Denser 3D Point Clouds in OpenSfM
We've improved OpenSfM--the technology we use to create 3D reconstructions from images. By adding post-processing, we get denser 3D point clouds resulting in better visualization, positioning, and much more. At Mapillary we build and use OpenSfM to find the relative positions of images and create smooth transitions between them. That process is called Structure from Motion. It works by matching a few thousand points between images, and then figuring out the 3D positions of those points as well as the positions of the cameras simultaneously.
