Chapter Ninety-Four: Loopholes

After a simple "tidying", Du Jin seemed to feel that he had become omniscient and omnipotent in an instant, everything in his room at the moment he could accurately think about the materials and uses that constituted it, and how to use it, of course, in order to prevent his memory and values from being "crooked", Du Jin did not transmit those philosophical and historical knowledge in the blood-imprinted world, but he didn't dare to say anything, according to Du Jin's current knowledge, he was no different from an encyclopedia, It's just that most of this knowledge is stored in Du Jin's mind in a subconscious way.

At this stage, unless Du Jin deliberately thinks about a certain theoretical point or the corresponding technical creation in reality, he will remember this part of the knowledge, usually if he says it himself, I am afraid that he will not be able to directly associate the information he wants, Du Jin did not worry about this, because he can only wait now, before "Xiao Ai" comes back, Du Jin can't actually do much at the moment, otherwise when he returns to the present world, if there is a place that needs the ability of "Xiao Ai" network intrusion, then Du Jin will go to trouble himself with a black eye, Although he had just "learned" some knowledge about high-level programming in this world, without practice and practice, coupled with the different future architecture systems of the two worlds, if there was an invasion of the level of rescuing the "reef" before, then Du Jin would definitely not be able to replicate the 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 none, if Du Jin travels back to the present world, someone here comes to find him, it is possible to find his abnormality, so now Du Jin can only wait, hoping that the people in Xinggang will return the "body" of "Xiao Ai" as soon as possible after examination, and at the same time, when Du Jin is worried and doesn't know what to do, he used to carry "Xiao Ai" The device was already on a very large instrument for scanning.

The people arranged by Tan Jialiang did not want to disassemble this equipment for inspection, through specific scanning and detection equipment, they could use high-precision replication technology to replicate one-to-one with an accuracy beyond the nanometer level, and then they would start various inspections, disassembly and research on the generated replica in order to confirm whether there were potential hidden dangers or whether there were some hidden secrets.

With a circular scanning terminal around the handheld terminal equipment after a circle, the operator will get its structure, material data model, this speed is absolutely unimaginable if placed on the earth, 3D scanning is a technology that can scan objects in a variety of ways, its physical three-dimensional information into a 3D digital model, which is mainly divided into two types: "contact" and "non-contact" 3D scanning. The difference between these two types, as the name suggests, is whether there is a touching object, touching the object is contacting, and not touching the non-contact.

Tactile 3D scanning technology uses a sensing probe to touch the surface of an object to obtain a coordinate of the point of contact. Because it needs to touch the surface of the object little by little in order, it takes more time to scan the whole object than the non-contact type, but also because it is in contact with the object, so the accuracy is higher (some devices are even as high as 0.1um), and it is widely used for precision measurement and quality inspection. This also means that many delicate parts have no reliable way to do so other than to take them apart and scan them one by one.

Rather than contact, non-contact 3D scanning devices are commonly seen on the market today. Non-contact types are broadly classified into "active" and "passive", and the difference lies in the presence or absence of active light sources. 1. Active, active can be divided into two categories: 1. Time of Flight (also known as depth sensing technology, hereinafter referred to as TOF), the basic principle of TOF technology, similar to bats and dolphins, emits a "wave" to the measured object, and then receives the "wave" that bounces back from the measured object, and calculates the distance of the measured object through the round-trip time of the "wave". At present, most of the TOF technology devices on the market use invisible light (including infrared light, laser light, etc.). TOF technology is also mainly used for large-scale scene scanning, including ranging, building scanning, topographic and landscape surveys, etc.

2) Structure Light, structured light is the mainstream application of 3D scanning technology in the industrial and manufacturing fields. Structured light 3D scanning technology is based on the principle of optical triangulation, composed of optical projectors, cameras, and computer computing systems, and its principle is: the light source projects an image encoded according to certain rules and patterns to the measured object, and the encoded pattern is modulated by the surface shape of the object and produces deformation. The deformed structured light is captured by a camera in another position, and the three-dimensional topography of the object can be determined by the position 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, it is divided into point, line, grating, surface structured light, etc.

