Title: METHOD AND DEVICE FOR DETECTING PLANES AND/OR QUADTREES FOR USE AS A VIRTUAL SUBSTRATE
Abstract:
An electronic device: displays, on a display of the electronic device, a reticle element in a first appearance state overlaid on a media capture preview of objects in a field of view of an image sensor of the electronic device, where the media capture preview changes as the objects in the field of view of the image sensor change; detects a plane in the media capture preview; and, in response to detecting the plane, displays, on the display, the reticle element in a second appearance state overlaid on the media capture preview, where the reticle element corresponds to an indication of a portion of the extent of the plane while displayed in the second appearance state. An electronic device: obtains a plurality of sets of images; synthesizes a three-dimensional point cloud for each of the plurality of sets of images; constructs planes using the respective three-dimensional point clouds; and generates a merged set of quadtrees characterizing a merged set of planes across the three-dimensional point clouds.
