The debate on the technical line of autonomous driving has been going on for several years, and the debate is mainly between lidar and cameras.
Lidar is disliked by Musk
Tesla cars achieve autonomous driving mainly by cameras and millimeter-wave radar , as well as the algorithm behind it. As for lidar, Musk is somewhat disgusted. He once said: Lidar is a stupid thing to get into the car.
Lidar can measure the distance and angle between a car and an object through the reflection of electromagnetic waves. Compared with millimeter-wave radar, lidar has a shorter wavelength and more accurate measurements.
Since lidar has more advantages, why does Musk not like lidar technology? One of the important reasons for
is that lidar is too expensive. The development of lidar is difficult, the assembly is complex, and the production cycle is long, which has kept the price of lidar high. Considering the cost issue, Musk is naturally reluctant to use lidar.
At the same time, the reliability of lidar is also a problem due to the influence of internal construction in actual use.
is becoming more and more popular in China
However, even so, the momentum of lidar is still unstoppable, and it is becoming more and more popular in the Chinese market.
Before halfway through 2021, my country has released three mass-produced models equipped with lidar. Not only in China, but also in the international autonomous driving market, the application of lidar is becoming more and more common.
Geek Park quoted an entrepreneur in the lidar industry saying that lidar has become the first choice of many car companies, not overnight, but thanks to the overall accumulation of the past five years.
After years of research on , the reliability of lidar has been improved. It is reported that the completion of lidar is 90%, and the rest are parts that need to be refined. Lidar has become an irreversible trend.
Huawei's 's persistence has not been in vain
Huawei's entry into the field of lidar is even more because this has set off a wave in this field.
Huawei's actions are very rapid. In 2019, Huawei began to develop lidar in-house. Today, Huawei has built the first Pilot production line for automotive-grade lidars.
Huawei has technical strength, talent pool , and has strong software and hardware genes, because Huawei's entry into the game is undoubtedly a big challenge for many previous lidar giants.
But for the industry as a whole, Huawei's arrival was a surprise. The price of lidar is generally thousands, or even tens of thousands of dollars , but Huawei has to reduce the price to 200 dollars, or even 100 dollars .
Facts have proved that Huawei's insistence is not in vain, and the route of lidar is not wrong. Moreover, Huawei's efforts have also made the lidar route more certain.
In the future, let us wait and see how autonomous driving will develop.
