Part 66: monocular 3D reconstruction point cloud

The principle of monocular 3D reconstruction is similar to that of binocular

The difference lies in ： Monocular needs to calculate the relationship between rotation and translation between reconstructed images every time （RT）, The three-dimensional generation part is not used like binocular through the corrected image SAD Parallax obtained by other methods , It is obtained by triangulation calculation based on matching points , Compared with binocular , The process is more complex , Lower accuracy , It takes longer to calculate . And after the binocular passes through a three-dimensional punctuation , The later time difference calculation and point cloud get very fast .

Probably did a little , Put on the effect , I suggest you to do binocular work directly , This is too hard ！！！

The first one ： Monocular scene map

The second ： Monocular 3D point cloud 1

Third sheets ： Monocular 3D point cloud 2

 

Superimpose multiple depth maps , The effect is not very good , Color represents depth , There are wood and friends to make a better effect , Let's talk about it ！！！
