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(中):
提供了一种使用相机校准方法的相机校准方法和中等和三维(3D)物体重建方法和介质。 相机校准方法包括通过跟踪和匹配输入图像序列中的特征来设置特征轨迹; 通过初始化相机的结构和运动来估计与特征相关的三维(3D)点; 通过使用3D点估计相机的姿态并且基于估计的姿态来改善相机的结构; 并改善相机的姿态。
