Djupbild
Djupbild, or depth image, is a two-dimensional array where each pixel stores the distance from an imaging sensor to the scene point projected to that pixel. The depth information may come from active depth sensors such as time-of-flight cameras or structured-light systems, from laser scanners, or be inferred from stereo vision by matching image features across viewpoints. In many modern workflows, a depth image is paired with a color image (RGB-D), allowing simultaneous access to color and depth for the same scene.
Depth data are typically stored as 16-bit integers representing millimeters or as 32-bit floating-point values representing
Applications of djupbild include 3D reconstruction, object recognition, robotics, autonomous navigation, and augmented or mixed reality.
