| 摘 要： | 提出了一种基于特征点自动匹配的图像拼接算法，采用改进的Harris算子提取特征点，保证了提取的效率和精度，根据互相关的双向匹配实现对应特征点的自动匹配，从而建立参考图像与当前图像的对应点对，最后采用最小二乘方法得到图像间的全局变换参数，实现图像的拼接。

| Abstract: | An image mosaic algorithm based on feature points auto-motching is presented. The feature points are extracted by the improved Harris detector for improving efficiency while keeping the accuracy simultaneously. Bidirectional cross-correlation is used for feature points auto-matching and the transformation parameters are estimated from the correct corresponding points via the least square method. |
