摘要： Disclosed is a method and apparatus for generating an image. The apparatus includes at least one processor and a memory. The processor is configured to obtain a wide image of an entire region, obtain one or more teleimages of one or more regions of interest (ROIs) of the entire region using a telecamera according to a capturing order of the telecamera determined for the one or more ROIs based on the wide image, match the wide image and the one or more teleimages, warp the one or more teleimages to the wide image based on a result of the matching, and stitch the one or more warped teleimages based on the wide image.

摘要： An image processing apparatus and a method implemented by the image process apparatus generates a vertical disparity map through regression analysis, based on a difference between vertical coordinate values from feature correspondence information of left and right source images. A geometric difference through image warping is calibrated before depth information is restored through depth estimation. Thus, a process of optimizing a camera model may not have to be performed, and occurrence of black areas that may be caused by image rotation may be reduced.
