When the vehicle is unloaded and unloaded, the height of the shock absorption is different.

For example, when Chen Yan got on the car yesterday, the body of the Tank 500 would sink slightly.

Although the degree of sinking is very small, it is easily felt by Chen Yan due to the soft suspension of the car.

Of course, the commercial car driven by Zhao Xiaohu also has the same thing.

Zhao Xiaohu's height is only slightly shorter than Chen Yan, but he is still almost 1.8 meters tall.

And it's rather burly.

The weight is about 90 kilograms.

For such a strong man to sit in a commercial vehicle, the shock absorption height of the commercial vehicle will inevitably be lowered.

And here's the problem.

Chen Yan found in the video that the commercial vehicle under surveillance had two slight vibrations.

The amplitude was very small. Chen Yan originally thought it was caused by Zhao Xiaohu's actions in the car, such as lying on the seat and turning over.

However, after the vibration, the gap distance between the wheel eyebrow and the tire changed.

Of course, this gap changes very little.

As Chen Yan said, only two millimeters!

What does this mean?

This shows that during this time period, the load in the commercial vehicle has changed!

"Zhao Xiaohu, you are the driver, you should understand what I mean."

"Just based on the change in the gap between the vehicle's wheel arch and the tire in this video, we can determine that you were not in the car from 11:16 to 12:38."

"Then why did you lie?"

"Where have you been during this time?"

"Moreover, you actually left the commercial vehicle through the trunk..."

hehe.

"Zhao Xiaohu," Chen Yan paused the video on the tablet: "If you were me, tell me if I have any reason to doubt you, you would be the murderer!"

At this moment, Zhao Xiaohu was no longer as calm as before.

There were no beads of sweat on his forehead.

Monitoring room.

Li Hong and Liu Qingshan were also staring at the video at this time.

"Lao Li...has this gap...changed?"

"The gap..." Li Hong was confused: "I...didn't see it."

2 mm.

Of course ordinary people can't compare.

Especially in video recording.

The concept of space is subject to certain distortions.

Because the video shooting also has different angles and distances.

In this way, the displayed spatial distance will change.

For example, a person who is 1.8 meters tall.

In reality, you can easily determine his approximate height.

But in the video, if there are no other reference objects, it is difficult to judge the specific height.

In particular, surveillance is usually done from above.

This makes it more difficult to judge distance.

Even if Chen Yan turned on the visual gene lock yesterday, he didn't notice it.

If he hadn't driven the car himself and felt the details of the vehicle's shock absorption and sinking, and then used his ability to freeze images to compare every frame before and after the vehicle shook, he wouldn't have discovered it.

"Zhao Xiaohu, you should understand that as long as I find the vehicle you were driving, let you in, let you out again, and compare the degree of the vehicle's sinking, I can confirm whether the images in the video are true."
