Depth sensing technology is revolutionizing how machines and devices perceive and interact with the physical world. Unlike traditional cameras that capture flat 2D images, depth sensors capture spatial information, allowing devices to understand distances, shapes, and the three-dimensional structure of objects and environments. This capability is essential in robotics, augmented reality (AR), autonomous vehicles, and many other cutting-edge applications.What is Depth Sensing?
Depth sensing involves measuring the distance between a sensor and objects in its field of view, creating a 3D map of the scene. This is done using various techniques such as time-of-flight (ToF), structured light, stereo vision, and LiDAR (Light Detection and Ranging). Each method has its own advantages, suited for different use cases and environments.
