The government currently proposes two main needs for real-time detection technology: road monitoring and security.

Road monitoring is the most convenient here. Whether it is highways, elevated roads, or important street intersections, the government has already deployed countless road cameras.

The scene required for this requirement is very fixed. The camera will not move, and the shooting angle will not change. It is just that cars are constantly coming and going in the picture, and sometimes pedestrians or non-motorized vehicles may appear.

Like highways and elevated roads, it's even simpler. There's basically nothing going around except cars, so it's very easy to do.

However, the government's needs for these images are different.

The basic technology provided by Meng Fanqi is to select some objects in the picture and label what they are.

But the government’s key demand for road inspection is not this. My video is full of cars, and why do you need you to label them as cars?

Why did you mark it out for me? I knew it when I took the photo. There are cars coming and going all the time on these roads.

Therefore, although the government's current intentions are very positive and they are very optimistic about Baidu, Baidu is very anxious and extremely busy. Robin Li and Yu Kai have not slept well these days.

This is a huge opportunity and a huge challenge.

If the demand can be completed in a short time, how big of an order will this be for so many road surveillance cameras across the country?

Of course, Li Yanhong is also very familiar with it, and there will definitely be a process of piloting it one by one and slowly advancing it. But he is confident that as long as the first order goes well, the subsequent advancement will be unstoppable.

Because the modernization and intelligence of this kind of thing will be a big political achievement, Li Yanhong knows very well what is the biggest motivation for the people in charge of the government.

In terms of political achievements, Li Yanhong could not think of any reason why the other party would not actively promote whiteness.

But having said that, the biggest problem now is that Baidu doesn’t know how to do it.

They have just taken over Meng Fanqi's code. Although they have digested the general approach, they still lack a deep understanding of why they do this in many places and the advantages and disadvantages of using other approaches.

If Meng Fanqi understands the government's needs in road inspection, he is quite familiar with it. The core points are speeding inspection and traffic violation inspection.

Among them, speeding detection is the main requirement. To put it bluntly, it is to directly calculate the real-time vehicle speed by comparing the changes in vehicle position between different frames in the video.

Since the camera angle is fixed, the interval between frames is also fixed, so as long as the distance traveled by the vehicle is calculated from the position change, the vehicle speed can be calculated.

But there is a difficulty here, that is, how do you know which vehicles in different pictures are the same one? This involves object tracking technology.

The government is not clear about the technical differences and difficulties. They think your test is quite smart, so I will just test the speed of the car and there will be no problem.

In fact, Baidu is overly optimistic. The current Baidu simply cannot add these functions to Meng Fanqi's code.

On the other hand, violation detection is just an add-on, not a core requirement.

Violation detection is nothing more than adding some detection of violations of traffic rules, such as whether you are wearing a seat belt or not.

Most cameras do not have this capability. They are so far away and hung so high that the seat belt cannot take pictures clearly. This aspect will not be really needed until the equipment is upgraded in the future, so there is no need to pay too much attention at the moment.

Road inspection is not easy to do, which is a headache for leaders. Workers like Wang Kai are mainly responsible for promoting some security-related scenarios.

Many of the functions in this part can already be taken into account in the current version given by Meng Fanqi, and some can be achieved with only slight adjustments.

For example, monitoring a specific area and prompting whether there are people.

Although there is surveillance, it is impossible for security personnel to stare at the screen all the time. Many important institutions have dozens of cameras, but they cannot see them even if they want to.

Do you expect security guards with ordinary income and salary to monitor surveillance every day? Stop daydreaming.

If real-time detection technology is added, the burden in this area can be greatly reduced. Wang Kai's trip is to promote this function.

However, he has been sitting at Yanjing Changping Branch for a long time, but no one has paid attention to him.

It was just that a policeman took a paper cup and poured him a glass of water at first, but there was no news after that.

Wang Kai himself is not that patient, but things like temper are not dependent on the situation. In the bureau, Wang Kai does not have the courage to say anything or ask for anything.

After waiting for more than an hour, no one paid attention to him. Wang Kai really couldn't hold it in any longer.

This visit was made in advance with their leaders, and it was not a door-to-door sales of insurance.

I couldn't help but walk inside and found that the police officers were working in groups of three or two, all staring at the surveillance video on the monitor. There were also several people lying on the camp beds nearby. It looked like they were exhausted and were resting at the moment.

"Director Tian, ​​what is going on?"

Although Baidu's headquarters is located in HD District, it is also very close to Changping District. The development of the science and technology park headed by Baidu has great benefits for Changping District, especially creating employment.

In general, in big cities, the director of the public security bureau is likely to also serve as a member of the district committee standing committee. Therefore, Tian Yunsheng, the Changping public security director and member of the district committee standing committee, is still very supportive of Baidu's work.

"Ah, Xiao Wang." Tian Yunsheng is a middle-aged man with a round face and a bit of richness, wearing a pair of half-rimmed glasses. "We have something urgent going on here, and we forgot to cancel this meeting with you.

”

Although it is Yanjing, many places within the jurisdiction of Changping District are still relatively remote. There are occasional cases in remote places, which are quite difficult to solve.

However, this case actually happened in a school, so it quickly aroused public attention and discussion, and the impact of the incident was extremely bad.

Although New Oriental Foreign Language School in Changping District is close to the Sixth Ring Road, there are still many universities and companies around it. Next door are Yanjing University of Information Science and Technology, Yanjing Normal University, and Yanjing Aerospace

"According to the introductions of the victims' friends and teachers, at the school's welcome party for new students in September this year, Xiao Yao, who served as the host of the party, attracted Wang's attention. After the party, Wang asked his classmates for Xiao Yao's

WeChat and added them as friends. After that, the two chatted occasionally, but the contact was not close. The next month, Wang expressed his love to Xiao Yao, but the latter refused on the grounds of study."

There was a policeman nearby who briefly introduced the background of the matter to Wang Kai
