# open3d.integration.ScalableTSDFVolume¶

class open3d.integration.ScalableTSDFVolume

The ScalableTSDFVolume implements a more memory efficient data structure for volumetric integration.

This implementation is based on the following repository: https://github.com/qianyizh/ElasticReconstruction/tree/master/Integrate

An observed depth pixel gives two types of information: (a) an approximation of the nearby surface, and (b) empty space from the camera to the surface. They induce two core concepts of volumetric integration: weighted average of a truncated signed distance function (TSDF), and carving. The weighted average of TSDF is great in addressing the Gaussian noise along surface normal and producing a smooth surface output. The carving is great in removing outlier structures like floating noise pixels and bumps along structure edges.
