Omnipotent Data
Chapter 88
"These two men are my suspects. If according to criminology, the possibility that this middle-aged man is the robber is as high as 80%! In his briefcase, maybe it's not some documents, but white Money Bai Yan looked at the crowd and said with a few pause.
"What, detective Bai, can I ask you a question?" Cheng Nuo raised his hand and said.
"All right, you say." The corner of Bai Yan's mouth reveals a touch of self-confidence.
He doesn't believe that a high school student can't solve the problem himself!
"Well, I just want to say that the middle-aged man in the photo has one missing segment of his right index finger." Cheng Nuo points out Bai Yan's mistake in good faith.
Bai Yan was stunned. He turned his head and looked at the right hand of the middle-aged man with a briefcase.
Sure enough, because the monitoring screen is a little fuzzy, Bai Yan was not carefully paid attention to this point.
Now, if you look closely, you can see that the middle-aged man's right index finger is missing.
In the photo of the robber, the index finger of the robber's right hand is completely normal. There's no one missing.
Bai Yan:
Bai Yan looks at Cheng Nuo speechless.
This kid How did you find out?
He himself almost stuck his face on the photo to find this detail.
The distance between Cheng Nuo station and the photo is at least three or four meters!
What Bai Yan doesn't know is that Cheng Nuo's data ability can appear in Cheng Nuo's eyes as long as it is within the scope of his vision, whether it can be seen clearly or not.
While Cheng Nuo was just collecting the data of the middle-aged man in the photo, he found that the length of his right index finger was abnormal, only 2.11cm! It was inferred that the man's finger was missing.
Bai Yan, who was demolished by Cheng Nuo, is now a little embarrassed.
The last second just promised that the middle-aged man was one of the robbers. The next second was slapped by Cheng Nuo's casual words.
It's a slap in the face Don't go too fast!
In the face of Yang captain and Jiang LAN two people slightly doubt the vision, in order to cover up the embarrassment of cough for a while. Then he took a deep breath and calmed down the feeling of beating people. Pointing to the photo of the second robber.
"Next, let me talk about the second robber. I found three suspects with similar physical features to the robber." Speaking of this robber, Bai Yan is obviously more confident. "These three people are selected from thousands of people. I'm 100% sure. Among these three, there is the robber we are looking for. "
Shua!
All of a sudden, when the flag of Baiyan is finished, Cheng Nuo slowly raises his hand.
Bai Yan's face was stiff, trying to make his tone appear calm, "Cheng Nuo classmate, do you have any questions?"
"Oh, I have a little question." Cheng Nuo smiles and goes to the white board and takes down the photo of the second robber.
Then, he said, "detective Bai, I found a problem. The arm lengths of the suspects you found are not the same as those of the robbers."
"Oh?" The side of the Yang captain to interest. "Little brother, how do you see that?"
Although the two photos are the same size, the proportion of people in the photos is not the same.
It's like the same person, a picture taken at close range, and a picture taken at a distance. The size of the picture is the same, but the proportion of the person in the picture is not the same.
That is to say, it is impossible to make a very accurate comparison between two different photos of people with different proportions. Bai Yan can do, can only estimate a approximate value.
In the face of Yang captain's question, Cheng Nuo shook his head and laughed, "Captain Yang, someone can't do it, and I can't do it."
Mr. Baiyan, who did not want to be named, turned black.
"You know what my nickname is?" Cheng Nuo glanced at captain Yang.
"What is it?" Captain Yang is very cooperative with Cheng Nuo this time.
"Famous detective edochuan nonan!"
Edogawa Nolan? Ah, Pooh, Noonan!
Captain Yang looks confused!
Bai Yan hugs his arm and silently looks at Cheng Nuo who has begun to pretend to be forced to perform.
Show! Please continue to show!
I'll watch you with the second battalion commander's Italian cannon!
Cheng Nuo went through the data in his mind, took the photo with the number two robber, and said.
"We certainly can't know the height of the robber and the length of his arm from the photos alone. But we can look at this. " Cheng Nuo pointed to the floor tiles on the floor of the bank in the photo and said, "the specification of the floor tiles in the bank is 300 * 400mm, that is, the length of the tiles is 40cm and the width is 30cm!"
"The number of floor tiles covered by the robber's shadow is 3.54. Then the length of his shadow is 141.60 cm! ""Minjiang Road branch of Qingcheng bank is located at 120.3354 degrees east longitude and 36.0748 degrees north latitude. The time is 7:05 a.m., and the solar shooting angle at this time is 32.14 degrees."
"From the above data, we can get the height of the robber is 178.28cm! According to the proportion, if the robber's arm length is 0.3397 of his height, his arm length is 60.57 cm! "
Cheng Nuo gently exhaled a breath, pointing to the three suspects found by Baiyan, said.
"Let's talk about the arm length of this man!"
Cheng Nuo pointed to the lamp post beside the man in the picture.
"Generally speaking, these street lamp posts are of uniform specifications. Therefore, the height of street lamp pole can be determined, which is 8.00 meters! Because the camera, the suspect, the street lamp, the three objects are not in one plane. Therefore, the height of street lamp needs to be calculated by angle. The angle between the street lamp and the camera is After the calculation of the above data, we can get the suspect's arm length is 58.35cm! There is still a big gap of two centimeters. So exclude it! "
"Well, let's talk about the second suspect that officer Bai found. We used the briefcase in his hand as a reference. The size of the briefcase is 16 inches, which is 53.33 cm, and
Cheng Nuo in front of the whiteboard, eloquent, reasonable analysis of the photos of several people's arm length.
Little did not know, Bai Yan three people already listen to be stupefied!
Jiang LAN needless to say, as Cheng Nuo's mother, watching Cheng Nuo clattered in front of the whiteboard and said a lot of completely incomprehensible numbers, she was shocked and a little relieved.
Look at my baby son how fierce, said more professional than the two police!
Bai Yan Leng Leng standing in place, the heart of the waves rolling. I didn't know what to say for a moment.
If Cheng Nuo's long list of data is just bullshit, it's OK. But the key is The data are really justified.
For a time, let Bai Yan a little doubt the feeling of life!
Oneself Can't even compare with a high school student?!
Well, you win!
You don't have to buy oranges for me. The orange tree doesn't need you to move all the way. Because Juzi te's self came over!