The biggest advantage of structured light method is high precision, fast speed, more suitable for short-distance high-precision measurement, but also because of its high precision, high resolution characteristics, at present, structured light is the mainstream technology of industrial and manufacturing applications, according to the projected light source, pattern type, calculation method is derived from fixed and handheld 3D scanning equipment, compared with TOF technology, the shortcomings of structured light method are not suitable for large-scale scanning, but also easy to be affected by the environment and the color of the surface material of the object.

Of course, there are other more convenient methods, and the most representative technique for passive 3D scanning is photogrammetry. Photogrammetry is a long-standing technique that has been used for topographic surveying, surveying, and preservation of historic sites, but in recent years it has also been used as a background for computer games and animations. It is different from the active projection type, which is a method of restoring the 3D three-dimensional model by taking pictures of the same object from different angles through 2D digital images, and then simulating and restoring the 3D three-dimensional model by professional software computational analysis. The biggest feature of photogrammetry is that it does not require equipment such as 3D scanners, and can be made using ordinary photos, but this method can only imitate the shape, and it can not do anything about slightly more precise objects.

Moreover, these 3D printing technologies in the world, even if the military-level high-precision technology is also summarized, cannot achieve the external internal structure data model of the scanning target through integrated scanning, let alone analyze its constituent materials, so this kind of almost "cracked" scanning and copying technology and its equipment, if placed on the earth, it is definitely the dream of the military of all countries, regardless of the stealth fighter of country M or the missile engine of the polar bear, Or Xia Guo's drones and other high-tech, there is no confidentiality in front of this unsolvable technology, if the cost limit is discarded, the other party only needs to get a sample of you, and you can install your new weapons.

Of course, even in the blood seal world, this kind of technology is extremely confidential technology, this cross-era technology of the Xia Kingdom, although the Federation is very eager to find it, the one that Tan Jialiang has mastered may be the last one in the entire Federation, of course, this technology is only unsolvable to the present world, in the space age of this level of the Federation, there are still many targeted prevention methods, such as the simplest one, spraying anti-detection coating on the surface and inside of the equipment that needs to prevent scanning and replication, and when the scanning ray is scanning, What was collected was just a black shadow, and the material data obtained was at most the coated material, and the period when the Federation still existed in various countries before the establishment of the Federation, if the truly advanced equipment was unable to contact the authorized users and deployers for a certain period of time, it would directly self-detonate on the spot or destroy all functional chips, so that the enemy's follow-up search forces and R&D troops could not do anything.

As the scan was completed, an identical replica was born, but when Europa's scientists and engineers had repeatedly dismantled and researched and cracked it, they could only shake their heads at the female officer in charge of the "recycling" program.

"No matter from which angle and technical means, this device can only be said to be very primitive AI, and its storage core is some experimental data that has no breakthrough value at the first glance, we have found a few "Eden" spaceship structure diagrams and scientific research project lists, but there are no classified documents related to the Unity Church and the Federation, of course, we are starting to check whether there is any encrypted information in those daily logs and files, but it will take some time. “

Listening to the report of the person in charge of the inspection department, this officer has actually roughly understood the results of the investigation, excluding the slight possibility of finding out the encrypted documents in the future, Du Jin's identity does not seem to be a problem, according to the officer's intuition, instead of staring at Du Jin, a "dull" researcher, it is better to arrest the former Xia Guo officer named "Li Mengyan" and investigate, the same woman's sixth sense and intuition as a veteran of the intelligence department, this woman is definitely more secret than Du Jin, But she knew very well that the Governor had no intention of investigating "Li Mengyan", a former Xia State officer, but rather a wooing effect.

"Forget it, my mission has been completed, and the rest will be left to the Attempt Department to solve! My vacation time is also approaching. ”

After silently resolving herself in her heart, the female officer left the inspection department with the inspection results and data, and walked towards the command platform of Xinggang.
