摘　　要：通过仿射变换对黄瓜茎切片图像进行了配准,该方法实现了序列切片图像的配准。在配准前需人工获取特征点,为减小误差,提出了用最小二乘法求取最优仿射变换参数。采用上述方法,对黄瓜茎切片图像实现了配准,并借助VTK提供的步进立方体算法进行了三维表面重建和显示。Before using affine transformation to realize the series of slices′ image registration, we need to choose features points by hand. In order to diminish errors, we put forward a method of utilizing least squares to calculate the best parameters of affine transformation. The paper takes the cucumber′ stem slices as example to realize the image registration, 3d surfacing rendering and displaying with the help of marching cubes algorithm provided by VTK.
