Chapter 88 (2/2)

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!
