Abstract: Provided is a parallax minimization stitching method and apparatus using control points in an overlapping region. A parallax minimization stitching method may include defining a plurality of control points in an overlapping region of a first image and a second image received from a plurality of cameras, performing a first geometric correction by applying a homography to the control points, defining a plurality of patches based on the control points, and performing a second geometric correction by mapping the patches.

Abstract: Provided are a texture mapping method using a reference image, and a computing apparatus. In detail, a texture mapping method may provide color continuity using a reference image and a target image with respect to each triangular face without analyzing a spatial configuration of a three-dimensional mesh model, thereby reducing a sense of color difference with respect to a texture, and improving quality of the three-dimensional mesh model.
