autostitcher's Introduction

AutoStitcher

This repository is our C++ implementation of the IJCV 2007 paper Automatic Panoramic Image Stitching using Invariant Features.

这是我们项目代码仓库,主要基于Brown在IJCV2007的论文Automatic Panoramic Image Stitching using Invariant Features实现。

算法流程

输入:n(2或3)张有序图片

  • 从n张图片中提取SIFT特征点
  • 使用k-d数算法为每个特征点找到k近邻相似点
  • 针对所有图片
    • 使用RANSAC算法计算特征点匹配对之间的2D映射关系H(单应矩阵)
    • 使用概率模型验证图片匹配对
  • 针对所有图片进行捆绑调整,计算得到相机的三维旋转矩阵角度theta1,theta2,theta3和所有相机的角度f
  • 多通带融合全景图

输出:全景图
