Chapter 94 Loopholes
After a brief period of "organizing", Du Jin seemed to feel that he had become omniscient and omnipotent in an instant. He could accurately remember everything in the room at the moment and roughly think about its materials, uses, and methods of use. Of course, , in order to prevent his own memories and values from being "distorted", Du Jin did not transmit the philosophical and historical knowledge of the Blood Seal World, but he did not dare to say anything. According to Du Jin's current knowledge, he is no different from an encyclopedia. , but most of this knowledge is stored in Du Jin's mind subconsciously.
At this stage, unless Du Jin deliberately thinks about a certain theoretical point or the corresponding technical creation in reality, he will think of this part of the knowledge. If he is allowed to speak for himself, he may not be able to directly associate the information he wants, and Du Jin does not. He didn't worry about this, because he could only wait now. Before "Xiao Ai" came back, Du Jin couldn't actually do much at the moment. Otherwise, if he returned to the present world, someone else would need "Xiao Ai's" network intrusion ability. In this place, then Du Jin just got himself into trouble with a blind eye. Although he had just "learned" some knowledge about high-level programming in this world, he had not gone through practice and practice, and the two worlds were different. In the future architecture system, if there is an invasion of the same level as the previous rescue of the "reef", then Du Jin will never be able to replicate his previous success.
And if Du Jin is still in the "observation period" to put it bluntly, the governor does not fully believe and trust Du Jin. Although the time difference between the two worlds is very small, it does not mean that there is no possibility that Du Jin will be like this when he travels back to the present world. If someone comes to look for him, he may find something abnormal about him, so now Du Jin can only wait, hoping that people from the Star Port will check "Xiao Ai's" "body" and return it as soon as possible. When Du Jin was worried about what to do, the equipment that previously carried "Xiao Ai" was already being scanned by a rather huge instrument.
The people arranged by Tan Jialiang had no intention of dismantling the equipment for inspection. Through specific scanning and detection equipment, they could use high-precision copying technology to make a one-to-one copy with a precision beyond the nanometer level, and then they could Various inspections, disassemblies, and studies will be started on the generated replica to confirm whether there are potential dangers or whether there are some hidden secrets.
As a circular scanning terminal scans around the handheld terminal device, the operator obtains a data model of its structure and materials. This speed is absolutely unimaginable on earth. 3D scanning is A technology that can scan objects in a variety of ways and convert their physical three-dimensional information into a 3D digital model. It is mainly divided into two major types: "contact" and "non-contact" 3D scanning. The difference between these two types, as the name implies, is whether the object is touched or not. If it is touched, it is contact type, and if it is not touched, it is non-contact type.
Contact 3D scanning technology uses a sensing probe to contact the surface of an object to obtain the position coordinates of the point touched. Because it needs to contact the surface of the object bit by bit in order, scanning the entire object takes more time than the non-contact method. However, because it is in contact with the object, the accuracy is higher (some equipment is even as high as 0.1um). It is commonly used For precision measurement and quality inspection, in general, compared with non-contact scanning, contact scanning has higher accuracy. However, due to the need to contact the surface of the object, soft objects or grooves that the probe cannot penetrate cannot be used. Scanning, which also means that there is no reliable way for many precision parts except to disassemble them one by one and scan them in advance.
Compared with contact 3D scanning equipment, non-contact 3D scanning equipment is commonly seen on the market. Non-contact types are roughly classified into two types: "active" and "passive." The difference lies in whether there is an active light source. 1. Active type. Active type can be divided into two categories: 1. Time of Flight (also called depth sensing technology, hereinafter referred to as TOF). The basic principle of TOF technology is similar to that of bats and dolphins. The measured object emits a "wave" and then receives the "wave" that bounces back from the measured object. The distance of the measured object is calculated based on the round trip time of the "wave". Currently, most TOF technology equipment on the market uses invisible light (including infrared light, laser light, etc.). TOF technology is also mainly used for large-scale scene scanning, including ranging, building scanning, terrain and landscape surveying, etc.
