Becoming the richest man starts with making complaints

Oh, that's pretty cool!

It seems that Boss Xiao has just been KO'd, and this slender-eyed comrade is still in a mood.

It doesn't matter, it doesn't matter if you disagree, I'll let you feel the pressure of disagreeing.

It takes a lot of time to come here today. How can I, Cao Shen, not make enough money!

Cao Shen opened his notebook and showed everyone a video of his modified "high-precision map".

The modification, of course, is to hide sensitive information.

Kind words to all:

"This is a demo of a high-precision map of a ring road in Beibu City. I hope the country can open up map surveying qualifications."

The map industry involves national security, and Dongguo map surveying and mapping qualifications are strictly restricted.

The same is true in the original world. By 2020, only 24 domestic units will have this qualification.

The United States is more open in this regard, so companies around the world that are engaged in autonomous driving basically put their research and development and testing work in the United States.

As for Boss Jia making cars in the United States, it’s hard to say whether it’s for this reason...

In addition, China’s road patterns, including curvature and elevation, are confidential information.

All map systems published in China, including electronic maps, must use GCJ-02, an encryption algorithm that adds random deviations to geographic information, to encrypt geographic location for the first time.

When decrypting, you need to use a "deflection plug-in". This plug-in will produce random jitter, with a maximum amplitude of 1.7 meters. It will actually have a relatively large impact on the "accuracy rate" of high-precision maps.

For this reason, when our country is researching autonomous driving, there are still many difficulties that need to be overcome.

However, confidentiality is necessary and everyone is trying to find a better balance.

In addition, domestic senior surveying and mapping talents are very scarce.

As of 2018, there were only 16,000 registered surveyors, while there were 18,000 national units and enterprises with surveying and mapping qualifications, with an average of only one person per company.

Autonomous driving is a technology worthy of research and advancement, and deserves more efforts.

Dongguo is stricter on the confidentiality of map surveying than the original world. Now, except for units within the system, no company has obtained this qualification.

If Cao Shen wants to do something, the state must open this qualification to enterprises.

Slender Eyes sat up straight and said warily:

"Map? What are you doing this for?"

Old Yu also became more energetic: "Is this the new technology you just mentioned!"

The dark-faced man became more enthusiastic: "Cao Shen, tell me what good things you have done!"

Cao Shen pointed at the computer screen and explained:

"This is a high-precision map, which is the data basis for the perception layer and decision-making layer of autonomous driving."

Old Man Yu's eyes lit up: "Made for self-driving cars!"

Cao Shen nodded vigorously: "Yes, it is still under study."

Old Yu stretched out his hand and pressed it: "Wait a minute!" Then he said to the assistant beside him:

"Go and ask the leader of the industrial port to come over. I saw him here today, talking about cars!

He must be interested in cars!

Don’t forget to tell him, autonomous driving! "

The assistant nodded in agreement and ran out quickly.

Old Man Yu said with slender eyes: "Autonomous driving is a good thing! You must support it!"

Cao Shen smiled in his heart and said, it's just as I expected, there's no way you don't want it!

Slender eyes said to the assistant beside him:

“Then please invite the leaders of the Science and Technology Commission to listen.

The issue of maps involves national security and cannot be decided by just one of our ministries. "

If you can find help, so can I!

Slender eyes turned sideways:

"Oh, you guys who are in charge of technology only care about the good stuff, what if we, the ones who are in charge of safety, do it!

The Internet you have created is becoming increasingly difficult to control. "

The dark-faced man patted him on the shoulder:

“Don’t stop eating because of choking, let’s rejuvenate the country through science and technology!

Your working methods and methods must also keep up with the times. You are there to protect the work, not to cut off the flow and reduce expenditure.

Besides, it is said to be difficult to manage, but with the power of technology, your management tools have also increased.

