Image mosaicking using a virtual grid

摘要

Systems, methods, and other embodiments associated with generating a mosaic image using a virtual grid are described. In one embodiment, a method includes analyzing, by a processor of an apparatus, a boundary of a requested image to determine source images that collectively form an area that includes the requested image. The method also includes generating, by the processor, a virtual grid from coordinates of the source images by identifying edges of the source images from the coordinates to define rows and columns of the virtual grid within the boundary. The rows and columns of the virtual grid define virtual tiles in the virtual grid.

1. A non-transitory computer-readable medium storing computer-executable instructions that when executed by a computer cause:
analyzing, by at least a processor, a boundary of a requested image to determine source images that collectively form an area that includes at least a portion of the requested image; generating, by at least the processor, a virtual grid from coordinates of each of the source images within the boundary by identifying edges of each of the source images from the coordinates to define rows and columns of the virtual grid within the boundary, and wherein the rows and columns of the virtual grid define virtual tiles in the virtual grid; creating, by at least the processor, a map that indicates which of the source images cover each of the virtual tiles; and generating, by at least the processor, the requested image as a mosaic of portions of the source images constructed based, at least in part, on the map.
