VR and AR technology is a technology that has emerged in recent years, it has been popular for a while in the past few years, but it has been silent for a year, especially after the rise of the concept of big data this year, there are few media reports on VR technology, Yang Qing paid great attention to VR technology when he was in college, and also studied some related products in depth, of course, the most important thing is to study VR games.

VR is called virtual reality technology, AR is called augmented reality technology, the difference between these two technologies is that VR technology is to completely establish a virtual world, and AR is based on reality to capture the real scene through the camera, and then load the virtual fans into the real scene, the most common scene used by this technology is the beauty camera, through the processing of the image to make the girl's photos more beautiful, such as skin tone whitening, acne, prints, dark circles, the effect is good, and there are some slimming face, slimming effect, now it is a relatively mature technology,The most typical application in terms of games is the elf go that is popular all over the world.,At that time, in order to play this game, Yang Qing also wrote a virtual positioning software.。

The use of VR is not very common now, the main reason is that the hardware is not mature, there are two main defects of VR glasses, the first defect is that the resolution is too low, with the current universal mobile phone resolution can not show a very delicate scene, in the actual use or with a large sense of grain, will shine into the user's vertigo. Even the specially customized 4K display has some graininess, and it is expensive and cannot be popularized, the second defect is that the device is too bulky, with a single function, although there are now many VR eyes that can make the weight within 100 grams, but wearing it for a long time will still make people feel tired and unable to use it for a long time.

It is also because of these two reasons that VR technology can not be widely used, Yang Qing has specialized in related technologies when he was in college, and whether it is VR or AR, their core technology is picture processing, because whether it is animation, video they are essentially composed of pictures, the more real and realistic the image, the greater the number of frames required, and how to identify and process the image in the shortest possible time This is the most critical core technology, and at present, there are only some top Internet companies that master this core technology, such as Google, Microsoft, Apple and other top Internet companies, and only the three giants of BAT in China have mastered some core technologies.

Yang Qing was exposed to programming during college, and was able to enter the computer major because everyone had a high salary in those years, so easy to find a job, Yang Qing's parents enrolled him in a computer major, after entering the university, Yang Qing had no interest from the beginning, to a strong interest, and could not extricate himself from being addicted to it, not only to lay a solid foundation, but also to like to study the underlying technology, but also because he was obsessed with studying some of the underlying technology, although Yang Qing had a deep attainment in programming, but there was no outstanding work, the only work was a book management software designed in the school programming competition。

This made Yang Qing very unsmooth in the job search process, repeatedly rejected, after meeting the old beggar Yang Qing found that he seemed to have discovered a new continent, 14 programming books, so that Yang Qing indulged in it, unable to extricate himself, every day when he woke up is to read a book, hungry is instant noodles, only 4 hours a day to sleep, the rest of the time is all spent on these 14 books, not only to read, more time for programming, for the actual verification of the knowledge in the book.

Every day, Yang Qing feels that he has gained new cognition, the technology talked about in these books is really amazing, too admirable, a lot of ideas, programming ideas make Yang Qing feel that he has really learned in vain before, these are the real programming techniques, the days go by day by day, Yang Qing and can't remember how long he hasn't gone out, until a violent knock on the door sounds.

"Yang Qing, is you not there?" Yang Qing, if you are not there, please open the door?"

Yang Qing sat in front of the computer as if he was steady, his fingers were flying and tapping on lines of code, and the code on the screen was flowing like a waterfall.

The shouting outside the door continued for a moment to stop, and after a while the door was opened with a "pop".

"Uhhhh As soon as she opened the door, Chen Qian smelled a disgusting smell, as if a salted fish and the old lady's footcloth were fermented in the sauce jar, that smell! Chen Qian quickly covered her nose and saw that the whole room was full of garbage, leftover instant noodle boxes, takeaway boxes, and drink bottles, which were thickly paved, and there was almost no place to put your feet.

At the foot of the room, a figure with his back to himself was sitting in front of the computer, and the screen could not be seen from behind, only the sound of continuous tapping on the keyboard.

"Yang Qing!Yang Qing!Are you Yang Qing?" Chen Qian tried to shout a few times.

The figure in the room continued to tap on the keyboard as if it hadn't heard it.

Seeing that no one answered, Chen Qian couldn't help but increase the volume and shouted a few more times, but there was still no response, which made Chen Qian a little unhappy, making the house like a garbage heap, I shouted so many times, and I didn't squeak, pretending to be deaf and dumb, right? I want to see if you are really deaf or falsely deaf!

The more Chen Qian thought about it, the more angry she became, and she couldn't care about the unpleasant smell in the house at the moment, so she avoided the garbage on the ground step by step, came behind Yang Qing, and reached out and patted Yang Qing on the shoulder.

The next moment, Yang Qing's head turned.

"Ahh

In Chen Qian's eyes, Yang Qing at this time was pale, her eyes were blue, her lips were chapped, and it was really scary to look at her messy hair.

"Ghost, that ghost!" Yang Qing had also recovered from the programming state at this time, and looked at Chen Qian, who was hiding at the door at this time and secretly looking into the house, and said with some puzzlement.

"Are you Yang Qing?" asked Chen Qian weakly.

"Yes, how did you open the door?Are you the landlord?Why haven't I seen you?" Yang Qing turned around and then tapped on the keyboard, and this program was written immediately.

"I'm the landlord's daughter, your lease has passed for half a month, and you don't answer our phone calls, we think you ran away?"

Yang Qing said a little embarrassed when he heard this: "Oh, I'm sorry! I've been so busy this time, I forgot about it, and the rent will be transferred later!"

Hearing Yang Qing's answer, Chen Qian said, "Okay, then you turn quickly!" After speaking, he covered his nose and was about to go out, the smell here was too bad. After just walking a few steps, Chen Qian turned around and shouted: "Fix the sanitation in your house, it's dirty, I'll check it tomorrow, if it's still so dirty, this house won't be rented to you."

"Uh!" Looking at the garbage in the house, Yang Qing also felt a little excessive, this sanitation should indeed be done.
