According to the official Hesai Technology, it officially released its "performance trump card" product for the mass production vehicle market equipped with intelligent driving systems - 512-line ultra-high definition ultra-long range.LiDAR AT512. Officially called it the "pinnacle of comprehensive performance" of the Hesai AT series, it is mainly aimed at high-end intelligent driving mass-produced models that have extremely high requirements for performance, reliability, and safety.
It is understood that AT512 is equipped with Hesai's latest fourth-generation self-developed chip. By introducing cutting-edge technologies such as 3D stacking and optical noise suppression, it achieves comprehensive performance upgrades and full parameters with ultimate optical transceiver efficiency and top vertical integration capabilities while maintaining the same size.
AT512 can achieve standard distance measurement of 300 meters (@10% reflectivity), which is 50% higher than AT128.The longest measuring range reaches 400 meters, which is twice that of similar long-range lidars on the market..
It can keenly capture both vehicles and pedestrians at a distance of 400 meters, which greatly improves the vehicle's perception of the surrounding environment, allowing the vehicle to detect targets at least twice the distance in advance, increasing the reaction time of more than 40% for system safety decision-making, and protecting the safety of smart driving to the greatest extent.
At the same time, Hesai Technology also said that the first three generations of self-developed lidar chips have been successfully mass-produced and delivered on a large scale. Based on the successful experience of multiple self-developed chips, Hesai’s latest fourth-generation self-developed chip has reached a new level of integration.Able to achieve ultra-high performance with a maximum processing point of more than 100 million points per second.
Thanks to the greatly improved integration level of Hesai's fourth-generation chip, AT512 provides image-level ultra-clear three-dimensional perception for cars at an ultra-high point frequency of about 12.3 million points per second, with a globally uniform angular resolution of 0.05°x0.05°. The point cloud density is 8 times that of AT128, and it is also more than 10 times that of other similar long-range products on the market.
So far, Hesai Technology's AT series lidar has been designated for pre-installation mass production projects of more than 50 vehicle models by 15 leading OEMs and Tier-1 customers, including SAIC, FAW, Ideal, and Xiaomi.
Since its establishment,Hesai LiDAR’s cumulative delivery volume exceeded 300,000 units, making it the first vehicle-mounted LiDAR company in the world to achieve this milestone., and achieved a single-month delivery volume of more than 50,000 units in December last year, once again setting a new industry single-month delivery record.
