For the gift, start research and development of graphene batteries

Chapter 114 How can I not press the line in rainy and snowy days?
The performance of Xia Keyuan's vehicles was very eye-catching, and everyone's eyes were focused on Xia Keyuan's vehicles at this time.

Especially the netizens who entered the live broadcast room later were very surprised when they heard that the driving system of Xia Ke Academy was built by Jiang Ming and Professor Jiang.

You know, the news that Jiang Ming was nominated for the National Science Progress Award has spread.

Jiang Ming won this honor because he led the scientists of Xia Kingdom to develop carbon-based batteries.

Now coupled with autonomous driving technology, it is simply killing people.

It is not easy to make a contribution in one field, and now the automatic driving technology researched by Jiang Ming is so outstanding, it really stunned everyone.

Looking back at this autonomous driving challenge, it seems that the vehicles of Xiake Academy have indeed performed outstandingly.

In all aspects, the performance is quite eye-catching.

Especially the previous expressway entrance, although it was blocked, but after the staff opened the auxiliary intersection, they were able to control the vehicle to pass quickly at the first time.

When there are problems with the navigation of all vehicles, the driving system passes smoothly without any interference.

When everyone thought about it, they felt that Xia Keyuan's driving system was not simple.

There were many vehicles before, and everyone didn't connect things together. Now that I think about it, it's really unusual.

The vehicles of the Xia Ke Academy are now in the lead, driving on the muddy road.

Followed by Oudi and future vehicles.The other vehicles distanced themselves from the vehicle at the head.

Because this challenge is scored based on the performance of each link, not based on time.

Therefore, the driving system of Xiake Academy does not pursue speed too much, but takes stability as the standard.

Even so, since Xia Keyuan's vehicles were not affected by navigation before, overall, they are still ahead in terms of time.

The returnees, Odi and Future, knew that there was a vehicle from the Xia Keyuan ahead, and they were also struggling to catch up.

Everyone was not very surprised about Oudi's vehicle.

After all, the century-old Oudi, the technology is there.

Although Oudi has not launched electrified products for a long time, it does not mean that Oudi has no technical reserves in this regard.

When the new forces of electric vehicles headed by Tesla are vigorously promoting the process of new energy, in fact, within Oudi, it has been researching on electric vehicles for a long time and has developed multiple generations of electric vehicle products.

However, due to the good sales of Oudi's traditional fuel vehicles, Oudi is not in a hurry to bring electric products to the market, but instead devotes itself to research and development and accumulates technology.

When the electrification market was almost pushed forward by companies such as Tesla, Oudi launched dozens of improved models of traditional fuel vehicles in one fell swoop, and completely electrified the entire Oudi product line.

This speed is unmatched by ordinary enterprises.

The time and cost involved is a bit scary to think about.

Therefore, although Oudi launched new energy products late, its technical strength is not bad at all.

The outstanding performance in the autonomous driving challenge this time is also related to its perennial technology research and development.

As for another outstanding future, this is something that no one has thought of.

Although in the early stage of the challenge, the performance of future products is not very outstanding.But in the second half, the future is based on surpassing other vehicles and keeping pace with Oudi.

Careful netizens have discovered that in the future, the process of intelligence will indeed make a lot of progress.

At this time, everyone's eyes were fixed on Xia Keyuan, Ou Di and Future.

Xia Ke Academy represents a niche third-party autonomous driving research and development force.Oudi represents the traditional auto giant.As for the future, it is the strength of new energy vehicle manufacturing.

It stands to reason that the niche third-party autonomous driving companies should be the weakest and perform the worst.But the performance of Xia Keyuan broke through everyone's imagination.

Everyone has to admit that Xiake Academy's automatic driving technology is very strong, at least it has reached the first-class level.

The traditional auto giants themselves have great advantages in the car manufacturing industry, and they also performed well in this challenge.

As for the new car-making forces headed by the future, they have strong Internet attributes. In terms of automation, they also have the blessings of Internet companies.

The challenge is still going on, everyone will wait and see.

The second half of the journey was even more difficult.

