Depth Sensing
Depth sensing is a computer vision and sensing technology that measures the distance from a sensor to objects in a scene, creating a depth map or 3D representation. It enables devices to perceive spatial information and understand the geometry of environments, which is crucial for applications like augmented reality, robotics, and autonomous systems. Techniques include stereo vision, time-of-flight (ToF), structured light, and LiDAR.
Developers should learn depth sensing when building applications that require 3D spatial awareness, such as in augmented reality for object placement, robotics for navigation and obstacle avoidance, or autonomous vehicles for environmental mapping. It's essential for tasks like gesture recognition, 3D scanning, and immersive gaming, where understanding depth improves user interaction and system accuracy.
