3D sensing is a technology that allows devices to perceive and measure the three-dimensional shape and depth of objects in their environment. This is achieved using various methods, such as laser scanning, stereoscopic cameras, or time-of-flight sensors. These technologies help create detailed 3D maps, enabling applications in fields like robotics, augmented reality, and autonomous vehicles. By capturing depth information, 3D sensing enhances user experiences in gaming and virtual reality, making interactions more immersive. It also plays a crucial role in industries like healthcare, where it aids in medical imaging and surgical planning. Overall, 3D sensing is transforming how we interact with the digital and physical worlds.
