Several sets of external parameters of the camera corresponding to the 2D images are estimated. A 3D information respectively corresponding to the N depths of the first 2D image at each pixel or block is calculated. A proper depth of each pixel or image block is determined. Through the internal parameters, the external parameters, and the N depths, each pixel or image block of the first 2D image is projected onto N positions of the second 2D image, so as to perform a matching comparison analysis with the second 2D image, thereby determining the proper depth from the N depths. | 07-02-2009 |
20100014781 | Example-Based Two-Dimensional to Three-Dimensional Image Conversion Method, Computer Readable Medium Therefor, and System - An example-based 2D to 3D image conversion method, a computer readable medium therefor, and a system are provided.
