Livox introduces mass market LiDAR sensors for L3/L4 autonomous driving applications
Livox Technology Company introduced two high-performance, mass produced LiDAR sensors, the Horizon and Tele-15, which the company says feature a scanning method that offers improved sensing performance at a fraction of the cost of traditional LiDAR units.
“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.”
High-performance and compact design
The environment scanned by a Livox sensor increases with longer integration time as the laser explores new spaces within its field of view (FOV). The company says that the 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 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, according to Livox. The non-repetitive scanning method of the Livox LiDAR sensors reporteldy enables nearly 100% FOV coverage with longer integration time.
Designed for L3/L4 autonomous driving applications
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 meters1 with a horizontal FOV (HFOV) of 81.7° which can cover four road lanes at a distance of 10 meters and 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 with only 5% of a cost of a 64-line mechanical LiDAR, which can be beneficial if customers want to scale up their robotaxi fleets to hundreds or thousands of cars or if OEM and Tier 1 want to consider LiDAR for their future models with L3/L4 autonomous driving functions.
The company says that the Livox Tele-15 is made for advanced long-distance detection, and 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 which outperforms 128-line mechanical LiDAR sensors currently available on the market. The Tele-15 can successfully detect an object up to 500 meters2 away, which Livox says is hardly achievable by human eyes or other sensors at this cost. As a result, the Tele-15 allows autonomous driving systems to detect remote objects well in advance.
Livox says it has optimized the hardware and mechanical design so that a compact body3 of Horizon and Tele-15 sensors enable customers to easily embed units into existing and future vehicle designs.
Designed for reliability and safety
Additionally, Livox says that its mass production capability enables the company to conduct intensive reliability tests. More than 2900 units of Livox LiDAR sensors have been individually and thoroughly tested for use in various conditions. Each unit has a false alarm rate of less than 1/10000th, even in 100 klx sunlight4. Livox says the Horizon and Tele-15 can operate in temperatures between -40 ̊F to 185 ̊F (-40 ̊C to 85 ̊C). Additionally, the entire sensor of both Horizon and Tele-15 is also IP67 rated.
Traditional mechanical LiDARs have a number of rotating electronic components in order to achieve a 360° coverage, which may increase the failure rate. The product design of Livox LiDARs has no electronical moving parts beside its rotating prism(s), which the company says increases its reliability and length of working hours.
Each sensor’s laser power meets the requirements for a 905nm Class 1 laser product to IEC 60825-1(2014) and is safe for human eyes5.
