Chapter 2135 Technology far ahead of the previous generation
It's so powerful, but seeing is believing. Let's see how it goes. Zhang Jun said after Zhou Yonghui finished speaking.
After hearing his words, everyone present nodded. Indeed, after hearing what Zhou Yonghui said, there was so much hype about it. It would be better for everyone to see with their own eyes how good this technology is.
After glancing at everyone's reactions, Wu Hao smiled at Zhou Yonghui and Lin Jiaming and said, "Since everyone is so interested, can you arrange an experiment to open our eyes?"
Seeing what Wu Hao said, Zhou Yonghui immediately nodded and said: "No problem, we will make arrangements now, please come here."
As he spoke, Zhou Yonghui led everyone to a very straight four-lane road next to the factory, and then introduced with a smile to everyone: "This is one of our test roads. Its length is 500 meters, which is enough for us to test."
This lidar is the best.”
As he spoke, Zhou Yonghui led everyone to an engineering vehicle, then pointed at the two square boxes with colored lampshades that the technicians were installing and debugging, and introduced them to Wu Hao: "This is the new generation of lidar we have developed. Its
The size is about the same as that of the previous generation product, and is basically the same as the lidar products on the market, but its performance is far ahead of the previous generation product, let alone those lidar products on the market.
Today we will show you the detection range and detection accuracy of these two lidars, please take a look."
As he spoke, Zhou Yonghui pointed to several large screens erected next to him and said to everyone: "After the lidar detection data 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 express understanding, Zhou Yonghui waved to the technicians who were debugging and preparing and asked: "Are you ready?"
The tester over there showed him the OK gesture. Zhou Yonghui nodded, then picked up a walkie-talkie and said: "Attention all departments, the new generation lidar test begins now.
Radar on!"
As Zhou Yonghui's order was issued, the two lidars were turned on, and Wu Hao and the others finally saw the images transmitted by the lidars on the big screen.
I saw the two large screens below displaying the detection images of two lidars at the same time. The difference is that one large screen displays the original detection data transmitted back by the lidar, which is the lattice 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 what makes up this sketch is not the light and dark lines, but small dots one by one. These small dots are combined by density.
, thus forming a very realistic black and white and gray sketch, which can also be called dot-spot painting.
The so-called point-and-point painting is actually a painting made by combining dots. It is the same as a sketch, but it is made up of dots.
What is displayed on the other screen is the processed picture. The entire picture appears white, and the objects and people in the picture are all displayed as white models.
Through these two pictures, everyone can clearly see the very detailed scene, the width of the road, the sand and 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 site, etc.
, the picture is very surprising.
Everyone even discovered that in the two sets of pictures, there was a small object that stood out about thirty or forty meters away from the lidar. Everyone took a look at it and decided to go there to see if it was true.
So when everyone arrived at the scene, they found that the wind must have blown a piece of garbage onto the road, so this thing was displayed. The piece of garbage was very small, about the size of a palm, but it was still displayed very finely on the lidar.
Through technical processing, a top-down picture appears on another large screen. Through this top-down picture, you can clearly see the information on the road. You can even vaguely see the texture of the asphalt on the road, as well as the paint on the road.
Traffic sign silhouette on the road.
You must know that these traffic signs are painted on the road, consistent with the road, and difficult to be detected by lidar. In this picture, they are very clear. But from this point, it can be proved that this new lidar
The excellent performance, 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. There is a car at the end of the road that will be driving towards us very quickly. We will experiment to see how far the lidar will detect this speeding car in the past two days.
Vehicles.
While Zhou Yonghui was speaking, several large screens displayed the first-person view of the car parked at the end of the road, as well as the overhead view taken by a high-altitude drone.
"Testing begins!"
With Zhou Yonghui's cry of "zero," the test began. Through the big screen, everyone can see the car rapidly accelerating on the road.
drop!
With a beep, the outline of the car has been displayed on the lidar. Through technical processing, everyone can clearly see the speeding information of the car on the lidar, and it is getting clearer and clearer.
"It was discovered at such a distance."
"About four hundred and thirty meters." Zhou Yonghui pointed to the data on the big screen and replied to Wu Hao and the others. "You see, at this distance the radar can already identify the car and its driving speed."
Four hundred and thirty meters, this distance is already very good, basically two to three times the detection range of lidar on the market today. Moreover, at such a long distance, it can identify the speed of the opponent's vehicle and the speed of the car.
The contours were modeled in real time, which is very impressive.
The speeding vehicle began to decelerate about a hundred meters away from the lidar, and stopped when it was twenty or thirty meters away from the lidar. An experimental tester wearing a racing suit and a helmet walked out.
The tester greeted Wu Hao and others, got in the car, and then drove the test vehicle away from the test site.
As for Zhou Yonghui, while letting the technicians prepare, he introduced to everyone: "Next, we will test the detection accuracy, detection resolution and scanning frequency of this lidar.
In order to increase the difficulty, we will fly some high-speed drones between 100 meters and 300 meters in front of the radar for testing to see how many drones our lidar can detect."
