3D structured light from testing to launch, investing more than tens of thousands of Find X

As a return to the Find series four years later, the arrival of OPPO Find X has attracted wide attention from the industry and users. The 'front and back non-porous, seamless one' body design, the innovative dual-track predatory structure, And the ColorOS 5.1 AI smart system with excellent user experience has become one of the reasons for users to remember Find X. But what many people don't know is that Find X is the first product of OPPO equipped with OPPO FaceKey 3D structured light. In order to achieve a good user experience of this feature, the product team behind it has put a lot of effort into the functional optimization.

OPPO's exploration of 3D related technology started as early as 2016. Finally, the project team was formally established in May 2017, and the research work on structured light was started. From the official research on structured light technology to the advent of the first product Find X, OPPO FaceKey 3D structured light has undergone a large version of three rounds of hardware iterations, plus multiple DOE verifications in the later period, a total of 10 rounds of attempts before and after, and finally more than 10,000 machines into the reliability test, and OPPO The original intention of doing this is to bring the stunning 3D structured light to the industry.

For structured light, the indicators that measure its actual performance are mainly divided into depth and precision. OPPO has done a lot of calibration work on each module around this aspect, in order to optimize the working state of the module. In order to ensure the actual experience of the user after the product is shipped, the performance of the structured light is always maintained at an optimal state. OPPO also adds a self-calibration test, which is to prevent the user from falling and causing the deformation of the structured light to affect the structural light recognition accuracy.

At present, the OPPO FaceKey 3D structure light has a number of lattices of 15,000, the resolution is up to 1 million, the structural light precision is up to the millimeter level, the security level can reach one millionth, the speed of 3D acquisition and people Face recognition speeds are all up to the millimeter level.

In the face recognition technology section, OPPO FaceKey 3D structured light has achieved the same level of 3D model accuracy measurement in the industry. Before implementing 3D face payment and recognition, it conducted 70,000 3D face data picture tests per person. The number of test samples has reached 7 million, and the number of trainings has exceeded 1 million. OPPO has made so many attempts to ensure that face payment and recognition are foolproof.

In OPPO's view, 3D structured light still has a very large market space in the future. I believe that with more and more applications, 3D structured light will have a very good growth, and OPPO is currently doing work. It is to make the basic performance of 3D structured light and other basic performance, so that it can better support the subsequent application function iteration.
