According to reports, AT512 can achieve a standard distance measurement of 300 meters (@10% reflectivity), which is 50% higher than the previous generation product AT128; the longest detection distance can reach 400 meters, which is about 2 times that of similar long-range lidar on the market. times.

AT512 is equipped with Hesai's latest fourth-generation self-developed chip. This chip is further improved in integration compared to previous generations of products, and can achieve a maximum processing of more than 100 million points per second. This supports the AT512 to be able to process more than 100 million points per second. The ultra-high point frequency of approximately 12.3 million provides cars with image-level ultra-clear three-dimensional perception, achieving a globally uniform angular resolution of 0.05° x 0.05°, and a point cloud density that is 8 times that of AT128.

In addition, Hesai Technology also demonstrated the ET25 ultra-thin long-range lidar and a variety of other lidar products.

As a car-grade ultra-thin long-range lidar, ET25 is specially designed to be placed behind the front windshield. On the basis of achieving an extremely thin and light body of only 25 mm, it combines the ranging capabilities of 905 nm lidar (in reflection (under the condition of 10% rate) increased to more than 250 meters.

According to Hesai Technology’s previous disclosure, ET25 has recently won a designated project from FAW Group and successfully achieved a breakthrough in mass production. According to the plan, the next-generation flagship pure electric model of the Hongqi brand will be the first to use ET25 to create an in-cabin lidar smart driving solution.

According to reports, M3 is the fourth product of the Sagitar Juchuang M platform and the first ultra-long-range lidar of the M platform. M3 is built based on the mature two-dimensional scanning technology of the M platform and adopts a 940nm laser transceiver solution, which can achieve 300m@10% ultra-long distance measurement capability and ultra-high-definition three-dimensional imaging capability with an angular resolution of 0.05°x0.05°.

M3 has super small object detection capabilities and can accurately capture various small objects such as black tires accidentally scattered on the ground within 140 meters, traffic cones placed on the road within 280 meters, and children breaking into the middle of the road within 250 meters. Even in corner cases such as traffic accidents and extreme road conditions, M3 can help smart cars detect scattered obstacles in advance and avoid them in time, thus helping to increase the upper limit of L3 autonomous driving speed to 120km/h.

In terms of performance, M3 is superior to traditional 1550nm lidar, and its cost is 40% to 50% lower, its size is more than 50% smaller, and its power consumption is more than 30% lower.

In addition to the M3, Sagitar Jutron also exhibited the first pure solid-state automotive-grade blind-filling lidar E1 with self-developed chips, the self-developed and designed second-generation intelligent solid-state automotive-grade lidar M platform, and a new generation of customized multi-function lidar. Line lidar Helios series, 128-line lidar Ruby Plus series for L4 commercial operation, 360°×90° ultra-wide field of view close-range blind-filling lidar Bpearl, and true value & evaluation for advanced autonomous driving perception systems ToolchainReference.

Seyond Tudatong: Falcon and Robin series unveiled

At this exhibition, Tudatong displayed a comprehensive product matrix, including the Falcon series of image-level ultra-long-range main-viewing radars, the Robin series of forward-facing and wide-angle side-viewing lidars, and the perception software platform OmniVidi. Moreover, at the scene, the LiDAR Robin W mounted on NIO ET9 made its point cloud debut.

The Lingque W lidar, which is showing point cloud for the first time at CES, has an ultra-long range measurement capability that is twice that of similar products on the market, with a maximum detection range of 150 meters, nearly 10 times the angular resolution of similar products, and an ultra-wide angle With a field of view of 120°*70°, it can accurately perceive the surrounding environment and provide a safer, smarter and more comfortable user experience in assisted driving scenarios such as high-speed lane changes, unprotected turns in urban areas, and vehicle parking. At the same time, Lingque W has extremely low power consumption of less than 9W, is compact, and is easy to integrate and install.

Seyond Falcon series product Falcon Q also made its debut at this CES. Its special form can be integrated into the vehicle grille or front bumper design, taking into account ultra-long resolution and ultra-long detection range. It follows the Falcon platform architecture and has automotive-grade reliability. It is widely suitable for automatic/assisted driving front-mounted vehicles and complex Intersections, highways and rail transit and other fields.

Yijing Technology: The new SPAD lidar ZVISION EZ6 brings the price into the era of "1"

At the 2024 CES, Yiji Technology unveiled its new SPAD lidar, ZVISION EZ6, which was just released on January 2. As a cost-effective long-range lidar for ADAS front-mounted mass production, the innovation of ZVISION EZ6 lies in its use of a highly integrated SPAD architecture.

Compared with the traditional lidar architecture based on SiPM or APD, the SPAD architecture can replace most of the discrete components of the previous optoelectronic front-end → amplification link → analog-to-digital conversion → digital signal processing with one chip, greatly simplifying the architecture complexity, and The backend only needs to be equipped with an ultra-low computing power processor to complete all signal processing of lidar, thereby improving lidar sensing capabilities while reducing costs.

ZVISION EZ6 uses 192-line vertical scanning technology to achieve a ranging capability of 180m@10% and an angular resolution of 0.2°x0.1°. Due to the high degree of chip-based and integrated lidar achieved through architectural innovation, the overall cost of the EZ6 has been effectively reduced, with the price breaking the 2,000 yuan boundary and entering an era starting with "1".

In addition, thanks to the scalability of the SPAD architecture, Yijie Technology has also launched a full application scenario product matrix, which can evolve according to market demand and meet the differentiated needs of low-cost promotion of urban NOA applications. Some products are at CES A demonstration was also held on site.
