A method to culling parts of a 3D reconstruction volume is provided. The method makes available to a wide variety of mobile XR applications fresh, accurate and comprehensive 3D reconstruction data with low usage of computational resources and storage spaces. The method includes culling parts of the 3D reconstruction volume against a depth image. The depth image has a plurality of pixels, each of which represents a distance to a surface in a scene. In some embodiments, the method includes culling parts of the 3D reconstruction volume against a frustum. The frustum is derived from a field of view of an image sensor, from which image data to create the 3D reconstruction is obtained.
A method of operating an electronic system to provide information about objects in a physical world, wherein the electronic system comprises active memory and cache memory, the electronic system represents a 3D reconstruction of the physical world as a plurality of blocks, the electronic system comprises a portable, pointable component, based on actions of a user, at a portion of the physical world, and the portable, pointable component comprises at least one sensor, the method comprising:
A system providing a cloud-based service for a plurality of portable electronic devices that track their respective locations with respect to a 3D environment, the system comprising:
A system providing a cloud-based service for a plurality of portable electronic devices that track their respective locations with respect to a 3D environment and represent a portion of the 3D environment within their field-of-views (FOVs) with respect to their respective locations as blocks of 3D reconstruction data, each block of 3D reconstruction data corresponds to a predetermined volume of the 3D environment, the system comprising:
