摘要： A method for producing an image with depth by using 2D image includes obtaining a set of internal parameters of a camera. The camera takes at least a first and a second 2D images with a small shift. The first 2D image has N depths, and N≧2. 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.

摘要： A method for calibrating a response curve of a camera is provided. A homography relationship of an image sequence captured by the camera is calculated using a coplanar information including feature correspondence blocks of the image sequence. An intensity mapping function is then obtained from the intensity information of the correspondence blocks according to the homography relationship. The calculation for obtaining the intensity mapping function is significantly reduced by focusing on the correspondence blocks, which can also avoid the problem of outliers.