Video surveillance and the filters we are going to make will improve your management breadth and efficiency! "

Looking at Cao Shen, he pointed at his slender eyes and said:

"Xiao Cao, I have a suggestion. If you do this autonomous driving in the future, you will be able to see the driving data in the background. You can just provide him with a copy of this data later."

Cao Shen nodded: "Okay! No problem."

What I like most is providing interfaces to access each other!

The dark-faced man chuckled and patted the slender-eyed shoulder: "Don't worry this time."

He rushed to the old man and said, "Why haven't they come yet!"

Old man Yu put down his teacup and joked:

"You think humans can fly, but you get impatient when technology is mentioned, wait a minute!"

The dark-faced man said with a smile: "Aren't you impatient? You're not curious!"

Yu Laotou Yile: "Of course we pay attention to the new information technologies and new products of technology companies."

The dark-faced man said with a smile: "Mr. Cao, this company is under your control, just be happy." He folded his hands and sighed.

I'm envious, why don't I have such a capable guy at my disposal?

As he was talking, a tall man strode in from the door and said as he walked:

"Autonomous driving, where is it?"

Old Man Yu pointed to the chair next to him and motioned for him to sit:

"I just introduced you, this is Cao Shen from Shen Technology, who is here to report on his work today.

He is studying autonomous driving and has just started talking about high-precision maps. "

The tall man laughed at Cao Shen: "Hey, Cao Shen has started to study this! Is the Internet boring?"

Of course Cao Shen knows, he is a master of technology.

If someone had told him about autonomous driving today, he might not be so interested.

After all, he is in charge of the industrial sector, and he still knows the level of domestic automobile research and development. Even ADAS assisted driving is still a very new concept, and the penetration rate is still very low. It is too early to talk about autonomous driving now.

But Cao Shen, although he is not in the automobile industry, and his career is like a mountain, but his skills are proven, and he may be able to tell something new.

At this time, a tall and energetic old man with gray hair walked in. This was the leader of the Science and Technology Committee, and he had a very majestic temperament.

After he sat down, he said in a very kind manner:

"You go on, I'm just here to listen and learn what young people are doing."

When the tall man saw everyone gathered, he rolled up his sleeves and signaled to Cao Shen:

"Come on, come on, listen attentively and speak carefully!"

Slender Eyes asked:

"First of all, tell me why this autonomous driving requires high-precision maps.

I think that kind of autonomous driving uses cameras, radar, CPS, etc. to determine the location. "

The information security of the map is related to his work, so he is most concerned about this.

Cao Shen nodded and said:

“The autonomous driving process is divided into perception layer, decision-making layer and execution layer.

Driving is directly related to the life safety of users, so there must be extremely high standards.

Therefore, the information transmitted from the perception layer to the decision-making layer must be redundant. "

The dark-faced man answered:

"Yes! I understand! Redundancy is a necessary condition for system robustness."

Everyone:

Hey, those who understand technology should not interrupt casually, okay?

You get it, we’ve just started!

What the hell is robustness? Let’s talk human talk!

Cao Shen said:

"Yes, what the leader just said about the use of sensor signals such as cameras, radars and GPS is actually the possibility of missing information and not being processed in a timely manner.

For example, the weather is bad, the light is bad, the signal is bad, etc.

Of course, this may also happen with high-precision maps.

Therefore, the perception layer needs all these redundancies to complete the information as a basis for decision-making. "

The tall man nodded and said:

“High-precision maps are used for environmental perception and can form redundancies with the output results of sensing equipment such as laser radars and cameras to improve the accuracy of identification.

In addition, high-precision map information can provide auxiliary information for sensing device identification. "

"Yes, only when complete sensory information enters the decision-making layer can the algorithm make judgments on specific driving issues based on the multi-dimensional information provided by high-precision maps and Internet of Vehicles technology, output vehicle control signals, and hand them over to the executive layer for execution," said Cao Shen.

With slender eyes and a frown, he gave the handsome man a wink:

"Are you saying that high-precision maps are necessary for self-driving?"
