Back projecting a part of a point cloud to the photos that contributed to it.

[grahambates-code]

I am a relative novice to this field, so was wondering if anyone could spell out to me both the feasibility and method required to generate a point cloud from a folder of photos, and then , from the input of a camera position and direction looking at the point cloud, generate a list of the photos that contributed to that part of the point cloud?

Yes this is doable.

1. Run OpenMVG on your image folder
2. Parse the sfm_data.bin/json file to get 3d points visibility per image
3. Given an image of a selection of the point cloud sample the image that see that

Hardest part is to make the point cloud selector
