【摘要】 采用三角形法测量物体三维轮廓.对光栅投影条纹图像进行预处理,采用重心法提取条纹中心线位置,可以获得亚像素级的精度.接着修补条纹中心线,求出采样相对偏移量,计算出物体的高度信息.更多还原

【Abstract】 The 3-D profile measurement with triangle method is presented.The sub-pixel accuracy in abstracting the fringe-centerlines can be obtained by the method of barycenter after preprocessing the fringe picture using grating projection.After the repair of the fringe-centerlines,the relative displacement and the object height can be calculated.更多还原
