Chapter 1107 Other Tests

At this stage, the performance of digital devices is advancing rapidly, but the rope around the neck is the battery.

The noble kidney machine also has the nightmare of charging three times a day, and the power bank like a urine bag used to be a necessary equipment that many people carry with them.

After flying for about half an hour, the elves hadn't had their fill yet, and Nehbet's battery was only a quarter left, which was close to a dangerous level.

After he gave the command, Nakhbet began to return automatically, landing almost exactly where it took off, and the rotor quickly stopped turning.

The eyes of the elves looking at it no longer have contempt and suspicion, but are full of envy and amazement.

Due to the high requirements of Weikang, it is necessary to ensure that the drone hovers above the head at all times during field inspections, so it is extravagantly equipped with several sets of spare batteries for rotation. Anyway, this is the funding provided by Binhai University, and this requirement is very high. Reasonable, not excessive.

Zhang Zian replaced Nakhbet with a spare battery, worried that its internal parts would overheat due to continuous flight, and waited for a while, but in fact it was only slightly warm.

Using this time, he took out another device to attract the attention of the elves.

"What is this?" They asked one after another. With the experience just now, they dare not underestimate these unassuming technological products.

"This is an infrared trigger camera I asked Professor Wei Kang for." Zhang Zian explained: "It is said that this thing can automatically take pictures, once a warm-blooded animal or moving object passes by the lens, it will automatically press the shutter ,Taking Pictures."

Although this thing is rare, it does not arouse the interest of the elves like a drone-it is nothing more than taking pictures, what is the difference between taking pictures by people and automatically by cameras?

Zhang Zian patiently clarified his thoughts.

When he saw the infrared camera in Wei Kang's office, he immediately felt corresponding worries—could this thing work against invisible elves?

Knowing the principle of the infrared camera from Wei Kang, he was even more worried, because the infrared camera is designed to be able to stand by for a long time in the wild regardless of day and night, and it can work normally no matter day or night. At night, once a warm-blooded animal or moving object is detected, the light-emitting diode will emit a faint red light to photograph the target.

So, if an invisible elf passes in front of the camera, triggering the camera's sensor and causing the camera to automatically take a picture, will the elf be captured?

Even if it can't be photographed, the scientific expedition team will think that a supernatural event has happened, causing panic.

As for the camera being broken, this is unrealistic, because the expedition team brought many cameras of the same type, so they couldn't be broken at the same time, right?

Therefore, he borrowed an infrared camera with a shameless face, intending to try it in advance, just in case.

Only then did the elves understand his intentions.

Lao Cha volunteered and asked Zhang Zian to make it invisible, then walked in front of the infrared camera in an invisible state, and walked back and forth several times at different speeds.

Zhang Zian took out the memory card of the infrared camera and inserted it into the phone to read it.

Fortunately, the memory card is blank, which means that the camera's sensor did not detect the invisible elf, so I put my heart back to my stomach.

His worries received polarizing comments from the elves. Old Tea praised him for his thoughtfulness, and Snow Lion scolded his mother-in-law for being suspicious...

Putting away the infrared camera, he touched the shell of Nehbet, it was already cold, and he was ready to start the second round of testing.

The first round was simply to test the flight state. This time he changed to a new test method, switching to the follow mode, letting Nakhbet target himself and keep hovering above his head. This is a simulated field trip. status.

"Xinghai, are you ready to be defeated by me? Now is the time to end your long winning record!"

With everything ready, he confidently challenged Xinghai to hide and seek, and he was not ashamed to play tricks on himself.

"Meow~ I'm ready!"

Xinghai is already eager to try, and can't wait to try the few good hiding spots that were overlooked from the sky just now.

"Well,

I'm going to start counting—this time with my eyes closed! 1, 2, 3..."

He closed his eyes violently, not denying that he had peeked while counting.

"Meow~ Laipi! Counting too fast!"

Xinghai kept complaining, his voice became erratic, changing from near to far almost instantly.

After tossing about for more than half an hour, the elves who got up early were a little hungry. Fina saw that Uncle Li had delivered breakfast to the pet shop through the drone just now, and hurried back to eat at the shop. Of course, Snow Lion followed suit; old tea and Femas likes to eat hot food, so he went back to eat first; the stray cats returned to the green field one after another, and Vladimir got some fresh news and information, and had something to deal with, so he left temporarily.

Richard didn't go, anyway, he doesn't need to eat hot cooked food, and here he can defecate freely.

"98, 99, 100! I'm going to start looking for you!" Zhang Zian finished counting 100 numbers very quickly and opened his eyes.

He gave Richard who was on the sideline a look, meaning to ask where Xinghai had gone, but only Richard rolled his eyes.

"Quack! You idiot! Do you think that having a drone is omnipotent? Anyway, in my opinion, a drone is not as good as an unmanned chicken!"

Zhang Zian didn't count on it anyway, rewinding the counting video through the remote control screen, this is already a blatant cheating.

However, Xinghai's actions were too fast. He stayed in place in the first second, turned around in the second, and disappeared in the third.

exo_me?

It seems that Xinghai has finally become serious after a long absence.

Zhang Zian did not admit defeat so quickly, he started to play the video just now frame by frame.

The gimbal camera equipped with the drone can record 4k video at a rate of 60 frames per second, that is, it can record 60 moments in the time of snapping a finger.

Unfortunately, he watched all 60 frames, but he still didn't see the process of Xinghai disappearing.

It was there at frame 30 and disappeared at frame 31.

It seems that it's time to give feedback to the manufacturer and let them provide a video mode with lower resolution but higher frame rate, such as 1080p/960 frame?

But he doubts from the bottom of his heart, even if the frame rate is increased to 9600, can he still capture the action of Xinghai?

He searched twice around the small green area, startled countless insects, and ended up with pine needles all over his face, but found nothing. In the end, he had to admit defeat, because the shop assistants had already started work, and he couldn't continue to delay here. time.

"Forget it, Xinghai, I'm not well prepared this time, let me give you a game!"

He doesn't lose when he loses, and he is still stubborn.

"Meow~ I won!"

Xinghai suddenly drilled out from nowhere, cheering for victory.