First of all, the teams faced snow-covered roads.

Snow-covered roads are a very big challenge for the automatic driving system.

Snow-covered roads are not only difficult for the automatic driving system, but also for the manual driving system.The most important ones are the limited field of view, road recognition, and extended braking distance of the vehicle.

The extension of the braking distance of the vehicle is not a big problem.

Because the automatic driving system is computer-controlled after all, on snowy roads, as long as the braking distance is calculated in advance and operated within the set range, it will be fine.

Moreover, on snowy roads, the autonomous driving system will control the vehicle to travel at a relatively low speed, and the safety distance will be lengthened accordingly.

As for the limited field of view and road recognition, they all test the visual perception ability of the automatic driving system.

On snowy road sections, due to the influence of snow, there are problems with the recognition of road markings.

If you can't identify it, on urban roads, at most there will be problems with line pressure.But on the road around Qinghai Lake, the problem is bigger.

On the side of the road, there are some ditches.If it is not driven well, it is very likely that the vehicle will be driven into a ditch.

This involves the recognition of rain and snow weather and road boundaries.

If it is manual driving, the driver will judge where the roadbed is based on the traces of the vehicle in front and the distant scene, but for the automatic driving system, it is a bit difficult.

I saw the future vehicle, on the road, driving at a lower speed.

However, due to the problem of judging the road boundary, the future vehicles almost fell into the ditch beside the road several times.

Fortunately, the driving system finally judged it again and drove the car out again.

As for Oudi's vehicles, it is also facing the same problem.

Due to the unclear road markings, Oudi's vehicles, in many cases, drive on the line, which is a serious violation of the rules.

As for the vehicles of Xia Keyuan, they are a bit different.

I saw that the vehicles of Xia Keyuan were all driving while looking for ruts.Moreover, although the marking line is not very clear, the vehicles of Xia Keyuan surprisingly did not touch the line. Compared with the two, the vehicles of Xia Keyuan seem a bit unusual.

On the Dou Ya Dou live broadcast platform, all the netizens are a little surprised that Xia Ke Academy can operate without pressing the line in snowy weather.

You know, Oudi has suppressed it many times.

Although everyone understands that with such heavy snow, most of the marking lines are covered, and it is understandable that there will be pressure on the line.

But with the comparison of Xiake Academy, it seems that there is something wrong with the technology of Oudi vehicles.

"Mr. Zou, what do you think of the performance of the Xiake Academy's vehicles?"

Keke saw the netizen's barrage, and also raised the netizen's question in a timely manner.

"To be honest, I don't understand the technology of Xia Ke Academy."

Zou Ming rarely admits his lack of cognition.

"According to the current performance of the Xia Ke Academy, the vehicles of the Xia Ke Academy can obviously recognize the road markings. But this recognition method cannot be guessed."

Zou Ming added.

"Yes, I agree with Mr. Zou's point of view. If there is an explanation, it can only be explained by the technicians of Xiake Academy."

Wang Shuang also said with a frown.

To say that the two have been researching in the field of autonomous driving for so many years, they really did not expect the basis for the Xia Ke Academy to judge the markings.

In fact, according to past experience, they have not paid much attention to the issue of marking lines in rainy and snowy days.

After all, the markings are affected by rain and snow. If it is said that the automatic driving system cannot recognize it, then the human eye cannot recognize it.

In this case, it is understandable that there is a pressure line.

And whether you have pressed the line or not, you can't tell from the video taken by the traffic police, it can only be said to be inferred.

The traffic police will not punish such road violations.

Of course, although there is no penalty, it is a violation of the rules after all.If there is technology to avoid it, that is the best.

Both of them had never heard of it before, but now, seeing the performance of Xia Keyuan's vehicles, they knew that this problem was solved.

Zou Ming and Wang Shuang's explanations did not dispel the doubts of netizens, but intensified their discussions.

All of a sudden, the problem of road marking recognition in rainy and snowy weather has become a hot topic.

When Jiang Ming learned from other people that the performance of Xia Ke Academy had become a hot topic, Jiang Ming was also a little bit dumbfounded.

