Device and method for obtaining distance information from views |
| abstract |
A device and method for obtaining distance information from views is provided. The method generating epipolar images from a light field captured by a light field acquisition device; an edge detection step for detecting, in the epipolar images, edges of objects in the scene captured by the light field acquisition device; in each epipolar image, detecting valid epipolar lines formed by a set of edges; determining the slopes of the valid epipolar lines. The edge detection step may calculate a second spatial derivative for each pixel of the epipolar images and detect the zero-crossings of the second spatial derivatives, to detect object edges with subpixel precision. The method may be performed by low cost mobile devices to calculate real-time depth-maps from depth-camera recordings. |
