(June 30, 2022, Beijing) Benewake was invited to attend the 20th China Automotive Supply Chain Conference, which is held once a year, jointly guided by the Ministry of Industry and Information Technology, the People's Government of Hubei Province and the China Machinery Industry Federation, and co-sponsored by the China Association of Automobile Manufacturers, Wuhan Municipal People's Government and Wuhan Economic and Technological Development Zone, and is one of the most authoritative and influential industry events in China's automotive industry. It is one of the most authoritative and influential industry events in China's automotive industry.

Dr.Yuan Li, CEO of Benewake, gave a keynote speech on the topic of "LIDAR beyond the limits of human perception", sharing Benewake's practical experience in the automotive industry chain and the company's strategic technology route.

512-Line LIDAR Guaranteed HD resolution and ultra-long range

From the basic biological characteristics of the entire human eye, there is a limit to perception. Humans have more than 500 neurons, which can be refreshed once in 11 milliseconds, and the effective resolution is about 1 km (people can see most of the road clearly in about 1 km, most of the objects / human "effective perception" is about 1 km), but for pure darkness, high intensity light, high intensity of several environments, the limitations come to the fore. LiDAR can make up for the limitations of human eye vision, objectively speaking, most LIDAR beams are only a few dozen to a couple of hundred now, and can not fully match the clarity of the human eye.

"Why do we want to do 512 lines of such high performance LiDAR, in addition to allowing car customers to enjoy the marketing dividend to its users, we think more from the practical considerations." Li Yuan further said, "Resolution and distance are bundled, in the actual case of 100 meters and 200 meters, for 128-line radar, 100 meters can guess a person and a car, but at 200 meters, the model and human movement are indistinguishable. If it is 512 lines radar, the shape of the person and the type of the car can be seen when the distance reaches 200 meters. This is why we are challenging the difficult 512-line index, which is closely related to engineers who really do the autonomous driving algorithm and domain control."

In the direction of vehicle LiDAR, Benewake has laid out three generations of products. The first generation was the first to do auxiliary LIDAR, only trigger sensor; the second generation to do intelligent driving auxiliary LIDAR; the past few years focused on doing the third generation of high level unmanned driving main LIDAR.

The new generation of LiDAR laid out by Benewake is extremely excellent in performance, with a field of view of 120°×25.6°, a measurement range of 200M@10% reflectivity, a resolution of 0.05° longitudinally, which is equivalent to 512 lines, adjustable horizontal resolution, and a frame rate of 10HZ. Currently designed in accordance with 7×24 hours, it is adapted to various scenes and does not need to pay for a single scene. In terms of next generation products, the safety, reliability and stability of the whole radar are what car manufacturers care most. Benewake has fully considered the functions including dirty, blocking detection, real-time closed-loop work, especially the real-time fallback system. When the main system has problems, our backup system can make the car stop safely.

The overall scanning period of this LiDAR is 100ms. Benewake cleverly improves the effective point cloud duty cycle, so that the time to generate a frame of point cloud is shortened to 80ms. It is well known that there will be transmission time delays during data transmission. Benewake uses this unique scanning method to save data generation time, so that the time to generate a frame of point cloud + data transmission time<100ms, in the high-speed driving scenario , which will be a huge gain to really take safety and efficiency into consideration.
