Military Technology

However, under the processing of the technicians, the detection picture of the lidar was quickly adjusted and played slowly.

Please take a look, here are several test simulated obstacles that we have placed on the road, they range in size from ten centimeters to one centimeter. We test to see if these simulated obstacles can be detected at a speed of 100 kilometers per hour.

Under Zhou Yonghui's introduction, everyone stared at the big screen, and soon a simulated obstacle was selected by the detection and discovery box, followed by the second, then the third, and the fourth.

In the end, all the simulated obstacles were identified, and there was a burst of applause from the scene.

But at this time, Zhang Jun raised a question that he was more worried about.

"Is it really necessary to apply such fine detection accuracy to automatic driving? Not all road conditions will be so good. If these tiny objects or potholes are identified and avoided, what should the car do? Driving, the passenger experience in the car may not be so good."

Hearing Zhang Jun's question, everyone thought for a moment and nodded. Indeed, if it is replaced by those roads with poor road conditions, even if it is a road with a long road age, there will inevitably be some potholes and some rocks and debris. Is it really necessary to avoid these things?

Of course, it is best to avoid them, but such ordinary avoidance of these tiny objects, constant steering, acceleration and deceleration, the riding experience of the passengers in the car must be very poor.

So hearing this question, Zhou Yonghui shook his head with a smile and said, "We have already thought about the question you asked.

In fact, this is a problem to be dealt with in autonomous driving technology. What we are doing now is the performance test of lidar. From this point of view, the higher the accuracy and resolution that lidar can detect, the better.

As for whether to use it or not, this is an issue to be considered in the autonomous driving technology.

In other words, it can be used without it, but not without it. For these problems, we can perform subsequent upgrades and optimizations through the system algorithm, but the hardware is not, so we must improve the performance of the hardware as much as possible from the beginning.

Since you mentioned this issue, let me first introduce to you and everyone how we handle this.

Although these tiny objects of one or two centimeters, potholes have no effect on the driving of the vehicle, nor will they cause any damage to the tires of the vehicle.

But this matter is not absolute. Among these tiny objects, some of them will still have a very large impact on the driving of the vehicle, and even cause the car to crash.

For example, iron nails of one or two centimeters, sharp objects, etc., once these things are pressed by the tires of high-speed vehicles, they are likely to cause tire bursts. The vehicle itself is not very stable at high speed, and a sudden tire blowout may cause the vehicle to change direction, install other vehicles or road guardrails, or even rush out of the road, rush off cliffs, and so on.

Even a sudden tire blowout may cause the vehicle to roll over and so on, which can be said to be very dangerous.

With such fine detection capabilities, we can perform corresponding processing on the automatic driving system. For example, it actively avoids the detected sharp objects, so that it can greatly reduce the emission of sharp objects piercing the vehicle tires.

For most ordinary tiny objects, they are selectively extracted, for example, they can be directly filtered, ignoring their existence. In other words, when conditions permit, make gentle avoidance, try not to crush these tiny objects and so on.

For some roads with poor road conditions, we can plan the driving route in a targeted manner, avoid large obstacles as much as possible, and so on. We have already applied this technology and related algorithms to our "Wangshu" intelligent lunar surface inspection rover on the moon. "

In the process of Zhou Yonghui's speech, the test continued, and the speed of the test vehicle had reached 120 kilometers at this time. When such a speed is really driving on the highway, it doesn't seem to feel anything. But as bystanders, everyone could finally feel how fast the 120-kilometer car was.

Not only that, on the entire test road, there is a test vehicle driving from the opposite side, also at a speed of 120 kilometers per hour. This also means that if the two test vehicles do not slow down, the relative speed can reach 240 kilometers in an instant when they meet, which is a very terrifying speed.

At the same time, there are many drones circling in the air. Whether these objects can be recognized at such a fast speed also makes everyone full of expectations.

Identify it, identify it!

With the exclamations of everyone, I saw that the screen had already displayed, the test test that was opened on the opposite side, and some drones in the air.

The distance is estimated to be 400 meters.

Three hundred and ninety-one meters. Zhou Yonghui glanced at the data on the screen and replied.

awesome!

At such a speed, it can be detected at such a long distance, which really surprised everyone and praised them.

Wu Hao looked at the speeding vehicles on the road, then smiled and waved his hands: "Okay, I'll stop here when I see it."

No, the 140-kilometer test has not continued. When Zhang Jun, who was watching happily, heard his words, he instantly became unhappy.

In response, Wu Hao said angrily: "I still have work to do, stop playing.

This result is already very remarkable, and it is meaningless to continue the test, and it is a waste of time. "

After finishing speaking, Wu Hao turned his head and said to Zhou Yonghui: "Okay, the test is here, we have seen everything that should be seen."

Zhou Yonghui nodded when he heard the words, and then called the technician to start the test~www.readwn.com~ Wu Hao glanced at the test vehicle on the test road that was gradually decelerating, and then asked Zhou Yonghui: "What is this lidar about? time to put it into the market.”

Hearing his question, Zhou Yonghui immediately turned his head to look at him and replied: "The relevant testing work for this lidar technology has been completed, and it stands to reason that we can launch it into the market at any time.

But, we're going to wait. "

and many more? Wu Hao looked at Zhou Yonghui with a puzzled look when he heard the words. Not only him, Zhang Jun and the others also looked at Zhou Yonghui, some wonder why such a good technology was not applied, but had to wait.

Yes, wait. Zhou Yonghui nodded and explained: "If we just sell hardware equipment, we feel that it is too much of a loss, so we plan to launch a bundled sale with our new generation of autonomous driving technology.

Moreover, our new generation of autonomous driving technology is also based on the optimization and upgrade of the new generation of lidar and other technologies, so the more matching between software and hardware, the performance will naturally be stronger. "