2) Structured light method (Structure Light). Structured light method is the mainstream 3D scanning technology application method in the industrial and manufacturing fields. Structured light 3D scanning technology is based on the principle of optical triangulation and consists of optical projectors, cameras, and computer computing systems. The principle is: the light source projects an image encoded according to certain rules and patterns to the object being measured, and the encoding pattern is affected by the surface shape of the object. Modulation produces deformation. The deformed structured light is captured by a camera at another location. The three-dimensional shape of the object can be determined through the positional relationship between the camera and the projection light source and the degree of deformation of the structured light. According to the different beams projected by the projector, they are divided into point, line, grating, surface structured light, etc.
The biggest advantages of the structured light method are high precision and fast speed, which is more suitable for short-distance and high-precision measurements. Because of its high precision and high resolution, structured light is currently the mainstream technology used in industry and manufacturing. Different light sources, pattern types, and calculation methods have led to fixed and handheld 3D scanning equipment. Compared with TOF technology, the disadvantages of the structured light method are that it is not suitable for large-scale scanning, and it is also easily affected by the environment and the surface material color of the object. Scanning effect.
Of course, there are other more convenient methods. The most representative technology of passive 3D scanning is photogrammetry. Photogrammetry is a long-standing technology used in fields such as topographic surveying, surveying, and historical site protection, but in recent years it has also been used to create backgrounds for computer games and animations. It is different from the active light projection method. It uses 2D digital images to shoot the same object from different angles and then uses professional software to calculate, analyze and simulate to restore the 3D model. The biggest feature of photogrammetry is that it does not require equipment such as 3D scanners and can be produced using ordinary photos. However, this method can only imitate the appearance, and it cannot do anything with slightly more precise objects.
Moreover, these current 3D printing technologies, even if they include military-grade high-precision technology, cannot obtain the external and internal structure data model of the scanned target through integrated scanning, let alone analyze its constituent materials. Therefore, this kind of almost "cracking" scanning and copying technology and equipment would definitely be the dream of the military of all countries if it were placed on the earth. By then, no matter the stealth fighter of the M country or the missile engine of the polar bear, Or high technology such as Xia Guo's drones. There is no confidentiality at all in the face of this unsolvable technology. If the cost limit is ignored, the other party only needs to get one of your samples to take yours. New weapons are put into service.
Of course, this kind of technology is extremely confidential even in the blood-seal world. Although the federation is extremely eager for this cross-era technology of the Xia Kingdom, there is nowhere to find it. The machine that Tan Jialiang masters may be the last one in the entire federation. Of course, this technology is only applicable to the current world. In the space age at the federal level, there are still many targeted prevention methods. For example, the simplest one is to spray paint on the surface and interior of equipment that needs to be prevented from scanning and copying. Anti-detection coating, when the scanning ray is scanned, what is collected is just a black shadow, and the material data obtained is at best the material of the coating. Moreover, before the establishment of the Federation, there were still countries in the period. If the truly advanced equipment was If it is unable to contact the authorized users and deployers for a certain period of time, it will directly self-destruct on the spot or destroy all functional chips, leaving the enemy's subsequent search forces and R&D forces with nothing to do.
With the completion of the scan, a replica that was exactly the same as the entity was born. However, after many dismantlings and targeted research and cracking, the scientists and engineers of Ganymede could only "recycle" it. "The female officer who planned it shook her head.
"No matter what angle or technical means, this device only has a very primitive AI, and its storage core is some experimental data that initially has no breakthrough value. We did find a few "Eden" pictures. There are spacecraft structure diagrams and scientific research project tables, but there are no confidential documents related to the United Church and the Federation. Of course, we are starting to check whether there is any encrypted information in those daily logs and files, but this will take some time. "
Listening to the report from the head of the inspection department, the officer had actually roughly understood the results of the investigation and ruled out the possibility of finding encrypted documents later. There seemed to be no problem with Du Jin's identity. According to the officer's intuition, , instead of staring at Du Jin, a "dull" researcher, it is better to arrest and investigate the former Xiaguo officer named "Li Mengyan", who is also a woman's sixth sense and a veteran of the intelligence department. , this woman definitely has more secrets to find than Du Jin, but she knows very well that the Governor has no intention of investigating "Li Mengyan", a former Xia officer, but rather intends to win over her.
"Forget it, my mission has been completed, let the planning department handle the rest! My vacation time is coming soon."
After silently sorting herself out, the female officer left the inspection department with the inspection results and data and walked towards the command platform of the star port.
