Chapter 61: Deficiency in perfection

"Why did it choose this route instead of the closer route?" Luo Kai, who had rarely spoken, asked at this time.
因为 "Because this is the optimal route." Wu Hao smiled back.
Luo Luokai heard his answer and asked: "The best route?"
浩 Wu Hao nodded, then pointed at the big screen and said, "Look, the drone cluster has planned a total of six flight paths, including the shortest and the longest.
However, the one selected by the drone cluster is not the shortest of the several schemes, but rather this one has many twists and turns.
对照 If we carefully check the topographic map, we can see that the two shortest routes are flying along the valley, which is really good, and it can also avoid radar detection.
But did you notice that there are several sharp bends below 90 ℃ in the valleys that the two routes pass by? If a large fleet of aircraft passes these sharp turns, it can easily cause a large number of drones to crash, so it has abandoned this recent route for safety reasons.
As for the farthest one, there is no doubt that the route is too far. "
After hearing Wu Hao's words, everyone nodded while watching the big screen. Indeed, compared to other routes, the flight route chosen by the cluster is the most suitable.
"Wait a minute, why are there so many drones crashing." Just as everyone was talking, Yang Xuehai suddenly shouted at this time.
Everyone heard the words and looked at the past, and saw that there were some red dots on the trajectory of the drone cluster on the screen, which means that the drone has fallen. If it turns into a black spot, it means that the drone has crashed and lost contact, and the black spot is the location where the system finally accepted the signal.
鸿 Zhao Hongzhe frowned and asked, "Is there anything found in the aerial drone surveillance images?"
"There is nothing special for the time being." A technical staff reported.
浩 Wu Hao looked at the screen, then raised his voice: "Tune over the video recorded by the drone with the camera in front of the cluster."
报告 "Report, UAV No.021,078 is in the forefront of the aircraft group, and the video has been transmitted to the big screen."
At the same time, surveillance video images from the perspective of these two drones appeared on the big TV screen.
When everyone saw this, they stared at the big screen, but found nothing unusual for a while.
鸿 Zhao Hongzhe asked, "Is there anything unusual at the observation points along the way?"
报告 "Report, the drone passed through the valley area, leaving the field of view of most observation points. Only a few observation points can track the flight status of the drone cluster, but the distance is too far, and nothing abnormal is found for the time being."
"The number of falling drones is still increasing, and there are currently more than a hundred." Gao Feihang stared at the data on the screen anxiously reporting.
"Xiao Wu, is there something wrong with the autonomous control system of the cluster?" Yang Xuehai worried at him.
浩 Wu Hao heard some words, but turned to look at Yang Fan who was staring at the data on the other side.
Yang Fan shook his head slightly at him, signalling that no abnormalities were found on the system control program.
Where did the problem occur?
Wu Hao stared at the video images on the big screen and thought about it. He had never encountered a crash before for no reason.
"Lao Zhao, stop if you can't do it. We have achieved great success. There is no need to take this risk." Yang Xuehai then suggested to Zhao Hongzhe.
I heard Professor Yang's words, and everyone immediately focused on Zhao Hongzhe.
At this time, Luo Kai on the side also said: "I think Yang is right, let's stop for a while. We will test it after we find the problem. Anyway, it's not a short time."
Zhao Hongzhe was hesitant after hearing the words of the two. He turned his gaze to Wu Hao, who was still thinking, and asked, "Little Wu, what's your opinion?"
I heard Zhao Hongzhe's words, and everyone looked at him again. But now Wu Hao is still immersed in his thoughts.
"Little Wu?"
"Ah?" Wu Hao was awakened and said, "What's wrong?"
"What are you thinking?" Zhao Hongzhe asked at him.
Wu Hao felt the crowd focus on him, then shook his head with a smile: "Maybe, I already know the reason."
Zhao Hongzhe suddenly became interested when he heard what he said, and quickly asked, "Oh, what's the problem?"
"Did you notice the lush vegetation and trees in the valley?" Wu Hao answered with a smile.
"What do you mean?" Zhao Hongzhe flashed in front of his eyes, and all of a sudden came over.
Wu Hao nodded and said, "This is not a problem with our system programs and drones at all, but the data is inaccurate.
的 The data we have obtained, especially the terrain data, are based on mountain terrain mapping. Very few of these tall and dense trees are noticed.
So I analyze that our falling drones are likely to be blocked by these tall trees and vegetation, causing a fall failure. "
"Yes, it must be this reason. The terrain and landform data we have all come from the previous database of surveying and mapping, not what we survey and map in real time.
在 During this period, a mountain may suddenly grow in these mountains ~ EbookFREE.me ~, or there may be more buildings, electric wires, or obstacles such as landslides. This can cause the data to be mismatched with reality and cause the drone to crash. "
When I heard Wu Hao's explanation, Yang Xuehai was excited and agreed.
Luo Luokai heard the introduction of the two, and was slightly disappointed: "In this case, our technology needs to be optimized and improved."
浩 Wu Hao smiled and comforted: "In fact, it is not as complicated as everyone imagines. Generally, we cannot encounter this situation.
What we tested today is just under the set limit environment.
I want to solve this problem is very simple, I already have two solutions here. The first UAV and the existing system technology do not need to move, and only need to import the latest topographic and geomorphological mapping data to solve this problem.
Second, upgrade the drone hardware and system software. Drones can be equipped with detection radar, range sensors or other detection equipment.
In this way, the surrounding ground information can be detected in real time while the aircraft is flying. Not only can these obstacles be avoided, but the location of the target can also be accurately searched and detected. "
Zhao Hongzhe nodded and smiled: "Xiao Wu is right, it is not as complicated as you think. Our drone does not have these sensors, so it will cause problems in such strange areas."
"Compared to the first solution, I am more optimistic about the second improvement solution. In this way, our drone cluster can perform tasks in unfamiliar areas at any time, greatly increasing its use environment and scope, and Can increase its power. "Yang Xuehai nodded, and looked at Wu Hao with a smile on his face.
