There is a high probability that the Apple conference will be released on September 12. The news about the new generation of iPhones can be described as divergent. The great god Guo Mingchi released a report saying that Apple did not use the off-screen fingerprint recognition technology because it encountered technical challenges. Mature Touch ID technology, under-screen fingerprint recognition technology may not be perfect in experience. If the news is true, then Apple ’s 10th anniversary celebration of the iPhone, do you want to put a dumb cannon? From the beginning of the forecast of the great god Guo Mingchi that Apple will support the front 3D camera , to the AR Kit function released with IOS 11 in June, plus the recent AR application demonstrations by major developers at home and abroad (such as AR Measure, etc.), this The series of news is like making a fortune for the king of 3D cameras in the field of mobile phones. AR Measure-Developer Laan Labs In particular, the 3D front camera uses face recognition + iris recognition to realize the quick unlock function of user face detection, which will be a hot spot in mobile phones and even the entire smart terminal industry. Regardless of whether such speculation will eventually become a reality, 3D cameras have become the next trend in the development of mobile phone cameras. The current three mainstream 3D imaging technologies are: 1) Structured Light: Structured light projects specific light information onto the surface of the object and is collected by the camera. Calculate the position and depth of the object according to the change of the optical signal caused by the object, and then restore the entire three-dimensional space. 2) TOF (TIme Of Flight, time of flight): through a proprietary sensor, capture the flight time of near infrared light from emission to reception to determine the distance of the object. 3) Binocular distance measurement (Stereo System): Use two cameras to shoot the object, and then calculate the object distance through the triangle principle. Comparison of three 3D imaging technologies As can be seen from the above figure, the advantage of structured light is that it can use lower hardware costs to achieve or even surpass the other 2 3D camera technologies, and it will not be too high in algorithm development. It is predicted that the iphone 8 front 3D camera will use PrimeSense structured light technology. As we all know, Apple's technology is almost not open to the outside world. Since Apple acquired PrimeSense in 2013, the demand for structured light solutions in the international market has been monopolized. At present, domestic mobile phone manufacturers' demand for 3D cameras is also very urgent, and the willingness to follow up is very strong. They began to look for partners that can provide structured light technology in addition to PrimeSense. IPhone8 3D camera module exploded abroad As the first place in the Shenzhen Peacock plan in 2014, the 3D depth cameras Astra, Astra Pro and Astra mini launched by Obi Zhongguang had already completed mass production as early as 2015, and received strategic strategic shares from MediaTek in 2016. It is currently the fourth global manufacturer that can mass-produce consumer-grade 3D sensors after Apple, Microsoft and Intel. It can realize dozens of functions such as face recognition, gesture recognition, human skeleton recognition, three-dimensional measurement, environment perception, obstacle avoidance, following, three-dimensional map reconstruction, etc., and can be widely used in TVs, mobile phones, robots, drones, VR / AR , Smart home security, car driving assistance and other fields. Recently, Obi Zhongguang will launch a new generation of structured light 3D sensor camera products. Compared with the first generation products, it is more compact, the resolution parameters will be higher, and the power consumption will be lower. It will be suitable for mobile phones, tablets, and notebooks. Manufacturers with many small-scale products that require 3D vision are bound to have a huge impact on the design of mobile terminals (especially mobile terminals) at this stage! Obi Zhongguang mobile phone 3D camera product Astra P Astra series depth camera product map and detailed parameters The core 3D computing chip, deep algorithm, and system support SDK in the product are also completely developed by the company. Since its establishment, it has applied for more than 300 domestic and foreign patents. The R & D team has the technical strength from the underlying chip, in-depth algorithms, to systems, frameworks, and upper-layer application support. With Obi Zhongguang's continuous speech in the field of structured light 3D sensing technology, 3D sensor technology has been applied to somatosensory TV, robots, security and other industries. Obi Zhongguang is a global artificial intelligence visual leader combining hardware and software Enterprises will strive to make all terminals understand the world.
