3D cameras for mobile applications refer to a category of advanced imaging devices designed for integration with smartphones and other mobile platforms. These cameras are developed by various companies worldwide, including major players like Intel (USA) with their RealSense technology, and STMicroelectronics (Switzerland/France) offering Time-of-Flight (ToF) sensors. They serve industries such as augmented reality (AR), virtual reality (VR), robotics, and automotive by providing depth-sensing capabilities. Key products include compact depth sensors, structured light modules, and stereo vision cameras, enabling features like facial recognition, 3D scanning, and gesture control in mobile devices.
