| 摘 要： | 提出并实现了一种基于特征的全景图拼接算法,该算法应用sobel算子对待拼接的两幅图像分别进行处理,以获取图像边缘及特征点,确定两幅图像重叠部分的灰度差以去除伪特征点并消除外界噪声,选取方差最小的两组特征点作为缝合点,从而确定两图像的相对位置,通过对图像重叠部分进行平滑处理实现了全景图的无缝生成。实验结果证明算法合理,运算速度快,效果良好。

| Abstract: | A panorama algorithm based on feature is proposed,In which image edges are determined by process with Soble operator,feature points were got from edges.Fake feature points and exterior noise were eliminated by confirming the difference of gray-level between the two images.Stich point was determined by minimum variance of two group of feature points.Panorama mosaics is accomplished through fusing process in overlapping area after cngfirming the comparative position of two image.Experiment result shows that the algorithm is reasonable and effective. |
