After the release of OPPO Find X, the topic of this mobile phone continues. Everyone has benchmarked Find X, another milestone of the Android camp, with Apple's iPhone X. The discussion on the cutting-edge technologies used in the two mobile phones is also The more intense, one of the focal points is 3D structured light technology. It is reported that it is the artificial intelligence leading enterprise to despise technology for the OPPO Find X to provide commercial 3D structured light technology.

As everyone knows, one of the highlights of the iPhone X is to replace the original Touch ID with Face ID. Once this feature is launched, it has caused the mobile phone industry to follow suit. Face ID is an identity authentication method based on 3D face recognition unlock technology. When unlocking a mobile phone, the user only needs to look at the screen, and the Face ID can be unlocked by face recognition. iPhone X is the earliest mobile phone manufacturer to apply 3D structured light technology. For the first time in six months, many Android users have been waiting for a real 3D structured optical Android phone. Finally, OPPO Find X has solved the 3D structure in one fell swoop. The mass production of optical technology on Android phones has opened a new chapter in Android phones.

In actual use, the difference between the two flagship machines is also the focus of consumers. Test data shows that the time to complete a single unlock of iPhone X is about 1 second, sometimes it can't be solved because of the angle and other issues, and the Find X calculation with the Vision Technology 3D structured light algorithm takes only 0.1 seconds. The time when the system and the camera are turned on is basically completed in an instant, the unlocking time is faster than the iPhone X, and the anti-interference ability is also stronger. This amazing performance benefited from the 3D structured light face recognition technology jointly developed by the AI ​​Lab of the Shanghai Software Research Center of OPPO Research Institute and the Vision Technology, which not only allowed the Android camp to catch up with Apple and achieve the anti-over, and this It also established a new standard for 3D structured light face recognition to unlock the industry.

In China, where artificial intelligence technology and applications are developing at a high speed, domestic brands have surpassed the iPhone, which is not surprising. According to the relevant person in charge of Vision Technology, the principle of 3D structured light technology is not complicated. It is to create a 3D depth map of the user's face structure by projecting 15,000 light spots to the face. In order to accurately identify the user's biometrics and quickly compare them with the owner information, a contact-free and safer unlocking is achieved. It is understood that in the development of OPPO Find X 3D structured light face scheme, OPPO is regarded as providing three main algorithm model structures, including multi-scale and multi-feature attention detection model, and mobile convolution based on self-research. Neural network ShuffleNet custom developed in vivo detection model and adaptive network, multi-model fusion identification scheme.

Thanks to the advanced and excellent tuning of the algorithm model structure, OPPO Find X has a 0.1 second unlocking result, the gap between 0.1 seconds and 1 second, not only visually reflects the Vision Technology in 3D structured light technology. The leading edge also sets a new benchmark for the industry. According to industry insiders, contempt has stood at the forefront of the 3D industry chain, and is a mobile 3D vision solution provider with binocular 3D, structured light 3D and TOF 3D with mass production commercial capabilities.
