uavproduct's Introduction

#UAVProduct
处理无人机影像的代码,使用了OpenMVG,openMVS以及GDAL库等,实现影像几何校正,影像拼接,点云生成等功能
##1 处理流程

  • 构建全局影像参数
  • 影像列表的构建以及各个文件夹的生成
  • 影像特征点的解算
  • 影像特征点的匹配
  • 影像光束法平差
  • 影像拼接得到DOM和点云数据

2处理流程详细说明

2.1 影像列表的构建

这一步主要是进行一些估计和一些预处理的操作,实际上包括构建影像列表,解析POS数据得到处理影像大小得到影像的内参数据等, 在这一步中要获取影像的基本信息,并构建列表方便解算,另外在存在POS的情况下可以通过焦距和航高以及POS数据估算影像实际 的地面范围,然后将地面范围以KML数据的形式输出方便查看,同时估算拼接后影像数据大小

2.2 影像特征点的解算

2.3 影像特征点匹配

2.4 光束法平差的SFM过程

2.5 影像拼接

2.6 密集点云的生成

3 安装与编译
