With the official launch of DJI drones, light sensors have finally moved from behind the scenes to the forefront.

In the past, it was said that the data was awesome and powerful, and ordinary people did not have an intuitive understanding.

This time, people can finally get a glimpse.

China's top ten drone professional evaluation networks have all got the DJI Light series of civilian UAVs for the first time.

This time, the drone itself is not much different from the previous generation of products, the only difference is that it is equipped with a light sensor, so the sensor analysis ability is used as the evaluation standard.

On the morning of August 18, China's largest drone exchange group "Drone Home" posted the most professional evaluation report on its official public account and Sina Weibo;

Pixel size, which is a very important technical parameter in the sensor, the larger the size, the stronger the response to light, the greater the number of photons that can be received, and the higher the natural pixels.

Rating: ★★★★★

Comment: The existing software cannot evaluate the pixel size of the light sensor, but from the perspective of its pixel display rate, Tianyi should have mastered the core technology of the pixel!

Sensitivity, which has two physical meanings. One refers to the photoelectric conversion capability of the optical device, which has the same meaning as the response rate, and the other refers to the radiation power to the ground that the device can sense, which has the same meaning as the detection rate.

Rating: ★★★★★

Comments: The light sensor is by far the most powerful photoelectric conversion sensor I've ever seen, there is no one!

I give 101 points, one more point is not afraid of your pride;

Dead pixels, due to the limitations of the manufacturing process, are almost impossible for a sensor with a few million pixels to be free of dead pixels.

The number of dead pixels is also an important parameter to measure the quality of the sensor.

Rating: ★★★★★

Comment: I'm going to take back what I just said, it's almost impossible to happen, it happened with the light sensor, it has no bad points!

Yes, it doesn't have bad points! It doesn't have bad points! It doesn't have bad points! Say important things three times.

Can you imagine how powerful a sensor with no bad pixels is?

Anyway, after the test report came out, I didn't believe it, I thought there was something wrong with the software. What do you think?

Spectral response refers to the ability of a chip to respond to different wavelengths of light.

The higher the peak value of the spectral response curve, the flatter it is, the greater the short-circuit current density of the corresponding battery, and the higher the working efficiency.

From the perspective of solar cell applications, the more responsive it is, the more fully utilized light energy and the photoelectric conversion efficiency of solar cells can be improved.

Rating: ★★★★★

Comments: The peak value is more than 2 times that of existing sensors on the market, reaching 950.

Believe me, whether you can understand it or not, this spectral value is very, very powerful, and very stable, like a clear spring under the blue moon, without the slightest wave.

Since the drone we got this time is a smart battery, we can't give its performance on solar cells.

But I believe that such spectral responsivity should also shine in the field of solar cells.

Conclusion: I don't know how to evaluate the light sensor, because no amount of praise can express one-tenth of it, so I won't add to it.

Finally, I want to say that the DJI light series drones are worth owning!

......

Immediately behind the drone home, the "China Aerial Photography" released a special review.

Again, all the values are full marks, and there are no words of praise for the light sensor.

In the words of the editor-in-chief of China's aerial photography evaluation: the combination of light sensor and DJI drone is a combination of two swords, and it is a sight to behold!

Subsequently, professional public accounts such as "Yuchen.com", "Drone That Little Thing", "Lefei.com", and "Havoc in the Sky" all gave positive reviews.

You can't do it without giving a positive review.

If you want to say that there are any defects in the DJI drone, everyone can still accept it, but the drone home posts the various values of the light sensor, if you are black, it is not without conscience, it is simply shameless!

If someone said that someone had chosen to place an order because of "Tianyi production, it must be a high-quality product", and believed that the DJI Light series of drones would be glorious;

With the emergence of various professional evaluations, civilian UAVs have ushered in a big wave of upgrading.

Those who can afford to play aerial photography can be said to be not bad at money.

Just like fruit fans, everyone else is playing iPhone8, and you are still holding an iPhone5 or 6, not only do you have no face, but you don't even have a lining;

What's more, DJI Light series drone aerial videos have begun to appear on the Internet.

The image quality in the video is perfect, and the pixel expression at close range is stronger than that of professional cameras.

Such a terrifying technology shocked everyone, and those who had money placed orders as soon as possible.

Since the 20th, the gate of Guangyi Sensor Company has been jammed with various vehicles.

In addition to the drone companies increasing their procurement efforts, more are monitoring equipment manufacturers.

The excellent performance of the DJI optical series made them realize that the surveillance sensor will soon usher in a big wave of upgrading.

If you can't keep up with the development of technology at this time, you may be annihilated in the next wave.

This is a very normal thing.

Just like "Hikvision", "Dahua Co., Ltd.", "Uniview Technology", these leading enterprises of domestic monitoring equipment, they are all government-level suppliers.

Different from private, it doesn't matter if the camera is changed to ultra-high-definition, but the government should take into account social security, and the clearer the picture quality, the better!

It is precisely because of this that the government comes to purchase ultra-high-definition monitoring equipment, and you don't have it, so you can only find other manufacturers.

By the way, those SD, HD cameras will definitely go to other people's homes to purchase.

Do you think these monitoring manufacturers are not in a hurry?

......

At this time, in Guangyi Company, Zhou Zhenglei was in pain and happy.

Of course, the more orders, the better, but now the problem is that the production capacity cannot keep up. Although the price of a single sensor has been increased to 370 yuan, the order is still scheduled for the next year;

At the current rate of "grabbing money", at most two years, the cost will come back.

However, how much money to make is not something that Zhou Zhenglei considers, what he has to consider is market share.

According to Chairman Han Yi, the optical sensor will maintain its technical advantage for a maximum of 3 years, and maybe this time will be shortened;

The time set by Zhou Zhenglei for himself is two years, and Guangyi will at least win more than 50% of the global image sensor market share within two years.

Now the constraint on this goal is production capacity!

Zhou Zhenglei called Yao Xin, "Yao Gong, what's the situation with the faucet transformation?"

Yao Xin said with a smile on the phone: "A good news, a bad news, which one do you want to hear first?"

"Listen to the bad news first! The good news is kept to suppress the shock. ”

"The bad news is that the simulation demonstration at Huaqing University failed, mainly because the equipment was not accurate enough, so it couldn't be done. ”

"The good news?"

"The good news is that Seiko NPG has agreed to help us do the inverted film, and the simulation demonstration is exactly matched. If all goes well, the outer alloy parts will arrive at home by the end of next month. ”

Zhou Zhenglei stood up and said in surprise: "Really?"

"Hmm!"

"Great. Followed by Zhou Zhenglei said happily: "No guns, no cannons, we make them ourselves!"

"Hahaha......"

......

Han Yi was not idle here.

Originally, He Xiaoxiao came back to accompany her for two days, but something happened to the light and shadow.

The augmented reality device was seized after entering the U.S. Customs, and both sides knew why it was seized.

As a last resort, Han Yi personally went to the United States. It's not that the Americans are afraid of cracking the core algorithm, but that they are afraid that they will open their brains and see what is wrong with the device.

If U.S. Customs refuses to hand over the equipment, then he will have to consider the means to use it.

Fortunately, through the assistance and negotiation of the embassy, all the equipment was returned to the light and shadow vision company after 96 hours.

As he expected, the device had been disassembled, and the source code must have been copied.

But it doesn't matter, Surier said that with the current level of computers on Earth, even if a supercomputer is used to crack the core algorithm, it will take at least 2 years.

2 years is enough for Tianyi to develop.

When the time comes, apply for an international patent for the photon superposition method, and you can receive a soft hand in collecting patent fees.

Don't give money?
