【摘要】 提出一种利用双目图像以恢复砂轮地貌三维表面的方法,通过基于灰度的面匹配法对双目图像精确匹配,然后利用双目视觉成像原理,求出该样本点在世界坐标系的坐标。在此一系列样本点的世界坐标基础上,可得待恢复区域的三维外轮廓线和外轮廓面,通过面元内插法可以得到三维场景的精确恢复。实验结果表明,该算法能有效恢复砂轮地貌的三维表面信息。更多还原

【Abstract】 A method to reconstruct 3D surface of monolayer grinding wheel topography based on stereo vision is presented. Through precise matching on binocular images with module match method according to grey information , the coordinates in World Coordinate System of sample-points are obtained based on the principle of stereo vision. The contour line and skeleton map are obtained with those coordinates and then a 3D surface is reconstructed accurately by using the surface interpolation method. Experimental result shows that the method can effectively obtain 3D surface of monolayer grinding wheel topography.更多还原
