Although the achievement exhibition is still going on, the next people we will face are representatives from all walks of life and specially invited people.
Therefore, most of the exhibiting companies and units only left a few operation explanation personnel at the booth, while others were busy participating in industry exchange activities organized by the organizer.
However, Wu Hao and the others did not participate. Instead, following an invitation letter from military representatives and experts, they came to an equipment testing site in western Beijing to prepare for the next field test.
Previously, they had only introduced and demonstrated part of the performance of this 'battlefield sweeper' to leaders, military representatives and experts at the exhibition. Although everyone was amazed, it was not comprehensive.
In order to better understand the real combat performance of this 'battlefield sweeper' drone, military representatives and experts invited them to come over for field testing.
In addition, this battlefield sweeper drone has not yet undergone live-fire target shooting tests. This time, the conditions are just right for this 'battlefield sweeper' drone to give its skills a try.
Because of the hot weather, the test project started early.
The first test is the project of the drone flying through obstacles and searching for targets in complex terrain.
In complex terrain, building ruins and dense jungles have always been areas where the enemy is keen to hide, but it is difficult for our soldiers to clear them. Therefore, today’s test will start with these two.
The people who were cooperating with them in the test today were soldiers from a certain unit at the test site. Everyone was very interested in this test session, and there was a secret feeling of competing with each other.
The first test was to search, identify and locate people hiding in buildings. The test site has a seven- or eight-story building specially used for weapons and equipment testing and personnel training.
Soldiers playing civilians and armed personnel are hiding here. What the drone has to do is fly in autonomously, conduct reconnaissance and search of the entire building, and determine the location of civilians and armed personnel.
As for the number of civilians and armed personnel and the hidden lurking locations, the testers do not know, so this requires the drone to detect and search every corner of the building and not miss any fish that slip through the net.
"Let's get started." The leader waved his hand at Wu Hao.
"Okay." Wu Hao nodded and then motioned for Yang Fan to start.
After Yang Fan understood, he immediately controlled five drones and quickly flew towards the building. I saw five drones circling outside the building several times, then quickly found the entrance of the building and entered the building from different directions.
When the leaders, representatives and experts saw this, they immediately put down their telescopes and focused their attention on the large screen composed of several large TVs.
I saw five fast-moving pictures in the middle of the big screen. These were the real-time flight pictures transmitted from the white light lens on the drone.
The surrounding screens are pictures captured in real time by fixed cameras installed at different locations in the building, so that everyone can watch the entire test process more comprehensively from various angles.
"Are these all flying autonomously by drones now?" The leader looked at the fast-moving pictures on the screen and asked Wu Hao.
Wu Hao nodded: "We just designated an area for it, such as this building. It is up to them to make their own decisions on how to enter the flight search without our intervention."
Beep, beep, beep! Following several short warning sounds, a group of images on the screen zoomed in. I saw a drone hovering in a room, then quickly pointed the camera at the area where broken boards were placed in the corner of the room, sounded an alarm, and drew a red box in the picture.
There was no movement in the selected area at first, but as the drone's warning sound became louder, the soldier hiding behind the wooden plank finally couldn't help but push the wooden plank away and stand up.
Bang bang bang bang... Everyone watching in front of the screen applauded when they saw this. Although this was also viewed through a screen, it was far more vivid and real than what Wu Hao told in the exhibition hall before. At least the entire testing process was witnessed by their own eyes.
As the drones probe and search inside the building, more and more targets are discovered. Soon, a three-dimensional structural diagram of the building was produced on the screen.
The entire three-dimensional structural diagram not only truly restores the exterior appearance of the entire building, but also accurately restores the structure inside, and marks the floors and specific locations of civilians and armed personnel based on the detected positions.
"Did your drone start to record the relevant information of the area it flew through while it was detecting and searching, and simultaneously transmitted it back to the rear for regional scene restoration?" Zhao Hongzhe, Mr. Zhao couldn't help but look at the three-dimensional structure diagram on the screen. He said in surprise.
This technology is actually not new, because today’s civilian aerial photography drones can also do it. In fact, it is three-dimensional imaging and three-dimensional scanning technology, but it was integrated into this drone by Wu Hao and others.
The radar, laser distance and other related sensors equipped on the drone were originally designed to help the drone detect the flying airspace and avoid obstacles.
Later, the R&D team used this technology to reverse think and transmit back the obstacle data detected by radar, laser range and other related sensors, and then performed a series of calculations and synthesis, thus obtaining this three-dimensional scanned structural scene map.
The specific principle is a bit like the 3D scanners on the market, but Wu Hao's technology is much more complicated than 3D scanners.
Among other things, such a huge amount of scanned data can be accurately calculated and imaged in a short time, which involves a lot of high and new technologies.
Wu Hao nodded and explained: "We also want to give full play to its potential so that it can adapt to different combat environments.
As the saying goes, if you know yourself and your enemy, a hundred battles will never end. The current war is fought over an information gap. If we want to defeat the other party, we must understand the other party.
Although our goal is to have this UAV replace infantrymen in performing tasks in these complex environments, in many cases this UAV cannot perform as well as it should.
So we added this battlefield scanning three-dimensional imaging technology to capture enough information for our soldiers under such circumstances. Even if drones are unable to attack, soldiers can still analyze and prepare for combat based on the three-dimensional terrain map scanned by reconnaissance. "
"That's great. I think your drone can be used not only on the battlefield, but also in ordinary anti-terrorism operations."
“Usually in counter-terrorism operations, air fighters often take hostages and hide in complex environments such as buildings like this.
Because of the hostage relationship, we cannot launch a forceful attack without restraint, and the safety of the hostage's life must be our priority. If you are not careful, you may injure the hostages and cause the operation to fail.
Therefore, it is particularly important to capture specific information in such complex terrains. Only by mastering the environment of the hiding areas of the air insurgents and their specific locations. Only then can we initiate targeted actions to ensure that our actions are foolproof. "
