The system has three main steps:
Step 1. Make fragments: build local geometric surfaces (referred to as fragments) from short subsequences of the input RGBD sequence. This part uses RGBD odometry, Multiway Registration, and RGBD integration.
The tutorial uses the 016 sequence from the SceneNN dataset. The sequence can be found from SceneNN oni file archieve. The oni file can be extracted into color and depth image sequence using OniParser from the Redwood reconstruction system. Alternatively, any tool that can convert an .oni file into a set of synchronized RGBD images will work.
Put all color images in the image folder, and all depth images in the depth folder. Run following commands from the root folder.
