Detailed Description

Large Scale Dense Depth Fusion implementation.

This class implements a 3d reconstruction algorithm for larger environments using Spatially hashed TSDF volume "Submaps". It also runs a periodic posegraph optimization to minimize drift in tracking over long sequences. Currently the algorithm does not implement a relocalization or loop closure module. Potentially a Bag of words implementation or RGBD relocalization as described in Glocker et al. ISMAR 2013 will be implemented

It takes a sequence of depth images taken from depth sensor (or any depth images source such as stereo camera matching algorithm or even raymarching renderer). The output can be obtained as a vector of points and their normals or can be Phong-rendered from given camera pose.

An internal representation of a model is a spatially hashed voxel cube that stores TSDF values which represent the distance to the closest surface (for details read the [118] article about TSDF). There is no interface to that representation yet.

For posegraph optimization, a Submap abstraction over the Volume class is created. New submaps are added to the model when there is low visibility overlap between current viewing frustrum and the existing volume/model. Multiple submaps are simultaneously tracked and a posegraph is created and optimized periodically.

LargeKinfu does not use any OpenCL acceleration yet. To enable or disable it explicitly use cv::setUseOptimized() or cv::ocl::setUseOpenCL().

This implementation is inspired from Kintinuous, InfiniTAM and other SOTA algorithms

You need to set the OPENCV_ENABLE_NONFREE option in CMake to use KinectFusion.
