- Depth Camera(also: Depth Sensor, RGB-D Camera, 3D Camera)
- A depth camera is a device that captures both standard visual imagery and per-pixel distance information, producing a 3D representation of the scene. Technologies include structured light (projecting patterns and measuring distortion), time-of-flight (measuring how long light…
- Depth Estimation(also: Monocular Depth Estimation, Depth Prediction)
- The computer vision task of predicting the distance from the camera to each point in a scene, producing a depth map in which each pixel carries a distance value. Monocular depth estimation uses a single RGB image (no stereo cameras or LiDAR) and typically relies on deep learning…
- Depth Sensing(also: Depth Perception (computer vision), 3D Sensing)
- The ability of a sensor or system to measure the distance from itself to objects in the scene, producing a depth map or point cloud rather than a flat image. Common approaches include stereo vision (triangulating between two cameras), structured light (projecting a known…
