【摘要】 提出了一种基于三视几何的三维重建方法。该方法首先利用三目视觉系统获取3幅摄像机的标定图,用十字激光器做为结构光投射器,采集重建的鼠标图;然后通过标定图求出摄像机的内外参数和投影矩阵及基础矩阵,对采集的鼠标图像进行预处理,提取出特征点,利用三焦几何原理找出相应的匹配点,求出物体空间坐标,进行拟合完成三维重建;最后,以鼠标为例,通过Mat-lab7.1对整个重建过程进行验证,实验结果表明这种方法能够获得很好的重建结果。更多还原

【Abstract】 A method was proposed to gain 3D reconstruction based on three-view geometry.Three images were obtained to used to calibrate cameras,cross-laser as structure light projector,gained reconstruct mouse’s image.By calibration image,camera’s intrinsic and extrinsic parameters,projective and fundamental matrixes were drawn.The collected mouse images is pretreated to draw refined laser,extracted feature points,find the very appropriate match points by triple burner geometry principle,calculate the coordinates of space points,fitted to complete 3D reconstruction.Finally,as mouse example,verificated the entire reconstruction process by Matlab7.1,experimental results show this method can better restore mouse of 3D information.更多还原
