摘要: 针对在旋转平台上采集得到的多视角数据,提出一种有效的配准方法,同时结合双目立体视觉测量构建了完整的三维重建系统。通过拍摄旋转平台上多个视角下的标定板图像,提取标定板图像角点信息,计算出旋转平台坐标系和摄像机坐标系的空间位置关系,进一步推导出不同视角下的坐标转换关系,从而实现不同视角的数据配准。实验结果表明,基于本配准方法的旋转多视角双目测量系统具有较高的配准精度,能有效用于物体表面三维重建。

Abstract: An effective registration approach was proposed for multiple-view images captured on a turntable. In combination with binocular stereo, a complete system for 3D reconstruction was proposed. The calibration target was mounted on a step-motor-controlled turntable and it was acquired under multiple views. The coordinate transformation between the turntable and the camera coordinate systems was computed by the angular point information on the calibration target. The coordinate transformation among multiple views was used for data registration at the fixed viewpoint. The experimental results show that the proposed registration method achieves high precision and can be effectively used in 3D reconstruction.
