Military Technology

It's so powerful, but seeing is believing. Let's see what's going on. Zhang Jun said after Zhou Yonghui's words.

Hearing his words, everyone present nodded. Indeed, after listening to Zhou Yonghui's hype, we should let everyone see it with their own eyes to know how this technology is.

Glancing at everyone's reactions, Wu Hao smiled at Zhou Yonghui and Lin Jiaming and said, "Since everyone is so interested, how about you, can you arrange an experiment to open our eyes?"

Seeing Wu Hao say this, Zhou Yonghui immediately nodded and replied, "No problem, we will arrange it now, everyone please."

Speaking, Zhou Yonghui led everyone to a very straight four-lane road next to the factory, and then smiled at everyone and introduced: "This is one of our test roads, its length is 500 meters, which is enough for us to test. This lidar is out.”

Said that Zhou Yonghui led everyone to an engineering vehicle, and then pointed to the square box of the two-looking lampshade that the technicians were installing and debugging, and introduced them to Wu Hao: "This is the new generation of lidar we have developed. The size of the product is similar to that of the previous generation, and it is basically the same as the lidar on the market, but its performance is far ahead of the previous generation, let alone those lidar products on the market.

Today, we will show you the detection distance and detection accuracy of these two lidars, please take a look. "

Said, Zhou Yonghui pointed to the large screens erected on the side and said to the crowd: "After the detection data of the lidar comes out through the intelligent system, it will be fed back to these large screens in real time, so that everyone can watch it very intuitively. The whole experiment."

Seeing everyone nodding to show their understanding, Zhou Yonghui waved at the technicians who were preparing for debugging and asked, "Are you ready?"

The tester over there gestured OK to him, Zhou Yonghui nodded, then picked up a walkie-talkie and said, "Attention all departments, the new generation of lidar testing is now starting.

Radar is on! "

Following Zhou Yonghui's instructions, the two lidars were turned on, and Wu Hao and the others finally saw the images from the lidars on the big screen.

I saw the detection images of the two lidars displayed on the two large screens below. The difference is that the original detection data transmitted by the lidar is displayed on a large screen, that is, the dot matrix cloud data of the lidar. screen.

Therefore, in the eyes of everyone, the dot matrix cloud data picture on the big screen is a bit like a black and white and gray sketch, but the sketch is not composed of light and dark lines, but small dots. These dots are combined by density and density. , which constitutes a very realistic and realistic black and white gray sketch, which can also be called stippling.

The so-called point-and-point painting is actually a painting that is composed of dots, just like sketch painting, but it is composed of dots.

On the other hand, the processed image is displayed on the other screen. The whole image is white, and the objects and personnel in the image are displayed as white models.

Through these two pictures, everyone can clearly see the very detailed scene picture, the width of the road, the sandy ground on one side, the lawn on one side, the factory building on the other side, the outline of the building in the distance, and the people walking around the scene, etc. , the picture is very surprising.

Everyone even found that in the two sets of pictures, there was a small object that stood out about 30 to 40 meters away from the lidar. Everyone looked at it and decided to go to the scene to see if it was true.

So when everyone came to the scene, they found that the wind must have blown a piece of garbage onto the road, so this thing was revealed. This piece of garbage is very small, about the size of a palm, but it is still very finely displayed on the lidar.

Through technical processing, a bird's-eye view appears on another large screen. Through this bird's-eye view, you can clearly see the information on the road, and you can even vaguely see the texture of the asphalt on the road, as well as the brush on the road. Silhouettes of traffic signs on the road.

You must know that these traffic signs are painted on the road and are consistent with the road, and are difficult to be detected by lidar. But in this picture, it is very clear. But from this point, it can be proved that the excellent performance of this new lidar, especially the high resolution of detection, can accurately detect the roughness of asphalt roads and the smoothness of traffic signs, distinguishing the difference between the two.

First of all, what we are going to test is the detection distance. At the end of the road, there is a car that will quickly drive towards this side. Let's experiment to see how far the lidar will detect this speeding vehicle in the past two days.

While Zhou Yonghui was speaking, several large screens displayed the first-view picture of the car parked at the end of the road, as well as the top-down picture taken by the high-altitude drone.

"The test begins!"

With the sound of Zhou Yonghui dropping below zero, the test began. Through the big screen, you can see the car speed up quickly on the road.

Drop!

With a beep sound, the outline of the car has been displayed on the lidar. Through technical processing~www.readwn.com~ everyone can clearly see the speeding information of the car on the lidar, and more and more clearer.

"How far away did you find it?"

"About 430 meters." Zhou Yonghui pointed to the data on the big screen and replied to Wu Hao and the others. "Look, this distance radar can already identify the car and its speed."

430 meters, this distance is already very good, basically two to three times the detection distance of LiDAR on the market today. Moreover, at such a long distance, the speed of the opponent's vehicle, as well as the outline of the car, can be recognized and modeled in real time, which is very remarkable.

The speeding vehicle started to decelerate at a distance of about 100 meters from the lidar, and stopped at a distance of 20 to 30 meters from the lidar. An experimental tester in a racing suit and a helmet came out.

The tester greeted Wu Hao and the others, got in the car, and drove the test vehicle away from the test site.

As for Zhou Yonghui, while asking the technicians to prepare, he introduced to the crowd: "Next, we will test the detection accuracy of this lidar, as well as the detection resolution and scanning frequency.

In order to improve the difficulty, we will fly some high-speed drones for testing between 100 meters and 300 meters in front of the radar to see how many drones our lidar can identify and find. "
