In 3D computer graphics and computer vision, a depth map is an image or image channel that contains information relating to the distance of the surfaces of scene objects from a viewpoint. The term is related (and may be analogous) to depth buffer , Z-buffer , Z-buffering , and Z-depth . [ 1 ]
The metadata types include: depth map, camera pose, point cloud, lens model, image reliability data, and identifying info about the hardware components. This metadata can be used, for instance, to create depth effects such as a bokeh filter, recreate the exact location and position of the camera when the picture was taken, or create 3D data ...
Another by-product of this technique is a reasonably accurate depth map of the scene. Meaning each pixel has information about its distance from the camera. Facebook is using this idea in its Surround360 camera family to capture 360° video footage that is getting stitched with the help of distance maps. Extracting this raw data is possible and ...
If the scene is illuminated with a sheet of light this creates a reflected line as seen from the light source. From any point out of the plane of the sheet the line will typically appear as a curve, the exact shape of which depends both on the distance between the observer and the light source, and the distance between the light source and the reflected points.
A depth buffer, also known as a z-buffer, is a type of data buffer used in computer graphics to represent depth information of objects in 3D space from a particular perspective. The depth is stored as a height map of the scene, the values representing a distance to camera, with 0 being the closest.
The stereo cameras approach is a method of distilling a noisy video signal into a coherent data set that a computer can begin to process into actionable symbolic objects, or abstractions. Stereo cameras is one of many approaches used in the broader fields of computer vision and machine vision .
