The 64-line laser radar is currently used relatively more in autonomous driving, and of course there are companies that do 128-line laser radar. According to the relevant personnel of Sagitar Judging, the new generation P3 laser radar sensing solution is an extension of the Prometheus Plan announced by Sagitar in the last year. The P3 solution is specially developed for the automatic driving of L3 and above. System solutions. The P1 solution refers to a single 16-line laser radar system solution, targeting the low-speed autopilot market, and the market application is very mature; the P2 solution refers to a single 32-line laser radar system solution, which is mainly used for higher speed or safety performance requirements. High field; P3 solution has been upgraded in hardware and algorithm compared to P1 and P2 lidar sensing solutions.
Compared with the 64-line, the P3 solution uses a combination of multiple laser radars. The solution uses a 32-line laser radar (RS-LiDAR-32) in the center of the roof for all-round sensing, right in front of the car. The resolution of RS-LiDAR-32 can reach 0.33°, while the 64 line can only reach 0.4° with higher precision. A 16-line laser radar (RS-LiDAR-16) with a certain tilt angle is installed on both sides. Responsible for sweeping the blind spots on both sides, here is also the blind spot of 64. In general, the blind area coverage of the P3 scheme is more complete and the recognition accuracy is high.
3. What is the maximum number of wire harnesses that can be developed by Sagitar? What kind of mainstream application is in the future, or how many wire harnesses can solve the conventional needs?
Multi-line laser radar refers to the emission of multiple green laser pointer, which is more accurate than single-beam lasers. Multi-line laser radars currently used in driverless cars are 16-, 32-, and 64-wire; 64-line laser radars are expensive, and often a laser radar is more expensive than a car. In fact, simply talking about the number of lines is of little significance. The important thing is the resolution. Multi-line radars continue to increase the number of laser emitters and receivers, which can achieve very high numbers, but the resolution is not necessarily high, and the cost will increase. But MEMS is not the same, you can easily reach 100 to 200 lines, and increase the resolution without adding laser transmitters and receivers.
The 32-line green laser pointer radar of Sagitar has been mass-produced, and our P3 solution based on 32-line laser radar can meet the current high-speed automatic driving R&D needs of passenger cars. Sagitar is still the main strategic product for multi-wire bundle solutions and MEMS solid-state lidar solutions based on 16 and 32 lines, while MEMS is the most promising and fast-developing solid-state solution. (Editor’s Note: Sagitar Juchuang denied the continued development of 64-line multi-line products.)
There will be many automatic driving applications in the future. For different scenarios, the number of lines used is different. For example, in low-speed parks, the number of lines used is low, and the number of lines required for high-speed opening is high.
