On May 10th, as the OPPO held a communication meeting and demonstrated progress and achievements in both 5G and 3D structured light, it marked that Apple’s unique 3D structured light technology had officially entered the Android community with a larger user base. Faction. It can be predicted that in the second half of this year, flagship phones equipped with related technologies will start to appear one after another, and OPPO is likely to become the first manufacturer to carry this technology in the Android camp, because OPPO clearly explained the technology at a previous communication meeting. Will be put into commercial use within 6 months.
Before discussing the development prospects, we can briefly understand this technology. The basic principle can be understood as follows: After the structured light projects a specific light information onto the surface of the object, the camera captures the projected information and analyzes the projected surface structure according to the object's structure. The influence of the optical signal is used to inversely estimate the position and depth of the object and restore the stereoscopic 3D structure. As for the information acquisition and reconstruction, the structural speckles used, the structure encoding and the phase shift fringe, and other different technologies also have Different advantages, but this is more profound, we do not need to discuss in detail today.
Speaking of 3D structure, because of the popularity of 3D movies and dual camera phones, many users may wonder what similarities and differences exist between 3D structured light and double camera 3D combined with dual camera images. To some extent, the three-dimensional scene is restored by recording the depth of field information, and the difference lies in the huge difference between the accuracy and efficiency of the two.
The first is the accuracy. The accuracy of the depth information recorded by dual camera can only reach the centimeter level. If it is applied to face recognition, the safety and accuracy of the application will not be able to survive in the absence of other technical assistance. Below, the millimeter-level accuracy that can be achieved with 3D structured light can perfectly complete the complete record of facial information.
Secondly, the method of recording depth information in combination with hardware and software itself is more straightforward. It does not need to synthesize and compare depth and other information in the same manner as dual camera phones. This results in a significant reduction in computational difficulty and an increase in scanning speed. And the dual photo synthesis method requires higher lighting and can not be used normally in the dark light environment, but the 3D structured light technology does not have this problem.
Of course, the 3D structured light is not completely free from disadvantages. The first is because the optical information of the laser speckle is recorded. Therefore, if the external light is too strong, the light waves in different frequency bands in the spectrum may interfere with the recording. Secondly, More importantly, 3D structured light technology has just entered the Android camp. There are many problems in terms of technical difficulty, component cost, and component structure design. The first-in-class manufacturers have their own advantages, but OPPO can take such initiative. The use of new technologies, of which there are forward-looking factors, but also have confidence in their own technology.
There is a misunderstanding here. Many people think that a certain technology, as long as the upstream supply chain technology is mature, manufacturers can use it with ease. It is like asking others, a complicated tool has been created Why do you just use it?
Techniques that are already fully mature or have a lower gold content may be like a screwdriver, and those who get it can know how to use it based on intuition. However, for some difficult or emerging technologies, manufacturers also need technical support when using them. However, some manufacturers immerse themselves in it for a long time. They can easily get started. However, if some manufacturers have limited technology, they need to first look at how others play, and learn by doing.
The reason why it is so difficult is that manufacturers must also strive to overcome 3D structured light technology. On the one hand, the overall screen of attack has gradually squeezed the living space of the border and frontal fingerprint recognition. On the other hand, compared with fingerprint recognition on the back, As far as possible, facial recognition that can be safely unlocked under the perception of the user is really more comfortable for the user.
The ultimate goal of technology development is to better meet the needs of users. This is evident on the OPPO. It provides deep insights into user needs and usage scenarios, making the 3D structure more than merely an unlocking method. It is to consider extending it to more application scenarios, using this technology to bring more and better user experience.
OPPO has now divided the exploration of 3D structured light application scenes into four large blocks according to different scenarios and application areas, including: secure payment, 3D reconstruction, AR, and games. Many of them have made good progress. For example, in which the three-dimensional reconstruction, OPPO combines the two hot technologies of 5G and 3D structured light, successfully achieved the world's first 3D video call based on 5G transmission.
In addition to demonstrating the mature technology of OPPO in 3D structured light, this demonstration also shows that OPPO has a profound accumulation of technology in many forward-looking areas. It is precisely because the research and development of 5G started 3 years ago. When the new technology of 3D structured light has just begun to mature, it can combine the needs of users to develop feature features.
Finally, OPPO stated that it will use 3D structured light technology on commercial terminals for up to six months in the future. It is believed that many of the new machines that have been equipped with this technology will not be able to wait like Xiao Bian. Blacktech has The rest of the performance does not know if it will surprise you.
