1s.

The Tele-15 can successfully detect an object up to 500 meters away. As a result, Tele-15’s performance allows autonomous driving systems to detect remote objects well in advance, providing more reaction time even at high speeds.
