RGB-Depth Camera

A camera that captures both a conventional colour image (RGB) and a per-pixel depth map, usually via structured light, time-of-flight, or stereo sensing. RGB-D cameras are widely used in assistive navigation systems for people who are blind because they enable real-time detection and tracking of obstacles, people, and doorways at usable distances. When paired with an object-recognition model such as YOLO, they allow a robot or wearable to understand not just that something is in front of the user but what it is and how far away.
