Merge point clouds, export to ply

I am trying to do 3D reconstruction of a face.

Ideally, I would like to "merge" point clouds (with textures) from multiple consequent frames (as I move the camera around the object), then export the resulting object as PLY.

Currently in SDK and viewer tool I see only an option to export current single frame. Also I can't find an option to merge the point clouds.

Does that mean I would rather have to use an 3rd party library to achieve this result? If so, could you recommend one? OpenCV?

I can suggest you taking a look at https://github.com/PointCloudLibrary/pcl and https://github.com/IntelVCL/Open3D . I ended up using the second one

Hi @Jiloc
I was also looking into using Open3D for ICP-type stitching. Can you share any of your findings / code?