However, Jiang Ming would not say anything about the identification of rain and snow weather markings. This involves a core strategy of the Fuxi system and is a commercial secret.

Of course, this question is simple and simple. The core secret lies in the reconstruction technology of road markings.

The traditional driving system uses a camera for visual sensing, and directly uses the visual sensing images.This is normal operation, but when it is not recognized, the marking is assumed to be absent.

This situation is actually a misjudgment.

It is not because there is no marking line that it cannot be recognized, but because it is blocked by an object and cannot be recognized.

In this case, Fuxi system will take the operation of reconstructing the marking line.

On the one hand, according to the navigation map and combined with big data, the width of the road surface and the number of vehicles are generally located.

Afterwards, the driving system re-determines the width of the road and the possible number of vehicle lanes based on the visually sensed images, and compares the two to confirm the difference.

Finally, the markings are re-marked on the model based on the values ​​of the ground markings and infrared induction.

In fact, the most important thing is the infrared recognition function of the marking line.

The camera on the Fuxi system is equipped with infrared sensors, which can sense the calorific value data of different areas.

According to the experience gained from Jiang Ming's inheritance, the markings on the ground need to reflect the road light at night, so the current mainstream marking paints in Xia Kingdom are all metallic paints.

This kind of metallic paint may not be visible in the daytime, at most the ground markings are a little bright and reflective.

But at night, under the illumination of the light, the reflectiveness of the ground markings is particularly strong, and the markings can be seen from a long distance.

Due to the use of metallic paint, its performance under the infrared camera has a different calorific value from that of the road surface.

According to the calorific value, mark the marking lines that appear, and then combine the navigation data to redisplay the marking lines on the model, which is why the Fuxi system can recognize them.

It sounds simple, but in practice, it is extremely complicated.

In particular, the thermal imaging problem of metallic paint under the induction of infrared cameras is difficult to identify without detailed data.

In fact, the Fuxi driving system will not only analyze the calorific value of the ground markings, but also analyze the calorific value of all objects reflected in the camera.

Thermal imaging data is also a very important reference data.

Of course, in the current Fuxi system, there is not much data about calorific value, and the calorific value data of different objects has no obvious characteristics.

However, Jiang Ming believes that with the popularization of autonomous driving and the Fuxi system collects more data, with the blessing of massive data, I believe that the Fuxi system will summarize the characteristics of the calorific value data of most objects.

If this step is really reached, the follow-up Fuxi system will be supported by traditional imaging and thermal imaging. I believe that the automatic driving system will be even more powerful.

But in Jiang Ming's heart, these are not the eyes of the real autopilot system.

The real driving system needs to collect image data, thermal imaging data, and electromagnetic field data.

Everyone, every object, in the large magnetic field environment of the earth, has a corresponding magnetic field characteristic, and the summary and identification of this magnetic field characteristic will be more accurate than the image.

This is the most powerful eye of the automatic driving acquisition system.

It's just that although Jiang Ming knows that it's okay to do so, in Xiaguo, and even in the entire Water Blue Planet, the data on electromagnetic field perception is basically zero.

In order to make this detection system, it is necessary to improve the knowledge of the entire industry and collect as much electromagnetic field data as possible, otherwise it will not be successful.

Thinking of the problems he was facing, Jiang Ming felt dizzy.

The current driving system's demand for electromagnetic induction is not as great as imagined. With image and infrared collection, it is enough for the time being.

The challenge continued. At this time, all eyes were on the vehicles of the Xia Keyuan team and the Oudi team.

Xia Ke Academy, naturally performs the best. It can ensure that the vehicle drives within the marking line in rainy and snowy weather, just like having a third eye.

Although the Oudi team has pressed the line many times, it can only be said that its performance is relatively good, and it can be regarded as a strong competitor.

As for the future, after the situation of almost turning over the ditch just now, everyone is not very optimistic about it.

This kind of operation is too fatal, it is a serious mistake, and it will surely deduct a lot of points. This is doomed, the ranking in the future will not be very high.
