Abstract: Implementations of the present application describe updating tile maps in virtual maps, including the following. A central area in which a virtual object is located is determined in a first area. The first area comprises an area of a map that includes tile maps loaded into a virtual map including the virtual object. A border of the central area is located in the first area. A distance parameter is determined after the virtual object moves out of the central area. The distance parameter indicates relative distances of a tile map containing the virtual object relative to the central area in x-axis and y-axis directions. A loading status of a tile map not shared by the first area and a second area is updated based on the distance parameter. The second area comprises a map area determined after moving the first area based on the distance parameter.

Abstract: A method for real-time volumetric 3-D reconstruction of an object uses at least one depth sensor camera. In a preparation step, voxels are collected in a reconstructed scene depending on a new depth map frame, and the collected voxels are cached in order to perform an update of the reconstructed scene. In an integration step, the collected and cached voxels of the preparation step are updated with a newly captured depth map frame. However, the preparation step, and the integration step are separated from each other so that both steps can be carried out in parallel, and at the same time.
