With the development of the times, the achievements of modern science and technology are also changing with each passing day. I remember watching childhood Doraemon in my childhood. At that time, we could only look forward to the future as an animator. We could not think of a short period of more than ten or twenty years. The current development of human science and technology has reached such a rapid rate. Many of the things we didn't want to think about before were implemented today. And every time scientific and technological achievements are displayed, I believe everyone is also very excited. I do not know if you have ever wondered what kind of experience you would experience using VR technology to experience technology. Now that the cloud has been removed from the cloud, this has provided us with this opportunity. Now that the cloud is moving softly, the VR experience “Technology Showcase†will be introduced to the exciting moment of technology demonstration with VR perspective. Let us use VR technology to experience technology and see how wonderful the "Technology Show" will bring to us in the virtual world.
Low price strategy of domestic VR mobile phones
Since Facebook's $2 billion acquisition of Oculus VR, an immersive virtual reality technology company, in 2014, the VR boom has begun to slowly sweep the globe. This year is called the first year of VR, and is hailed as a turning point in the development of VR technology. As a result, domestic and foreign companies have expressed their desire to enter the VR field and compete for the VR market. Overseas Oculus and HTC have already released their own independent research and development VR products and received good performance and praise. Sony also announced the first PS recently. The release date of VR has attracted widespread attention from all walks of life.
Compared to the turmoil of these giants in foreign countries, the VR market competition of domestic companies is also filled with smoke, especially in the area of ​​smart phones, but also the major companies work together. According to statistics, China's smart phone shipments in 2015 were 105.1 million units, and by 2016, it had reached 109 million units, achieving a 4% increase. From this perspective, China is still the world's largest smartphone market, accounting for one-third of the world's total shipments of 340.4 million smartphones. According to market research, the reason why China’s smart phones are so hot is mainly their low price strategy. In the market competition, price advantage has played a large role. And if this low-cost strategy is used in the future VR market, will it work?
Low price strategy leads to reflection
Compared to foreign high-quality VR products, the domestic launch of VR products pales in comparison. Domestic VR products are often affixed with pit, hype, follow-up, cottage, low-cost, low-quality labels. Coupled with the domestic mastery of VR technology is still far less mature than foreign countries, capital investment is relatively inadequate. The only thing that can be done is to use the VR boom and gain certain economic benefits in terms of price advantage. However, such an approach is not a long-term solution. If technology and content do not keep up, it will always follow the footsteps of the international giants. Perhaps in the era when VR is not yet popular, many people want to try something new, but again, Do not want to buy foreign high-quality high-quality VR equipment, domestic low-cost VR products will be the best choice. However, Yu Chak and fishery, over time, the low quality, low content and other defects of domestic VR will also be exposed, which will affect the subsequent sustainable development of domestic VR, and exposed more problems.
The first of these problems is that implementing such a low-cost strategy will be detrimental to the healthy development of the entire VR industry in China. This is not an alarmist for the author. Although the current VR technology is developing rapidly, the domestic manufacturers are more aggressive in following the hype. The most common feature is that "lightning does not rain and it doesn't rain." We often see a domestic mobile phone manufacturer that advertises a VR product and advertises its VR technology to its fullest, but in the end? When products are released, they often end up being rushed. Therefore, current domestic manufacturers do not focus their development on VR technology, VR content, and hardware equipment, and they are more focused on immediate interests. Let VR inferior products flood our current domestic market, and even let domestic VRs be affixed with inferior, vulgar and other negative labels. This is actually the major domestic companies should reflect on.
In addition, the long-term production of low-quality VR products is also easy to lose the trust of consumers, it will lose a lot of users. I believe we all know that Sony’s press conference in Shanghai recently announced that PSVR will be launched simultaneously in China and other parts of the world. This news has already been launched, and even the products are not yet seen by everyone. Many people have already shouted. Buy, buy, and buy. This is a lot of consumers trust in the Sony brand, even if Sony put the price higher, consumers think this product is worth the price, and these people are Sony's core users. Where does the core user come from? It depends on the trust between the company's manufacturers and consumers, and the establishment of such trust is to ensure the quality of products, services, hardware and other aspects of the company's products. If domestic manufacturers produce low-priced and inferior products for a long period of time, then the corporate brand will be difficult to turn over, let alone compete with others.
Alliance cloud moves soft "black technology" attention
Perhaps in the VR technology, domestic manufacturers are still unsatisfactory, but in the holographic technology, the 6D holographic optical field technology released in Shenzhen by the Union cloud moving software has received widespread attention from all walks of life. 6D holographic optical field technology is the emerging "black technology" that has been independently developed through the combination of 6D, light field, holographic technology, and AR technology. The process is very rigorous and complicated. It is necessary to record and shoot the AR holographic big spheres produced by the alliance cloud through more than 500 Nikon SLR cameras, and then publish the contents of the recording and shooting to the cloud of the cloud of alliance to organize and integrate. All the details of the shooting objects are planned and finalized, and the complete 6D light field IP content is finally synthesized. The cloud will rely on the world's leading 6D holographic optical field technology and cloud platform, the technology of naked eye, high visual simulation, full time space, all regions and other characteristics, in one fell swoop broke the traditional VR, AR technology for all aspects of human body restrictions. According to League Cloud, the current 6D holographic light field technology has begun to be used in theaters, theaters, commercial conferences, and advertising conferences. It will also expand its scope in the future, so that more audiences can feel together. The black cloud storms the black cloud.
Camera Module is generally composed of the following parts: Lens, image sensor, base bar and line.
If it is a camera module with AF function (generally a mobile phone camera), most of them adopt VCM mode, which has one more coil than the above structure. By adding points to the coil, the lens can move vertically to achieve the function of focusing. In the case of a camera with a shake resistant feature, the lens is also able to move horizontally to achieve an optical shake resistant effect
Camera module selection
The sensor and lens in the camera module usually account for more than 90% of the cost, and the image quality is also determined by them.
First, choose the most appropriate sensor according to the price you can accept, the interface of the motherboard, and the resolution you need to take photos and video
The price of the sensor usually accounts for 40%-60% of the price of the module. In order to ensure that the resolution/frame rate can meet the requirements, sensors with better sensitivity and larger pixel area are selected at a certain cost.
Secondly, according to the purpose of the sensor you need, choose the lens with the appropriate size and field of view Angle. If a lens with a large field of view is needed, you can choose a fish-eye camera (also known as a wide-angle camera). However, for the image taken by the fisheye camera, there will be a distortion effect. In fact, the distortion effect can be corrected by itself.
