The government's current demand for real-time detection technology mainly focuses on two aspects: 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 is very fixed. The camera will not move and the shooting angle will not change. However, there are always cars passing by 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 inspections 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 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 it 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 smoothly, 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 + whiteness, Li Yanhong could not think of a reason why the other party would not actively promote it.
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 an in-depth understanding of why many places do this and the advantages and disadvantages of using other approaches.
If Meng Fanqi understands the government's needs in road testing, he is quite familiar with it. The core points are speeding detection and traffic violation detection.
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? This involves object tracking technology.
The government is not clear about the technical differences and difficulties. They think your test is quite smart. I will just test the speed of the car and it will be fine.
Baidu is actually 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.
For most cameras, this capability is not available. They were all so far away and hung so high that I couldn’t even take a clear picture of the seat belts. This aspect will not really be needed until the equipment is upgraded in the future, so there is no need to pay too much attention to it now.
Road inspection is difficult 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 minor adjustments.
For example, monitoring a specific area to prompt whether there is someone there.
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, and 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 feature.
However, he has been sitting in Yanjing Changping Branch for a long time, but no one has paid attention to him.
At first, a policeman took a paper cup and poured him a glass of water, but there was no news after that.
Wang Kai himself is not that patient, but temper matters also depend on the situation. In the game, Wang Kai does not have the courage to say anything or ask for anything.
After waiting for more than an hour, but still no one paid attention to him, Wang Kai really couldn't hold it in any longer.
This visit was made in advance with their leader, 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 the Baidu headquarters is located in HD District, it is also very close to Changping District. The development of the science and technology park led by Bai Du has brought great benefits to Changping District, especially in terms of employment.
In general, in large 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 turned out to be in a school, so it quickly aroused public attention and discussion. The impact of the incident was extremely bad.
Although New Oriental Foreign Languages School in Changping District is close to the Sixth Ring Road, there are still many universities and companies nearby. Next door is 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 him as a friend. 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 Wang Kai to the background of the matter.
"I didn't expect that Wang, who failed to court, would do such a despicable thing."
