Conrent

  • Class1: 对应视觉slam中ch1、ch2。完成了一个简单的cmake实践
  • Class2: 对应视觉slam中ch3。学习使用Eigen库、以及坐标变换。
  • Class3: 对应视觉slam中ch4。李群与李代数。学习使用李群、李代数的库sophus。在任务6、7中通过使用李代数计算误差,并用pangolin绘图
  • Class4: 对应视觉slan中ch5相机模型、ch6非线性优化。ch5以及task2、3学习使用opencv,进行了畸变矫正、双目相机生成点云。ch6以及task5,学习ceres、g20优化库的使用,以及自己编写的gaussnewton(重点,特别是非线性优化库的使用)
  • Class5: 对应视觉slam中ch7。特征点法视觉里程计。包括ORb提取、单目对极几何部分E恢复R、t,GN法实现BA,以及ICP实现轨迹对齐
  • Class6: 对应视觉slam中ch8。直接法、光流法视觉里程计。实现了光流法和直接法。
  • Class7: 对应视觉slam中ch10、ch11。后端优化的部分,ch10是g2o、ceres与BA,ch11是位姿图。task3是实现直接法的BA。task 10存在一点问题。ch11可以运行
  • Class8: 对应视觉slam中ch12、ch13。ch12是回环检测与词带。ch13是关于建图部分。
