    摘要: A camera calibration method and medium and a 3-dimensional (3D) object reconstruction method and medium using the camera calibration method are provided. The camera calibration method includes setting a feature track by tracking and matching features in an input image sequence; estimating 3-dimensional (3D) points in relation to the features by initializing a structure and motion of the camera; estimating a pose of the camera by using the 3D points and refining the structure of the camera based on the estimated pose; and refining the pose of the camera.

    摘要: A modeling method, medium, and system. The modeling method identifies a object within an image by detecting edges within the image, determines a complexity of the identified object based upon detected surface orientations of the identified object relative to a defined surface of the image, selectively, based upon the determined complexity, generates one or more surfaces for a 3D model by identifying one or more vanishing points for one or more corresponding surfaces, respectively, of the identified object and respectively analyzing the identified one or more vanishing points relative to respective determined points of the one or more corresponding surfaces of the image, and generates the 3D model by combining the one or more surfaces in a 3D space.
