Secret IphoneX 3D depth camera
The world-renowned Apple event took place at the Jobs Theatre within the newly built Apple Park. On the occasion of its 10th anniversary, Apple unveiled two groundbreaking products: the most powerful Apple Watch Series 3 Cellular and the Apple TV 4K ever released. The iPhone 8 and 8 Plus were also launched as scheduled, while the highlight of the event was the special 10th Anniversary Edition of the iPhone X, starting at $999 and offering incredible value for money.
The iPhone X featured a range of impressive upgrades, including the A11 64-bit 4-core processor, a stunning 5.8-inch Super Retina full-screen display with a resolution of 2436 x 1125, a rear vertical camera, wireless charging, improved battery life, and a completely redesigned appearance. Most notably, it introduced long-rumored features such as 3D structured light-based Face ID, enabling face unlocking, human recognition, and face payments. This technology, powered by an optical depth camera, marked a major leap in mobile phone design and set new standards for the entire smart device industry.
Obi Zhongguang has developed its own 3D computing chip, depth algorithms, and SDK. With over 300 patents globally, the company has strong R&D capabilities across chips, algorithms, and applications. As a leader in AI, it continues to expand into new areas like mobile phones, retail, and 3D fitting solutions.

**Does the iPhone X use a 3D structured light depth camera?**
From the details shared during the event, it’s clear that the iPhone X’s front camera can capture depth information, which is different from standard 2D cameras. Adding depth data allows for 3D imaging. There are three main technologies for 3D imaging: structured light, TOF (Time of Flight), and stereo vision.
- **Structured Light:** Projects specific light patterns onto an object and captures them to calculate depth based on distortion.
- **TOF:** Measures the time it takes for infrared light to travel to and from an object to determine distance.
- **Stereo Vision:** Uses two cameras to create depth perception through triangulation.
According to technical analysis by Obi Zhongguang, Apple’s implementation uses a structured light system. Their research showed that over 30,000 optical points were captured, indicating a structured light approach. This choice aligns with Apple’s commitment to precision and performance.
Projecting light, capturing 3D data, and processing images
Compared to other 3D imaging methods, structured light offers excellent performance at a lower cost and is easier to implement algorithmically. This makes it ideal for consumer devices like smartphones.
**If Apple's tech is blocked, what can other companies do?**
Apple has historically kept its innovations proprietary. Since acquiring PrimeSense in 2013, it has dominated the structured light market. As demand for 3D cameras grows in smart devices, many manufacturers are searching for alternatives. However, challenges remain—such as production difficulties, poor image quality, and delays in development. These issues risk wasting valuable time and missing critical product updates.
**What are reliable 3D structured light depth camera manufacturers?**
Obi Zhongguang, a leader in 3D sensing technology, has developed several high-performance 3D cameras, including the Astra, Astra Pro, and Astra mini. These products have been mass-produced since 2015 and are now among the top four global manufacturers of consumer-grade 3D structured light sensors. They support applications like face recognition, gesture control, 3D mapping, and more, and are used in smartphones, robots, AR/VR, and smart home systems.
**Which companies have used Obi’s 3D cameras?**
- Alipay’s facial payment system uses Obi’s Astra series 3D cameras.
- HP’s Sprout 2 uses Obi ASG 3D cameras for 3D scanning.
- The Sambo robot relies on Obi Astra for its machine vision.
Over 1,500 companies worldwide use Obi’s 3D sensors, including major brands like Tmall, financial institutions, and leading robot companies. It’s also working closely with top domestic smartphone manufacturers.
Recently, Obi Zhongguang announced a new generation of compact, high-resolution, low-power 3D sensors designed for mobile devices. These will significantly impact the design of future smartphones and tablets.
